Abstract

Objectives The purpose of this study was to evaluate the most effective stimulating electrode in Microcurrent electrical neuromuscular stimulation (MENS) for pain relief, and to apply to the treatment of Delayed onset muscle soreness (DOMS). Methods We included 45 participants who met the inclusion criteria. DOMS of both Triceps Surae Muscles were experimentally induced through eccentric contractions. 24-hours after induction of DOMS, who scored more than 40 mm in visual analogue scale (VAS) were randomly assigned into three groups (n=44). In 15 of them, needle electrodes were inserted into BL57, BL56. In 15 of them, surface electrodes were applied on the same points and the others were treated with manual acupuncture. The effects of pain relief were assessed by visual analogue scale (VAS), mechanical pain threshold (MPT), surface electromyography (SEMG). Results In VAS, group comparison had no significant difference after all treatments had done. The difference in VAS between the time before the treatment was started (Day 2) and after all treatments were completed was greater in Acupuncture group than that of needle-electrode group. In MPT, there was no significant difference among groups. Electrical contraction decreased significantly at 2nd before-after treatment comparison in needle-electrode MENS group. But fatigue scores were not significantly different between groups. Conclusions The results suggest that the types of electrodes has no significant effect on microcurrent therapy in DOMS.
