지연성 근육통에 대한 경피신경 전기자극과 미세전류 신경근 자극의 효과 비교

Abstract

Delayed onset muscle soreness(DOMS) is a common problem that can interfere with rehabilitation as well as activities of daily living. The propose of this study was to determine the effects of both transcutaneous electrical nerve stimulation(TENS)andmicrocurrent electrical neuromuscular stimulation (MENS) on DOMS. Twenty-seven untrained and male volunteer subjects were randomly assigned to one of three treatment groups: 1) a group that received TENS (7㎐), 2) MENS (60 ㎂, .3 pps) or 3) acontrolgroup that received no treatment. Subjects performed repeated eccentric exercise of the non-dominant forearm flexor muscle with submaximal intensity by the simply designed eccentric exercise devices. Treatments were applied after 24 hours and 48hours. Subjects attended on two consecutive days for treatment and measurement of elbow flexion, extension, resting angle (universal goniometer), and pain(visual analogue scale: VAS) on a daily basis. Measurements were taken after treatment. Analysis ofresults were as follows; 1) There were no significant differences between TENS and MENS by one-way repeated ANOVA, 2) The t-test for pain, resting, flexion and extension angle revealed significant differences within TENS group, 3) The t-test forrestingangle revealed significant differences within MENS group.
