A Music Therapy Treatment Protocol for Acquired Dysarthria Rehabilitation

Authors:

Abstract

Dysarthria is a common form of speech impairment, affecting 20–50% of stroke patients and 10–60% of traumatic brain injury patients (Sellars, Hughes, & Langhorne, 2002). Very little research has been conducted on the effect of treatments for dysarthria and even less has been reported on rehabilitative music therapy interventions. In the current climate of evidence-based practice (Edwards, 2002) the music therapy profession needs to develop and rigorously test interventions designed to address specific disorders such as dysarthria. This paper discusses theoretical foundations for the use of singing interventions to treat dysarthria and presents a music therapy dysarthria treatment protocol incorporating vocal and respiratory exercises and therapeutic singing.

A Music Therapy Treatment Protocol for Acquired
Dysarthria Rehabilitation

ABSTRACT: Dysarthria is a common form of speech impairment,
affecting 20–50% of stroke patients and 10–60% of traumatic brain
injury patients (Sellars, Hughes, & Langhorne, 2002). Very little re-
search has been conducted on the effect of treatments for dysarthria
and even less has been reported on rehabilitative music therapy in-
terventions. In the current climate of evidence-based practice (Ed-
wards, 2002) the music therapy profession needs to develop and rig-
orously test interventions designed to address specific disorders such
as dysarthria. This paper discusses theoretical foundations for the use
of singing interventions to treat dysarthria and presents a music ther-
apy dysarthria treatment protocol incorporating vocal and respiratory
exercises and therapeutic singing.
Publications on the use of music therapy in neurorehabili-
tation have increased considerably in recent years. However,
a recent review of this literature (Gilbertson, 2004) found
mainly descriptions of clinical approaches and treatment
practices in neurorehabilitation with little outcome-based ev-
idence for treatment. Limitations reported in this review in-
clude inconsistencies or omissions in recording neurodiagnos-
tics, applications of other concurrent therapies, assessment
tools used, and time elapsed between injury and therapeutic
music intervention (Gilbertson, 2004).
So far, only a small body of music therapy research exists
in the area of communication rehabilitation. Preliminary find-
ings have indicated that music therapy techniques, such as
singing and vocal training, can assist in rehabilitation of com-
munication disorders (Adamek, Gervin, & Shiraishi, 2000; Co-
hen, 1992); however, further research on particular music
therapy interventions to address specific communication dis-
orders is needed.
The purpose of this paper is to present and discuss a music
therapy protocol to treat the various symptoms of acquired
dysarthria, including intelligibility, rate of speech, communi-
cation efficiency, fluency and naturalness. The findings of case
study research assessing the efficacy of this protocol are pub-
lished elsewhere in greater detail (Tamplin, in press). It is im-
portant to understand the neurophysical factors of dysarthria
that inform music therapy intervention and influence treat-

quency of intervention, and the method of evaluation chosen.

a music therapy protocol to treat the various symp-
toms of acquired dysarthria, including intelligibility,
rate of speech, communication efficiency, fluency
and naturalness.
Dysarthria
Dysarthria refers to a group of motor speech disorders in-
volving disturbances in control of the speech musculature as
a result of nervous system damage (Abbs & De Paul, 1989).
There is a particularly high incidence of dysarthria following
acquired brain injury as dysarthria may result from damage to
a number of areas in the brain including the upper or lower
motor neuron system, the cerebellum, the extrapyramidal sys-
tem or a combination of these (Sarno, Buonaguro, & Levita,
1986; Sellars et al., 2002). Clinical presentation may include
impairments in the movement and coordination of speech
musculature in terms of strength and tone, and impairments
in range, timing, speed and steadiness of movement (Darley,
Aronson, & Brown, 1975). In particular, dysarthria is often
characterized by reduced verbal intelligibility, voice volume
or range, abnormal rate of speech, and poor prosody, which
in combination often impair speech naturalness.
The sequelae of dysarthria and its neurological foundations
distinguish it from other neurological speech and language
disorders such as apraxia and aphasia. These higher-level rep-
resentational communication disorders are associated with
temporal lobe lesions in the language dominant hemisphere.
Aphasia is a neurological language processing disorder in-
volving difficulty formulating and/or interpreting words and
sentences (Brookshire, 2003). Apraxia is primarily a motor
planning problem and not a problem with the muscles them-
selves; thus, the apraxic speakers’ articulation and prosody are
abnormal, but phonation and resonance are usually unaffect-
ed (Brookshire, 2003). The articulatory inconsistency in aprax-
ic speech is seen through correct articulation of phonemes at
one time and incorrect articulation of the same phonemes at
another time (Darley et al., 1975).

