Musical instrument classifier for early childhood percussion instruments.

While the musical instrument classification task is well-studied, there remains a gap in identifying non-pitched percussion instruments which have greater overlaps in frequency bands and variation in sound quality and play style than pitched instruments. In this paper, we present a musical instrument classifier for detecting tambourines, maracas and castanets, instruments that are often used in early childhood music education. We generated a dataset with diverse instruments (e.g., brand, materials, construction) played in different locations with varying background noise and play styles. We conducted sensitivity analyses to optimize feature selection, windowing time, and model selection. We deployed and evaluated our best model in a mixed reality music application with 12 families in a home setting. Our dataset was comprised of over 369,000 samples recorded in-lab and 35,361 samples recorded with families in a home setting. We observed the Light Gradient Boosting Machine (LGBM) model to perform best using an approximate 93 ms window with only 12 mel-frequency cepstral coefficients (MFCCs) and signal entropy. Our best LGBM model was observed to perform with over 84% accuracy across all three instrument families in-lab and over 73% accuracy when deployed to the home. To our knowledge, the dataset compiled of 369,000 samples of non-pitched instruments is first of its kind. This work also suggests that a low feature space is sufficient for the recognition of non-pitched instruments. Lastly, real-world deployment and testing of the algorithms created with participants of diverse physical and cognitive abilities was also an important contribution towards more inclusive design practices. This paper lays the technological groundwork for a mixed reality music application that can detect children's use of non-pitched, percussion instruments to support early childhood music education and play.

Evaluating the impact of movement tracking feedback on engagement with home exercise programmes of children with cerebral palsy using a new therapy app: a protocol for a mixed-methods single-case experimental design with alternating treatments.

INTRODUCTION: Children with cerebral palsy (CP) are prescribed home exercise programmes (HEPs) to increase the frequency of movement practice, yet adherence to HEPs can be low. This paper outlines the protocol for a single-case experimental design (SCED) with alternating treatments, using a new home therapy exercise application, Bootle Boot Camp (BBCamp), offered with and without movement tracking feedback. This study will explore the impact of feedback on engagement, movement quality, lower limb function and family experiences to help understand how technology-supported HEPs should be translated and the added value, if any, of movement tracking technology. METHODS AND ANALYSIS: In this explanatory sequential mixed-methods study using a SCED, 16 children with CP (aged 6-12 years, Gross Motor Function Classification System levels I-II) will set lower limb goals and be prescribed an individualised HEP by their physiotherapist to complete using BBCamp on their home television equipped with a three-dimensional camera-computer system. Children will complete four weekly exercise sessions over 6 weeks. Children will be randomised to 1 of 16 alternating treatment schedules where BBCamp will provide or withhold feedback during the first 4 weeks. The version of BBCamp that results in the most therapeutic benefit will be continued for 2 final weeks. Goals will be re-evaluated and families interviewed. The primary outcome is adherence (proportion of prescribed exercise repetitions attempted) as a measure of behavioural engagement. Secondary outcomes are affective and cognitive engagement (smiley face ratings), exercise fidelity, lower limb function, goal achievement and participant experiences. SCED data will be analysed using visual and statistical methods. Quantitative and qualitative data will be integrated using joint displays. ETHICS AND DISSEMINATION: Ethical approval was obtained from the Research Ethics Boards at Bloorview Research Institute and the University of Toronto. Results will be distributed through peer-reviewed journals and scientific conferences. TRIAL REGISTRATION NUMBER: NCT05998239; pre-results.

Measuring functional hand use in children with unilateral cerebral palsy using accelerometry and machine learning.

