Introduction: Several studies found that TENS is effective for reducing pain and
improving physical function. But it is still unclear that influencing of TENS for muscle
fatigue. The purpose of this study was to determine the effect of TENS on muscle
fatigue after isometric extension exercise of trunk.
Methods: To establish the muscle activity, healthy men were produced their maximum
isometric exertion 15 times and electromyography was recorded (Task I). And
continuing, subjects maintained the unsupported body as long as they could. After this,
subjects of study group were received TENS and subjects of control group were rested
for 5 minutes. After the intervention each group was produced their maximum
isometric exertion as same as Task 1 (Task II). VAS and muscle elasticity were
measured.
Results and Conclusions: The significant decreases of muscle activity of study group
were beginning later than in control group. And the fourth of task tends show a bigger
value of %VMA in comparison with the first of all muscles of Task I in both group and
in Task II in study group. However in Task II there were no tendencies in control
group. Therefore, we thought that TENS was influenced to nervous system
electronically for muscle fatigue.