In spite of the prevalence of dysarthria, little research exists
into clinical treatment for this disorder (Kent, 1994; Pilon, Mc-
Intosh, & Thaut, 1998). A systematic Cochrane review of re-
search into the effects of speech and language therapy for
dysarthria due to non-progressive brain damage found no con-
trolled trials, which is a requirement for a Cochrane review
(Sellars et al., 2002), indicating a need for more well-designed
research studies.
Music Therapy and Speech Disorders
Cohen’s (1992, 1994, 1995) seminal body of research in-
vestigating the effect of singing instruction on people with
neurogenic communication disorders in the late eighties and
early nineties has made a significant contribution to our un-
derstanding of the therapeutic effects of these techniques. Sub-
sequent research has expanded on these findings. In summary,
results of music therapy singing interventions have included
improvements in vocal range, intensity, rate, intelligibility, in-
tonation, and reduction in pause time (Adamek et al., 2000;
Baker & Wigram, 2004; Cohen, 1994, 1995; Cohen & Masse,
1993; Haneishi, 2001). However, as these studies do not dif-
ferentiate between types of communication disorders in the
inclusion criteria, it is difficult to explain a treatment effect
that is relevant to a particular neurological condition or
speech disorder. Early publications described music therapy
interventions without reporting treatment outcomes (Lucia,
1987) or claimed positive effects of singing for communica-
tion without research evidence or description of techniques
used (Claeys, Miller, Dallow-Rampersad, & Kollar, 1989).
Neural mechanisms used for motor speech, such as use of
the respiratory muscles and articulators, are shared by both
singing and speech, as are many other elements including
rhythm, pitch, dynamics, tempo, and diction.Through singing,
it is possible to address a range of factors that may affect
speech production, including rate of speech, articulation,
breath control, and prosody. As the melodic line of a song
often contains a greater number and range of vocal frequen-
cies than a spoken phrase, singing may help to change or
increase the range of pitches available to a person with limited
or abnormal vocal range (Cohen, 1994) or increase respiratory
capacity, control, and vocal intensity (Livingston, 1996). Like-
wise, rate of speech may be addressed through modifying tem-
po when singing songs (Cohen, 1988).
Theoretical Foundations for the Use of Music Therapy in
Dysarthria Rehabilitation
The rationale for music therapy treatment for dysarthria is
supported by biomedical theories suggesting that neurophys-
iological processes may be activated through musical stimu-
lation and used to effect non-musical behaviour (Taylor, 1997;
Thaut, 2000). Growing evidence suggests that considerable
cortical reorganisation is possible following neurological trau-
ma (Kolb & Gibb, 1999; Mateer & Kerns, 2000), where parts
of the brain may take over the function of other damaged parts
of the brain. It has been argued, however, that changes in the
cortex are driven by the activation of new motor skills not
simply by motor use (Mateer & Kerns, 2000; Nudo, Barbay,
& Kleim, 2000). Music therapy provides a varied range of ther-
apeutic activities for activating motor skills that may assist pa-
tients to develop these neural interconnections (Baker & Roth,
2004). To increase strength of the articulator muscles, stimu-
lation of movement at appropriate velocity with correct move-
ment patterns and with sufficient contraction to engender neu-
ral adaptation is necessary (Van der Merwe, 1997). By moving
the articulators through a variety of movements that mimic
speech, it may be possible to create neural adaptation nec-
essary to strengthen dynamic articulator muscle activity.
Rhythm and Cortical and Physiological Function
Rhythm is processed diffusely in the brain and does not
depend on any single motor modality (i.e., rhythm can be
produced by hands, feet, head, body, or voice); therefore,
even severe neurological damage does not completely impair
rhythmic processing (Sacks, 1998; Thaut, 2003). The relation-
ship between the neural processing of rhythmic auditory stim-
ulation and cortical arousal of the motor system has been
demonstrated in numerous studies (Thaut, 2005a). In partic-
ular, rhythmic auditory stimulation has been shown to stimu-
late the motor system and facilitate improved movement ef-
ficiency in terms of organization and timing of muscle move-
ments for people with neurological damage (McIntosh, Thaut,
Rice, & Prassas, 1995; Thaut, McIntosh, Prassas, & Rice,
1993). As dysarthria is a motor speech disorder, it is suggested
that rhythmic cuing can stimulate and organise movement of
the speech musculature. Research supports the use of rhyth-
mic cues to control rate as well as facilitate initiation of
speech for dysarthric speakers (Hammen, Yorkston, & Minifie,
1994; Yorkston, Hammen, Beukelman, & Traynor, 1990). Sing-
ing often replicates natural speech rhythms. For people with
a neurological communication disorder, rhythm in a musical
or song context may be easier to imitate and maintain than
the rhythm of isolated speech.
Singing, Respiration and Physiological Function
During controlled breathing (e.g., during singing), the cortex
takes over direct control of the respiratory muscles by imposing
timing priorities on the pace and strength of contractions. In ad-
dition, the intratracheal pressure during singing is approximately
4 times greater than that during normal conversation (Livingston,
1996). Therapeutic singing exercises can, therefore, assist patients
to develop muscle control, expand lung capacity, and increase
vocal intensity. Patients are also able to organize their breathing
and phonation to the rhythmic structure of the music and, thus,
participate for longer periods before fatiguing. By practicing the
distribution of breath when singing a musical phrase, patients
may increase respiratory capacity.
Singing familiar songs is also a motivating way to practice
articulation, phonation, and voice projection. The act of singing
promotes active movement of the facial muscles and articulators
that may assist articulation as well as facilitate the improvement
of non-verbal aspects of communication (Haneishi, 2001). Pa-
tients with diminished muscular control may benefit from vocal

