Active Comparator
Stimulation + Video Games
Video Games (no stimulation)
Contralaterally-controlled functional electrical stimulation (CCFES) enables patients with upper extremity hemiplegia to open their paretic hand by stimulating finger and thumb extensors with surface electrodes. CCFES is used during functional task practice and hand therapy video games to link motor intent with execution. Four intuitive and engaging games were developed to provide goal-oriented motor skill training, impairment-appropriate difficulty, and performance feedback that motivates iterative play and skill improvement.
Participants receive duration-matched, identical hand therapy video games and task practice therapy as the experiment arm, but do not receive CCFES to assist hand opening.
