    ABSTRACT: This special interest article provides a historical framework with a contemporary case example that traces the infusion of the science of motor learning into neurorehabilitation practice. The revolution in neuroscience provided the first evidence for learning-dependent neuroplasticity and presaged the role of motor learning as critical for restorative therapies after stroke. The scientific underpinnings of motor learning have continued to evolve from a dominance of cognitive or information processing perspectives to a blend with neural science and contemporary social-cognitive psychological science. Furthermore, advances in the science of behavior change have contributed insights into influences on sustainable and generalizable gains in motor skills and associated behaviors, including physical activity and other recovery-promoting habits. For neurorehabilitation, these insights have tremendous relevance for the therapist-patient interactions and relationships. We describe a principle-based intervention for neurorehabilitation termed the Accelerated Skill Acquisition Program that we developed. This approach emphasizes integration from a broad set of scientific lines of inquiry including the contemporary fields of motor learning, neuroscience, and the psychological science of behavior change. Three overlapping essential elements-skill acquisition, impairment mitigation, and motivational enhancements-are integrated.Video Abstract available (See Video, Supplemental Digital Content 1, http://links.lww.com/JNPT/A71) for more insights from the authors.

    ABSTRACT: Objective:To investigate the contributions of physiotherapy and occupational therapy to self-management interventions and the theoretical models used to support these interventions in chronic disease.Data sources:We conducted two literature searches to identify studies that evaluated self-management interventions involving physiotherapists and occupational therapists in MEDLINE, the Cochrane Library, CINAHL, EMBASE, AMED (Allied and Complementary Medicine), SPORTdiscus, and REHABDATA databases.Study selection:Four investigator pairs screened article title and abstract, then full text with inclusion criteria. Selected articles (n = 57) included adults who received a chronic disease self-management intervention, developed or delivered by a physiotherapist and/or an occupational therapist compared with a control group.Data extraction:Four pairs of investigators performed independent reviews of each article and data extraction included: (a) participant characteristics, (b) the self-management intervention, (c) the comparison intervention, (d) outcome measures, construct measured and results.Data synthesis:A total of 47 articles reported the involvement of physiotherapy in self-management compared with 10 occupational therapy articles. The type of chronic condition produced different yields: arthritis n = 21 articles; chronic obstructive pulmonary disease and chronic pain n = 9 articles each. The theoretical frameworks most frequently cited were social cognitive theory and self-efficacy theory. Physical activity was the predominant focus of the self-management interventions. Physiotherapy programmes included disease-specific education, fatigue, posture, and pain management, while occupational therapists concentrated on joint protection, fatigue, and stress management.Conclusions:Physiotherapists and occupational therapists make moderate contributions to self-management interventions. Most of these interventions are disease-specific and are most frequently based on the principles of behaviour change theories.

    ABSTRACT: PURPOSE:: To evaluate and compare the interrater reliability of the Motor Learning Strategy Rating Instrument (MLSRI) within usual and virtual reality (VR) interventions for children with acquired brain injury. METHODS:: Two intervention sessions for each of 11 children (total, 22) were videotaped; sessions were provided by 4 physical therapists. Videotapes were divided into usual and VR components and rated by 2 observers using the MLSRI. A generalizability theory approach was used to determine interrater reliability for each intervention. RESULTS:: Interrater reliability for usual interventions was high for the MLSRI total score (g-coefficient, 0.81), whereas it was low for the VR total score (g-coefficient, 0.28); MLSRI category g-coefficients varied from 0.35 to 0.65 for usual and from 0.17 to 0.72 for VR interventions. CONCLUSION:: Adequate reliability was achieved within ratings of usual interventions; however, challenges related to MLSRI use to rate VR-based interventions require further evaluation.