exercises that emphasize consonant articulation and a variety of
consonant–vowel combinations. Abnormal stress patterns com-
mon in dysarthric speech may be due to poor loudness and
frequency variation and durational adjustments. Normal stress
patterns are incorporated into song lyrics in the form of rhythm,
melody, and meter and can be used in therapy to facilitate im-
provements in speech naturalness (Tamplin, 2005).
A Music Therapy Treatment Protocol for Dysarthria
Based on the foundation of previous research (Brookshire,
2003; Darley et al., 1975; Rosenbek & LaPointe, 1985; York-
ston, 1996; Yorkston & Beukelman, 1981) and clinical expe-
rience in this area, a music therapy protocol was designed to
treat dysarthric speech. The protocol involved 24 individual
music therapy sessions over 8 weeks. Previous research has
highlighted the efficacy of frequent sessions over a short pe-
riod of time (Cohen, 1992; Darrow & Cohen, 1991; Darrow
& Starmer, 1986). Individual treatment was chosen rather than
group treatment to allow the use of patient-preferred music to
form the basis of the singing intervention. The presenting fea-
tures of dysarthria may differ between patients and between
different dysarthria types. Therefore, individual treatment ses-
sions allowed the clinician to identify specific problem areas
and progress at an appropriate pace for each patient, focusing
on areas of difficulty within the treatment protocol.
As fatigue is a significant issue for people with neurological
damage (Fletcher, 1992; Kennedy, Pring, & Fawcus, 1993),
session length was carefully considered when designing the
protocol and 30 minutes was deemed as appropriate. Previous
research suggests that patients with acquired brain injury re-
port increased fatigue and perform more poorly after 40–50
minutes of music therapy intervention (Baker, 2004).
The treatment protocol was designed to holistically address
all aspects of motor speech affected by dysarthria, including
respiration, phonation, articulation, resonance, and prosody.
Vocal exercises included physical preparation, oral motor re-
spiratory exercises, rhythmic and melodic articulation exer-
cises, rhythmic speech cuing and vocal intonation therapy
(see Appendix A) and took approximately 20 minutes to com-
plete. These exercises were designed to develop control and
strength in the muscles and mechanisms used for speech and
were kept short and varied to minimize fatigue and maximize
concentration and participation. Following these exercises,
patients sang three familiar songs together with the music ther-
apy clinician. The patients were encouraged to incorporate
strategies to improve intelligibility that had been practiced in
the preceding exercises into their singing. Therapeutic tech-
niques to maximize performance such as feedback, encour-
agement, prompting, and modeling were employed where ap-
propriate. The music therapy clinician provided guitar accom-
paniment for the songs and as much or as little vocal support
as deemed appropriate for each patient.
The frequency of sessions in clinical practice is significant.
In clinical situations where multiple sessions per week are
impractical, the use of a practice CD with exercises for the
patient to use between sessions may be beneficial. Obviously
live music therapy intervention is preferable so that the exer-
cises can be adapted to suit the changing needs of individual
patients. However, in the real world, a practice CD developed
by the music therapist may be needed to supplement music
therapy sessions.
Preparation Exercises
It is important that the client is relaxed before beginning fo-
cused voice and speech exercises. Preparation exercises were,
thus, considered important and were conducted at the start of
each session. These exercises focused on body awareness, gen-
eral muscular relaxation, and warm-up exercises for the muscles
to be used in the remainder of each treatment session (see Ap-
pendix A). By gently stretching the neck, jaw, and tongue mus-
cles and encouraging diaphragmatic breathing, these preparation
exercises aimed to help reduce tension and move focus away
from the larynx to the respiratory system.
Oral Motor and Respiratory Exercises
Oral motor and respiratory exercises (Thaut, 2005a, 2005b)
aimed to develop breath control and increase respiratory ca-
pacity. By facilitating the exchange of greater volumes of air
during the respiratory cycle, the breathing rate is reduced, thus
allowing a longer expiratory phase. Increased breath control
allows the patient to have better control of the expiratory pul-
monary pulses that represent the driving force required for
sustained vocal fold vibration (Kotby, 1995). Gentle phonation
and humming exercises were included to facilitate decreased
tension in the laryngeal areas. The vocal cords barely adduct
during humming (Yiu & Ho, 2002), so this is an appropriate
gentle warm-up for the vocal cords. The alternation between
sustained unvoiced and voiced audible exhalations (e.g.,
shhhhhhhh and ahhhhhhhh) aimed to develop increased lung
capacity and muscular control. Pulsed exhalations (e.g., sh-
sh-sh-sh) were included to develop the intercostal muscles
used in diaphragmatic breathing (see Appendix A). With better
control of expiratory air, more appropriate timing between ex-
halation and onset of phonation is facilitated (Kotby, 1995). In
addition, greater breath control can assist the patient to
achieve an appropriate range of pitch variation.
Rhythmic Articulation Exercises
In order to build on respiratory control and strength, rhyth-
mic articulation exercises also included strong rhythmic pulse
cues to structure vocalizations. Rhythmic chanting of vowel
sounds focused particularly on vocal fold movement and co-
ordination between expiration and onset of phonation (e.g.,
i—eeee . . . i—eeee . . . i—eee ...).Asdysarthria is often
characterized by slurred-sounding speech, efficient vocal fold
closure is necessary to facilitate clear cessation of phonation.
Melodic Articulation Exercises
Melodic exercises using vowel-consonant blends were in-
troduced in order of articulatory difficulty (see Appendix A).
These assisted articulation by practicing positioning of the
speech apparatus and promoting active movement of the fa-

