Virtual Reality and Active Video Game Integration within an Intensive Bimanual Therapy Program for Children with Hemiplegia.

AIMS: To describe the nature of custom and non-custom virtual reality and active video game (VR/AVG) implementation within a Hand-Arm Bimanual Intensive Therapy Including Lower Extremities (HABIT-ILE) intervention program for children with hemiplegia. METHODS: Six children aged 8-11 years participated in a 10-day HABIT-ILE intervention (65 h; 6.5 planned VR/AVG hours). VR/AVG implementation details were recorded daily and summarized with descriptive statistics; active motor engagement was quantified as minutes of active game participation. Post-intervention interviews with interventionists were analyzed with qualitative content analysis. RESULTS: On average, participants received 79% of the planned VR/AVG dosage (314/400 planned minutes, range 214-400 min), of which the per-session active motor engagement average was 68% (27 min, SD 12 min). Participation involved equivalent amounts of custom (49%) and non-custom (51%) VR/AVG system use. Material and verbal adaptations facilitated alignment with HABIT-ILE principles. Interventionists identified type of task (gross versus fine motor), children's perceived motivation, and VR/AVG attributes as factors influencing active motor engagement and alignment with HABIT-ILE principles. CONCLUSIONS: Describing individual and technological challenges of VR/AVG integration within HABIT-ILE can advance knowledge about VR/AVG use in intensive interventions and identify directions for subsequent research.

Cognitive behavioral therapies for individuals with cerebral palsy: A scoping review.

AIM: To synthesize the evidence about the main intervention characteristics of cognitive behavioral therapies (CBTs) for individuals with cerebral palsy and identify barriers and facilitators to their success, focusing on aspects of feasibility and markers of success. METHOD: A scoping review methodology informed a literature search for papers published between 1991 and 2021. Articles were screened, reviewed, and categorized using the DistillerSR systematic review software, and critically appraised for quantitative and/or qualitative criteria. RESULTS: Out of 1265 publications identified, 14 met the inclusion criteria. Elements associated with the specific study participant characteristics (46% female; aged 6-65 years), type of CBT techniques used (third-wave [n = 6], cognitive [n = 3], cognitive and behavioral [n = 2], biofeedback training [n = 2]), and features of the study context and methodological quality (two randomized clinical trials and small sample sizes [n ≤ 12]), were identified. Most studies had psychological targets of intervention (n = 10) and secondary physiological (n = 3) or social (n = 2) objectives. Feasibility indicators were described in nearly one-third of the papers. INTERPRETATION: This study highlights the high flexibility within CBT interventions, enabling their adaptation for individuals with cerebral palsy. However, relatively little, and only low-certainty evidence was identified. More high-quality research in terms of specific CBT techniques, optimal treatment doses, and detailed population characteristics are needed.

Gross motor change after inpatient rehabilitation for children with acquired brain injury: A 10-year retrospective review.

AIM: To estimate gross motor change in inpatient school-aged children with subacute acquired brain injury (ABI), identify factors associated with gross motor change, and describe inpatient physiotherapy focus. METHOD: This retrospective chart review involved inpatient children (5-18 years) with subacute ABI who had either two Gross Motor Function Measure (GMFM-88) assessments or one GMFM-88 with another pre/post gross motor outcome measure. Outcome change scores and Goal Attainment Scaling (GAS) T scores were calculated. Regression analyses examined factors predicting gross motor change. GAS goal areas were analysed to determine physiotherapy focus. RESULTS: Of the 546 charts screened, 266 (118 female) met study criteria. The GMFM-88 was generally administered first, followed by other measures. GMFM-88 (n = 202), Community Balance and Mobility Scale (n = 89), and Six-Minute Walk Test (6MWT) (n = 98) mean change scores were 18.03% (SD 19.34), 17.85% (SD 10.77), and 142.3 m (SD 101.8) respectively. The mean GAS T score was 55.06 (SD 11.50). Lower baseline scores and increased time between assessments were most predictive of greater GMFM-88 change (r ≥ 0.40). Twenty-five percent of GAS goals were ambulation-based. INTERPRETATION: Appropriate outcome measure selection is integral to detecting gross motor change in pediatric inpatient ABI rehabilitation. Mean change score estimates can be used to compare standard inpatient rehabilitation with new treatment approaches.

Integrating Transcranial Direct Current Stimulation into an Existing Inpatient Physiotherapy Program to Enhance Motor Learning in an Adolescent with Traumatic Brain Injury: A Case Report.