    ABSTRACT: To review the reporting of key design features in studies of stroke rehabilitation therapies. We used purposive sampling to examine English-language, human-subject, comparative studies focusing on stroke rehabilitation therapy provided the effect of therapy was evaluated in at least one of the following six outcome domains: ambulation, cognition, quality of life, daily activities, dysphagia, or communication. We searched MEDLINE®, CINAHL®, PsycINFO®, and the Cochrane Database of Systematic Reviews (date range: January 2000 through late-January 2008) and extracted data from included studies using standardized forms. We depicted the extracted data in tables and summarized the findings qualitatively in the text. We retrieved 1,674 citations in the literature search and extracted data from 99 studies. Authors' reporting of key design features in stroke rehabilitation studies was lacking in four areas, that is, the background of persons delivering therapy, timing of therapy, subjects' receipt of prior or concomitant treatment, and psychometric properties of outcome measurement instruments. Except for four areas, reporting of key design features in studies of stroke rehabilitation therapies was quite comprehensive. Researchers should pay particular attention to reporting blinding, and they should rationalize the number of outcome measurement instruments used in their studies.

    ABSTRACT: A "review of reviews" was undertaken to assess methodological issues in studies evaluating nondrug rehabilitation interventions in stroke patients. MEDLINE, CINAHL, PsycINFO, and the Cochrane Database of Systematic Reviews were searched from January 2000 to January 2008 within the stroke rehabilitation setting. Electronic searches were supplemented by reviews of reference lists and citations identified by experts. Eligible studies were systematic reviews; excluded citations were narrative reviews or reviews of reviews. Review characteristics and criteria for assessing methodological quality of primary studies within them were extracted. The search yielded 949 English-language citations. We included a final set of 38 systematic reviews. Cochrane reviews, which have a standardized methodology, were generally of higher methodological quality than non-Cochrane reviews. Most systematic reviews used standardized quality assessment criteria for primary studies, but not all were comprehensive. Reviews showed that primary studies had problems with randomization, allocation concealment, and blinding. Baseline comparability, adverse events, and co-intervention or contamination were not consistently assessed. Blinding of patients and providers was often not feasible and was not evaluated as a source of bias. The eligible systematic reviews identified important methodological flaws in the evaluated primary studies, suggesting the need for improvement of research methods and reporting.

    ABSTRACT: A goal of physical therapy interventions for children and youth with acquired brain injury (ABI) is the learning and relearning of motor skills. Therapists can apply theoretically derived and evidence-based motor learning strategies (MLSs) to structure the presentation of a task and organize the environment in ways that may promote effective, transfer-oriented practice. However, little is known about how MLSs are used in physical therapy interventions for children with ABI. The purpose of this study was to develop and validate an observer-rated Motor Learning Strategy Rating Instrument (MLSRI) quantifying the application of MLSs in physical therapy interventions for children with ABI. A multi-stage, iterative, item generation and reduction approach was used. An initial list of MLS items was generated through literature review. Seven experts participated in face validation to confirm item comprehensiveness. In a content validation process, 12 physical therapists with pediatric ABI experience responded to a questionnaire evaluating feasibility and importance of items. Six physical therapy sessions with clients with ABI were videotaped at a children's rehabilitation center. The 12 physical therapists participated in a session where they: (1) rated session videos to test the MLSRI and (2) provided verbal feedback. Revisions were made sequentially to the MLSRI based on these processes. The MLSRI was scored during videotape observation rather than being given a live rating, which may be onerous in certain settings and may influence therapist or child behavior. Further reliability investigations will determine whether the 33-item MLSRI is of help in documenting strategy use during intervention, as an evaluation tool in research, and as a knowledge transfer resource in clinical practice.

