Abstract

Purpose: This study examined the effect of EMG-stim related to the functional recovery of the upper extremity in chronic stroke patients with an intensive massed practice protocol. Methods: The subjects were assigned randomly to either the EMG-stim group (n=10) or sham treatment group (n=10). Both groups received conventional physical therapy, occupational therapy and FES, five times per week over a four week period. In the EMG-stim group, EMG-stim was applied to the hemiplegic wrist and finger extensors for 2 sessions for 30 minutes per day, 5 times per week over a 4 week period. As the pre- and the post-test, the following four motor tests were assessed as the function of the upper extremity clinical functional test: extensor digitorum strength test, Box and Block test, Fugl-Mayer Assessment, and Jebson-Taylor Hand Function Test. Results: In the Box and Block test and Fugl-Mayer Assessment, there were statistically significant differences between both groups as well as between pre- and post-test. The extensor digitorum and wrist extensor strength were similar in both groups. In the Jebson-Taylor Hand Function Test, there was a significant difference in simulated page turning but not in the other subtests. Conclusion: Intensive massed practice with EMG-stim intervention applied to the hemiplegic upper extremity is an effective therapeutic method for chronic stroke patients. However, a variety of intervention methods designed for stroke patients in clinical settings are needed.
