Abstract

Purpose The purpose of this paper is to test the efficacy of an interactive verbal prompting technology (Guide) on supporting the morning routine. Data have already established the efficacy of such prompting during procedural tasks, but the efficacy of such prompting in tasks with procedural and motivational elements remains unexamined. Such tasks, such as getting out of bed in the morning and engaging in personal care, are often the focus of rehabilitation goals. Design/methodology/approach A single‐n study with a male (age 61) who had severe cognitive impairment and was having trouble completing the morning routine. An A−B−A′−B′−A″−B″ design was used, with the intervention phase occurring both in an in‐patient unit (B, B′) and in the participant's own home (B″). Findings Interactive verbal prompting technology (Guide) significantly reduced support worker prompting and number of errors in the in‐patient setting and in the participant's own home.

Abstract
Purpose The purpose of this paper is to test the efficacy of an interactive verbal prompting technology
(Guide) on supporting the morning routine. Data have already established the efficacy of such
prompting during procedural tasks, but the efficacy of such prompting in tasks with procedural and
motivational elements remains unexamined. Such tasks, such as getting out of bed in the morning and
engaging in personal care, are often the focus of rehabilitation goals.
Design/methodology/approach – A single-n study with a male (age 61) who had severe cognitive
impairment and was having trouble completing the morning routine. An A 2B2A02B02A00 2B00
design was used, with the intervention phase occurring both in an in-patient unit (B, B0) and in the
participant’s own home (B00).
Findings Interactive verbal prompting technology (Guide) significantly reduced support worker
prompting and number of errors in the in-patient setting and in the participant’s own home.
Research limitations/implications The results suggest that interactive verbal prompting can be
used to support motivational tasks such as getting out of bed and the morning routine. This study used a
single subject experimental design and the results need to be confirmed in a larger sample.
Originality/value – This is the first report of use of interactive verbal prompting technology to support
rehabilitation of a motivational task. It is also the first study to evaluate Guide in a domestic context.

Introduction
Cognitive impairment mediates disability in conditions where brain function is impaired.
According to the international classification of functioning (ICF; World Health Organization
(WHO, 2002)), higher level cognitive functions, or executive functions, underpin goal-oriented
behaviours,such as abstraction, planning, timemanagement, cognitive flexibility, sequencing,
problem solving and judgement. Deficits of higher level cognitive functions are often
catastrophically disabling (Oddy and Worthington, 2009) and thus require costly carer input.
ATC is the use of technology to extend or augment mental functions, with particular
application meeting the needs of people with cognitive impairment. The use of technology to
extend human abilities is universal. Bows extend the ability to launch projectiles; knives
augment the ability to bite and tear. It can be argued that the peculiar facility for the selection
and assimilation of technology defines humanity (Aunger, 2010; Clark, 2003). In recent
times, digital technology has matured to be sufficiently portable and capacious to further
extend human cognitive function. Smart mobile phones support both communication across
distances and prospective memory through reminders and calendar functions. Despite their
ubiquity these tools have not been widely used by the people who have the most to gain,
that is, people with impairment to their cognitive function. The learning and memory burden
involved the use of early digital technologies is changing, with simpler more intuitive