    ABSTRACT: Although task-oriented training has been shown to improve walking outcomes after stroke, it is not yet clear whether one task-oriented approach is superior to another. The purpose of this study is to compare the effectiveness of the Motor Learning Walking Program (MLWP), a varied overground walking task program consistent with key motor learning principles, to body-weight-supported treadmill training (BWSTT) in community-dwelling, ambulatory, adults within 1 year of stroke. A parallel, randomized controlled trial with stratification by baseline gait speed will be conducted. Allocation will be controlled by a central randomization service and participants will be allocated to the two active intervention groups (1:1) using a permuted block randomization process. Seventy participants will be assigned to one of two 15-session training programs. In MLWP, one physiotherapist will supervise practice of various overground walking tasks. Instructions, feedback, and guidance will be provided in a manner that facilitates self-evaluation and problem solving. In BWSTT, training will emphasize repetition of the normal gait cycle while supported over a treadmill, assisted by up to three physiotherapists. Outcomes will be assessed by a blinded assessor at baseline, post-intervention and at 2-month follow-up. The primary outcome will be post-intervention comfortable gait speed. Secondary outcomes include fast gait speed, walking endurance, balance self-efficacy, participation in community mobility, health-related quality of life, and goal attainment. Groups will be compared using analysis of covariance with baseline gait speed strata as the single covariate. Intention-to-treat analysis will be used. In order to direct clinicians, patients, and other health decision-makers, there is a need for a head-to-head comparison of different approaches to active, task-related walking training after stroke. We hypothesize that outcomes will be optimized through the application of a task-related training program that is consistent with key motor learning principles related to practice, guidance and feedback.

    ABSTRACT: Evidence that the physical environment is a fall risk factor in older adults is inconsistent. The study evaluated and summarised evidence of the physical environment as a fall risk factor. Eight databases (1985-2006) were searched. Investigators evaluated quality of two categories (cross-sectional and cohort) of studies, extracted and analysed data. Cross-sectional: falls occur in a variety of environments; gait aids were present in approximately 30% of falls. COHORT: Home hazards increased fall risk (odds ratio (OR) = 1.15; 95% confidence interval (CI): 0.97-1.36) although not significantly. When only the high quality studies were included, the OR = 1.38 (95% CI: 1.03-1.87), which was statistically significant. Use of mobility aids significantly increased fall risk in community (OR = 2.07; 95% CI: 1.59-2.71) and institutional (OR = 1.77; 95% CI: 1.66-1.89) settings. Home hazards appear to be a significant risk factor in older community-dwelling adults, although they may present the greatest risk for persons who fall repeatedly. Future research should examine relationships between mobility impairments, use of mobility aids and falls.

    ABSTRACT: To identify and describe the application of 3 motor learning strategies (verbal instructions, practice, and verbal feedback) within 4 intervention approaches (cognitive orientation to daily occupational performance, neuromotor task training, family-centered functional therapy, and activity-focused motor interventions). A scoping review of the literature was conducted. Two themes characterizing the application of motor learning strategies within the approaches are identified and described. Application of a motor learning strategy can be a defining component of the intervention or a means of enhancing generalization and transfer of learning beyond the intervention. Often, insufficient information limits full understanding of strategy application within the approach. A greater understanding of the application, and perceived nonapplication, of motor learning strategies within intervention approaches has important clinical and research implications.

    ABSTRACT: PURPOSE: The purpose of this article is to apply theoretical frameworks to adherence behaviour and to guide the development of an intervention to increase adherence to prescribed home programmes. SUMMARY OF KEY POINTS: Delivering an effective intervention requires establishing one that is evidence based and of adequate dosage. Two-thirds of patients who receive home exercise prescriptions do not adhere to their home programme, which may contribute to their physiotherapy's being ineffective. The mediating concepts of self-efficacy (SE) and outcome expectations (OE) are common to the five relevant theories used to explain adherence to exercise: the health belief model, protection motivation theory, theory of reasoned action, theory of planned behaviour, and social cognitive theory. CONCLUSION/RECOMMENDATIONS: Few intervention studies with any theoretical underpinning have examined adherence to exercise. Even fewer have been designed to affect and measure change in the theoretical mediators of SE and OE in patient populations. Physiotherapists must consider increasing adherence as a component of effective physiotherapy. Ongoing research is needed to increase our understanding of adherence to prescribed home programmes and to design interventions to affect theoretical mediators for increasing adherence.

