Abstract

Background. Somatosensory stimulation in the form of repetitive peripheral nerve stimulation (RPSS) is a promising strategy to improve motor function of the upper limb in chronic stroke. Home-based RPSS may be an alternative to hospital-based RPSS. Objectives. To investigate the feasibility and safety of an innovative program of home-based RPSS combined with motor training and to collect preliminary data on the efficacy of this program to enhance hand motor function in patients in the chronic phase after stroke. Methods. Twenty patients were randomized to either active or sham RPSS associated with daily motor training performed at home over 4 consecutive weeks. All the patients were able to perform tasks of the Jebsen-Taylor Test (JTT). The primary outcome measures were feasibility, evaluated by self-reported compliance with the intervention, and safety (adverse events). Secondary outcomes comprised improvements in hand function in the JTT after end of treatment and after a 4-month follow-up period. Results. There were no relevant adverse events. Compliance with RPSS and motor training was significantly greater in the active group than in the sham group. Upper extremity performance improved significantly more in the active group compared with the sham group at the end of treatment. This difference remained significant 4 months later, even when differences in compliance with motor training were considered. Conclusions. Home-based active RPSS associated with motor training was feasible, was safe, and led to long-lasting enhancement of paretic arm performance in the chronic phase after stroke for those who can perform the JTT. These results point to the need for an efficacy trial. (AU)