PURPOSE: Describe how transcranial direct current stimulation (tDCS) was incorporated into an inpatient physiotherapy program for an adolescent with severe traumatic brain injury (TBI), detail the motor learning focus of the physiotherapy sessions, and summarize gross motor progress. METHOD: This case report describes an adolescent who received 20 minutes of anodal tDCS immediately prior to 16 physiotherapy sessions over four weeks. Potential side effects were tracked pre/post tDCS. Gross motor outcomes were measured pre-intervention, post-intervention, and three months post-intervention. Physiotherapy session content was analyzed using therapist documentation and the Motor Learning Strategies Rating Instrument. RESULTS: The youth tolerated tDCS well. The primary side effect was itchiness under the electrodes during tDCS sessions. His mobility progressed from wheelchair use pre- 'tDCS + physiotherapy' to ambulation with a walker post-intervention. His Gross Motor Function Measure score increased 33.1% points pre/post intervention. Session tasks often had several foci (e.g., skill acquisition, strength, and balance) with task focus changing as the youth progressed. Various motor learning strategies were layered within tasks to support performance and learning. CONCLUSIONS: tDCS was successfully integrated into an existing inpatient physiotherapy program for an adolescent with TBI. This protocol provides a structure for implementing, monitoring, and measuring tDCS + physiotherapy in pediatric rehabilitation.

Exploring Physiotherapists' Use of Motor Learning Strategies in Gait-Based Interventions for Children with Cerebral Palsy.

Aim: This study investigated physiotherapists' experiences using motor learning strategies (MLS) in gait-based interventions for children with cerebral palsy (CP). The objectives were to explore how child characteristics, physiotherapist decision-making, and treatment approach influenced intentional MLS use.Methods: Semi-structured interviews were conducted with eight physiotherapists who provided gym- and/or Lokomat-based treatment to children with CP. Interviews were analyzed using directed content analysis and a modified constant comparison method.Results: Three themes described their experiences: (1) MLS use is driven by the unique aspects of the child, physiotherapist, and intervention; (2) The use and description of motor learning content varies among physiotherapists; and (3) The Lokomat is "the same but different." Child characteristics were at the forefront of MLS selection in both interventions. The terminology used to describe MLS use varied considerably among therapists. They used similar clinical decision-making in gym- and Lokomat-based interventions.Conclusions: Conscious reflection on the factors affecting MLS use could facilitate related clinical decision-making in physiotherapy interventions for children with CP. Increased awareness of MLS and use of a structured framework for reporting MLS are required to promote intentional MLS use and generate CP-specific evidence-based MLS research.

Reliability of the Motor Learning Strategies Rating Instrument in physiotherapy intervention for children with cerebral palsy.

AIM: To evaluate the reliability of the Motor Learning Strategies Rating Instrument (MLSRI-20) in gait-based, video-recorded physiotherapy interventions for children with cerebral palsy (CP). METHOD: Thirty videos of 18 children with CP, aged 6 to 17 years, participating in either traditional or Lokomat-based physiotherapy interventions were rated using the MLSRI-20. Physiotherapist raters provided general and item-specific feedback after rating each video, which was used when interpreting reliability results. RESULTS: Both interrater and intrarater reliability of the MLSRI-20 total score was good. The interrater reliability intraclass correlation coefficient (ICC) was 0.78 with a 95% confidence interval (CI) of 0.53-0.89 and a coefficient of variation (CV) of 11.8%. The intrarater reliability ICC was 0.89 with a 95% CI of 0.76-0.95 and CV of 7.8%. Rater feedback identified task delineation and interpretation of therapist verbalizations as sources of interrater reliability-related scoring challenges. INTERPRETATION: The MLSRI-20 is a reliable tool for measuring the extent to which a physiotherapist uses motor learning strategies during a video-recorded intervention. These results have clinical and research implications for documenting and analyzing the motor learning content of physiotherapy interventions for children with CP. WHAT THIS PAPER ADDS: The Motor Learning Strategies Rating Instrument (MLSRI-20) is reliable for use by trained physiotherapist raters. Measuring motor learning strategies can identify active 'ingredients' in physiotherapy interventions for children with cerebral palsy. The MLSRI-20 promotes a common language in motor learning.

PRISMA Extension for Scoping Reviews (PRISMA-ScR): Checklist and Explanation.