    ABSTRACT: To determine the relationship between the amount of intra-individual variability in measures of abilities and participation throughout the first 8 months of recovery from ABI and outcome scores at 1 year. Greater amounts of intra-individual variability throughout recovery are hypothesized to predict better outcome scores at 1 year. This is a secondary data analysis of a longitudinal cohort study. Eighty-seven children and youths were assessed with self and proxy report measures of child functioning, family functioning and environmental factors at regular intervals after ABI. Mixed-effects modelling was used to determine individual linear recovery trajectories. Intra-individual variability was defined as the intra-individual standard deviation of the residuals around the recovery line. Less intra-individual variability in recovery predicts better outcomes of physical health (Child Health Questionnaire), behavioural functioning (Strengths and Difficulties Questionnaire), family coping (Impact on Family Scale) and impact of environmental barriers (Craig Hospital Inventory of Environmental Factors). As amount of intra-individual variability increases, outcomes become poorer. Findings support the existence of intra-individual variability in instrument scores over time in this sample and the impact of this variability on several outcomes at 1 year. Potential clinical and research implications are discussed.

    ABSTRACT: Children with developmental coordination disorder (DCD) are often identified by classroom teachers and the identification process relies heavily on teachers' perceptions. The literature would suggest that teachers' perceptions may be influenced by a child's gender, behaviour and the type of motor problem they demonstrate. To date, the influence of these factors on teachers' perceptions of children with DCD has not been empirically tested. This study investigated whether child gender, behaviour and type of motor problem influenced teachers' ratings of concern and importance of intervening for children with motor difficulties. One hundred and forty-seven teachers of children from 6 to 9 years of age participated in this study. Hypothetical case scenarios were developed that experimentally manipulated the factors of child gender (male/female), behaviour (disruptive/non-disruptive) and type of motor problem (fine motor/gross motor). Teachers were given two case scenarios of the same gender (that varied by behaviour) and rated: (a) their degree of concern about children's motor problems and (b) how important they thought it was for the child to receive intervention for that problem. The effect of child gender on teachers' perceptions depends upon the type of motor problem. While child behaviour had a marginal influence on teachers' perceptions, interestingly, teachers appeared to recognize motor problems only in the absence of disruptive behaviour. The type of motor problem demonstrated also influenced teachers' perceptions. This study provides preliminary insight into factors that influence teachers' perceptions of children with DCD with clear implications for the classroom identification of children with DCD.

    ABSTRACT: What value is there in effective practice regimes if these same regimes do not, in themselves, engage the learner to continue to practice? This question was discussed in the context of two practice schedules that have been shown to be effective in studies of motor learning. But recent evidence has found these practice schedules to be either inefficient in their use of practice time (distributed practice), or results in metacognitive judgments of incompetence (random practice). We discuss these conundrums, possible ramifications relative to the law of practice, and potential resolutions of these issues by recent research efforts.

    ABSTRACT: Following earlier work by Mechsner et al. (Nature 414 (2001) 69), the purpose of this experiment was to determine the perceptual and motoric contributions to bimanual coordination. Twenty right-handed, healthy, young adults performed continuous, horizontal, linear movements of both upper limbs at frequencies of 1.5 and 2.0 Hz. The goal was to control the spatial-temporal displacement of two flags by coordinating upper limb movements in two perceptual conditions. In a congruent condition, the movement of the flags matched the movement of the upper limbs. In an incongruent condition, the movement of the flags was opposite to the movement of the upper limbs. Measures of error in coordination provided support primarily for a motor view of bimanual coordination, and failed to replicate the earlier findings of Mechsner et al.

    ABSTRACT: This paper examines the results of a critical literature review describing the provision of education and functional training programs by occupational therapists with older adults to maximize their occupational performance. The critical review addressed the following question: What is the effectiveness of education and functional training programs in improving occupational performance and quality of life for older adults? Review methods are described and the outcomes of the critical review discussed. The results indicate that there is evidence that programs are effective in three areas: prevention of functional decline and falls, stroke and rheumatoid arthritis. Methodological limitations exist in some studies. There are several randomized controlled studies in this area, though the description of specific occupational therapy interventions is often vague and the programs could not be easily duplicated by occupational therapists. Occupational therapists are provided with information through this critical review to facilitate evidence-based practice when working with older adults.