AIM: To investigate wearable sensors for measuring functional hand use in children with unilateral cerebral palsy (CP). METHOD: Dual wrist-worn accelerometry data were collected from three females and seven males with unilateral CP (mean age = 10 years 2 months [SD 3 years]) while performing hand tasks during video-recorded play sessions. Video observers labelled instances of functional and non-functional hand use. Machine learning was compared to the conventional activity count approach for identifying unilateral hand movements as functional or non-functional. Correlation and agreement analyses compared the functional usage metrics derived from each method. RESULTS: The best-performing machine learning approach had high precision and recall when trained on an individual basis (F1 = 0.896 [SD 0.043]). On an individual basis, the best-performing classifier showed a significant correlation (r = 0.990, p < 0.001) and strong agreement (bias = 0.57%, 95% confidence interval = -4.98 to 6.13) with video observations. When validated in a leave-one-subject-out scenario, performance decreased significantly (F1 = 0.584 [SD 0.076]). The activity count approach failed to detect significant differences in non-functional or functional hand activity and showed no significant correlation or agreement with the video observations. INTERPRETATION: With further development, wearable accelerometry combined with machine learning may enable quantitative monitoring of everyday functional hand use in children with unilateral CP.

Development of the Preferred Components for Co-Design in Research Guideline and Checklist: Protocol for a Scoping Review and a Modified Delphi Process.

BACKGROUND: There is increasing evidence that co-design can lead to more engaging, acceptable, relevant, feasible, and even effective interventions. However, no guidance is provided on the specific designs and associated methods or methodologies involved in the process. We propose the development of the Preferred Components for Co-design in Research (PRECISE) guideline to enhance the consistency, transparency, and quality of reporting co-design studies used to develop complex health interventions. OBJECTIVE: The aim is to develop the first iteration of the PRECISE guideline. The purpose of the PRECISE guideline is to improve the consistency, transparency, and quality of reporting on studies that use co-design to develop complex health interventions. METHODS: The aim will be achieved by addressing the following objectives: to review and synthesize the literature on the models, theories, and frameworks used in the co-design of complex health interventions to identify their common elements (components, values or principles, associated methods and methodologies, and outcomes); and by using the results of the scoping review, prioritize the co-design components, values or principles, associated methods and methodologies, and outcomes to be included in the PRECISE guideline. RESULTS: The project has been funded by the Canadian Institutes of Health Research. CONCLUSIONS: The collective results of this project will lead to a ready-to-implement PRECISE guideline that outlines a minimum set of items to include when reporting the co-design of complex health interventions. The PRECISE guideline will improve the consistency, transparency, and quality of reports of studies. Additionally, it will include guidance on how to enact or enable the values or principles of co-design for meaningful and collaborative solutions (interventions). PRECISE might also be used by peer reviewers and editors to improve the review of manuscripts involving co-design. Ultimately, the PRECISE guideline will facilitate more efficient use of new results about complex health intervention development and bring better returns on research investments.

Understanding a videogame home intervention for children with hemiplegia: a mixed methods multi-case study.

Introduction: Access to rehabilitation therapies is a salient and growing issue for children with cerebral palsy (CP) and their families, motivating interest in home-based interventions. Bootle Blast is a low-cost, movement-tracking videogame that can be used at home to encourage upper limb (UL) functional exercise tailored to each child's abilities and therapy goals. The study objectives were to: 1) Establish the extent to which children achieve their self-directed play-time goal over a 12-week intervention, 2) Measure changes in UL motor outcomes, and 3) Explore participants' experiences of using Bootle Blast at home. Methods: Mixed methods case series study of four children with hemiplegic cerebral palsy (HCP), each with a participating parent. Participants played Bootle Blast at home for 12 weeks. Study assessments occurred at baseline, post-intervention and four week follow up. A post-intervention interview explored participants' experiences. Game-logs provided play time and progress data. Results: Three of four participants (8-13 yrs., Manual Ability Classification Level I-II) completed the intervention. One dropped out at week 6. Play-time goals were achieved in most weeks, with two of four children surpassing their overall intervention goals. Outcomes varied across the three participants, however consistent improvements were observed on the Canadian Occupational Performance Measure and the Box and Blocks Test. Inductive analysis generated four main themes: 1) Intrinsic motivators fostered play engagement, 2) Virtual play for real-world gains, 3) Therapy on demand (at home), and 4) Shifting the onus from the parent to the game. Integration of qualitative and quantitative data was important for interpreting play patterns/usage and clinical outcomes. Discussion: This mixed methods study describes a novel videogaming intervention designed for home-rehabilitation for children with HCP and provides preliminary evidence to guide future study design and research. Clinical Trial Registration: [https://clinicaltrials.gov/ct2/show/NCT04009031?recrs=h&cond=Cerebral+Palsy&cntry=CA&city=Toronto&draw=2&rank=1], identifier [NCT04009031].

