Neuromuscular Stimulation for Restoring Hand Movements

Evaluating Neuromuscular Stimulation for Restoring Hand Movements

The specific aim of this study is to evoke functional movement in the hand of both healthy individuals and individuals diagnosed with a stable cervical spinal cord injury with non-functional movement of the fingers. The primary purpose of this study is to determine the feasibility of achieving refined hand movements through electrical stimulation of the muscles within the forearm. It is believed that this study will be able to identify specific stimulation parameters and electrode spatial configurations responsible for various refined hand movements. After an eligible individual agrees to participate in this study, s/he will receive transcutaneous electrical stimulation on the forearm in order to evoke different hand and finger movements. The precision, specificity, and extent of these movements will be visually assessed. In order to better evaluate these movements, participants may also be asked to perform various functional tasks with their hand. The grip strength and evoked forces at the fingertips will also be measured using sensors. There will be up to 4 study sessions each week for up to 8 weeks, with each session lasting up to 4 hours. Upon completion of these study sessions, the individual's participation in the study is considered complete.

Device - Participants will receive neuromuscular electrical stimulation via an investigational (not FDA approved) neuromuscular stimulator.

The study involves the administration of various electrical pulses being delivered to muscles of the forearm from a neuromuscular stimulator in order to evoke different hand and finger movements. The grip strength and evoked forces at the fingertips will also be measured using sensors.