interfaces being developed. There is currently a burgeoning interest in the field of ATC, as
reviewed in Gillespie et al. (2012). ATC is promising in its development of compensatory
technologies to augment existing or preserved cognitive abilities and has potential to reduce
disability and dependence. The portable or ambient technology can be thought of a
prosthesis or replacement for the specific impaired cognitive function (Cole, 1999).
Gillespie et al. (2012) found that a large proportion of ATC have been used to assist with time
management (33 studies of 91 included studies) and organisation and planning (25 studies
of 91). These domains are highly relevant to activities of daily living.
Time management functions are prospective memory functions that ensure that one
behaviour stops and another begins at a specific time. For example, reminding the user to
leave to go to a doctor’s appointment at a specific time. Time management is the most
common ICF specific mental function targeted by ATC. The largest study in the ATC field is the
Neuropage randomised controlled trial (Wilson et al., 2001), n¼143, which demonstrated the
efficacy of using a paging system to deliver reminders for the performance of everyday tasks
in people with cognitive impairments. The efficacy of pagers to perform this function has also
been demonstrated (Kirsch et al., 2004). Other media have also used text or auditory prompts
to overcome prospective memory difficulties. Voice recorders with a timer function (van den
Broek et al., 2000); text messaging to mobile phones (Pijnenborg et al., 2007); voice
messages to phones (Leirer et al., 1991); smartphone reminders (Svoboda and Richards,
2009) or schedule management software on a palmtop computer (Kim et al., 2000) or PDA
(Davies et al., 2002) also have demonstrated efficacy. We would conclude that proof of
concept is established and that for those with specific prospective memory difficulties,
unidirectional text and recorded prompts to mobile devices are effective interventions.
Difficulty monitoring one’s behaviour can lead to problems performing complex sequences.
Successful sequence performance requires active maintenance of the goal state, most
recent step, correct next step and solutions to problems arising. In contrast with the large
number of studies with the aim of supporting organisation and planning functions, there have
been only a limited number of ATCs developed which provide step-by-step support during
task performance.
Lancioni et al. (2000) developed the VICAID system to be used by people with intellectual
disability to guide them through domestic and vocational tasks. The VICAID system is a palm
top computer with a simplified user interface consisting of a single button, providing visual
and auditory prompts through tasks. Users provide feedback to the system by pressing the
button. VICAID also rewards successful task completion through feedback to the user.
Mihailidis et al. (2008) developed the COACH system to prompt users with dementia through
processes such as hand washing. The latest version of the device uses a camera to capture
visual data on the position of the users’ hands to enable the system to be context aware of
the user’s progress through the task and thus select the appropriate auditory prompt.
The Guide system aims to emulate the verbal support provided by carers (O’Neill and
Gillespie, 2008). Guide provides verbal prompts to orient users to sub-steps, remind users to
perform various checks, and work with users to resolve problems. Users respond to the
prompts using the simple verbal responses of ‘‘yes’’ and ‘‘no.’’ When loaded with a protocol
mapping the action pathway and common problems, Guide is an expert system able to deal
with problems that might arise. The system sequences the task for users in terms of sub-steps,
and for each sub-step, a series of questions are asked. Affirmative responses lead to the next
question or sub-step. Negative responses lead to problem solving sub-routines. Thus,
relatively able users can move quickly through the protocol, while less able users receive more
guidance. The contribution is in the close simulation of carer scaffolding of task performance.
The auditory-verbal interface emulates conversational interaction; does not distract the user’s
visual attention from the task and can resolve commonly arising problems. Guide prevents
errors because it prompts users before each action and thus implements an errorless
learning approach.
O’Neill et al. (2010) examined the use of Guide to aid a complex rehabilitation sequence
(donning a prosthetic limb) in a sample of eight older adults with cognitive impairment of

vascular origin. The system significantly reduced safety critical errors and increased the
accuracy of the rehabilitation relevant sequence. A key outstanding question was the extent
to which Guide generalises to other tasks with different structure. For example, donning a
prosthetic limb is mainly a procedural task, but would Guide also be able to support tasks
which have a larger motivational component? Accordingly, the current study presents data
on the effectiveness of Guide to support the morning routine, a complex sequence with both
procedural and motivational aspects. Guide has previously demonstrated efficacy in an in
patient/hospital setting with persons aiming to learn a rehabilitation task. This study also
examines whether Guide can be an effective support for independence in the less
structured setting of the participants own home post-discharge.

Settings
BA neurobehavioural assessment and rehabilitation unit specialised in the care of persons
with complex needs after brain injury.
BService user’s home.
Design
A single participant A 2B2A02B02A00 2B00 design (Table I) was used to assess the
effectiveness of Guide to support the morning routine of a gentleman with one-year history of
severe haemorrhagic brain injury.
Outcome variables were number of errors made in the sequence and number of
interventions required by rehabilitation support workers to ensure sequence performance.
Following discharge his performance with and without Guide was also assessed via ratings
made by a family member. Thus, the usability and effectiveness in a domestic context was
also assessed.
Participant
Mr M is a 61-year-old single retired electrician. He had one adult daughter who was not a
dependent. He was found unconscious at his home after a presumed collapse. Admission
Glasgow Coma Scale was 3/15 and brain imaging revealed a right intracerebral
haemorrhage affecting the territory of the caudate nucleus and extending into the third
and fourth ventricles. Hydrocephalus and midline shift led to the insertion of an extra
ventricular drain. Initial GCS and duration of PTA placed him in an extremely severe category
of brain injury.
Mr M was admitted to a neurorehabilitation centre at ten-weeks post-injury.
Neuropsychological report at 14 weeks indicated that he had severe impairment of
memory, executive function and visual perception. Impairment of verbal recall of information
was associated with judgement difficulties. He lacked capacity to make legal or financial
decisions as a result. He did not exhibit challenging behaviour and his mood was euthymic
for the most part. Some anxiety was apparent if disoriented to place. Anxiety was also

