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

A Case Report Emphasizing an Early Approach in a Patient With Diffuse Axonal Injury

Diffuse axonal injury (DAI) is a severe and frequently life-altering form of traumatic brain injury that is brought on by forces of rapid acceleration as well as deceleration impacting the brain. DAI primarily stems from mechanical forces that lead to the widespread disruption of axons throughout the brain. Unlike focal injuries that affect a specific brain region, DAI manifests as multifocal axonal damage, often impairing vital neural connections. This injury occurs due to shear and tensile forces during traumatic events, such as car accidents, falls, and sports-related incidents. This current case report includes a 19-year-old male who had a fall from his bike and was hospitalised with brain trauma. A Magnetic resonance imaging (MRI) scan was done, which revealed a case of DAI, and a computed tomography (CT) scan of the brain revealed the extra-calvarial soft tissue swelling in the left parietal region. Small haemorrhagic contusions involved the right ganglio-capsular region. Several integrative techniques, including joint approximation, proprioceptive neuromuscular facilitation (PNF) rhythmic initiation, D1 flexion-extension, and patient education, were used to manage the patient. The patient's development was evaluated using outcome measures, such as the functional independence measure (FIM) and the Glasgow coma scale (GCS). Thus, we conclude that completing physiotherapy exercises consistently helps patients achieve their highest level of functional independence and also enhances their quality of life.

Investigating the Effect of Leap Motion on Upper Extremity Rehabilitation in Children with Cerebral Palsy: A Randomized Controlled Trial

In this randomized clinical trial, we look for the following questions' answer: How does the integration of LMC affect (1) upper extremity (UE) function, (2) grip strength, and (3) lateral and palmar pinch strength in children with cerebral palsy (CP), in comparison with conventional rehabilitation methods? Twenty patients were randomly assigned to LMC (case) or conventional (control) groups. The grip, lateral and palmar pinch forces increased in case group patients more than control group both at the end of intervention (P < .001 for all three), and at 20 weeks' follow-up (P values 0.035, 0.002, and 0.002). The Quality of Upper Extremity Skills Test (QUEST) score changes were similar between two groups, except for grasp score at the end of step 2 and 3 (P = .04 and 0.01, respectively). The addition of LMC to the rehabilitation program of patients with CP may improve the UE motor function outcomes.

The Effects of Virtual Reality Physiotherapy Interventions on Cardiopulmonary Function and Breathing Control in Cystic Fibrosis: A Systematic Review

Motivation and adherence are the main factors that limit participation in physiotherapy exercise sessions and airway clearance in cystic fibrosis (CF) population. One of the newly developed techniques is to use virtual reality (VR) games to increase motivation and adherence during exercise sessions for this population. However, this area is still poorly investigated. This review aims to evaluate, summarize, and review published literature regarding the effects of VR exercise on cardiopulmonary function and the use of VR games as a tool for airway clearance technique in CF population. A systematic search was conducted using PEDro, MEDLINE, AMED, CINAHL Plus, and relevant associated keywords. Seventy-three citations were identified from the search, of which 10 were included in this review. Overall, the use of VR was found to have positive effects on cardiac function and improved adherence and motivation during the exercise sessions in people with CF. Incorporating VR into exercise and airway clearance interventions may be beneficial for people with CF. However, further studies with larger sample size and wider range of disease severity are required to be conducted in future.

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.

Perks of Early Physical Therapy Rehabilitation for a Patient With Diffuse Axonal Injury

Traumatic brain injury (TBI) is characterized as any neurological trauma that develops after birth and therefore is completely unconnected from congenital anomalies, developmental disorders, or gradual processes. People who have survived accidents or other severe head injuries that left them with brain damage have been linked to memory loss and disability. On February 9, 2022, a 23-year-old individual was taken to a nearby hospital with a head injury after being involved in a traffic accident that morning while under the influence of alcohol. After several tests, the individual was identified as having a diffuse axonal injury in the anterolateral aspect of the pons, which was confirmed by an MRI and CT scan of the brain. The patient had been managed conservatively with appropriate medications like (tab Zifi® 200mg, tab Epilive® 500mg, tab Strocit plus®, tab Modalert®, tab Oxynerve plus®, etc.) along with physiotherapy, and other supportive treatments. Key indicators involve recovery of consciousness, normalization of muscle tone, earlier onset of movements, adequate strength, and quality of life. The TBI rehabilitation service is advantageous, as supported by proportionally massive progress in exercise tolerance and overall health. The above case study serves as an example of an extensive rehabilitation program for patients who have undergone conservative treatment after suffering a diffuse axonal injury.

