 AIM 2: Using a single-blinded, randomized, controlled study design, to assess the ability of a 12-week at-home electrical stimulation gait training program to improve walking ability, standing posture, gait initiation, functional standing and stepping, and satisfaction with walking ability for a group of 10 children with spastic diplegia or hemiplegia CP as compared to a group of 10 children with spastic diplegia or hemiplegia CP who undergo a 12-week at-home gait training program without electrical stimulation.