Scoping reviews, a type of knowledge synthesis, follow a systematic approach to map evidence on a topic and identify main concepts, theories, sources, and knowledge gaps. Although more scoping reviews are being done, their methodological and reporting quality need improvement. This document presents the PRISMA-ScR (Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews) checklist and explanation. The checklist was developed by a 24-member expert panel and 2 research leads following published guidance from the EQUATOR (Enhancing the QUAlity and Transparency Of health Research) Network. The final checklist contains 20 essential reporting items and 2 optional items. The authors provide a rationale and an example of good reporting for each item. The intent of the PRISMA-ScR is to help readers (including researchers, publishers, commissioners, policymakers, health care providers, guideline developers, and patients or consumers) develop a greater understanding of relevant terminology, core concepts, and key items to report for scoping reviews.

What is the impact of user affect on motor learning in virtual environments after stroke? A scoping review.

PURPOSE: The purported affective impact of virtual reality (VR) and active video gaming (AVG) systems is a key marketing strategy underlying their use in stroke rehabilitation, yet little is known as to how affective constructs are measured or linked to intervention outcomes. The purpose of this scoping review is to 1) explore how motivation, enjoyment, engagement, immersion and presence are measured or described in VR/AVG interventions for patients with stroke; 2) identify directional relationships between these constructs; and 3) evaluate their impact on motor learning outcomes. METHODS: A literature search was undertaken of VR/AVG interventional studies for adults post-stroke published in Medline, PEDro and CINAHL databases between 2007 and 2017. Following screening, reviewers used an iterative charting framework to extract data about construct measurement and description. A numerical and thematic analytical approach adhered to established scoping review guidelines. RESULTS: One hundred fifty-five studies were included in the review. Although the majority (89%; N = 138) of studies described at least one of the five constructs within their text, construct measurement took place in only 32% (N = 50) of studies. The most frequently described construct was motivation (79%, N = 123) while the most frequently measured construct was enjoyment (27%, N = 42). A summative content analysis of the 50 studies in which a construct was measured revealed that constructs were described either as a rationale for the use of VR/AVGs in rehabilitation (76%, N = 38) or as an explanation for intervention results (56%, N = 29). 38 (76%) of the studies proposed relational links between two or more constructs and/or between any construct and motor learning. No study used statistical analyses to examine these links. CONCLUSIONS: Results indicate a clear discrepancy between the theoretical importance of affective constructs within VR/AVG interventions and actual construct measurement. Standardized terminology and outcome measures are required to better understand how enjoyment, engagement, motivation, immersion and presence contribute individually or in interaction to VR/AVG intervention effectiveness.

Learning and transfer of complex motor skills in virtual reality: a perspective review.

The development of more effective rehabilitative interventions requires a better understanding of how humans learn and transfer motor skills in real-world contexts. Presently, clinicians design interventions to promote skill learning by relying on evidence from experimental paradigms involving simple tasks, such as reaching for a target. While these tasks facilitate stringent hypothesis testing in laboratory settings, the results may not shed light on performance of more complex real-world skills. In this perspective, we argue that virtual environments (VEs) are flexible, novel platforms to evaluate learning and transfer of complex skills without sacrificing experimental control. Specifically, VEs use models of real-life tasks that afford controlled experimental manipulations to measure and guide behavior with a precision that exceeds the capabilities of physical environments. This paper reviews recent insights from VE paradigms on motor learning into two pressing challenges in rehabilitation research: 1) Which training strategies in VEs promote complex skill learning? and 2) How can transfer of learning from virtual to real environments be enhanced? Defining complex skills by having nested redundancies, we outline findings on the role of movement variability in complex skill acquisition and discuss how VEs can provide novel forms of guidance to enhance learning. We review the evidence for skill transfer from virtual to real environments in typically developing and neurologically-impaired populations with a view to understanding how differences in sensory-motor information may influence learning strategies. We provide actionable suggestions for practicing clinicians and outline broad areas where more research is required. Finally, we conclude that VEs present distinctive experimental platforms to understand complex skill learning that should enable transfer from therapeutic practice to the real world.

The Effects of a 5-Day Virtual-Reality Based Exercise Program on Kinematics and Postural Muscle Activity in Youth with Cerebral Palsy.