Use of Motor Learning Strategies in Occupational Therapy for Children and Youth with Acquired Brain Injury

Motor learning strategies (MLS) can be used to promote motor skills acquisition in children and youth with acquired brain injury (ABI). While occupational therapists (OTs) likely use MLS in clinical practice, research has not investigated the extent and variety of their application.Aims: This study explored MLS use by OTs in pediatric ABI and factors influencing their application.Method: Individual video-recorded occupational therapy sessions for a sample of eight children/youth (ages 4-16) with ABI were evaluated via mixed methods approach. The Motor Learning Strategies Rating Instrument (MLSRI-22) quantified the extent of MLS use in each video. Directed content analysis of the videos explored the factors influencing how and when MLS were applied.Results: The most frequently used MLS were promoting problem solving, encouragement, directing attention to the body, permitting errors as part of learning, repetitive practice, and whole practice. Three themes described how and when the OTs used MLS: 1) Getting buy-in, 2) Going with the flow, and 3) Movement and thinking go hand-in-hand.Conclusions: The OTs frequently used MLS with children with ABI, appearing to select MLS based on factors related to the child, task, and environment. These findings are fundamental to future exploration of OT decision-making and evaluation of MLS effectiveness.

Leap Motion Controller-based training for upper extremity rehabilitation in children and adolescents with physical disabilities: A randomized controlled trial

STUDY DESIGN

Randomized controlled trial.

INTRODUCTION

Juvenile idiopathic arthritis (JIA), cerebral palsy (CP), and brachial plexus birth injury (BPBI) are the most common disorders that cause upper extremity impairments in children and adolescents. Leap Motion Controller-based training (LMCBT) is a novel therapeutic method for upper extremity rehabilitation.

PURPOSE OF THE STUDY

The aim of the present study was to investigate the potential efficacy of an 8-week LMCBT program set as an upper extremity rehabilitation program by comparing conventional rehabilitation program in children and adolescents with physical disabilities such as JIA, CP, and BPBI.

METHODS

A randomized control trial which included children and adolescents of different disabilities (JIA, CP, BPBI) were grouped according to their diagnosis. All patients were randomized into 2 groups namely LMCBT (group I) and conventional treatment (group II) for the treatment (3 days/8 weeks). Duruoz Hand Index and Jebson Taylor Hand Function Test were used as primary outcomes. Secondary outcomes included the nine-hole peg test, Childhood Health Assessment Questionnaire, and assessments of grip and pinch strength using a dynamometer.

RESULTS

One hundred three patients were included in the study, and 92 of them completed the treatment. After treatment, significant differences were found in Childhood Health Assessment Questionnaire, Duruoz Hand Index, Jebson Taylor Hand Function Test, nine-hole peg test, and grip and pinch strength scores in almost all groups (effect size [ES] = 0.10 to -0.77 for group I and 0.09 to -0.70 for group II in CP; ES = 0.31 to 2.65 for the group I and 0.12 to 1.66 for group II in JIA; and ES = 0 to -0.44 for group I and 0.08 to -0.62 for group II in BPBI) (P < .05). Comparisons between LMCBT and conventional treatment groups showed similar results in all parameters in all disease groups (P > .05).

CONCLUSIONS

This study has quantitatively shown that LMCBT should be used as an effective alternative treatment option in children and adolescents with physical disabilities.

Virtual Reality for Neurorehabilitation and Cognitive Enhancement

Our access to computer-generated worlds changes the way we feel, how we think, and how we solve problems. In this review, we explore the utility of different types of virtual reality, immersive or non-immersive, for providing controllable, safe environments that enable individual training, neurorehabilitation, or even replacement of lost functions. The neurobiological effects of virtual reality on neuronal plasticity have been shown to result in increased cortical gray matter volumes, higher concentration of electroencephalographic beta-waves, and enhanced cognitive performance. Clinical application of virtual reality is aided by innovative brain–computer interfaces, which allow direct tapping into the electric activity generated by different brain cortical areas for precise voluntary control of connected robotic devices. Virtual reality is also valuable to healthy individuals as a narrative medium for redesigning their individual stories in an integrative process of self-improvement and personal development. Future upgrades of virtual reality-based technologies promise to help humans transcend the limitations of their biological bodies and augment their capacity to mold physical reality to better meet the needs of a globalized world.

