Innovative Game-Aided Rehabilitation Platform for Rehabilitation of Balance in Children With Cerebral Palsy
Innovative Game-Aided Rehabilitation Platform for Rehabilitation of Balance in Children With Cerebral Palsy
The research project focuses on the evaluation of an engaging computer game-aided rehabilitation platform for use in rehabilitation of young children with cerebral palsy. The goal of this research program is to produce high quality therapeutic point-of-care approaches and cost-effective delivery systems leading to better long-term health outcomes. At present, the challenges entailed in providing therapy services continue to put identified children at risk of missing opportunities to maximize the neurodevelopmental capacities, sustain any behavioral recovery and prevent future complications.The program is grounded on the technological developments and on current research documenting the benefits of computer-aided learning tools, exercise gaming applications in rehabilitation and principles of adaptive learning and neuroplasticity. A randomized controlled trial (RCT) will be conducted to study the feasibility and effectiveness of a computer game-aided rehabilitation platform (CGR) for a repetitive task practice (RTP) protocol designed for training of balance in young children with Cerebral Palsy (CP).

Canada and India face a growing population of children with neurodevelopmental disabilities distributed across broad geographic regions. Cerebral palsy (CP) is the most common neurodevelopmental disability in childhood. The prevalence of CP in developing countries is estimated to be 5 to 10 times greater than in North America. Children with CP face a substantial amount of balance impairments which results in limitations of the mobility functions necessary for activities of daily living. The ability to perform functional tasks in sitting and standing while maintaining the balance is an important predictor of success in daily activities and participation in school, leisure and other aspects of community life.
There are many things to consider when developing therapy programs designed to improve dynamic balance skills for these affected children to maximize the neurodevelopmental capacities and to prevent the development of secondary disabilities. Intense repetitive task practice (RTP) such as, constraint-induced movement therapy is one of the few effective neuro-rehabilitative strategies shown to improve motor function in children with CP, with potential to overcome developmental difficulties. Constraint induced movement therapy consists of constraining the use of the unaffected limb to encourage use of the affected limb. However it is often difficult to engage children in therapy and sustain motivation to engage in intense RTP and achieve the therapy goals. Thus, there is a need for effective approaches and tools that motivate young children with CP to complete long-term neuro-rehabilitation programs and to provide developmental opportunities.
Digital media and gaming have received considerable interest from researchers and clinicians as a model for learning a broad range of complex tasks and facilitating the transfer of skills to daily life. These emerging rehabilitation technologies have the potential to improve clinical outcomes and child participation because these are engaging, motivating and now accessible. For this purpose a computer game-aided rehabilitation platform (CRP) has been developed. This approach combines motor exercises with fun games appropriate for children with neuro- developmental disorders. The approach is designed to provide engaging, high-quality, personalized therapy in the clinical rehabilitation setting.
Research Goal:
This research project focuses on the evaluation of an engaging exercise computer game-aided platform and embedded assessment tools for use in clinical practice. The program is grounded on the technological developments and on current research documenting the benefits of computer-aided learning tools, exercise gaming applications in rehabilitation and principles of adaptive learning and neuroplasticity. A pilot study to examine the feasibility and benefits of a computer-aided, game-aided repetitive task practice (RTP) program designed for training of dynamic balance skills in young children with CP will be conducted.
RESEARCH PROJECT OBJECTIVE 1
The CGR includes a designed rehabilitation assessment game which is capable of monitoring every child's performance during therapy. It quantifies motor skill parameters, as well as, visual-spatial skills and executive cognitive functions. It produces electronic records for these outcome measures and thus allows us to track change over time. It also provides timely feedback to child, parents and the therapist.
Objective: To evaluate the test-retest reliability and convergent validity of the assessment tool embedded in the game-aided rehabilitation platform. Specifically for dynamic balance in children aged 3-8 years (n= 50) diagnosed with CP. The new tool will be compared to commonly used outcome measures i.e. Peabody Developmental Motor Scale version 2 (PDMS-2) and Gross Motor Function Measure (GMFM). This will provide a reliable test protocol and valid measures that can accurately and quickly quantify dynamic balance control function independent of object-task type, for use in daily clinical practice and research. It is hypothesized that the performance measures of the game-based assessment tool would:
RESEARCH PROJECT OBJECTIVE 2
An feasibility randomized clinical trial will be conducted to examine recruitment, acceptability, compliance and therapy dosage of the CRP program and to estimate the treatment effect of the repetitive task practice game-aided exercise program on dynamic balance skills, transfers from sitting to standing, turning, stepping, and gait function in children aged 3-8 years (n= 50) diagnosed with CP. Preliminary estimation of treatment effects and the calculation of effect size and sample size for a full scale definitive RCT will be determined on the basis of pre and post scores of the primary outcome measures. Two groups of children will be examined, one group will receive the experimental game-aided balance training program and the other group will receive usual conventional balance training program. Each program would take 12 weeks, three therapy sessions per week. Using a process of randomization, every child will be assigned to either experimental or control group after the initial assessment and screening. Before the treatment sessions begin, after the end of 12 weeks, a clinician will conduct regular assessment sessions with the participant to mark the progress till date.
The feasibility of assessment tool embedded in the game-aided rehabilitation platform and also the usability, safety and appeal of the protocol will be examined. An estimation of effectiveness on this sample using mixed method Analysis of Variance for within (repeated measure) and between group effects will be observed.
RESEARCH PROJECT OBJECTIVE 3
It is important to develop evidence on quality and actual dosage of an intervention to be delivered to create a positive outcome on the transfer of skills to functional performance. Thus during each session the dosage of intervention will be determined by recording the duration, intensity and quality of the balance and mobility exercises delivered with this treatment model at each session. In turn the aim is to develop a dose-response relationship for clinical use of this CRP program in rehabilitation of children with CP.
STUDY DESIGN: Feasibility Randomized Clinical Trial
METHOD OF COLLECTION OF DATA:
Ethical clearance for the study will be obtained from the Institutional Ethical Committee of S. D. M. College of Medical Sciences and Hospital, Dharwad. Participants will be recruited by clinicians working in Outpatient Department of Physiotherapy, S.D.M. Hospital, Dharwad, Karnataka, India. Parents of the participants will be approached for consent to take part in the study, the study participants in experimental group will be asked to sit or stand (as per the screening result) on fixed and compliant surfaces and to use objects instrumented with the miniature motion mouse to play various therapeutic yet entertaining games while handling and moving the test therapeutic objects using bi-manual grip gradually progressing to head rotations (with the mouse mounted on a cap worn by the participant) and finally using trunk movements as a part of experimental therapy protocol. The head movements and trunk movements will increase the body sway and hence increase the balance cost of the exercises to result in improvement in balance control. The speed and the amount of head or trunk movements (i.e. balanced costs) will be graded by adjusting the difficulty level of game play. While performing CGR the children will be standing on a thin pressure mat (placed over fixed or compliant surface). This will allow us to record the information of Center of Foot Pressure (COP) displacement [body sway] while game-aided balance training intervention implementation. This information will be used to quantify the intensity and duration of each exercise (i.e. therapy dose) for objective 3.