Multi-domain assessment of sports-related and military concussion recovery: A scoping review.

OBJECTIVE: This review explores the literature on multi-domain assessments used in concussion recovery, to inform evidence-based and ecologically valid return-to-play. It asks: What simultaneous, dynamic multi-domain paradigms are used to assess recovery of youth and adults following concussion? METHODS: Five databases were searched (CINAHL, EMBASE, MEDLINE, PsycInfo, SPORTDiscus) until September 30, 2021. Records were limited to those published in peer-reviewed journals, in English, between 2002 and 2021. Included studies were required to describe the assessment of concussion recovery using dynamic paradigms (i.e., requiring sport-like coordination) spanning multiple domains (i.e., physical, cognitive, socio-emotional functioning) simultaneously. RESULTS: 7098 unique articles were identified. 64 were included for analysis, describing 36 unique assessments of 1938 concussed participants. These assessments were deconstructed into their constituent tasks: 13 physical, 17 cognitive, and one socio-emotional. Combinations of these "building blocks" formed the multi-domain assessments. Forty-six studies implemented level walking with a concurrent cognitive task. The most frequently implemented cognitive tasks were 'Q&A' paradigms requiring participants to answer questions aloud during a physical task. CONCLUSIONS: A preference emerged for dual-task assessments, specifically combinations of level walking and Q&A tasks. Future research should balance ecological validity and clinical feasibility in multi-domain assessments, and work to validate these assessments for practice.

R2Play development: Fostering user-driven technology that supports return-to-play decision-making following pediatric concussion.

Objective: To design a multi-domain return-to-play assessment system (R2Play) for youth athletes with concussion. Methods: The R2Play system was developed using an overarching user-centered approach, the Design Thinking Framework, and research activities included: 1) structured brainstorming within our research team, 2) interviews with clinician and youth sports coaches, 3) building a testable prototype, and 4) interface testing through cognitive walkthroughs with clinician partners. Results: Clinician and coach participants provided feedback on the R2Play concept, which was integrated into the design process and provided future directions for research. Examples of feedback-driven design choices included reducing assessment time, increasing ecological validity by adding in background noise, and developing youth-friendly graphical results screens. Following refinement based on stakeholder feedback, the R2Play system was outlined in detail and a testable prototype was developed. It is made up of two parts: a clinician tablet, and a series of tablet "buttons" that display numbers and letters. Youth athletes run between the buttons to connect a "trail" in ascending alphanumeric order, 1-A-2-B, etc. Their performance across a series of levels of increasing difficulty is logged on the clinician tablet. Initial testing with five clinicians showed the system's interface to have excellent usability with a score of 81% (SD = 8.02) on the System Usability Scale. Conclusion: Through this research, a prototype of the R2Play system was innovated and evaluated by clinician and coach stakeholders. Initial usability was excellent and directions for future iterations were highlighted. Outcomes suggest the potential benefits of using technologies to assist in complex clinical assessment, as well as utilizing a user-centered approach to design.

Clinician perspectives on the implementation of inpatient cycling-based exergames for children with cerebral palsy: A qualitative study.