How Commercially Available Virtual Reality-Based Interventions Are Delivered and Reported in Gait, Posture, and Balance Rehabilitation: A Systematic Review

OBJECTIVE

Virtual reality (VR) technologies are increasingly used in physical rehabilitation; however, it is unclear how VR interventions are being delivered, and, in particular, the role of the therapist remains unknown. The purpose of this study was to systematically evaluate how commercially available VR technologies are being implemented in gait, posture, and balance rehabilitation, including justification, content, procedures, and dosage of the intervention and details of the therapist role.

METHODS

Five databases were searched between 2008 and 2018. Supervised interventional trials with >10 adult participants using commercially available VR technologies to address mobility limitations were independently selected by 2 authors. One author extracted reported intervention characteristics into a predesigned table and assessed methodological quality, which was independently verified by a second author. A total of 29 studies were included.

RESULTS

Generally, minimal clinical reasoning was provided to justify technology or activity selection, with recreational systems and games used most commonly (n = 25). All but 1 study used a single interventional technology. When explicitly described, the intervention was delivered by a physical therapist (n = 14), a therapist assistant (n = 2), both (n = 1), or an occupational therapist (n = 1). Most studies reported supervision (n = 12) and safeguarding (n = 8) as key therapist roles, with detail of therapist feedback less frequently reported (n = 4). Therapist involvement in program selection, tailoring, and progression was poorly described.

CONCLUSION

Intervention protocols of VR rehabilitation studies are incompletely described and generally lack detail on clinical rationale for technology and activity selection and on the therapist role in intervention design and delivery, hindering replication and translation of research into clinical practice. Future studies utilizing commercially available VR technologies should report all aspects of intervention design and delivery and consider protocols that allow therapists to exercise clinical autonomy in intervention delivery.

IMPACT STATEMENT

The findings of this systematic review have highlighted that VR rehabilitation interventions targeting gait, posture, and balance are primarily delivered by physical therapists, whose most reported role was supervision and safeguarding. There was an absence of detail regarding complex clinical skills, such as tailoring of the intervention and reasoning for the choice of technology and activity. This uncertainty around the role of the therapist as an active ingredient in VR-based rehabilitation hinders the development of implementation guidelines. To inform the optimal involvement of therapists in VR rehabilitation, it is essential that future studies report on all aspects of VR intervention design and delivery.

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.

Facilitating the Implementation of Virtual Reality-Based Therapies in Pediatric Rehabilitation

Aims: Evaluate the impact of a multifaceted knowledge translation (KT) strategy for the implementation of virtual reality (VR) intervention by rehabilitation clinicians in a pediatric hospital setting.Methods: Eleven therapists were recruited and completed a questionnaire on perceptions on VR usage. A multifaceted KT strategy was implemented over five months. VR usage was tracked and clinician perceptions were reassessed. Baseline characteristics were summarized using descriptive statistics and a Wilcoxon signed rank sum test evaluated changes pre- and post-KT.Results: Perceived ease of use, behavioral control, self-efficacy, and barriers to use improved significantly post-KT; however, intention to use did not. Usage was higher pre-KT than the last two months of KT. Pre-KT, barriers included system setup and use, knowledge of games, and lack of resources, whereas post-KT, they were the lack of appropriate patients and patient-specific experience. KT supports and patient engagement were reasons for continued use.Conclusions: This study highlights the importance of supporting clinicians when implementing VR in clinical rehabilitation. Clinicians benefit from experiential and individualized learning opportunities, peer-led coaching, and hands-on training. Whether these strategies translate to increased usage and how usage is influenced by environmental factors (i.e. lack of appropriate clients) warrants additional research.

E-Survey of Current International Physiotherapy Practice for Children with Ataxia Following Surgical Resection of Posterior Fossa Tumour

Objective

To determine current international practice regarding physiotherapy input for children with ataxia following surgery for posterior fossa tumour. Design: An e-survey covering the following domains: participant demographics, treatment/ intervention, virtual training, intensity/timing of treatment, and aims and outcomes of physiotherapy management.

