Temporary Inactivation of Strong Muscle Sensation to Improve Rehabilitation Interventions in SCI

About this trial

This trial is enrolling individuals with chronic, motor incomplete cervical spinal cord injuries to test the effect of temporary numbing of non-paralyzed arm muscles during exercise of weak or partially paralyzed muscles. This technique, which is believed to induce functional recovery (via plasticity), has been shown to benefit individuals with stroke. Investigators want to see if numbing the stronger biceps can improve nerve activity the weaker triceps, thus improving hand dexterity and pinch strength in SCI. If included, participants will undergo a single exercise session with temporary numbing (using a topical cream).
