Home-based Spinal Cord Stimulation for Hand & Arm Function in MS

This is a pilot study designed to test the feasibility of in-home, non-invasive (transcutaneous, applied by surface electrodes over the skin) electrical spinal cord stimulation combined with exercises for restoring upper extremity sensorimotor function in adults with multiple sclerosis. Participants with multiple sclerosis and impaired upper extremity function will complete 8-weeks of hand/arm exercises combined with spinal cord stimulation performed at home with the help of a partner. The investigators hypothesize that: 1. in-home transcutaneous spinal cord stimulation combined with hand/arm exercises will be feasible and acceptable by participants 2. in-home transcutaneous spinal cord stimulation combined with hand/arm exercises will lead to improvements in upper extremity function after 8-weeks 3. in-home transcutaneous spinal cord stimulation combined with therapy will lead to improvements in symptoms related to quality of life (pain, spasticity, and bladder symptoms)