OBJECTIVE: To understand the perspectives of key stakeholder clinicians in implementing inpatient cycling-based exergames for children with cerebral palsy (CP) into pediatric rehabilitation. METHODS: Sixteen clinicians (nurses, physiotherapists, recreational therapists) that participated in a study exploring the feasibility of implementing cycling-based exergames for inpatient children with CP were interviewed. Clinicians' responses were coded using the Theoretical Domains Framework (TDF). Beliefs were generated from each response and relevant domains were identified. RESULTS: Ten domains from the TDF were identified as relevant. Key enablers to clinician participation in future implementation included revision of clinician roles and responsibilities, the belief that children with CP will benefit from exergames, and the belief in potential applicability to other pediatric populations. Barriers included clinician limited time and exergame responsibilities not aligning with perceived clinician roles. CONCLUSIONS: This study identifies key barriers and enablers that future inpatient pediatric rehabilitation settings should consider when incorporating exergames into rehabilitation practice.

Characterizing Changes in Screen Time During the COVID-19 Pandemic School Closures in Canada and Its Perceived Impact on Children With Autism Spectrum Disorder.

The COVID-19 pandemic has led to an increase in screen time for children and families. Traditionally, screen time has been associated with negative physical and mental health outcomes, and children with autism spectrum disorder (ASD) are at increased risk of these outcomes. The primary objectives of this study were to (1) characterize the change in screen time during COVID-19 school closures for children with ASD, and (2) examine the parent perceived impact of screen time on mental health and quality of life of children and their families. Canadian parents and caregivers of children 19 years of age and younger were eligible to participate in an anonymous, online survey study. This survey was available in English, consisted of 28 questions, took ~10-min to complete, and was available for 6 weeks (May 22 through July 6, 2020). The total sample consisted of 414 responses (ASD: n = 127, mean age = 11.7 ± 4.06 years; community sample: n = 287, mean age = 9.4 ± 4.26 years). Seventy-one respondents were missing responses to our primary question and removed from the analyses (final sample n = 344). Compared to the community sample, the ASD group had a significantly higher screen time use before and during the COVID-19 pandemic school closures [weekdays: difference = 1.14 (SE = 0.18), t = 6.56, p < 0.0001; weekends: difference = 1.41 (SE = 0.20), t = 6.93, p < 0.0001]. Mean total screen time during the pandemic was 6.9 h (95% CI 6.49, 7.21) on weekdays and 6.3 h (95% CI 5.91, 6.63) on weekends for the ASD group, and 5.6 h (95% CI 5.28, 5.92) on weekdays and 5.0 h (95% CI 4.70, 5.34) on weekends for the community sample. There was a significant increase in screen time during the COVID-19 pandemic as compared to before the pandemic period in the ASD group [weekdays: mean difference = 3.8 h (95% CI 3.35-4.25), p < 0.0001; weekends: mean difference = 1.5 h (95% CI 1.17-1.92), p < 0.0001]. Gender was a significant predictor of parent perceived mental health and quality of life, with male gender associated with a higher likelihood of negative impact [quality of life (child/family) OR = 1.8 (95% CI 1.1-2.9), corrected p = 0.040; mental health OR = 1.9 (95% CI 1.1-3.1), corrected p = 0.0028]. Parents' most frequently endorsed emotions toward screen time were guilt, frustration, and worry. Results of this survey study revealed that children with ASD were less likely to benefit from screen time to cope with social isolation, and screen time resulted in significantly more lost time on social interactions than the community sample, which may exacerbate difficulties in social domains. Given the unprecedented circumstances of the COVID-19 pandemic and the novel context of technology use, the findings of this study highlight the need for revision of screen time recommendations to reflect the current needs of children and families.

Engaging children with cerebral palsy in interactive computer play-based motor therapies: theoretical perspectives.