thought to have had a negative bearing on his sleep pattern and he required zopiclone to
aid sleep onset. There was no evidence of significantly altered personality or current
mood issues.
Medication remained constant throughout the trial and comprised: amlodipine, ramipril,
ibuprofen, trazodone, co-codamol, lactulose, zopiclone, omeprazole, and eumovate.
Mr M was referred to the current project as he was identified by his occupational therapist
staff as having difficulty performing his morning routine, improved by the verbal prompts of
rehabilitation support workers.
Materials
Dell, Precision M4500 laptop.
Guide software loaded with morning routine protocol (Appendix 1).
Acoustic Magic, Voicetracker2 array microphone.
Creative, Inspire T10 speakers.
Morning checklist (Appendix 2) rating measure designed to quantify performance of
morning personal care routine.
Procedure
Mr M was assessed by his occupational therapist who noted omissions of parts of the
morning routine in the context of verbal report that he had completed those steps. The
morning checklist (Appendix 2) was then introduced, to be completed by Rehabilitation
Support Workers each morning. The observer rated the steps in the sequence as follows:
completes step independently (five points); completes step after 1 verbal prompt (4);
completes step after 2 verbal prompts (3); completes step after 3 verbal prompts (2);
requires physical intervention/assistance to start, continue or complete step (1); refuses to
complete step (zero points). Only prompts by human carers were scored, prompts by the
assistive technology (Guide) were not.
Following each morning routine performance in both baseline and intervention, the
participant was asked to rate ‘‘how well did that go?’’ along a five-point Likert scale from
5 ‘‘very well’ to ‘‘1 very poorly’’. This was with the aim of tapping into his perspective on his
own behavioural performance and the support that he received.
Suitability for a trial of Guide was decided by the occupational therapist. The functionally
defined inclusion criteria were that he was able to carry out sequences without errors or
omissions when given verbal prompts by the Rehabilitation Support Workers, but omitted
steps when acting independently.
After a baseline (A) period of six weeks, giving 28 datapoints, Guide was installed in his
bedroom to automatically activate at 8am and continue until morning routine was complete.
The Guide was activated and data was recorded only on week days (Monday to Friday).
The voice used in Guide was female (CB) and familiar to Mr M. There were 12 datapoints in
the intervention period three weeks and some missing datapoints. Rehabilitation Support
Workers continued ratings in the Guide intervention (B) period Guide was in use. They were
asked to prompt if there was a safety critical error or omission of an important sub-step.
The Guide was inadvertently switched off after week 6 of the intervention leading to a de
facto return to baseline inpatient phase of four days (A0 three data points). Guide was then
reactivated and a second inpatient intervention phase of four weeks (B0211 data points)
took place.
Following agreement from the multidisciplinary team and community support agencies, Mr M
was discharged to his own home (29 June 2012). In this domestic situation the morning
routine performance was assessed using the morning checklist, completed by Mr M’s sister.
Rightful assertion of privacy and variable visiting times meant that direct observations were
not possible as in the rehabilitation centre.

