Improving Grasp Function in People with Sensorimotor Impairments by Combining Electrical Stimulation with a Robotic Hand Orthosis

About this trial

This trial is enrolling 20 individuals with chronically impaired motor and sensory functions of the hands to test the effect of a hand exoskeleton, Sensible-Exo, on grasping function. An exoskeleton is an externally worn powered robotic device to assist movement. Sensible-Exo is coupled with a sleeve that delivers both functional electrical stimulation (FES) and transcutaneous electrical nerve stimulation (TENS). FES is a technique that applies electrical stimulation through the skin to nerves to cause contraction of weakened or paralyzed muscles. TENS is a technique that delivers electrical stimulation through the skin to target specific nerves, aiming to increase touch sensation. If included, participants will receive up to 1 month of hand movement and sensation training with the aid of virtual reality. This will be followed by 1 month of regular Sensible-Exo use. Final testing will be performed 1 month later for a total of 3 months of participation.