Participants

Physiotherapists involved in the management of children with ataxia following surgical resection of posterior fossa tumour. Participants were contacted via 6 key groups; Paediatric Oncology Physiotherapy Network (POPs), Association of Paediatric Chartered Physiotherapists (APCP), European Paediatric Neurology Society (EPNS), International Society of Paediatric Oncology (SIOP)-Europe Brain Tumour Group, Posterior Fossa Society (PFS), and Pediatric Oncology Special Interest Group (SIG) (American Physical Therapy Association).

Results

A total of 96 physiotherapists participated: UK (n =53), rest of Europe (n = 23), USA/ Canada (n = 10), and Australia/NZ (n = 10). The most common physiotherapy interventions used were balance exercises, gait re-education and proximal control activities. The most frequently used adjuncts to treatment were mobility aids and orthotics. Challenges reported regarding physiotherapy treatment were: reduced availability of physiotherapy input following discharge from the acute setting, lack of evidence, impact of adjuvant oncology treatment, and psychosocial impact.

Conclusion

This e-survey provides an initial scoping review of international physiotherapy practice in this area. It establishes a foundation for future research on improving rehabilitation of ataxia in this population.

Heart rate agreement between the 20-meter shuttle run test and virtual system in healthy children: a cross-sectional study

Background

Earlier studies evaluated the physiological responses to video games in children with different clinical conditions; however, no study has compared active video games with an incremental field test in healthy children. The purpose of this study was to verify the agreement between the 20-m shuttle run test (20 m-SRT) and virtual system (VS).

Methods

This is a cross-sectional study of 235 children (9.0 ± 0.8 years, 109 boys). The two tests were performed one week apart and the children were instructed not to engage in any physical exercise or sports in the 24 h preceding each test. Their resting heart rate was monitored for one minute and then throughout the tests. To evaluate the influence of motivation on the 20 m SRT and (VS), at the end of the tests the children were asked to rate their motivation on a scale of zero to 10, zero being “not cool” and 10 “awesome”. Perceived exertion at the end of the tests was assessed using the modified Borg scale.

Results

Maximum heart rate (HRmax) did not differ between the 20 m-SRT and VS (194.4 ± 10.2 bpm vs. 193.2 ± 13.8 bpm, respectively). Both tests were similar for intensity > and < 96% HRmax. The children showed greater exertion on the Borg scale and motivation during the VS. The multiple logistic regression model showed that motivation (p = 0.98), sex (p = 0.53), age (p = 0.61), nutritional status (p = 0.65), and speed (p = 0.18) were not predictive factors of the child’s reaching HRmax.

Conclusion

VS can be used as a tool to evaluate the intensity of maximal exercise tests, given that the percentage of children who achieved HRmax did not differ between the VS and 20 m SRT. The perceived exertion scales were correlated, but only the modified Borg scale correlated with HRmax in the 20 m SRT. The tests are motivational, and most children obtained the maximum VS score.

Barriers, Facilitators and Interventions to Support Virtual Reality Implementation in Rehabilitation: A Scoping Review

Virtual reality and active video games (VR/AVGs) are promising rehabilitation tools because of their potential to facilitate abundant, motivating, and feedback-rich practice. However, clinical adoption remains low despite a growing evidence base and the recent development of clinically accessible and rehabilitation-specific VR/AVG systems. Given clinicians' eagerness for resources to support VR/AVG use, a critical need exists for knowledge translation (KT) interventions to facilitate VR/AVG integration into clinical practice. KT interventions have the potential to support adoption by targeting known barriers to, and facilitators of, change. This scoping review of the VR/AVG literature uses the Theoretical Domains Framework (TDF) to (1) structure an overview of known barriers and facilitators to clinical uptake of VR/AVGs for rehabilitation; (2) identify KT strategies to target these factors to facilitate adoption; and (3) report the results of these strategies. Barriers/facilitators and evaluated or proposed KT interventions spanned all but 1 and 2 TDF domains, respectively. Most frequently cited barriers/facilitators were found in the TDF domains of Knowledge, Skills, Beliefs About Capabilities, Beliefs About Consequences, Intentions, Goals, Environmental Context and Resources, and Social Influences. Few studies empirically evaluated KT interventions to support adoption; measured change in VR/AVG use did not accompany improvements in self-reported skills, attitudes, and knowledge. Recommendations to target frequently identified barriers include technology development to meet end-user needs more effectively, competency development for end-users, and facilitated VR/AVG implementation in clinical settings. Subsequent research can address knowledge gaps in both clinical and VR/AVG implementation research, including on KT intervention effectiveness and unexamined TDF domain barriers. LEVEL OF EVIDENCE: IV.

