Effect of High- and Low-Frequency Transcutaneous Electrical Nerve Stimulation on Angiogenesis and Myofibroblast Proliferation in Acute Excisional Wounds in Rat Skin

OBJECTIVE: This study evaluated the effects of high- (HF) and low-frequency (LF) transcutaneous electrical nerve stimulation on angiogenesis and myofibroblast proliferation in acute excisional wounds in rat skin. DESIGN: This was an experimental controlled and randomized study. PARTICIPANTS: An excisional wound was made on the back of 90 adult male EPM1-Wistar rats using an 8-mm punch. INTERVENTIONS: The animals were randomly assigned to the HF...