The domestic install had a baseline of six data points and an intervention phase of 11 data
points. Findings are reported under in-patient and home headings.
Data analysis
The single case study data were analysed using the non-overlap all pairs (NAP) method
(Parker and Vannest, 2009; Parker et al., 2011). NAP represents a new application of
established statistical methods, known variously as area under the curve, Mann Whitney’s
U and dominance statistics, to single subject designs. NAP has been demonstrated to be
superior to other non-overlap techniques in its precision, discrimination and relationship to
established effect size measures such as R
2
(Parker and Vannest, 2009). An assumption of
the method is that there is no underlying trend in the baseline data. The Mann Kendall test of
trend (Onoz and Bayazit, 2003) was non-significant p.0.05 (two tailed) for the baseline
period. To further explore stability we also examined the regression equations for
the baseline data. A cubic equation had a higher R
2
(0.168) and accounted for more of the
variance than the linear model. This indicated that baseline scores fluctuated rather than
gradually improved. Parker and Vannest (2009) give approximate values for evaluating
effect sizes based on the NAP statistic: weak effects 0-0.65, medium effects 0.66-0.92, large
or strong effects 0.93-1.0.
Findings
In-patient
During the first intervention phase the morning checklist score was significantly increased in
comparison with baseline (NAP¼0.754). This represents a medium effect size (Parker and
Vannest, 2009). This indicates that the number of prompts given by support staff significantly
decreased in the first intervention phase. In the B0phase the participant approached perfect
performance (4.94/5.00).
The participant was rated to have completed all the steps without prompt only once in the
baseline period (3.6 percent) and completed the sequence independently six times out of
12 datapoints (50 percent) during the first intervention period. Visual presentation of these
changes in performance can be shown in Figure 1. Given the short duration of the return to
baseline phase (A0¼3 data points) comparisons-based solely on this data are likely to lack
statistical power. If however the inpatient data are combined, comparing all inpatient
intervention data (B þB0) to all inpatient control data (A þA0) gives a NAP statistic of 0.
804 (a medium effect size (Parker and Vannest, 2009)).

Sequence performance errors were significantly reduced during intervention phase
(Figure 2). The participant made on average 1.04 (standard deviation 1.23) errors in
baseline (A) and an average of 0 (SD ¼0) in the first intervention (B) phase. This indicates that,
for this participant, Guide use reduced errors to near zero. During the intervention period in the
rehabilitation centre, there did not appear to be a habituation effect such that performance
was constant throughout the intervention period, dipping only on return to baseline.
Home
This pattern of improvement was also apparent at home. The NAP (A00 2B00 )¼0.74, medium
effect size (Parker and Vannest, 2009) indicating a significant improvement in morning
checklist ratings from baseline and intervention conditions (A00 2B00). Figure1 shows both
in-patient and home prompt scores.
On returning home without Guide (A00) there was an increase in the error score to an average
of 1.67 (SD 1.75). This resolved once Guide was activated (average B00 ¼1.36 SD 0.67) but
error rates were not reduced to zero, at least in the first-ten days. This may have been an
artefact of difference in observers or due to the change of environment.
In the inpatient baseline phase (A) the participant made errors of: getting up and going
straight back to bed, hesitating during sequence, not being able to find clothes that are in the
room, and not getting all the clothes ready to be fully dressed. After discharge (A00) the more
frequent errors were: not getting all clothes to be fully dressed, wearing dirty or mismatched
clothes, forgetting to pick up phone/GPS and inappropriate clothes for the weather.
Personal preference. The mean rating of how the morning routine went was 4.5 in the
baseline phase and 4.33 in the intervention phase (non-significant). Both mean scores of
satisfaction lay in the range between ‘‘very well’ ’ and ‘‘quite well’’. Mr M did not have a clear
preference for either support. There was a slight anomaly in these findings as Mr M reported
not wishing to have rehabilitation support workers support him on several occasions.
Implications
The prompting technology, Guide, reduced the participants errors to near zero in the
intervention phase of the study and led to ratings of ‘‘independent’’ on half of intervention
trials. This trial thus evidences that Guide can emulate the supportive action of carers in the
performance of a complex ADL sequence.

The implications for practice of the use of this technology encompass the augmentation of
rehabilitation, facilitating discharge and home support. In terms of its use a rehabilitation
tool, Guide might augment the amount of prompting support for a specific routine without
increasing demands on staff. Rehabilitation support workers might then be freed to
address the emotional and motivational needs of those not-responding to automated
prompting.
Many service users object to being observed and prompted. The use of an automated,
non-judgemental and emotionally neutral prompter may be preferable to those who find the
interpersonal act of being prompted noxious (O’Neill and Gillespie, 2008; LoPresti et al.,
2004). Such technologies might therefore increase the user’s independence in ADL
sequences such as the morning routine.
The technology may aid in the transition from rehabilitation centre to home. For example,
if the person can carry out the sequence with prompting support, then Guide or a context
aware prompter may function as a cognitive prosthetic and allow that person to be
independent. Self-neglect is a common consequence of cognitive impairments. This
case study raises the intriguing possibility that tendency to omit personal care regimens
may be offset by context aware prompters.
Context aware prompting technologies are novel but are gaining an evidence base for their
effectiveness to support independent activity. There are no commercially available auditory
verbal context aware prompting systems.
There are limitations to the design reported. The participant was previously interested in
technologies and may have been more compliant as a result. He was also perhaps
motivated by a wish to be discharged to his own home.
Contemporary single nexperimental designs also include a variable which is not expected
to change in response to the intervention, omitted from this experimental design.
Increases in error rates and decreases in prompt score ratings of independence occurred
on return home and baseline. The transition to home was prepared for by many supported
visits and overnight passes. However, the emotional and cognitive demands of operating in
a new environment may have acted to increase errors.
Future studies might confirm these findings outside of the originating research group who
are currently recruiting for a randomised control trial due to report in 2014. Single nor case
control methodologies would be suitable and Guide software would be available to such
investigators.

