Feasibility study of a combined treatment of electromyography-triggered neuromuscular stimulation and mirror therapy in stroke patients: A randomized crossover trial

摘要

BACKGROUND: Mirror therapy (MT) and electromyography-triggered neuromuscular stimulation (ETMS) are both effective treatments for impaired upper limbs following stroke. A combination of these two treatments (ETMS-MT) may result in greater gain than either treatment alone. OBJECTIVES: The feasibility and possible effects of ETMS-MT upon upper extremity function were investigated in stroke patients. METHODS: Thirteen post-acute stroke patients were randomly assigned to an immediate ETMS-MT group or a delayed ETMS-MT group and then underwent an 8-week training program. The immediate ETMS-MT group received ETMS-MT in addition to physical and occupational therapy (PT+OT) for 4 weeks. They then received only PT+OT for the next 4 weeks. In the delayed ETMS-MT group, interventions were provided in the reverse order. The main outcome measure was the Fugl-Meyer Assessment (FMA). RESULTS: The immediate ETMS-MT group showed significantly greater gain in FMA in the first 4 weeks. The delayed ETMS-MT group showed significantly greater gain in active range of motion during the latter 4 weeks. No adverse effects were reported following ETMS-MT. CONCLUSION: ETMS-MT might be as effective as independent MT or ETMS without causing any side effects. Future research should focus upon the direct comparisons between independent and combined interventions.