Virtual Reality and Active Videogame-Based Practice, Learning Needs, and Preferences: A Cross-Canada Survey of Physical Therapists and Occupational Therapists

OBJECTIVE

Describe the clinical use of virtual reality (VR)/active videogaming (AVG) by physical therapists (PTs) and occupational therapists (OTs) in Canada, identify usage barriers and facilitators, evaluate factors that predict intention to use VR/AVGs, and determine therapists' learning needs.

DESIGN

Cross-sectional survey.

MATERIALS AND METHODS

Online survey of therapists in Canada who were members of 1 of 26 professional PT or OT colleges or associations using the Assessing Determinants Of Prospective Take-up of Virtual Reality (ADOPT-VR2) Instrument.

RESULTS

We received 1071 (506 PTs, 562 OTs, 3 dual-trained) responses. Forty-six percent had clinical VR/AVG experience; only 12% reported current use, with the Wii being the most clinically accessible (41%) system. Therapists used VR/AVGs primarily in rehabilitation (32%) and hospital (29%) settings, preferentially targeting balance (39.3%) and physical activity (19.8%) outcomes. Stroke (25.8%), brain injury (15.3%), musculoskeletal (14.9%), and cerebral palsy (10.5%) populations were most frequently treated. Therapists with VR/AVG experience rated all ADOPT-VR2 constructs more highly than did those without experience (P < 0.001). Factors predictive of intention to use VR included the technology's perceived usefulness and therapist self-efficacy in VR/AVG use (P < 0.001). Highest-rated barriers to VR/AVG use were lack of funds, space, time, support staff, and appropriate clients, whereas facilitators included client motivation, therapist knowledge, and management support. Most (76%) respondents were interested in learning more.

CONCLUSION

Understanding use, predictors of use, and learning needs is essential for developing knowledge translation initiatives to support clinical integration of VR/AVGs. Results of this first national survey will inform the creation of resources to support therapists in this field.

Virtual Reality for Pediatric Traumatic Brain Injury Rehabilitation: A Systematic Review

Objective. Pediatric traumatic brain injury (TBI) is associated with physical and psychobehavioral impairment in children. Effective rehabilitation programs postinjury are critical for children with TBI. Virtual reality (VR) has been increasingly adopted for brain injury rehabilitation. However, scientific synthesis is lacking in evaluating its effectiveness in pediatric TBI rehabilitation. This article aimed to conduct a systematic review on the effectiveness of VR-based pediatric TBI rehabilitation. Methods. A systematic literature search was conducted in PubMed, PsycInfo, SCOPUS, CENTRAL, BioMed Central, CiNAHL, and Web of Science through November 2015. Personal libraries and relevant references supplemented the search. Two authors independently reviewed the abstracts and/or full text of 5824 articles. Data extraction and qualitative synthesis was conducted along with quantitative assessment of research quality by 2 authors. Results. A positive impact was found for VR-based interventions on children's physical rehabilitation post-TBI. The quality of research evidence was moderate, which largely suffered from small samples, lack of immersive VR experience, and lack of focus on socioemotional outcomes post-TBI. Conclusions. The present review identified positive effects of VR interventions for pediatric TBI rehabilitation especially in physical outcomes. Future research should include larger samples and broader post-TBI outcomes in children using VR-based interventions.

Promoting Therapists' Use of Motor Learning Strategies within Virtual Reality-Based Stroke Rehabilitation

PURPOSE

Therapists use motor learning strategies (MLSs) to structure practice conditions within stroke rehabilitation. Virtual reality (VR)-based rehabilitation is an MLS-oriented stroke intervention, yet little support exists to assist therapists in integrating MLSs with VR system use.

METHOD

A pre-post design evaluated a knowledge translation (KT) intervention incorporating interactive e-learning and practice, in which 11 therapists learned how to integrate MLSs within VR-based therapy. Self-report and observer-rated outcome measures evaluated therapists' confidence, clinical reasoning and behaviour with respect to MLS use. A focus group captured therapists' perspectives on MLS use during VR-based therapy provision.

RESULTS

The intervention improved self-reported confidence about MLS use as measured by confidence ratings (p <0.001). Chart-Stimulated Recall indicated a moderate level of competency in therapists' clinical reasoning about MLSs following the intervention, with no changes following additional opportunities to use VR (p = .944). On the Motor Learning Strategy Rating Instrument, no behaviour change with respect to MLS use was noted (p = 0.092). Therapists favoured the strategy of transferring skills from VR to real-life tasks over employing a more comprehensive MLS approach.

