Most types of robot-assisted training (RT) have been used in Cerebral Palsy (CP) patients only focus on proximal upper extremity. Few of study investigated the effect of distal upper extremity training. Pediatric CP patients (N.=7) participated the RT sessions for 6 weeks (12 60-min sessions 2 times a week). Performance was assessed at 3 time points (pretest, posttest, and 1-month follow-up). RT significantly improved in body structure and function domains: FMA-UE scores (P=0.002). On electromyography, significant improvements in the mean brachioradialis muscle amplitude (P=0.015) and electrical agonist-antagonist muscle ratio (P=0.041) in the 1-inch cube-grasping task. The effects were maintained after 1 month. RT using a Gloreha device which focuses on the distal part of the upper limb benefit on body structure and function, including upper-extremity motor function, brachioradialis muscle recruitment, and coordination in children with cerebral palsy.
