Safety and Effectiveness of Spatial StimelMD (SSMD) in Subjects With Upper Limb Neuromotor Impairments

Overview

This is a multicenter, randomized, controlled clinical study evaluating the safety and effectiveness of the Spatial StimelMD (SSMD) device for upper-limb neuromotor rehabilitation in adults with impairment following stroke or traumatic brain injury (TBI). Participants will be randomized to receive either SSMD therapy plus standard rehabilitation care or standard functional electrical stimulation (FES) plus standard care. Subjects will complete approximately 25 supervised treatment sessions over 5-6 weeks, with assessments at baseline, mid-treatment, post-treatment (primary endpoint), and a 1-month follow-up. The primary effectiveness endpoint is improvement in upper-limb motor function measured by the Fugl-Meyer Upper Extremity (FMA-UE) assessment. Secondary outcomes include movement metrics, EMG signal strength, functional independence, usability measures, and adverse event monitoring. The study plans to enroll approximately 150 subjects to achieve 126 completers, across 2-6 clinical sites.

CP-SSMD-01 is a multicenter, randomized, controlled clinical study designed to evaluate the safety and effectiveness of the Spatial StimelMD (SSMD) device for upper-limb neuromotor rehabilitation in adults with impairment following stroke or traumatic brain injury (TBI). The study compares SSMD therapy plus standard rehabilitation care to standard functional electrical stimulation (FES) plus standard care. Participants will complete approximately 25 supervised treatment sessions over a 5-6 week period. Subjects will undergo evaluations at baseline, mid-treatment, post-treatment (the primary endpoint), and a follow-up visit approximately one month after completing therapy. The primary outcome measure is improvement in upper-limb motor function assessed using the Fugl-Meyer Assessment for the Upper Extremity (FMA-UE). Secondary outcomes include additional measures of motor performance and movement quality, EMG-based muscle activation metrics, functional independence outcomes, usability assessments, and safety monitoring through adverse event reporting. The study aims to enroll approximately 150 participants, with an expected 126 completing the full protocol, across 2-6 clinical sites. This trial is intended to generate clinical evidence on whether SSMD therapy can support meaningful upper-limb motor recovery compared with a standard stimulation-based rehabilitation approach in individuals affected by stroke or TBI.
