The comparison of the Acupuncture-Like Transcutaneous Electrical Nerve Stimulation and Coventional Transcutaneous Electrical Nerve Stimulation in Crossover Effect

The purpose of this study was to compare acupuncture-like transcutaneous electrical nerve stimulation(ALTENS) with conventional transcutaneous electrical nerve stimulation(C-TENS) for crossover effect in healthy subjects. Forty subjects recieved ALTENS(20 persons), C-TENS (20 persons) to one upper extremity. Each technic was applied to the motor point of the wrist extensor muscle group for twenty-minutes. With the subject placed in supine the technics were applied at 80Hz, 2-10 mA(ALTENS) and 10Hz, 4-12 mA(C-TENS). Results revealed: (1) a significant difference between the pretreatment and posttreatment in each group(p<.05) (2) no significant difference between ALTENS and C-TENS(p>.05). In conclusion, there was no difference between ALTENS and C-TENS for crossover effect.
