Purpose: The purpose of this study to investigate the effect of TENS and electroacupuncture (EA) on injured muscle recovery and to compare the difference between TENS and EA.
Methods: 18 S-D rats were produced surgically for crush injury on Extensor digitorum. TENS and EA stimulation were applied on acu-point that Zusanli (ST36) and Taijun (Liv3) of each hindlimb as approximitely 2Hz for 15 minutes. The rats were sacrificed on 1, 3, 7 post operation day, and the spinal level was immunohistochmical stainied.
Results: The expression of NT-3 on the spinal level related with injured muscle between Ex-1 group and Ex-2, there is no significant difference. But between Con and Ex-1/Ex-2, there was little difference. In the same indivudual, we confirmed more NT-3 expression on the same side of injured muscle than on another side of gray matter in posterior horn.
Conclusion: There is no difference, which is more effective to recover of injured muscle, between EA and TENS on injured muscle.