PURPOSE: To provide a theoretically grounded understanding of engagement in interactive computer play-based motor therapies by children with cerebral palsy in home settings. METHODS: A motivational framework for engagement and its relationship with three contemporary theories (self-determination theory, expectancy-value theory, social cognitive theory of self-regulation) was overviewed. A scoping review was conducted to understand how engagement is influenced by features of the technology and intervention design that impact intrinsic and extrinsic motivation, child and parent values and expectancies, and the processes of self-regulation. Multiple reviewers screened and extracted data from 26 articles describing home-based clinical trials of interactive computer play-based motor interventions for children with cerebral palsy. A narrative synthesis framework was used for analysis. RESULTS: Features of the technology and the intervention influence feelings of autonomy (e.g., personalization), competence (e.g., calibration), and relatedness (e.g., social play, virtual therapist/coach). There may be multiple and differently valued goals in interactive computer play-based interventions (e.g., game- and therapy-focused) that, if disconnected or unmet, negatively impact engagement. Multiplayer interactions, real-time feedback and progress tracking provide information that influences self-regulation and engagement over time. CONCLUSIONS: Optimizing engagement in interactive computer play-based motor interventions requires closer alignment with client-led values/goals; design of technologies and interventions that sustain intrinsic motivation; and feedback that informs/builds self-efficacy. Implications for rehabilitation The decision to prescribe an interactive computer play-based motor intervention should be guided by client-led goals and an informed understanding of the capacity of the interactive computer play-based intervention to meet individual client values/expectancies. Sustaining intrinsic motivation in interactive computer play-based motor therapies is greatly influenced by features of the technology (e.g., calibration, feedback, personalization) and the intervention (e.g., interactions with therapists, social play). Increased effort should be directed towards ensuring that interactive computer play-based interventions and technologies reward and reinforce efforts towards therapy goals.

A Classification and Calibration Procedure for Gesture Specific Home-Based Therapy Exercise in Young People With Cerebral Palsy.

Movement-based video games can provide engaging practice for repetitive therapeutic gestures towards improving manual ability in youth with cerebral palsy (CP). However, home-based gesture calibration and classification is needed to personalize therapy and ensure an optimal challenge point. Nineteen youth with CP controlled a video game during a 4-week home-based intervention using therapeutic hand gestures detected via electromyography and inertial sensors. The in-game calibration and classification procedure selects the most discriminating, person-specific features using random forest classification. Then, a support vector machine is trained with this feature subset for in-game interaction. The procedure uses features intended to be sensitive to signs of CP and leverages directional statistics to characterize muscle activity around the forearm. Home-based calibration showed good agreement with video verified ground truths (0.86 ± 0.11, 95%CI = 0.93-0.97). Across participants, classifier performance (F1-score) for the primary therapeutic gesture was 0.90 ± 0.05 (95%CI = 0.87-0.92) and, for the secondary gesture, 0.82 ± 0.09 (95%CI = 0.77-0.86). Features sensitive to signs of CP were significant contributors to classification and correlated to wrist extension improvement and increased practice time. This study contributes insights for classifying gestures in people with CP and demonstrates a new gesture controller to facilitate home-based therapy gaming.

A biofeedback-enhanced therapeutic exercise video game intervention for young people with cerebral palsy: A randomized single-case experimental design feasibility study.

IMPORTANCE/BACKGROUND: Movement-controlled video games have potential to promote home-based practice of therapy activities. The success of therapy gaming interventions depends on the quality of the technology used and the presence of effective support structures. AIM: This study assesses the feasibility of a novel intervention that combines a co-created gaming technology integrating evidence-based biofeedback and solution-focused coaching (SFC) strategies to support therapy engagement and efficacy at home. METHODS: Following feasibility and single-case reporting standards (CONSORT and SCRIBE), this was a non-blind, randomized, multiple-baseline, AB, design. Nineteen (19) young people with cerebral palsy (8-18 years old) completed the 4-week home-based intervention in France and Canada. Participant motivations, personalized practice goals, and relevance of the intervention to daily activities were discussed in a Solution Focused Coaching-style conversation pre-, post-intervention and during weekly check-ins. Participants controlled a video game by completing therapeutic gestures (wrist extension, pinching) detected via electromyography and inertial sensors on the forearm (Myo Armband and custom software). Process feasibility success criteria for recruitment response, completion and adherence rates, and frequency of technical issues were established a priori. Scientific feasibility, effect size estimates and variance were determined for Body Function outcome measures: active wrist extension, grip strength and Box and Blocks Test; and for Activities and Participation measures: Assisting Hand Assessment (AHA), Canadian Occupational Performance Measure (COPM) and Self-Reported Experiences of Activity Settings (SEAS). RESULTS: Recruitment response (31%) and assessment completion (84%) rates were good and 74% of participants reached self-identified practice goals. As 17% of technical issues required external support to resolve, the intervention was graded as feasible with modifications. No adverse events were reported. Moderate effects were observed in Body Function measures (active wrist extension: SMD = 1.82, 95%CI = 0.85-2.78; Grip Strength: SMD = 0.63, 95%CI = 0.65-1.91; Box and Blocks: Hedge's g = 0.58, 95%CI = -0.11-1.27) and small-moderate effects in Activities and Participation measures (AHA: Hedge's g = 0.29, 95%CI = -0.39-0.97, COPM: r = 0.60, 95%CI = 0.13-0.82, SEAS: r = 0.24, 95%CI = -0.25-0.61). CONCLUSION: A definitive RCT to investigate the effectiveness of this novel intervention is warranted. Combining SFC-style coaching with high-quality biofeedback may positively engage youth in home rehabilitation to complement traditional therapy. TRIAL REGISTRATION: ClinicalTrials.gov, U.S. National Library of Medicine: NCT03677193.

