Virtual Reality and Dual-Task Training for Cortical Plasticity in Children With Brachial Plexus Injury
Sponsor: Istanbul Aydın University
Summary
Brachial plexus birth injury (BPBI) is a condition that occurs when the nerves controlling the arm are injured during birth, leading to weakness, limited movement, and sensory problems. These motor difficulties may also affect cognitive processes related to movement. BPBI requires long-term follow-up and rehabilitation. This study will compare two treatment approaches in children with BPBI: * virtual reality (VR)-based exercises, and * motor-cognitive dual-task exercises. We will examine their effects on brain adaptation (cortical activation), muscle strength, joint motion, proprioception, and upper-limb function. Fourteen children aged 7-14 years will be randomly assigned to one of the two programs, each delivered for 12 weeks. Afterward, participants will continue a 9-month home program. Assessments will be conducted at baseline, after treatment, and at 12 months, including functional MRI (fMRI). This study will be the first to evaluate long-term brain changes and functional outcomes after these two rehabilitation approaches in children with BPBI.

Interventions
Conventional Physiotherapy Program
The conventional physiotherapy program includes educating the child and family about the condition and treatment goals, maintaining regular communication, planning sessions according to the child's abilities, motivating the child, and promoting active participation. Exercises are designed based on functional, daily-life, and play activities to maintain attention and engagement, following El-Shamy et al. (2017). Before each session, a 15-minute warm-up of shoulder internal rotation, pectoral, and elbow extension stretches will be performed (3 sets of 10 repetitions, 5-second hold).
Virtual Reality
Children in the VR group will perform conventional physiotherapy followed by 20 minutes of VR-based exercises using the Becure Leap Motion system. The games involve interactive tasks designed to improve wrist, hand, and upper-limb movements, coordination, and motor control, with progressively increasing difficulty levels. Sessions are supervised by the study physiotherapist.
Dual Task
Children in the dual-task group will perform exercises integrating conventional physiotherapy with cognitive-motor dual-task activities for a total of 45 minutes per session, following Wollesen et al. (2022). Cognitive tasks will be age- and ability-appropriate: younger children will perform basic memory and attention tasks, while older children will engage in more complex problem-solving, rapid decision-making, and language-based tasks. Task selection will consider the impact on motor performance, including movement quality, divided attention, reaction time, coordination, and executive functions, aiming to maximize motor-cognitive interaction. To maintain motivation, tasks will be gamified, competitive, offer choices based on personal interest, provide feedback, and reward achievements. Task difficulty will be adjusted individually.
