OBJECTIVE: To investigate the effectiveness of repetitive facilitative exercise (RFE) under surface neuromuscular electrical stimulation (NMES) in patients with post-stroke hemiplegia. METHODS: This randomized, controlled, observer-blinded, pilot trial randomized 27 adults with severe arm impairment (Fugl-Meyer Arm scale (FMA) < 20) due to stroke of 3 to 13 weeks duration into three groups and provided treatment on a 4-week, 40 minutes/day, 5 days/week schedule. The RFE-under-NMES group were given 100 to 150 repetitions of standardized movements of shoulder, elbow and wrist joints of their affected arm with concurrent low-amplitude NMES for each corresponding musculature. The RFE group was given the same exercise regimen but without NMES. The control group was treated with a conventional arm rehabilitation programme without NMES. FMA was assessed at baseline and 4 weeks. RESULTS: All 27 participants (nine in each group) completed the trial. At 4 weeks, the RFE-under-NMES group evidenced significantly greater improvement compared with the control group on the FMA (p = 0.003), but not with the RFE group (p = 0.092). The RFE group showed improvement compared with the control group, but it was not significant (p = 0.199). CONCLUSIONS: RFE under NMES is feasible in clinical settings and may be more effective than conventional rehabilitation in lessening arm impairment after sub-acute stroke.