... Prompting technologies are a class of ATC 1,12 that can increase independent activity in persons usually requiring carer input. 13 Prompting devices store information about actions to be carried out and provide timely cues. 14 They are divided into 2 functional classes: prospective prompting devices and micro-prompting devices. ...
... 32 Guide has previously been shown to be effective in supporting individuals to don prosthetic limbs 23 and in supporting the morning routine for an individual with history of intracerebral hemorrhage living at home. 13 The Guide system used had 4 components: (1) A Windows-enabled Dell Precision M4500 PC, Creative T10 speakers, and an Acoustic Magic Voice Tracker II directional microphone; (2) Dragon Naturally Speaking speech recognition software; (3) Guide activity protocols (created during the development and piloting phases); and (4) the Guide activity protocol player, that is, software that received the verbal responses, matched them to the protocol, and triggered the appropriate prompt. ...
... This adds to the evidence of the effectiveness of micro-prompting devices established in previous studies. 13,23 The study also demonstrates improvement in individuals with chronic neurobehavioral disability resulting from injuries sustained a number of years prior to the intervention, at which point biological recovery has traditionally been thought to have stabilized. This further extends the evidence that enhancing independence is possible and rehabilitation is effective in the long term after ABI. ...
Article
Objective: To evaluate the effectiveness of an automated interactive prompting technology in supporting the morning routine of persons with acquired brain injury. The morning routine included maintaining personal hygiene and dressing. Setting: An inpatient neurorehabilitation hospital. Participants: Persons with acquired brain injury who required prompting when following their morning routine (n = 24), but were not limited by physical disability or dysphasia, took part in the study. Participants (67% with traumatic brain injury) had impairment on indices of memory and executive function. Design: A randomized control trial evaluated the effect of an automated interactive micro-prompting device on the number of prompts by trained staff required for successful completion of the morning routine. Main measures: Study-specific checklists assessed sequence performance, errors, and verbal prompts required over baseline, rehabilitation as usual, intervention, and return to baseline conditions. Results: The intervention significantly reduced the support required to complete the task compared with usual rehabilitation. Conclusions: Micro-prompting technology is an effective assistive technology for cognition, which reduces support needs in people with significant cognitive impairments.
... Microprompting technologies such as GUIDE have been developed to guide people with executive impairment through tasks with multiple steps. O'Neill et al. [18] showed that technology could guide people with ABI to perform tasks they had difficulty with in both inpatient and community settings and showed that the GUIDE micro-prompting system could support people with their daily routine as effectively as intensive support from rehabilitation workers [19]. Some research has also explored the use of technology that can offer combined prompting and organization support [20]. ...
... One example of this is the GUIDE system that can deliver personalized prompts to help people with their morning routine. This system supports the individual to perform their morning routine with the same effectiveness as a human caregiver and removes the need for a carer to come into the service users room in the morning to deliver prompts, an action that can be perceived as intrusive [18]. ...