cial muscles and articulators. The melodic component of these
articulation exercises was considered important to extend
pitch range and control and, thus, improve the monotone
quality of speech that is a common feature of dysarthria.
Rhythmic Speech Cuing
Rhythmic Speech Cuing (RSC) is based on research suggesting
that rhythm stimulates arousal of the motor speech system and
organizes motor behaviour. In this protocol, RSC involved the
use of strong rhythmic pulse and emphasis of natural speech
rhythms to cue more normative speech patterns. The rhythmic
cues were provided at an appropriate rate for each patient, but
the use of rhythm to create stress was a stronger focus than rate
control. RSC exercises were based on contrastive stress drills (Ro-
senbek & LaPointe, 1985) and involved rhythmic chanting of the
same sentence in different ways. The clinician provided a strong,
consistent rhythmic pulse and modeled the sentences with em-
phasized use of rhythm, stressing a different word on each sen-
tence repetition (e.g., Week 1—I don’t know, I don’t know, I
don’t know and Week 8—Ican’t believe you said that, I can’t
believe you said that, I can’t believe you said that, I can’t believe
you said that, I can’t believe you said that, I can’t believe you
said that). The use of a constant pulse with these chanted sen-
tences means that the strong beat falls on a different word with
each repetition (sometimes necessitating an anacrusis) and a
change in the rhythm of the words.
Vocal Intonation Therapy
Research has suggested that the use of melodic contours
reflecting the prosodic elements of natural speech may facil-
itate more appropriate vocal intonation (Baker, 2004; Cohen,
1994). In this protocol, vocal intonation therapy involved sung
phrases similar to melodic intonation therapy sentences but
was used to address different goals. Sentences were set to
music using the principles of melodic intonation therapy,
where the melody, rhythm, meter, and accents of the music
phrase reflect the inflection, rhythm, and stress of natural
speech prosody (see Appendix B). The exercises aimed to in-
corporate goals from each of the preceding exercises (e.g.,
expanding respiratory control, improving vocal intensity and
pitch range, incorporating rhythm to structure normal stress
patterns, and practicing articulation). The exercises involved
sung sentences that increase gradually in length (e.g., A wood-
en table. They used a wooden table. They used a wooden table
with four chairs.), and sentences that practice a particular pho-
neme repeatedly (e.g., The jug of juice was just made).
Therapeutic Singing
Therapeutic singing incorporates components of each of the
preceding exercises simultaneously to reinforce therapeutic goals
through the creation of a musical product. It utilizes the often
pleasurable and motivating qualities of singing songs to facilitate
and guide improved speech production. In addition, the use of
familiar and preferred songs often facilitates automatic genera-
tion of words and melody and reduces the need for cognitive
involvement (Prior, Kinsella, & Giese, 1990; Samson & Zatorre,
1992). Therapeutic singing can be used to build muscle strength
through neural adaptation as the movements involved closely
match the target movements for speech in direction, force, range
and velocity (Van der Merwe, 1997). Based on principles of neu-
roplasticity, therapeutic singing may facilitate the learning of new
motor control patterns and encourage the development of syn-
aptic interconnections that influence recovery.
Song Criteria for Dysarthria Rehabilitation
Characteristics of songs useful for therapeutic singing with
dysarthric patients include slow tempo, appropriate phrase
lengths for individual patients, and appropriate key to facili-
tate maximum pitch range of individual patients. Criteria for
inappropriate songs included complex lyrics or rhythmic pat-
terns, wide pitch range, difficult melodic lines, fast tempo
(avoid rap genre or fast-paced R&B music), and negative lyr-
ical content. The decision to use patient-preferred songs was
based on literature that suggests that patients with neurologi-
cal damage respond well to familiar music as it increases en-
gagement and motivates participation (Baker, 2000, 2004;
Kennelly, Hamilton, & Cross, 2001; Thaut, 2005a). Consider-
ation of lyrical content was also incorporated into the song
selection process as Baker (2004) stated that lyrical themes,
together with musical characteristics, which express negative
emotions may facilitate an increase in the intensity of these
emotions experienced by patients. Where possible, songs
without negative emotional content were used to avoid raising
difficult emotional issues.
Songs with short phrase lengths are best initially for patients
with poor respiratory capacity. For example, ‘‘Hey Jude . . .
don’t make it bad . . . take a sad song . . . and make it better’’
(The Beatles), or ‘‘When you’re weary . . . feeling small . . .
when tears are in . . . your eyes ....I’ll dry them all’’ (Simon
& Garfunkle). When the patient was comfortably accomplish-
ing one phrase group per breath, attention was focused on
increasing the length of phonation of words at the ends of
phrases (i.e., extending the last word of each phrase above for
three beats). Later, as they improved, the tempo of the song
was increased and/or patients were encouraged to attempt
two phrases per breath group. For example, in the song, ‘‘Love
Me Tender’’ by Elvis Presley, the first line of the song is ‘love
me tender, love me true.’’ Initially only the first phrase may
be achieved on a single breath, but later in the treatment, both
phrases may be sung on a single breath. This overt initial focus
on the respiratory components of song singing was intentional
as respiration forms the basis of all other components of
speech and song. Without enough breath support to sustain
phonation for short phrases, it is not possible to address artic-
ulation, resonance, or prosody.
The key of each song was transposed to best match the pitch
range achievable for individual patients. Where necessary the
attention of the patient was drawn to the melodic line and
verbal cues for achieving improved pitch accuracy and range
were provided. In situations where the lyrical line was slightly
more complex or wordy, the patient was instructed to focus
on the rhythm of the words in order to improve articulatory