CONCLUSION

The KT intervention improved therapists' confidence but did not have an effect on clinical reasoning or behaviour with regard to MLS use during VR-based therapy.

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 (19^th 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.

Investigating the Feasibility and Utility of Bedside Balance Technology Acutely After Pediatric Concussion: A Pilot Study

OBJECTIVE

To examine postural instability in children acutely after concussion, using the Wii Balance Board (WBB). We hypothesized that children with traumatic brain injury would have significantly worse balance relative to children without brain injury.

DESIGN

Prospective case-control pilot study.

SETTING

Emergency department of a tertiary urban pediatric hospital.

PARTICIPANTS

Cases were a convenience sample 11-16 years old who presented within 6 hours of sustaining concussion. Two controls, matched on gender, height, and age, were enrolled for each case that completed study procedures. Controls were children who presented for a minor complaint that was unlikely to affect balance.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

The participant's postural sway expressed as the displacement in centimeters of the center of pressure during a timed balance task. Balance testing was performed using 4 stances (single or double limb, eyes open or closed).

RESULTS

Three of the 17 (17.6%) cases were too dizzy to complete testing. One stance, double limbs eyes open, was significantly higher in cases versus controls (85.6 vs 64.3 cm, P = 0.04).

CONCLUSIONS

A simple test on the WBB consisting of a 2-legged standing balance task with eyes open discriminated children with concussion from non-head-injured controls. The low cost and feasibility of this device make it a potentially viable tool for assessing postural stability in children with concussion for both longitudinal research studies and clinical care.

CLINICAL RELEVANCE

These pilot data suggest that the WBB is an inexpensive tool that can be used on the sideline or in the outpatient setting to objectively identify and quantify postural instability.

Virtual Sensorimotor Balance Training for Children With Fetal Alcohol Spectrum Disorders: Feasibility Study

BACKGROUND

Diminished sensory adaptation has been associated with poor balance control for children with fetal alcohol spectrum disorders (FASD). A virtual reality system, Sensorimotor Training to Affect Balance, Engagement and Learning (STABEL), was developed to train sensory control for balance.

OBJECTIVES

The purpose of this study was to examine the STABEL system in children with FASD and children with typical development (TD) to (1) determine the feasibility of the STABEL system and (2) explore the immediate effects of the STABEL system on sensory attention and postural control.

DESIGN

This is a technical report with observational study data.

METHODS

Eleven children with FASD and 11 children with TD, aged 8 to 16 years, completed 30 minutes of STABEL training. The children answered questions about their experience using STABEL. Sensory attention and postural control were measured pre- and post-STABEL training with the Multimodal Balance Entrainment Response system and compared using repeated-measures analysis of variance.

RESULTS

All children engaged in game play and tolerated controlled sensory input during the STABEL protocol. Immediate effects post-STABEL training in both groups were increased postural sway velocity and some changes in entrainment gain. Children with FASD showed higher entrainment gain to vestibular stimuli. There were no significant changes in sensory attention fractions.

LIMITATIONS

The small sample size, dose of STABEL training, and exploratory statistical analyses are study limitations, but findings warrant larger systematic study to examine therapeutic effects.

CONCLUSIONS

Children completed the training protocol, demonstrating the feasibility of the STABEL system. Differences in postural sway velocity post-STABEL training may have been affected by fatigue, warranting further investigation. Limited immediate effects suggest more practice is needed to affect sensory attention; however, entrainment gain changes suggest the STABEL system provoked vestibular responses during balance practice.

A Wii Bit of Fun: A Novel Platform to Deliver Effective Balance Training to Older Adults

Background: Falls and fall-related injuries are symptomatic of an aging population. This study aimed to design, develop, and deliver a novel method of balance training, using an interactive game-based system to promote engagement, with the inclusion of older adults at both high and low risk of experiencing a fall.

Study Design: Eighty-two older adults (65 years of age and older) were recruited from sheltered accommodation and local activity groups. Forty volunteers were randomly selected and received 5 weeks of balance game training (5 males, 35 females; mean, 77.18 ± 6.59 years), whereas the remaining control participants recorded levels of physical activity (20 males, 22 females; mean, 76.62 ± 7.28 years). The effect of balance game training was measured on levels of functional balance and balance confidence in individuals with and without quantifiable balance impairments.