Background: Cognitive and behavioural difficulties after acquired brain injury (ABI) may lead to reduced engagement in leisure and social activities. Increasing participation is a goal of neuropsychological rehabilitation and assistive and behaviour change technology can play an important role in this. Focus groups and interviews were conductive with brain injury rehabilitation stakeholders (n = 24): people with ABI (n = 9), family members (n = 3) and care providers (n = 12) in order to understand the barriers to engaging in meaningful activities and what helps to overcome these barriers. A collaborative thematic analysis was performed by a multi-disciplinary research team using an approach based on Grounded Theory. Results: Four central, interlinked, barriers were found: Access, Cognitive Difficulties, Anticipation (of Physical or Cognitive Difficulties) and Motivation. To overcome these barriers, participants cited themes such as External Motivation from both Other People and Technology, Maintaining Momentum and different aspects of Being Planful. Conclusions: The results point to future directions for the purposeful development of effective assistive technology for this user group. Technology that is social, persuasive, adapts to individual needs and supports people to plan activities are likely to be particularly useful within neuropsychological rehabilitation. • Implications For Rehabilitation • Adults with ABI and their carers describe problems accessing activities, cognitive difficulties, anticipationof physical or cognitive difficulties and low motivation as the key barriers to undertaking meaningfulactivities. • Current solutions are external prompting, maintaining momentum and being planful. • This detailed qualitative analysis of a diverse group of carers and service users allows insight into theassistive technologies that could aid rehabilitation.
... Executive functioning is the term used to describe various cognitive abilities that underpin goal-directed behaviour, including initiating and planning actions, solving novel problems, correcting errors and selectively attending to relevant environmental stimuli (O'Neill et al., 2013). The study of executive functions has been linked to the operations of the frontal lobes. ...
... Microprompting technologies aim to guide people through a task with several substeps. An example of these technologies is the General User Interface for Disorders of Execution (GUIDE) voice-based prompting system that has been used to support people with executive impairment after vascular dementia to don prosthetic limbs, or to guide people with acquired brain injury (ABI) through their morning routine (O'Neill & Gillespie, 2008;O'Neill et al., 2013). Another example is COACH, an auditory and visual system designed to help guide people with dementia through hand washing (Mihailidis et al., 2000). ...
Chapter
This chapter discusses the influence of cognitive impairment in the prescription and effective use of electronic assistive technology (EAT). The authors consider the impact of cognitive, emotional and executive impairments on the use of EAT, and the effect of the course and prognosis of different types of neurodevelopmental versus acquired or progressive disorders. Self-awareness and motivation are also considered as key influences on the use and outcome of EAT. The effects of executive, attention and memory impairments on the ability to engage with technology and its implications for the uptake of EAT are explored, alongside strategies and technology developed to address these problems. The authors conclude the chapter by emphasising the importance of the development and improvement of affordable technologies with health applications. They highlight the usefulness of the neuro-socio-technical and technology acceptance models as a framework to adopt when prescribing EAT to people with cognitive impairments to fully consider the interplay between clinical presentation, social environmental factors and technological capabilities.
... 55 These positive findings were consistent with prior work. 56,57 Integrating alerting cues/reminders into a structured prospective memory training program improved the awareness of future tasks and strengthened functional outcomes. 58,59 The use of electronic reminder systems is supported as an external memory aid and combined with internal compensatory techniques to optimize compensation of memory impairments. ...

Introduction: Memory impairments affecting encoding, acquisition, and retrieval of information after moderate-to-severe traumatic brain injury (TBI) have debilitating and enduring functional consequences. The interventional research reviewed primarily focused on mild to severe memory impairments in episodic and prospective memory. As memory is a common focus of cognitive rehabilitation, clinicians should understand and use the latest evidence. Therefore, the INCOG ("International Cognitive") 2014 clinical practice guidelines were updated. Methods: An expert panel of clinicians/researchers reviewed evidence published since 2014 and developed updated recommendations for intervention for memory impairments post-TBI, a decision-making algorithm, and an audit tool for review of clinical practice. Results: The interventional research approaches for episodic and prospective memory from 2014 are synthesized into 8 recommendations (6 updated and 2 new). Six recommendations are based on level A evidence and 2 on level B. In summary, they include the efficacy of choosing individual or multiple internal compensatory strategies, which can be delivered in a structured or individualized program. Of the external compensatory strategies, which should be the primary strategy for severe memory impairment, electronic reminder systems such as smartphone technology are preferred, with technological advances increasing their viability over traditional systems. Furthermore, microprompting personal digital assistant technology is recommended to cue completion of complex tasks. Memory strategies should be taught using instruction that considers the individual's functional and contextual needs while constraining errors. Memory rehabilitation programs can be delivered in an individualized or mixed format using group instruction. Computer cognitive training should be conducted with therapist guidance. Limited evidence exists to suggest that acetylcholinesterase inhibitors improve memory, so trials should include measures to assess impact. The use of transcranial direct current stimulation (tDCS) is not recommended for memory rehabilitation. Conclusion: These recommendations for memory rehabilitation post-TBI reflect the current evidence and highlight the limitations of group instruction with heterogeneous populations of TBI. Further research is needed on the role of medications and tDCS to enhance memory.