    ABSTRACT: A temporary and/or involuntary stoppage of movement is identifiable in the execution phase of writing, walking, and turning movements in individuals with Parkinson's disease (PD) and may be referred to as freezing. However, the unpredictability of such akinetic impairments has made it difficult to study experimentally. The present study compared PD and age-matched control groups in their ability to coordinate continuous and simultaneous upper limb movements in trials involving two parts. In the first part of each trial, participants performed either in-phase movements (symmetric, simultaneous movement toward and away from the midline of the body), or anti-phase movements (isodirectional). At the midpoint of the trial, they were signaled by an auditory metronome to execute an intentional and voluntarily switch from the coordination currently being performed to the opposite coordination pattern. In the second half of the trial participants were required to maintain performance in the other coordination mode. All trials were paced by an auditory metronome at one of three different speeds (0.75, 1.25, 1.75 Hz). Measures of temporal coordination (relative phase) indicated that overall, participants with PD required significantly longer periods of time to achieve a switch between coordination patterns compared to healthy controls, and experienced greater difficulty changing from the in-phase to anti-phase mode of coordination. As well, movement stoppage was observed in 53.9% of the in-phase to anti-phase switch trials, but in only 15.5% of the anti-phase to in-phase trials. We conclude that interruptions to movement execution are most common when switching to coordinated movements that impose greater motor demands in individuals with PD.

    ABSTRACT: The purpose of this study was to investigate the effects of aging and the role of augmented visual information in the acquisition of a new bimanual coordination pattern, namely a 90 degrees relative phase pattern. In a pilot study, younger and older adults received augmented visual feedback in the form of a real-time orthogonal display of both limb movements after every fifth trial. Younger adults acquired this task over three days of practice and retained the task well over periods of one week and one month of no practice while the older adults showed no improvement at all on the task. It was hypothesized that the amount of augmented information was not sufficient for the older adults to overcome the strong tendency to perform natural, intrinsically stable coordination patterns, which consequently prevented them from learning the task. The present study evaluated the age-related role of augmented visual feedback for learning the new pattern. Participants were randomly assigned within age groups to receive either concurrent or terminal visual feedback after every trial in acquisition. In contrast to the pilot study, all of the older adults learned the pattern, although not to the same level as the younger adults. Both younger and older adults benefitted from concurrent visual feedback, but the older adults gained more from the concurrent feedback than the younger adults, relative to terminal feedback conditions. The results suggest that when learning bimanual coordination patterns, older adults are more sensitive to the structure of the practice conditions, particularly the availability of concurrent visual information. This greater sensitivity to the learning environment may reflect a diminished capacity for inhibitory control and a decreased ability to focus attention on the salient aspects of learning the task.

    ABSTRACT: Continuous coordinated movement of the upper limbs performed at different movement frequencies, and with different external timing conditions, was examined in individuals with Parkinson's disease (PD) and healthy, age- and gender-matched controls. Participants performed symmetric in-phase movements toward and away from the midline of the body, and isodirectional anti-phase movements at one of three metronome speeds (0.75, 1.25, and 1.75 Hz), and in two different auditory cueing conditions (cue present, cue absent). Measures of relative phase accuracy (absolute mean error) and stability (standard deviation) revealed that individuals with PD performed in-phase movements as well as the controls, while anti-phase movements were performed with greater mean error and variability. The adverse effects of PD on the anti-phase task were also reflected by freezing (8.1% of anti-phase trials) and hypometric deficits (5.1% of anti-phase trials) during movement. None of these PD-related impairments occurred during in-phase trials. The overall accuracy or stability of movement coordination was not improved with the presence of external pacing cues, suggesting that although execution impairments of individuals with PD may be dramatically influenced by attention, external cueing does not necessarily improve movement performance.