Results: Balance game training had a significant effect on levels of functional balance and balance confidence (P < 0.05). This was further demonstrated in participants who were deemed at high risk of falls. The overall pattern of results suggests the training program is effective and suitable for individuals at all levels of ability and may therefore play a role in reducing the risk of falls.

Conclusions: Commercial hardware can be modified to deliver engaging methods of effective balance assessment and training for the older population.

The Effects of Video Games on Cognition and Brain Structure: Potential Implications for Neuropsychiatric Disorders

Video games are now a ubiquitous form of entertainment that has occasionally attracted negative attention. Video games have also been used to test cognitive function, as therapeutic interventions for neuropsychiatric disorders, and to explore mechanisms of experience-dependent structural brain changes. Here, we review current research on video games published from January 2011 to April 2014 with a focus on studies relating to mental health, cognition, and brain imaging. Overall, there is evidence that specific types of video games can alter brain structure or improve certain aspects of cognitive functioning. Video games can also be useful as neuropsychological assessment tools. While research in this area is still at a very early stage, there are interesting results that encourage further work in this field, and hold promise for utilizing this technology as a powerful therapeutic and experimental tool.

Development and preliminary evaluation of a novel low cost VR-based upper limb stroke rehabilitation platform using Wii technology

PURPOSE

This paper proposes a novel system (using the Nintendo Wii remote) that offers customised, non-immersive, virtual reality-based, upper-limb stroke rehabilitation and reports on promising preliminary findings with stroke survivors.

METHOD

The system novelty lies in the high accuracy of the full kinematic tracking of the upper limb movement in real-time, offering strong personal connection between the stroke survivor and a virtual character when executing therapist prescribed adjustable exercises/games. It allows the therapist to monitor patient performance and to individually calibrate the system in terms of range of movement, speed and duration.

RESULTS

The system was tested for acceptability with three stroke survivors with differing levels of disability. Participants reported an overwhelming connection with the system and avatar. A two-week, single case study with a long-term stroke survivor showed positive changes in all four outcome measures employed, with the participant reporting better wrist control and greater functional use. Activities, which were deemed too challenging or too easy were associated with lower scores of enjoyment/motivation, highlighting the need for activities to be individually calibrated.

CONCLUSIONS

Given the preliminary findings, it would be beneficial to extend the case study in terms of duration and participants and to conduct an acceptability and feasibility study with community dwelling survivors. Implications for Rehabilitation Low-cost, off-the-shelf game sensors, such as the Nintendo Wii remote, are acceptable by stroke survivors as an add-on to upper limb stroke rehabilitation but have to be bespoked to provide high-fidelity and real-time kinematic tracking of the arm movement. Providing therapists with real-time and remote monitoring of the quality of the movement and not just the amount of practice, is imperative and most critical for getting a better understanding of each patient and administering the right amount and type of exercise. The ability to translate therapeutic arm movement into individually calibrated exercises and games, allows accommodation of the wide range of movement difficulties seen after stroke and the ability to adjust these activities (in terms of speed, range of movement and duration) will aid motivation and adherence - key issues in rehabilitation. With increasing pressures on resources and the move to more community-based rehabilitation, the proposed system has the potential for promoting the intensity of practice necessary for recovery in both community and acute settings.

Integrating virtual reality video games into practice: clinicians' experiences

The Nintendo Wii is a popular virtual reality (VR) video gaming system in rehabilitation practice and research. As evidence emerges related to its effectiveness as a physical therapy training method, clinicians require information about the pragmatics of its use in practice. The purpose of this descriptive qualitative study is to explore observations and insights from a sample of physical therapists (PTs) working with children with acquired brain injury regarding practical implications of using the Wii as a physical therapy intervention. Six PTs employed at a children's rehabilitation center participated in semi-structured interviews, which were transcribed and analyzed using content analysis. Two themes summarize the practical implications of Wii use: 1) technology meets clinical practice; and 2) onus is on the therapist. Therapists described both beneficial and challenging implications arising from the intersection of technology and practice, and reported the personal commitment required to orient oneself to the gaming system and capably implement this intervention. Findings include issues that may be relevant to professional development in a broader rehabilitation context, including suggestions for the content of educational initiatives and the need for institutional support from managers in the form of physical resources for VR implementation.

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.
