ExaStim Upper Limb Home Use Clinical Validation Study

This is a multi-center, observational, single-arm, 6-week home study to evaluate the safety and efficacy of transcutaneous spinal cord stimulation via the ExaStim system for 4 consecutive weeks used in the home setting for individuals with traumatic spinal cord injury. The study consists of a baseline evaluation and 1-week training period (Week 0), a 4-week stimulation period (Weeks 1-4), and a follow-up visit (Week 5), for a total expected duration of participation for each subject of six weeks.

During the first week of the study, baseline measurements will be recorded for each subject and all eligible subjects and their caregivers will participate in a 1-week "Training Phase." Subsequently, subjects will perform activities of daily living and/or home exercises in conjunction with the ExaStim over a 4-week period in the home setting. In each session, subjects will receive stimulation while performing therapist-prescribed home exercises or activities of daily living. Stimulation must be utilized for a maximum of 300 -minutes per week and a minimum of 125-minutes per week. The time spent using stimulation during home sessions, and the number of sessions that patients perform each week, is flexible and is intended to facilitate the use of ExaStim within each participant's daily routine. Subjects and Clinicians will participate in weekly telehealth check-ins throughout the 4-week period in the home setting and will return to the clinic within one week of the final treatment to complete the final assessments in the study.
