Effects of electroacupuncture and transcutaneous electrical nerve stimulation on survival of musculocutaneous flap in rats.

The effects of electroacupuncture (EA) and transcutaneous electrical nerve stimulation (TENS) were investigated in the musculocutaneous flap in a rat model by measuring the surviving area and blood flow in the flap. Rats were divided into the control group, and groups treated with EA and TENS. Experimental results of this study show that flap survival area did not increase by EA but increased significantly by TENS treatment, and that blood flow in the periphery was significantly larger than that at the base.