accuracy. For example, the main line of the chorus in The
Beatles’ song, ‘‘With a Little Help from My Friends,’’ involves
rapid tongue movement to achieve the words ‘‘with a little
help’’ quickly.
For a patient with poor respiratory capacity, songs with
shorter phrase lengths (3–4 syllables) and opportunities for
more regular breaths without disruption of the rhythmic pulse
of the song are appropriate (e.g., ‘‘what . . . would you do
. . . if I sang . . . out of tune...’’[TheBeatles]). For a patient
with good respiratory capacity but with poor respiratory con-
trol, rate control, and articulation, appropriate songs may have
longer phrase lengths (up to 10 syllables). For example in the
song, ‘‘Like a Rollin’ Thunder Chasing the Wind’ (Live), focus
should be placed on the stressed words in each phrase, using
the rhythm of the music to clearly separate the words (i.e.,
. . . like a /rollin’ /thunder /chasing the wind/).
Overuse of the same songs may reduce the therapeutic ef-
fect of the intervention. The introduction of new songs gives
patients an opportunity to practice different speech rhythms
and melodic lines in a new musical context. However, to ob-
tain maximum therapeutic benefit, patients must be given
enough time with each song to feel comfortable singing it and
then be able to focus on strategies for improving speech.
The careful selection of songs for treatment and the in-
formed use of rhythm, melody and stress to reflect natural
speech prosody when implementing vocal exercises are of vi-
tal importance to the success of these interventions. Exercises
or songs that are too difficult, in terms of pitch, tempo, or
lyrical complexity may impede patient progress and poten-
tially decrease motivation for music therapy.
Summary and Conclusions
This paper has outlined a music therapy protocol for the treat-
ment of acquired dysarthria. A clear rationale based on existing
research has been provided for the inclusion of each component
of the treatment protocol presented. Singing is a motivating ther-
apeutic medium for patients in neurorehabilitation. Singing ex-
ercises may bypass the conscious thought processes involved in
more cognitive, traditional speech therapy interventions often
used in dysarthria rehabilitation. Clinicians may also expect
greater fluency and enhanced spontaneity in speech production
when using musical exercises. It is anticipated that the devel-
opment of this dysarthria treatment protocol will provide in-
formed treatment options for music therapists to use in clinical
practice and also stimulate further research in this area.

Appendix B—Examples of Melodic Phrases used in VIT
... Several music therapy protocols have been designed to improve dysarthric speech (see Table 1). Some focus on rate control (e.g., Cohen, 1988;Pilon, McIntosh, & Thaut, 1998;Thaut, McIntosh, McIntosh, & Hoemberg, 2001), others utilize rhythm to organize and improve word articulation (e.g., Cohen, 1992Cohen, , 1995Cohen & Masse, 1993;Kim & Jo, 2013), some focus on prosody and phonation (e.g., Magee, Brumfitt, Freeman, & Davidson, 2006), and others use a combination of singing strategies (e.g., Cohen & Ford, 1995;Tamplin, 2008;Tamplin & Grocke, 2008). ...
... The protocol was designed to address respiration, phonation, articulation, resonance, and prosody. A theoretical rationale was provided for the inclusion of each set of exercises, and the detailed protocol was outlined clearly (Tamplin & Grocke, 2008) and described in line with standard Neurologic Music Therapy technique definitions (Thaut & Hoemberg, 2014). In summary: oral motor and respiratory exercises were used to develop respiratory control and support for phonation; rhythmic articulation and rhythmic speech cuing used the entraining function of rhythm to organize motor speech movements; melodic articulation and vocal intonation therapy used pitch variation in musical exercises to improve speech prosody and pitch range; and therapeutic singing (using appropriately chosen familiar and preferred songs) was used to coordinate breathing, pitch, and rhythm together in a motivational and enjoyable activity. ...

The ability to communicate and make oneself understood is integral to a person’s quality of life. It affects social interaction, educational and vocational opportunities, and ultimately independence and sense of self. Unfortunately, speech production is often impaired as a result of neurological damage (e.g., traumatic brain injury, stroke) or disorders (e.g., Parkinson’s disease). There are many similarities and shared neural mechanisms between speech and singing. For example, both singing and speech utilize rhythm, pitch variation, tempo, dynamics, articulation, and respiratory support. Music therapists manipulate these elements of music when addressing therapeutic goals for people with neurogenic speech disorders. Many clinical protocols to address speech disorders in adults have now been published to guide clinical practice in music therapy. This paper summarizes existing music therapy and singing-based protocols used to address commonly occurring acquired or degenerative speech disorders, namely dysarthria, dysphonia, dysprosody, and apraxia of speech. We examine individual and group therapy protocols used in medical and community settings for people with neurogenic speech disorders caused by traumatic brain injury, stroke, spinal cord injury, and Parkinson’s disease. We highlight the strengths and limitations of these protocols and make recommendations for clinical practice.
... Magee and Andrews (2007) stress the important role that music therapy is starting to play in neurorehabilitation in addressing verbal communication skills. Also, according to Tamplin and Grocke (2008), there are a small but increasing number of publications on the use of music therapy in adult neurorehabilitation; however, there is very little literature pertaining specifically to children and even less that focuses on language and speech impairments. Why is that the case? ...
... However they said they were mixing methods (primarily NMT methods with holistic methods). Several studies were found in the literature that used a combination of techniques (Edwards and Kennelly, 2004) (Tamplin, 2008) (Beathard, 2008. ...