Caregivers have traditionally provided assistance and care to patients with cognitive decline, but this has resulted in financial and emotional burdens for both caregivers and patients, impacting their quality of life. To address this issue, Ambient Assistive Living (AAL) technologies that incorporate Internet of Things (IoT) and Artificial Intelligence (AI) can replace or complement caregivers by enabling intelligent learning in smart buildings. This review evaluates the intelligence complements provided by smart buildings enabled with such capabilities to increase the quality of life and autonomy of cognitively declined occupants. Existing contributions primarily focus on learning occupants’ behavior to identify assistive services and solutions, which are delivered through technological interventions or caregivers. However, there are several key research gaps that need to be addressed. The most important is the lack of adequate implementation of technological interventions to fully support the occupants’ autonomy and independence. Other gaps include challenges in usability and acceptability, ethical concerns, systems’ comprehensiveness, and the need for human-in-the-loop. To address these gaps, a conceptual framework is proposed as future research directions for the applications of smart buildings supporting cognitively declined occupants. The framework aims to facilitate the implementation of technological interventions that can enhance occupants’ autonomy and independence, address usability and acceptability challenges, and ensure ethical considerations and system comprehensiveness. This review provides insights into the current state-of-the-art of AAL technologies and highlights research directions for improving the quality of life and autonomy of cognitively declined occupants.

Purpose The purpose of this paper is to review studies that evaluated technology-based prompting systems for supporting participants with dementia or acquired cognitive impairment in their performance of multistep daily tasks. Design/methodology/approach A scoping review was conducted to identify eligible studies through a search of four electronic databases, that is, PubMed, PsycINFO, Web of Science and Institute of Electrical and Electronics Engineers. Findings The search, which covered the 2010–2020 period, led to the identification of 1,311 articles, 30 of which were included in the review. These articles evaluated six different types of prompting systems: context-aware, automatic computer prompting, context-aware, mediated computer prompting, teleoperated robot prompting, self-operated augmented reality prompting, self-operated computer or tablet prompting and time-based (preset) computer, tablet or smartphone prompting. Originality/value Technology-aided prompting to help people with dementia or acquired cognitive impairment perform relevant multistep daily tasks is considered increasingly important. This review provides a picture of the different prompting options available and of their level of readiness for application in daily contexts.

Background and objectives: Smart home auto-prompting has the potential to increase the functional independence of persons with dementia (PWDs) and decrease caregiver burden as instrumental activities of daily living (IADLs) are completed at home. To improve prompting technologies, we sought to inductively understand how PWDs responded to auto-prompting while performing IADL tasks. Research design and methods: Fifteen PWDs completed eight IADLs in a smart home testbed and received a hierarchy of verbal auto-prompts (indirect, direct, multimodal) as needed for task completion. Two researchers viewed archived videos and recorded the observed behaviors of the PWDs and their reflections watching the PWDs. Using qualitative descriptive methods, an interdisciplinary analytic team reviewed transcripts and organized data into themes using content analysis. Results: Context and Communication emerged as the major themes, suggesting that positive user experiences will require auto-prompting systems to account for a multitude of contextual factors (individual and environmental) such as level of cognitive impairment, previous exposure to task, and familiarity of environment. Communicating with another human rather than an automated prompting system may be important if individuals begin to exhibit signs of stress while completing activities. Discussion and implications: Additional work is needed to create auto-prompting systems that provide specific, personalized, and flexible prompts. Holistic conceptualization of "successful task completion" is needed and a positive end-user experience will be key to utility. Such systems will benefit from including positive reinforcement, training, and exploration of how, and whether, direct human involvement can be minimized during the provision of in-home care.

The introduction of highly portable computers extends the range of tools potentially useful to persons with functional impairments of prospective memory resulting from brain injury. This study reviews the experience of 12 patients with brain injury undergoing outpatient treatment using palmtop computers to assist with memory dependent activities in their everyday lives. During the initial supervised trial period, each was provided a palmtop computer based memory aid capable of generating audible and visible reminder cues. Subsequently, patients were contacted for follow-up between 2 months and 4 years after initial trial usage, and surveyed as to the utility of the computer. Nine patients found palmtop computers were useful during supervised trials. Seven of nine patients actually continued to use such devices after the usage trials had ended. Experience with this technology has shown it to be useful in a high proportion of patients for assisting with memory dependent functions.