Children and Teens in Charge of their Health (CATCH): A protocol for a feasibility randomised controlled trial of solution-focused coaching to foster healthy lifestyles in childhood disability.

INTRODUCTION: Children with physical disabilities are rarely included in interventions to promote healthy lifestyles, despite being at higher risk for suboptimal dietary and physical activity behaviours. The Children and Teens in Charge of their Health study explores the feasibility and acceptability of conducting a randomised controlled trial (RCT) of a strengths-based, solution-focused coaching intervention for improving and sustaining physical activity and healthy dietary habits in children and young people with physical disabilities. METHODS AND ANALYSIS: Thirty children aged 10-18 years with a diagnosis of spina bifida or cerebral palsy who are able to set healthy lifestyle goals will be recruited from two children's rehabilitation hospitals in Ontario, Canada. Participants will be enrolled in the study for twelve months. All participants will receive standard care and printed information about healthy lifestyles. Of the 30 participants, 15 will be randomised to receive a coaching intervention for the first 6 months. Health indicators and psychosocial outcomes will be assessed by blinded assessors four times: at the start of the trial, immediately postintervention (6 months after randomisation), and at 3 and 6 months postintervention (9 and 12 months after randomisation, respectively). Predefined success criteria will be used to assess the feasibility of trial processes such as recruitment, attrition, stratification and intervention fidelity. Acceptability and perceived impact of the intervention will be explored qualitatively. ETHICS AND DISSEMINATION: The study has been approved by Holland Bloorview Kids Rehabilitation Hospital's Research Ethics Board (Ref: 17-752). A knowledge translation planning template will be used to ensure our findings have maximum reach. TRIAL REGISTRATION NUMBER: NCT03523806.

Biofeedback interventions for individuals with cerebral palsy: a systematic review.

Purpose: The purpose of this study is to evaluate the quality of evidence of biofeedback interventions aimed at improving motor activities in people with Cerebral Palsy (CP). Second, to describe the relationship between intervention outcomes and biofeedback characteristics. Methods: Eight databases were searched for rehabilitation interventions that provided external feedback and addressed motor activities. Two reviewers independently assessed and extracted data. The Grading of Recommendations Assessment, Development, and Evaluation (GRADE) framework was used to evaluate quality of evidence for outcome measures related to two International Classification of Functioning, Disability and Health (ICF) chapters. Results: Fifty-seven studies were included. There were 53 measures related Activities and Participation and 39 measures related to Body Functions. Strength of evidence was "Positive, Very-Low" due to the high proportion of non-controlled studies and heterogeneity of measures. Overall, 79% of studies and 63% of measures showed improvement post-intervention. Counter to motor learning theory recommendations, most studies provided feedback consistently and concurrently throughout the intervention regardless of the individual's desire or progress. Conclusion: Heterogeneous interventions and poor study design limit the strength of biofeedback evidence. A thoughtful biofeedback paradigm and standardized outcome toolbox can strengthen the confidence in the effect of biofeedback interventions for improving motor rehabilitation for people with CP. Implications for Rehabilitation Biofeedback can improve motor outcomes for people with Cerebral Palsy. If given too frequently, biofeedback may prevent the client from learning autonomously. Use consistent and concurrent feedback to improve simple/specific motor activities. Use terminal feedback and client-directed feedback to improve more complex/general motor activities.