The central focus of this research is to investigate UK practice in the use of music therapy for the neurorehabilitation of language and speech in children and adolescents who have experienced traumatic brain injury (TBI). The literature review looks at a range of music therapy techniques used in neurorehabilitation, including neurological music therapy (NMT) techniques. It also suggests that the recovery from brain damage is different in a child than in an adult, so the music therapy techniques needed may be different. The music therapy work has to take into account many factors affecting the patient's level of recovery, including uncertainty of diagnosis, neuroplasticity, their family, their lifestyle prior to injury, their personality, their determination, the time since injury, their cognitive ability, the frequency of sessions, the need to be flexible and respond in the moment, home programmes and differences with working with different ages. The study shows that UK therapists mix methods. Also, interdisciplinary work, in particular with a speech and language therapist (SLT), is very common and has many benefits, in particular in helping setting goals and in motivating the patient. The research also shows that UK therapists are aware of and do use specific methods such as NMT. The practice of different methods is examined in detail, including more traditional techniques such as songwriting and improvisation which are prevalent in the UK. Therapists often modify techniques to make them more appealing to the younger patients. Both functional and holistic goals are formulated, 3 however holistic goals have a higher priority because UK music therapists are trained as emotional therapists first, there is always a need to address emotional needs, emotional aspects can sometimes aid functional goals, and the reason for referral is often for emotional reasons rather than functional ones, either because the referrers are unaware of the potential of music therapy to address functional goals, or they see this as the role of other professionals such as SLTs.
... Speech-language techniques recommended for pwALS, published MT protocols for bulbar rehabilitation in patients affected by various neurological conditions, were considered [68,[87][88][89]. Exercise IX was adapted from Lyle [90]. ...
... A minimally burdensome for the participants, inexpensive and reliable assessment battery to measure bulbar and respiratory changes in early-and mid-stage ALS was selected, based on the analysis of existing research, including [5,81,85,[87][88][89][107][108][109][110][111][112][113][114][115][116][117][118][119][120][121][122][123]. Taken into consideration were the availability of technical means and local laboratory capacities, as well as local clinical assessment standards, as, for example, nurses being accustomed to routinely measuring Forced Vital Capacity rather than Slow Vital Capacity. ...

Respiratory failure, malnutrition, aspiration pneumonia, and dehydration are the precursors to mortality in ALS. Loss of natural communication is considered one of the worst aspects of ALS. This first study to test the feasibility of a music therapy protocol for bulbar and respiratory rehabilitation in ALS employs a mixed-methods case study series design with repeated measures. Newly diagnosed patients meeting the inclusion criteria were invited to participate, until the desired sample size (n = 8) was achieved. The protocol was delivered to participants in their homes twice weekly for six weeks. Individualised exercise sets for independent practice were provided. Feasibility data (recruitment, retention, adherence, tolerability, self-motivation and personal impressions) were collected. Bulbar and respiratory changes were objectively measured. Results. A high recruitment rate (100%), a high retention rate (87.5%) and high mean adherence to treatment (95.4%) provide evidence for the feasibility of the study protocol. The treatment was well tolerated. Mean adherence to the suggested independent exercise routine was 53%. The outcome measurements to evaluate the therapy-induced change in bulbar and respiratory functions were defined. Findings suggest that the protocol is safe to use in early- and mid-stage ALS and that music therapy was beneficial for the participants’ bulbar and respiratory functions. Mean trends suggesting that these functions were sustained or improved during the treatment period were observed for most outcome parameters: Maximal Inspiratory Pressure, Maximal Expiratory Pressure, Peak Expiratory Flow, the Center for Neurologic Study—Bulbar Function Scale speech and swallowing subscales, Maximum Phonation Time, Maximum Repetition Rate—Alternating, Maximum Repetition Rate—Sequential, Jitter, Shimmer, NHR, Speaking rate, Speech–pause ratio, Pause frequency, hypernasality level, Time-to-Laryngeal Vestibule Closure, Maximum Pharyngeal Constriction Area, Peak Position of the Hyoid Bone, Total Pharyngeal Residue C24area. Conclusion. The suggested design and protocol are feasible for a larger study, with some modifications, including aerodynamic measure of nasalance, abbreviated voice sampling and psychological screening.
... Singing exercises used for the singing intervention group were designed based on the singing intervention protocols of previous studies (Di Benedetto et al., 2009;Haneishi, 2006;Tamplin & Grocke, 2008;York, 2020). They consisted of motor, breathing, vocal and singing exercises, and homework. ...