Aims: To determine the effects of a 5-day virtual reality (VR)-based intervention on anticipatory and reactive mechanisms of postural control in children and adolescents with cerebral palsy (CP). Methods: Eleven youth with CP (GMFCS levels I and II), ages 7-17, were allocated to intervention (N = 5) and control (N = 6) groups. Both groups attended balance assessment sessions 1 week apart. Participants in the intervention group received 1-hour one-on-one physiotherapist-supervised VR balance games for 5 consecutive days between assessments. For balance assessments, participants stood erect with eyes open on a movable platform that translated progressively through four speeds in the anterior/posterior direction. Participants performed two trials each of experimenter-triggered and self-triggered perturbations. Postural muscle activity and kinematics were recorded. The Anchoring Index and body segment cross-correlations were calculated as an indication of body stabilization, and the number of steps taken to regain balance/avoid falling were counted. Mann-Whitney U tests for between group differences in change scores were undertaken with an accepted significance level of 0.01. Results: No consistent differences in change scores were identified between groups. Conclusions: There was no effect of a 5-day VR-based intervention on postural control mechanisms used in response to oscillating platform perturbations. Subsequent studies will further tailor VR interventions to patients' functional balance needs.

Active Video Gaming for Children with Cerebral Palsy: Does a Clinic-Based Virtual Reality Component Offer an Additive Benefit? A Pilot Study.

AIMS: To compare changes in gross motor skills and functional mobility between ambulatory children with cerebral palsy who underwent a 1-week clinic-based virtual reality intervention (VR) followed by a 6-week, therapist-monitored home active video gaming (AVG) program and children who completed only the 6-week home AVG program. METHODS: Pilot non-randomized controlled trial. Five children received 1 hour of VR training for 5 days followed by a 6-week home AVG program, supervised online by a physical therapist. Six children completed only the 6-week home AVG program. The Gross Motor Function Measure Challenge Module (GMFM-CM) and Six Minute Walk Test (6MWT) evaluated change. RESULTS: There were no significant differences between groups. The home AVG-only group demonstrated a statistically and clinically significant improvement in GMFM-CM scores following the 6-week AVG intervention (median difference 4.5 points, interquartile range [IQR] 4.75, p = 0.042). The VR + AVG group demonstrated a statistically and clinically significant decrease in 6MWT distance following the intervention (median decrease 68.2 m, IQR 39.7 m, p = 0.043). All 6MWT scores returned to baseline at 2 months post-intervention. CONCLUSION: Neither intervention improved outcomes in this small sample. Online mechanisms to support therapist-child communication for exercise progression were insufficient to individualize exercise challenge.

A scoping review on the conduct and reporting of scoping reviews.

BACKGROUND: Scoping reviews are used to identify knowledge gaps, set research agendas, and identify implications for decision-making. The conduct and reporting of scoping reviews is inconsistent in the literature. We conducted a scoping review to identify: papers that utilized and/or described scoping review methods; guidelines for reporting scoping reviews; and studies that assessed the quality of reporting of scoping reviews. METHODS: We searched nine electronic databases for published and unpublished literature scoping review papers, scoping review methodology, and reporting guidance for scoping reviews. Two independent reviewers screened citations for inclusion. Data abstraction was performed by one reviewer and verified by a second reviewer. Quantitative (e.g. frequencies of methods) and qualitative (i.e. content analysis of the methods) syntheses were conducted. RESULTS: After searching 1525 citations and 874 full-text papers, 516 articles were included, of which 494 were scoping reviews. The 494 scoping reviews were disseminated between 1999 and 2014, with 45% published after 2012. Most of the scoping reviews were conducted in North America (53%) or Europe (38%), and reported a public source of funding (64%). The number of studies included in the scoping reviews ranged from 1 to 2600 (mean of 118). Using the Joanna Briggs Institute methodology guidance for scoping reviews, only 13% of the scoping reviews reported the use of a protocol, 36% used two reviewers for selecting citations for inclusion, 29% used two reviewers for full-text screening, 30% used two reviewers for data charting, and 43% used a pre-defined charting form. In most cases, the results of the scoping review were used to identify evidence gaps (85%), provide recommendations for future research (84%), or identify strengths and limitations (69%). We did not identify any guidelines for reporting scoping reviews or studies that assessed the quality of scoping review reporting. CONCLUSION: The number of scoping reviews conducted per year has steadily increased since 2012. Scoping reviews are used to inform research agendas and identify implications for policy or practice. As such, improvements in reporting and conduct are imperative. Further research on scoping review methodology is warranted, and in particular, there is need for a guideline to standardize reporting.

Advancing scoping study methodology: a web-based survey and consultation of perceptions on terminology, definition and methodological steps.