Positive Distraction in Pediatric Healthcare Waiting Spaces: Sharing Play Not Germs through Inclusive, Hands-Free Interactive Media.

Purpose: To investigate the value of shared opportunities for positive distraction in pediatric healthcare environments. Methods: Self-selected activities of 271 young people (5-19 years) with diverse neurodevelopmental conditions were observed in an ambulatory pediatric rehabilitation clinic. Shared opportunities included hands-free media (nature video or interactive media) and an aquarium. Anxiety was self-reported on the State Trait Anxiety Scale upon arrival and after 10 minutes in the waiting space. Results: Young people engaged more with shared opportunities for distraction (n = 170/271) than personal items brought from home (n = 119/271), p = 0.02. Personal electronic devices were used by 67 young people, but did not positively impact anxiety. Interactive media and the aquarium significantly reduced anxiety (p < 0.04) while the nature video appeared to increase anxiety (p = 0.036). Age influenced activity preference and anxiety. Shared, hands-free interactive media engaged individuals of diverse age and mobility. Conclusion: Shared opportunities for positive distraction in healthcare facilities are valuable, particularly hands-free interactive media.

Force Resistance Training in Hand Grasp and Arm Therapy: Feasibility of a Low-Cost Videogame Controller.

OBJECTIVE: To design and evaluate a low-cost gaming station that supports force resistance training in pediatric arm/hand grasp therapies through mainstream videogame play. METHODS: The gaming station was developed through an iterative participatory design process and includes a force feedback game controller (Novint Falcon), custom grips, arm/wrist supports, and software to interface with mainstream games and manage difficulty settings in the controller. The station was tested for usability and feasibility with six therapists and six children with cerebral palsy, 7-16 years of age, attending weekly therapy sessions over 12 weeks. Pre- and post-assessments of perceived performance and satisfaction on self-identified goals were measured on the Canadian Occupational Performance Measure (COPM). RESULTS: The gaming station was considered highly usable by therapists with a score of 76.7 (standard deviation [SD] = 6.1) on the System Usability Scale. Overall, children enjoyed the games, achieved high repetition rates for wrist extensions and arm movements, and all made clinically significant progress on therapy goals. Increases of 3.13 (SD = 1.69) on the performance scale and 2.97 (SD = 0.98) on the satisfaction scale were reported on the COPM. Conclusiion: In-clinic force resistance training for development of upper limb functional capacities is feasible using low-cost video game components adapted to therapy through a participatory design process.

Interactive media as a tool for reducing waiting anxiety at paediatric rehabilitation hospitals: a randomized controlled trial.

AIM: To investigate the efficacy of waiting room media for reducing anxiety and increasing satisfaction at a paediatric rehabilitation hospital. METHOD: In this clustered, parallel, randomized controlled trial, 310 young people with disabilities (age range 5-19y) and their parents attending outpatient clinics were assigned to interactive media (n=113), a silent nature video (n=97), or media-free comparison (n=100) groups. Young person and parent anxiety was reported using the State-Trait Anxiety Inventory (STAI) on arrival and after 10 minutes in the waiting space. Questionnaires measured young person, parent, and staff satisfaction. RESULTS: Young people exposed to interactive media reported a postexposure state anxiety that was 1.1 raw points (2.7 standardized points) lower on the STAI than the comparison group (95% confidence interval [CI] -1.9 to -0.22). There was no difference in postexposure state anxiety between the passive media and comparison groups (95% CI -0.64 to 1.1). Parents' state anxiety did not differ between conditions, but interactive media were associated with greater satisfaction (p=0.009). Of 120 staff, 119 reported that interactive media improved the clinic experience for families. INTERPRETATION: Interactive media designed for accessible, hands-free play mitigate waiting anxiety and increases satisfaction. This paper provides evidence to guide design and decision-making around the use of interactive media in health care spaces. WHAT THIS PAPER ADDS: Interactive media reduced preclinic waiting anxiety for young people with disabilities. Interactive media were accessible to young people with a range of mobility. Interactive media increased parental and staff satisfaction in the clinic. Guidelines for the design of hands-free, inclusive interactive media for health care facilities are presented.