Background: Although speech and voice disorders are common in Parkinson's disease (PD), there is insufficient evidence to support the effectiveness of behavioural speech therapies in these patients. Aims: This study aimed to examine the effects of a new tele-rehabilitation program, a combining of conventional speech therapy and singing intervention, on voice deficits in patients with PD. Methods & procedures: This study was a three-armed, assessor-masked, randomised controlled trial. Thirty-three people with PD were randomly assigned to the combination therapy, conventional speech therapy, or singing intervention group. This study followed the Consolidated Standards of Reporting Trials guidelines for non-pharmacological treatment. Each patient participated in 12 tele-rehabilitation sessions over 4 weeks. The combination therapy group received speech and singing interventions simultaneously (respiratory, speech, voice, and singing exercises). Voice intensity as a primary outcome and the voice handicap index (VHI), maximum frequency range, jitter and shimmer as secondary outcomes were evaluated 1 week before the first intervention session, 1 week after the last intervention session and 3 months after the last evaluation. Outcomes & results: The results of repeated measures analysis of variance showed a significant main effect of time on all outcomes in all three groups after treatment (p < 0.001). There was a significant group effect for voice intensity (p < 0.001), VHI (p < 0.001), maximum frequency range (p = 0.014) and shimmer (p = 0.001). The combination therapy group demonstrated a significant outperformance in the VHI and shimmer than the speech therapy (p = 0.038) and singing intervention (p < 0.001) groups. The results of this study also indicated that combination therapy group compared to singing intervention group had a larger effect on voice intensity (p < 0.001), shimmer (p < 0.001) and maximum frequency range (p = 0.048). Conclusions & implication: The results demonstrated that combining speech therapy with a singing intervention delivered through tele-rehabilitation might be more effective in improving voice problems in patients with PD. What this paper adds: What is already known on the subject Parkinson's disease (PD) is a neurological disorder that frequently causes disturbances in speech and voice, which negatively affect patients' quality of life. Although speech difficulties occur in 90% of patients with PD, evidence-based treatment options for speech and language problems in these patients are limited. Therefore, further studies are required to develop and assess evidence-based treatment programs. What this study adds The findings of this study showed that a combination therapy program including conventional speech therapy approaches and individual singing intervention provided through tele-rehabilitation may have a greater effect on the improvement of voice problems in people with PD compared to speech therapy and singing intervention alone. What are the clinical implications of this work? Tele-rehabilitation combination therapy is an inexpensive and enjoyable behavioural treatment. The advantages of this method are that it is easy to access, appropriate for many stages of voice problems in PD, requires no prior singing training, encourages voice health and self-management and maximises treatment resources available to people with PD. We believe that the results of this study can provide a new clinical basis for treatment of voice disorders in people with PD.
... Haneishi [11] targeted only patients with Parkinson's disease and demonstrated that singing training improved vocal intensity and speech intelligibility. In a study by Tamplin et al. [12], an improvement in speech naturalness was observed. Kato [13] reported an improvement in singing and speaking range, the vocal intensity of speech, and speech intelligibility. ...

The aim of this fundamental study is to investigate acoustic changes and perceptual impressions by singing and vocal training in 11 dysarthric Japanese patients. We also examined to improve their speech intelligibility through this training. Dysarthria is a speech disorder caused by diseases such as stroke, intractable neurological disease, and sequelae of head trauma. In terms of vocal evaluations, pre-test, mid-test, post-test, and follow-up test were performed quarterly to investigate a correlation between the five acoustic features of the singing voice (i.e. normalized frequency (pitch) score (NFS), normalized rhythm (duration) score (NRS), normalized intensity (power) score (NIS), frequency deviation (FD) and the intensity deviation (ID)) and speech intelligibility. These factors were evaluated based on the perceptual impression of a group of music major students (MS) and a group of non-music major students (NMS). The objective acoustic features revealed that the order of NRS, NIS, NFS, FD, and ID was higher in correlation with human subjective evaluation. The pre-test results of speech intelligibility indicated a greater improvement in the low intelligibility group than in the high intelligibility group. Furthermore, no difference was found in how perceptual impressions were evaluated between the MS and NMS groups.
... Temporal and rhythmic structure of songs induces intrinsic anticipation to enunciate target speech sounds with emphasis and clarity through singing exercises, potentially improving speech intelligibility. In addition, Tamplin and Grocke (2008) explained that during controlled breathing (e.g., during singing), the cortex directly controls the pacing and strength of respiratory muscles contractions. Singing exercises with the songs that provide a rhythmic structure to organize breathing and phonation timing could assist in achieving improved muscle control, expanded lung capacity, as well as increased vocal intensity. ...

Many individuals with Parkinson’s disease (PD) develop characteristics of hypokinetic dysarthria during the course of the disease. As communication skills are predominant factors in everyday life, dysarthric speech symptoms immediately influence decreased competence in communication, thereby increased frustration, and loss of confidence regardless of the degree of symptoms. The purpose of this study was to investigate the feasibility of a group music therapy protocol using Neurologic Music Therapy techniques for treating voice and speech deficits due to hypokinetic dysarthria seen in individuals with PD. Five participants with PD exhibiting characteristics of hypokinetic dysarthria participated in six weekly group music therapy sessions. Three speech assessments were administered as pretest and posttest to assess participants’ improvement in variables that measured vocal function, voice quality, articulatory control, and connected speech intelligibility through acoustic and perceptual analyses. Feasibility and outcome measures provided initial evidence to warrant further study of the protocol.
... It affects approximately 10,000 people in New Zealand, up to 90% of whom experience hypokinetic dysarthria (poor speech quality) and dysphagia (problems with swallowing) (Sapir, Ramig, & Fox, 2008). Preliminary evidence suggests that singing may benefit breath control and capacity, and improve dysarthric symptoms (Azekawa, 2011;Di Benedetto et al., 2009;Elefant, Baker, Lotan, Lagesen, & Skie, 2012;Kondo, 2011;Pachetti 2000;Tamplin, 2008;Tamplin & Grocke, 2008;Yinger & Lapointe, 2012). ...

The CeleBRation Choir, a social singing group for people with neurological conditions and their significant others, is an initiative of the University of Auckland's Centre for Brain Research. A new model of therapy, Choral Singing Therapy, is discussed in the context of literature addressing singing and health, the rehabilitation needs of this population, and related models of music therapy. The paper outlines the choir protocol, supporting guidelines and role of the music therapist leading the choir, with reference to participant interview data from the 2011 SPICCATO (Stroke and Parkinson's: Investigating Community Choirs and Therapeutic Outcomes) feasibility study. Recommendations are provided for people considering social singing groups for this population. Further research is planned, with the intention of recruiting participants to new choirs for a randomised controlled trial of Choral Singing Therapy.