BACKGROUND: Scoping studies (or reviews) are a method used to comprehensively map evidence across a range of study designs in an area, with the aim of informing future research practice, programs and policy. However, no universal agreement exists on terminology, definition or methodological steps. Our aim was to understand the experiences of, and considerations for conducting scoping studies from the perspective of academic and community partners. Primary objectives were to 1) describe experiences conducting scoping studies including strengths and challenges; and 2) describe perspectives on terminology, definition, and methodological steps. METHODS: We conducted a cross-sectional web-based survey with clinicians, educators, researchers, knowledge users, representatives from community-based organizations, graduate students, and policy stakeholders with experience and/or interest in conducting scoping studies to gain an understanding of experiences and perspectives on the conduct and reporting of scoping studies. We administered an electronic self-reported questionnaire comprised of 22 items related to experiences with scoping studies, strengths and challenges, opinions on terminology, and methodological steps. We analyzed questionnaire data using descriptive statistics and content analytical techniques. Survey results were discussed during a multi-stakeholder consultation to identify key considerations in the conduct and reporting of scoping studies. RESULTS: Of the 83 invitations, 54 individuals (65 %) completed the scoping questionnaire, and 48 (58 %) attended the scoping study meeting from Canada, the United Kingdom and United States. Many scoping study strengths were dually identified as challenges including breadth of scope, and iterative process. No consensus on terminology emerged, however key defining features that comprised a working definition of scoping studies included the exploratory mapping of literature in a field; iterative process, inclusion of grey literature; no quality assessment of included studies, and an optional consultation phase. We offer considerations for the conduct and reporting of scoping studies for researchers, clinicians and knowledge users engaging in this methodology. CONCLUSIONS: Lack of consensus on scoping terminology, definition and methodological steps persists. Reasons for this may be attributed to diversity of disciplines adopting this methodology for differing purposes. Further work is needed to establish guidelines on the reporting and methodological quality assessment of scoping studies.

A knowledge translation intervention to enhance clinical application of a virtual reality system in stroke rehabilitation.

BACKGROUND: Despite increasing evidence for the effectiveness of virtual reality (VR)-based therapy in stroke rehabilitation, few knowledge translation (KT) resources exist to support clinical integration. KT interventions addressing known barriers and facilitators to VR use are required. When environmental barriers to VR integration are less amenable to change, KT interventions can target modifiable barriers related to therapist knowledge and skills. METHODS: A multi-faceted KT intervention was designed and implemented to support physical and occupational therapists in two stroke rehabilitation units in acquiring proficiency with use of the Interactive Exercise Rehabilitation System (IREX; GestureTek). The KT intervention consisted of interactive e-learning modules, hands-on workshops and experiential practice. Evaluation included the Assessing Determinants of Prospective Take Up of Virtual Reality (ADOPT-VR) Instrument and self-report confidence ratings of knowledge and skills pre- and post-study. Usability of the IREX was measured with the System Usability Scale (SUS). A focus group gathered therapist experiences. Frequency of IREX use was recorded for 6 months post-study. RESULTS: Eleven therapists delivered a total of 107 sessions of VR-based therapy to 34 clients with stroke. On the ADOPT-VR, significant pre-post improvements in therapist perceived behavioral control (p = 0.003), self-efficacy (p = 0.005) and facilitating conditions (p =0.019) related to VR use were observed. Therapist intention to use VR did not change. Knowledge and skills improved significantly following e-learning completion (p = 0.001) and was sustained 6 months post-study. Below average perceived usability of the IREX (19th percentile) was reported. Lack of time was the most frequently reported barrier to VR use. A decrease in frequency of perceived barriers to VR use was not significant (p = 0.159). Two therapists used the IREX sparingly in the 6 months following the study. Therapists reported that client motivation to engage with VR facilitated IREX use in practice but that environmental and IREX-specific barriers limited use. CONCLUSIONS: Despite increased knowledge and skills in VR use, the KT intervention did not alter the number of perceived barriers to VR use, intention to use or actual use of VR. Poor perceived system usability had an impact on integration of this particular VR system into clinical practice.

Evaluating the Nintendo Wii for assessing return to activity readiness in youth with mild traumatic brain injury.

