The Effect of Digital Rehabilitation System With Wearable Multi-IMU (Inertial Measurement Unit) Sensors on Upper Limb Functions in Children With Brain Injury

Not Applicable

Completed

Interventions: Other: Conventional OT group
Device: digital rehabilitation system with wearable multi-IMU(inertial measurement unit) sensors (Rapael kids)

Brief Summary: This study was designed to establish the clinical evidence for effect of video-game based rehabilitation therapy system using IMU sensors as a game interface, newly-developed in Korea, on upper limb function of children with cerebral palsy. First, the investigators would compare the effect of video-game based rehabilitation therapy to conventional occupational therapy.

Detailed Description: * Purpose: to elucidate the effect of video-game based rehabilitation therapy system on upper limb function of children with cerebral palsy compared to conventional occupational therapy

* Subjects: total 30 children with cerebral palsy whose upper limb functions are impaired (all 30 children will receive the conventional occupational therapy, but 15 of these children will receive the additional video-game based rehabilitation therapy)

* Intervention: 4 weeks of therapy (6 days per week)

* Studies: functional MRI, computerized motion analysis, upper limb functional assessment (MUUL, ULPRS), ADL evaluation, cognitive evaluation

* Evaluation plan: 1) pre-intervention, 2) post-4 weeks of intervention, 3) 8 weeks after end of intervention

Primary Outcome Measures

Name	Time	Method
Total score of Melbourne Assessment of Unilateral Upper Limb Function	8 weeks	MUUL is the test of unilateral upper limb function is a validated and reliable tool for evaluating quality of upper limb movement in children with neurological conditions. It comprises 14 test items of reaching to, grasping, releasing and manipulating simple objects. Scoring is completed for the 30 item scores using a three, four or five point scale and the individually defined scoring criteria. The test will be done by occupational therapist. The total score of MUUL will be used for analysis.

Secondary Outcome Measures

Name	Time	Method
Total score of upper limb physician's rating scale (ULPRS)	8 week	ULPRS assess changes in the movement pattern, focusing on all 3 levels of the arm (palm, forearm, and elbow) to determine whether there is an isolated functional impairment, such as thumb in palm, restricted forearm supination, or a total flexion pattern with thumb in palm, wrist in flexion, forearm supinated, and elbow flexed. The score sheet includes 9 items, and 3-, 4-, and 5-point scales are used to score each component of movement tested. The total score of ULPRS will be used for analysis.
Kinematic data of computerized 3D motion analysis	8 week	3D motion analysis will be performed using a computerized motion analysis system (VICON MX-T10 System with 6 infrared cameras, Oxford Metrics Inc., Oxford, UK) to measure the kinematic data (angle of each joint) during the task of drinking from a cup. Kinematic data of forearm pronation or supination, wrist flexion or extension, ulnar deviation or radial deviation will be used for analysis.
Scaled scores of Pediatric Evaluation of Disability Inventory (PEDI-selfcare)	8 week	PEDI is a descriptive measure of a child's current functional performance. It measures both capability and performance of functional activities in three content domains: Self-care, Mobility, Social function. PEDI-selfcare section will be administered by occupational therapist. The Scaled scores of PEDI-selfcare will be used for analysis.