A feasibility study using solution-focused coaching for health promotion in children and young people with Duchenne muscular dystrophy.

PURPOSE: To evaluate the feasibility and acceptability of a coaching intervention (Solution-Focused Coaching in pediatric rehabilitation [SFC-Peds]) related to physical activity and diet in males with Duchenne muscular dystrophy. METHODS: A pre-post design was employed. Participants had five coaching sessions over 8 weeks. The first session was face-to-face, followed by four virtual sessions. Feasibility criteria included recruitment rates, attrition, and intervention fidelity. The Canadian Occupational Performance Measure (COPM) and Goal Attainment Scaling (GAS) were employed to look at outcome trends. The acceptability was assessed using a survey. RESULTS: Five males (11-19 years) participated. All feasibility criteria were met. Clinically significant increases were observed for GAS and COPM scores. Participants reported SFC-Peds to be acceptable. Broad barriers and facilitators to coaching success were identified. CONCLUSIONS: A SFC-Peds intervention for health promotion is feasible and acceptable in children with DMD and their families. A rigorous efficacy study assessing SFC-Peds intervention is warranted.

"It's all about incentive": Social technology as a potential facilitator for self-determined physical activity participation for young people with physical disabilities.

PURPOSE: To investigate the perceived role of social technologies in promoting physical activity participation for young people with physical disabilities and to identify design considerations that should be addressed when creating social technologies to promote physical activity. METHOD: Interactive design workshops for young people with physical disabilities aged 12-18 (n = 8) were held. Data were analyzed using interpretive thematic analysis. RESULTS: Young people perceived significant benefit for social technologies to promote physical activity as they have the potential to overcome many barriers to physical activity participation. Design features recommended by the participants included (1) options for diverse interests and preferences, (2) provision of informational support, (3) support through equitable technology design, (4) incentive through competition and play, and (5) opportunities to develop community. CONCLUSIONS: Social technology has potential to provide tailored, equitable opportunities for social engagement and physical activity participation for young people with physical disabilities through needs- and preference-specific design.

Biofeedback interventions for people with cerebral palsy: a systematic review protocol.

BACKGROUND: Cerebral palsy is a life-long disability that affects motor control and activities of daily living. Depending on the type of cerebral palsy, some individuals may have trouble performing tasks with one or both of their arms and/or legs. Different strategies exist to help develop motor capacity. Biofeedback therapy is a commonly applied rehabilitation strategy. In biofeedback therapy, information about the motor behavior while completing a task is given back to the individual to help improve their performance. This can provide valuable information that would otherwise be unknown to the individual. Biofeedback may also have a unique method of operation in clinical populations, such as people with cerebral palsy. Therefore, it is important to identify the most effective mechanisms for specific populations. This review aims to evaluate the effects of biofeedback interventions that have been used towards improving motor performance and motor learning in people with cerebral palsy. METHODS: Using a customized strategy, MEDLINE, CINAHL, Embase, PsycINFO, Cochrane Central Register of Controlled Trials, SCOPUS, SPORTDiscus, and PEDro databases will be searched. Two independent reviewers will screen titles and abstracts, review full texts for inclusion criteria, and extract data from relevant articles using a standardized template. Quality of evidence and risk of bias will be assessed through the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) methodology.