Adolescents with mild traumatic brain injuries (MTBI) are at substantial risk for repeat injury if they return to activity too soon. Post-concussion symptoms and impaired balance are two factors that limit return to activity. Post-injury assessments that challenge activity tolerance and balance skills are needed to ensure readiness to return to activity. This cross-sectional study evaluated the Nintendo Wii as a measure of exertion (heart rate [HR], respiration rate [RR], and caloric expenditure) and balance testing for youth with MTBI in a clinical setting. Twenty-four youth with MTBI, ages 9-18, played six Wii games. The Bruininks-Oseretsky Test of Motor Proficiency 2nd edition (BOT-2) and the Community Balance and Mobility Scale (CBM) were used as balance indicators. The Wii Fit Running game demonstrated the highest caloric expenditure and HR (p = .010). Frequency counts of balance loss during Wii game play did not correlate with performance on the BOT-2 or the CBM. Type, number, and time since injury were predictive of balance performance on the CBM (p = .008). Findings provide preliminary evidence for the use of the Wii as an exertion challenge to evaluate tolerance for exercise post-concussion. Frequency count of balance loss during Wii game play, however, was not a valid measure of balance impairment post-MTBI.

When is virtual reality "therapy"?

The use of virtual reality (VR) systems within physical rehabilitation clinical practice and research is rapidly developing, highlighting the need for consensus as to the meaning and relevance of the label "VR therapy." The purpose of this communication is to argue that explicit examination of the inferences underlying this label and discussion regarding the role of clinicians in VR implementation are required. In this vein, we propose what we consider to be a more relevant label and discuss the need for evidence to support knowledge translation initiatives for therapists interested in integrating VR systems within clinical practice.

The motor learning strategy instrument: interrater reliability within usual and virtual reality physical therapy interventions.

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.

Motor Evoked Potential Amplitude in Motor Behavior-based Transcranial Direct Current Stimulation Studies: A Systematic Review.

Motor evoked potential amplitude (MEPamp) is frequently measured in transcranial direct current stimulation (tDCS) studies that target the primary motor cortex (M1), and a subset of these studies involve motor behavior. This systematic review explored the role of MEPamp as an indicator of neural change in M1-targeted tDCS studies involving motor behavior (i.e., motor practice and/or evaluation of motor performance) in healthy individuals, and examined the association between changes in motor performance and MEPamp. We executed our search strategy across four bibliographic databases. Twenty-two manuscripts met eligibility criteria. While anodal tDCS combined with motor practice frequently increased MEPamp, MEPamp outcomes did not necessarily align with changes in motor performance. Thus, MEPamp may not be the most appropriate indicator of neural change in tDCS studies that aim to improve motor performance.

Usual and virtual reality video game-based physiotherapy for children and youth with acquired brain injuries.

Little is known about how therapists promote learning of functional motor skills for children with acquired brain injuries. This study explores physiotherapists' description of these interventions in comparison to virtual reality (VR) video game-based therapy. Six physiotherapists employed at a children's rehabilitation center participated in semi-structured interviews, which were transcribed and analyzed using thematic analysis. Physiotherapists describe using interventions that motivate children to challenge performance quality and optimize real-life functioning. Intervention strategies are influenced by characteristics of the child, parent availability to practice skills outside therapy, and therapist experience. VR use motivates children to participate, but can influence therapist use of verbal strategies and complicate interventions. Physiotherapists consider unique characteristics of this population when providing interventions that promote learning of motor skills. The VR technology has advantageous features but its use with this population can be challenging; further research is recommended.

Reliability of the motor learning strategy rating instrument for children and youth with acquired brain injury.

PURPOSE: To evaluate reliability and feasibility of the Motor Learning Strategy Rating Instrument (MLSRI) in children with acquired brain injury (ABI). The MLSRI quantifies the extent to which motor learning strategies (MLS) are used within physiotherapy (PT) interventions. METHODS: PT sessions conducted by ABI team physiotherapists with a convenience sample of children with ABI (4-18 years) were videotaped and independently scored later by two raters trained in MLSRI use. Intraclass correlation coefficients (ICCs) and 95% confidence intervals (CIs) estimated intra- and inter-rater reliability. RESULTS: Eighteen PT sessions were evaluated. Intra- and inter-rater reliability ICCs for total score were 0.86 (95% CI: 0.66-0.94) and 0.50 (95% CI: 0.08-0.78), respectively. MLSRI category ICCs were 0.56-0.86 (intra-rater) and 0.16-0.84 (inter-rater). CONCLUSIONS: Intra-rater reliability of MSLRI total score was excellent. Moderate inter-rater reliability may partially be due to inconsistent item interpretation between raters. Revisions and further reliability testing are required before recommending the MLSRI for clinical and research use.
