Effect of Using an Object Handling Serious Game on Upper Limb Rehabilitation for Children with Neurological Disorders

Cerebral palsy, and more broadly neurological disorders, can lead to significant motor impairments that impact individuals' daily lives. To address these limitations, the French National Authority for Health has issued recommendations for rehabilitative care, highlighting intensive training programs, physical activity, and interactive computer games. Scientific literature has also demonstrated the benefits of therapies that incorporate repetition. In this study, the investigators aimed to train patients in producing grasp-and-release movements, and more broadly \*reach-to-grasp\* actions, in a manner intensified by movement repetition. To mitigate the boredom inherent to such repetitive tasks, the invesigators developed a device resembling a serious game, equipped with software, a modular physical platform, and two instrumented figurines designed to interact with the software. Intensive therapy through repetitive movements, supported by the engaging nature of serious games, is expected to improve the manual skills of children with neurological disorders causing motor impairments. To test this hypothesis, a cohort of 5 to 10 children aged 4 to 17 years with neurological disorders causing motor impairments will be invited to participate in the protocol. Participants will first undergo a baseline assessment, which will include repeated measurements of their score on the \*Box and Blocks Test\* and the active range of motion (AROM) of the wrist in extension and supination. An \*Assisting Hand Assessment (AHA)\* test will also be conducted. Following this, a 4-week intervention will be implemented, consisting of three 40-minute sessions per week. During these sessions, the child will play the game and complete the \*Box and Blocks Test\* as well as active range of motion assessments. In total, approximately 4 hours of gameplay is estimated over the course of the intervention, which will conclude with a repeat of the AHA test. A follow-up assessment will take place two months after the intervention's end, with a single measurement of the three parameters (\*Box and Blocks Test\*, AROM, and AHA).
