Effect of transcutaneous electrical nerve stimulation on nerve excitation between dominant and nondominant forearm.

ABSTRACT

The aim of the present study was to determine the effect of transcutaneous electrical nerve stimulation [TENS] on nerve excitation threshold [sensory, motor and pain threshold] between dominant and non-dominant forearm. Twenty-five healthy male volunteers ranged in age from 18 to 24 years participated in this study. Conventional type TENS [100 Hz frequency, 100 microseconds pulse duration] was applied over the median nerve on both forearms in all subjects. The intensity in milliamperes was recoded at threshold on both forearms. The results revealed insignificant differences in the excitation threshold between the two forearms. It was postulated that on the application of 100 Hz TENS, there was no alteration in current intensity to stimulate sensory, motor and pain threshold between dominant and non-dominant forearm
