지 연성 근육통 (delayed onset muscle soreness) 에대한 경피선경자극 (transcutaneous electrical nerve stimulation) 의 효과

Abstract

The pW1JOse of this study was to determine the effects of transcutaneous electric머 nervestimulation (TENS) on delayed onset muscle soreness (DOMS). Twenty males performedeccentric exercise of the elbow flexor. Subjects were random1y assigned to oneof three groups: 1) a group (nl=7) that received low frequency TENS (7 Hz), 2) agroup (n"=7) that received high frequency TENS (500 Hz), 3) a control group (n3=6)that received no treatment. DOMS was induced in a standardised fashion in the nondominant elbow flexor of all subjects by repeated eccentric exercise. Treatments wereapplied immediately folllowing exercise and again at 24 hours and at 48 hours after. Subjects attended on three consecutive days for treatment and measurement of elbow flexion, extension and resting angle(universa! goniometer), and pain (Visual Analogue Scale;V AS) on a daily basis. Measurements were taken after treatment. Analysis of resultsusing repeated measures analysis of variance (ANOV A) and post hoc tests were as fol•lows: 1) there were betweengroups differences in pain va!ue at 48 hours after (p<0.05),2) one-way ANOV A with repeated measurement for pain, resting angle, flexion angleand extension angle revealed significant differences within low frequency TENS group,3) one-way ANOV A with repeated measurement for flexion angle revealed significantdífference wíthin high frequency TENS group.
