Abstract: Chae J. et al.: Neuromuscular Stimulation for upper extremity motor and functional recovery in acute hemiplegia. Stroke 29 (1998)975-979 Techniques available for the restoration of motor function after stroke remain unsatisfying. In particular upper extremity motor function recovery after hemiplegic stroke is often very poor. This study sought to assess the efficacy of neuromuscular electrical stimulation in enhancing motor and functional recovery post-stroke. Forty-six stroke survivors admitted to an inpatient unit were randomly assigned to receive either neuromuscular electrical stimulation or placebo. Subjects received treatment for one hour per day for a total of 15 sessions. Treatment was directed to the extensor digitorum communis and extensor carpi radialis muscles through surface electrodes. In the treatment group the stimulus pulse consisted of an asymmetric biphasic waveform with amplitude ranging between 0 to 60 mA pulse of 300 µs and frequency ranging between 25 and 50 Hz. The current amplitude and stimulus frequency were adjusted to the subject's comfort. Placebo treatment consisted of electrical stimulation that was directed away from muscle motor points and was applied above the sensory threshold but below the motor threshold. Outcomes were assessed using the upper extremity component of the Fugl-Meyer Motor Assessment and the selfcare component of the Functional Independence Measure (FIM). Measurements were taken at pre- and posttreatment and at four and 12 weeks after treatment. Twenty-eight subjects completed the study. Seven subjects in the ... schö