Road traffic accidents frequently result in head injuries, chest injuries or serious cervical spinal cord injuries. Lifesaving assistance such as endotracheal intubation is commonly used. Although vocal cord paralysis during orotracheal intubation is uncommon, it can have catastrophic implications. Very little evidence is available on rehabilitation interventions that combine music therapy, technology devices and audio-visual (AV) aids. In patients with traumatic brain injury (TBI) and cervical spinal cord injury who have vocal cord paralysis, the use of music therapy technology devices and AV aids for rehabilitation needs to be thoroughly tested with goal-oriented, targeted strategies intended to achieve a particular function or skill set. Using technology devices and AV aids help with cognition and communication. Music therapy might be regarded as just as beneficial as speech therapy in enhancing cognitive function. We report a case of a 4-year-old female child with TBI with cervical cord contusion with bilateral vocal cord paralysis successfully rehabilitation along with the incorporation of music therapy, technology devices and AV aids in the rehabilitation programme.

The purpose of this study was to examine the ways music therapists use their singing voices in music therapy sessions and, in doing so, to provide a working definition of the therapeutic singing voice. Four music therapists were observed leading at least 10 music therapy sessions each in order to examine the ways they used their singing voices in clinical practice. Interviews with each of these therapists, at the completion of session observations, enriched these observational data. Data were analyzed in two stages. First, individual singing voice profiles were developed for each music therapist, and second, these profiles were integrated to define essential singing voice characteristics. These characteristics included flexible postures and physicality, diverse breathing methods and strategies of phonation, flexible resonance strategies, improvisational skills, and knowledge of diverse music genres. Implications for vocal education and training in music therapy programs are discussed.

This book integrates neuroscience research on neuroplasticity with clinical investigation of reorganization of function after brain injury, especially from the perspective of eventually translating the findings to rehabilitation. Historical foundation in neuroplasticity research are presented to provide a perspective for recent findings. Leading investigators synthesize their work with research from other laboratories to provide a current update on neuroanatomic features which enhance enuroplasticity and provide a substrate for reorginaization of function. The capacity for recovery from brain injury associated with focal lesions as compared to diffuse cerebral insult is discussed. Interventions such as environmental enhancement and drugs to enhance reorganizatioin of function after brain injury have been studied in animalmodels and in human studies. Methodologies to study neurophysiological measures, trancranial magnetic stimulation, and computational modeling. Implications of neuroplasticity research for innovations in rehabilitation of persons with brain injury are critically reviewed.

The Evidence Based Medicine (EBM)1 framework has been incorporated into the field of healthcare practice over the past decade. Whatever our stance as to its benefits and disadvantages, more and more music therapists in health departments and related clinical posts will be asked to account for their work using this approach to the documentation of clinical effectiveness. It is important that music therapists working within clinical service guidelines understand the framework of EBM and are aware of ways in which they can include its precepts in their justifications for practice and posts. The levels of evidence in an EBM approach are presented and discussed and the issues particular to the application of music therapy research findings are explored. Given the author's experience in paediatric medical settings, some of the examples in this paper will refer to the children's hospital context in particular.

With the advent of modern cognitive neuroscience and new tools of studying the human brain "live," music as a highly complex, temporally ordered and rule-based sensory language quickly became a fascinating topic of study. The question of "how" music moves us, stimulates our thoughts, feelings, and kinesthetic sense, and how it can reach the human experience in profound ways is now measured with the advent of modern cognitive neuroscience. The goal of Rhythm, Music and the Brain is an attempt to bring the knowledge of the arts and the sciences and review our current state of study about the brain and music, specifically rhythm. The author provides a thorough examination of the current state of research, including the biomedical applications of neurological music therapy in sensorimotor speech and cognitive rehabilitation. This book will be of interest for the lay and professional reader in the sciences and arts as well as the professionals in the fields of neuroscientific research, medicine, and rehabilitation.

Melodic Intonation Therapy (MIT) is effective with approximately 75% of people with non-fluent aphasia, who would have otherwise had limited opportunities to develop verbal language vocabularies. The remaining 25% of people with severe non-fluent aphasia remain unable to communicate verbally and rely on other means of communication. Modifying the traditional MIT protocols was found useful in assisting two people with severe non-fluent aphasia to establish a basic form of verbal communication which not only improved their communication opportunities but also their self-esteem. A comparison of the traditional MIT program and the modified version provide a theoretical basis for explaining the success of the modified program. Further research is necessary to establish assessment procedures and to ensure appropriate referrals.

Humming is a conservative voice therapy technique used to facilitate easy and efficient natural voice production. It is a technique used in treating voice disorders due to vocal hyperfunction, vocal abuses and/or misuses. However, few efficacy studies of humming are available in the literature. The present study was a prospective study which set out to investigate the changes in vocal quality demonstrated by eight female subjects with hyper functional dysphonia (six with vocal nodules and two with chronic laryngitis) and eight female subjects with normal voice following two sessions of training using humming per se. Voice recordings were taken before and after the humming exercises. Three judges rated the roughness and breathiness of these samples independently using the GRBAS scheme with a 10-point visual analogue rating scale. Acoustic analyses were also carried out to measure the average fundamental frequency, jitter, shimmer and harmonic to noise ratio. Both groups of subjects demonstrated a significant improvement in perceptual roughness (p <0.05) but no change in the breathiness rating and the acoustic measures. These preliminary findings provide some evidence that humming alone can at least bring about short-term improvement in perceptual rough vocal quality.