Objectives: To evaluate a paging system designed to improve independence in people with memory problems and executive deficits. Methods: After a successful pilot study, a randomised control trial was conducted involving a crossover design with 143 people aged between 8 and 83 years. All had one or more of the following: memory, planning, attention, or organisation problems. Most had sustained a traumatic head injury or a stroke although a few had developmental learning difficulties or other conditions. The crossover design ensured that some people received a pager after a 2 week baseline whereas others were required to wait for 7 weeks after the baseline before receiving the pager. Participants were assessed at three time periods-namely, at baseline, 7 weeks, and at 14 weeks postbaseline. Results: More than 80% of those who completed the 16 week trial were significantly more successful in carrying out everyday activities (such as self care, self medication, and keeping appointments) when using the pager in comparison with the baseline period. For most of these, significant improvement was maintained when they were monitored 7 weeks after returning the pager. Conclusions: This particular paging system significantly reduces everyday failures of memory and planning in people with brain injury.

Dementia reduces a person's ability to perform activities of daily living (ADL) because of the difficulty of remembering the proper sequence of events that must occur and how to use the required tools. The current solution is to have a caregiver continually provide verbal prompts. Family caregivers find assisting their loved ones to be particularly upsetting and embarrassing as it necessitates invasion of privacy and role reversal. It has been suggested that dependence on a caregiver might be improved using a cognitive orthosis that provides needed reminders and monitors progress. This paper will report on the results obtained from an efficacy study conducted with such a device.The COACH is a prototype of an intelligent computerised device that was developed to assist people with dementia complete ADLs with less dependence on a caregiver. The device was developed using a personal computer and a single video camera to unobtrusively track a user during an ADL and provided pre-recorded verbal prompts when necessary. It was tested with 10 subjects with moderate to severe dementia during handwashing in a study lasting 60 days. These trials showed that the number of handwashing steps that the subjects were able to complete without assistance from the caregiver increased overall by approximately 25% when the device was present. Individual changes ranged from approximately 10-45%. These changes were proven to be statistically significant at a 99% confidence level.

This paper is the first survey of the cognitive prosthetics field. Neurorehabilitation based on cognitive prosthetics is now reimbursed as a conventional therapy by many national insurance companies. The need for cognitive prosthetics is described in terms of gaps in rehabilitation methods, and a response to managed care limitations on duration of services. A definition is developed from work in the field, and a cognitive prosthesis is distinguished from both electronic aids as well as from conventional computer software. Some key concepts from computer science are reviewed, along with their significance to cognitive prosthetics. Key studies are reviewed, and show the accomplishments of researchers, differences in their orientation, as well as the impact of computer and communications advances over the past decade. There is a discussion of future research. A key problem is the need to make cognitive prosthetics rehabilitation more user friendly to the therapist. This will be necessary if cognitive prosthetics is to gain widespread use in rehabilitation facilities.

For close to 20 years, clinicians and researchers have been developing and assessing technological interventions for individuals with either acquired impairments or developmental disorders. This paper offers a comprehensive review of literature in that field, which we refer to collectively as assistive technology for cognition (ATC). ATC interventions address a range of functional activities requiring cognitive skills as diverse as complex attention, executive reasoning, prospective memory, self-monitoring for either the enhancement or inhibition of specific behaviours and sequential processing. ATC interventions have also been developed to address the needs of individuals with information processing impairments that may affect visual, auditory and language ability, or the understanding of social cues. The literature reviewed indicates that ATC interventions can increase the efficiency of traditional rehabilitation practices by enhancing a person's ability to engage in therapeutic tasks independently and by broadening the range of contexts in which those tasks can be exercised. More importantly, for many types of impairments, ATC interventions represent entirely new methods of treatment that can reinforce a person's residual intrinsic abilities, provide alternative means by which activities can be completed or provide extrinsic supports so that functional activities can be performed that might otherwise not be possible. Although the major focus of research in this field will continue to be the development of new ATC interventions, over the coming years it will also be critical for researchers, clinicians, and developers to examine the multi-system factors that affect usability over time, generalisability across home and community settings, and the impact of sustained, patterned technological interventions on recovery of function.
