Comparing Mixed Reality and Physical Therapy to Improve Balance and Coordination in Adolescents With Spastic Diplegic Cerebral Palsy

erebral palsy (CP) is one of the most common neurological disorders affecting movement, balance, posture, and coordination in children and adolescents. Spastic diplegic cerebral palsy is characterized by increased muscle tone predominantly affecting the lower limbs, resulting in impaired balance, reduced coordination, and limitations in functional mobility. Conventional physical therapy is considered the standard rehabilitation approach; however, patient motivation and treatment adherence may limit its effectiveness.

Mixed Reality (MR) technology provides an immersive and interactive rehabilitation environment that combines virtual and real-world elements, enabling repetitive, task-oriented training with real-time feedback. Such interventions may enhance motor learning, neuroplasticity, patient engagement, and functional recovery. Despite promising evidence regarding immersive virtual reality interventions, limited randomized controlled trials have compared fully immersive Mixed Reality with conventional physical therapy in adolescents with spastic diplegic cerebral palsy.

This single-blinded randomized controlled trial aims to compare the effectiveness of fully immersive Mixed Reality combined with standard physical therapy versus standard physical therapy alone in improving balance and coordination among adolescents with spastic diplegic cerebral palsy. A total of 40 participants aged 10-19 years who meet the eligibility criteria will be recruited and randomly allocated into two equal groups. Group A will receive fully immersive Mixed Reality training using the Meta Quest Pro platform in combination with standardized physical therapy, while Group B will receive standardized physical therapy alone. Both groups will receive treatment three sessions per week for eight weeks.

Outcome assessments will be performed at baseline, after four weeks, and after completion of the eight-week intervention. Balance will be evaluated using the Pediatric Balance Scale (PBS), while coordination will be assessed using the Comprehensive Coordination Scale (CCS). The findings of this study will provide evidence regarding the effectiveness of fully immersive Mixed Reality as an adjunct to conventional physical therapy and may contribute to improving rehabilitation strategies for adolescents with spastic diplegic cerebral palsy.
