Abstract

|
Purpose: The purpose of this study was to determine the extent to which EMG biofeedback training plus exercise program
are associated with a reduction in the shoulder pain and the muscle tone of upper trapezius in manual wheelchair users
with spinal cord injury.
Methods: Exercise group (N=12) was instructed to do stretching and strengthening exercise to alleviateshoulder pain for 8-week, 50 minutes/day, 5 days/week. EMG biofeedback training group (N=12) was assigned to do the same program plus EMG biofeedback training to induce muscle relaxation. The level of pain was measured by WUSPI, and Myoton®PRO was utilized to measure the changes in tone, stiffness and elasticity of the upper trapezius.
Results: Both of experimental and control groups were effective for shoulder pain and muscle tone. However, in
comparison between groups, EMG biofeedback training group showed a statistically significant difference in reduction of
the shoulder pain and in muscle stiffness as compared with exercise group (p<.05).
Conclusions: EMG biofeedback training when combined with exercise program appear to show positive effects in the shoulder pain reduction.
