The purpose of this study was to determine the effect of transcutaneous electrical nerve stimulation(TENS) and He-Ne laser at auricular point on delayed onset muscle soreness(DOMS). Twenty healthy adult males and females performed eccentric exercise of the elbow flexor. DOMS was induced in a standardised fashion in the nondominant elbow flexor of all subject by repeated eccentric exercise. Subject were assigned randomly to one of trees groups. Group 1 received TENS to the appropriate auricular point for biceps pain, Group 2 received laser to the appropriate auricular point for wrist pain, Group 3 received no treatment and served as controls. After exercise, treatments were applied at 24 hours and at 48 hours and at 72 hours after. Group 1 showed stastically significant increase(p<0.05) in pain threshold after treatment whereas the Group 2 and 3 did not. Group 1 showed a significant increase in pain threshold than Group 2. These results suggest that TENS has the capability to higher pain threshold but laser does not.

Background: This study aimed to investigate the effect of hold-relax and antagonist contraction (HR-AC) technique and Kinesio taping on pain changes in delayed-onset muscle soreness (DOMS) of 20's adults. Methods: Based on voluntary participation, 14 participants with induced-DOMS were randomly divided into control (non-treatment, n=7) and experiment group (HR-AC technique and kinesio taping, n=7). Measurement were used visual analogue scale (VAS), heart rate variability (HRV), and brain wave (alpha). There were 5 sets of the HR-AC technique application on the 5th day from the day of DOMS induction (rest for 30s between sets). Kinesio taping was applied to the same area after HR-AC. Results: The VAS showed significant changes according to the period and in the interaction between the period and the group (p<.01). HRV and alpha wave (Fp1) showed significant changes according to the period (p<.001). The analgesic effect was more rapid and continuous in the experimental group than in the control group. Conclusion: This study showed that the HR-AC technique and Kinesio taping are effective interventions for the management of pain and stress caused by DOMS.

본 연구에서는 신장성 수축운동에 의한 미세 근수축 요소 손강 이론(Morgan & Allen, 1999)을 검증하고자 신장성 수축운동의 범위에 따른 골격근의 기계학적 특성 변화에 주안점을 두어 실험 연구를 수행 하였다. 12명의 건강한 피험자가 최대 발목 족배굴곡근의 신장성 수축운동을 수행하였고, 운동수행 전에 최대 등척성 발목 족배굴곡 모멘트-각도 관계로부터 최적 발목 각도의 변화를 측정하였다. 신장성 수축운동 추 최적 발목 각도 변화는 신장성 수축운동의 범위와 상관없이 근육의 길이가 긴 쪽으로 변화를 가져왔다(4도, p<.05). 따라서 본 연구의 결과는 현재 많은 연구에서 거론되고 있는 신장성 수축에 의한 근력 저하 및 지연성 근육통의 촉발 기전인 신장성 수축에 의한 미세 근수축 요소 손강 이론의 부합하지 않으며, 이 현상을 설명할 새로운 이론 개발을 위한 후속연구의 필요성을 제기한다.

Purpose : The purpose of this study was to determine the effects of specific frequency and application timing of microcurrent (MC) on the mechanical property of muscle caused by delayed onset muscle soreness (DOMS). Methods : The subjects were 32 healthy adults with 8 subjects randomly assigned to four groups (I; 40 Hz MC while inducing DOMS, II; 40 Hz MC immediately after inducing DOMS, III; 284 Hz MC while inducing DOMS, IV; 284 Hz MC immediately after inducing DOMS). DOMS is applied to the biceps brachii muscle while MC was applied at an intensity of $300{\mu}A$ for 10 minutes. The mechanical properties of muscle were measured before and immediately after DOMS. Results : In terms of muscle tone, there were significant differences in interaction effects between time and groups. Regarding muscle elasticity and stiffness, there were no significant differences in interaction effects between time and groups but there were only significant differences in main effects based on time. Conclusion : The results indicated that 40 Hz MC had an effect on reducing muscle tone regardless of application timing. However, both 40 Hz and 284 Hz MC did not trigger changes in muscle elasticity and stiffness regardless of application timing.

The purpose of this study was to find the effects of the eccentric exercise induced delayed muscle soreness on proprioception, muscle strength, muscle fatigue, and muscle pain of the elbow flexor muscles. Thirty one healthy male subjects were participated in this study. Before resisted eccentric exercise of the elbow flexors and immediately and at 1, 3, 5, and 7 days post-exercise, pain threshold, proprioception, tension tracking, initial median frequency, and fatigue index were measured. Pain pressure threshold and visual analog scale (VAS) was used to measure muscle pain. Proprioception of the elbow joint was measured by using 3 dimension motion analysis system. Maximum isometric contraction was measured by using digital tensiometer. Electromyography and power spectrum analysis was used to measure initial median frequency (IMF) and fatigue index (FI). Immediately post-exercise, a significant decrease pain threshold was observed that continued to 5 days post-exercise. VAS score was significantly increased at 1 and 3 days post-exercise compared to that of immediately post-exercise. Maximum isometric contraction, IMF, tension tracking ability of the exercised elbow joint were significantly decreased at 1, 3, and 5 days post-exercise compared to that of pre-exercise. FI was significantly increased at 1 and 3 days post-exercise compared that of pre-exercise. Proprioception sense of exercised elbow joint was significantly decreased immediately and at 1, 3, and 5 days post-exercise compared to that of pre-exercise. Proprioception sense of the contralateral elbow joint was significantly decreased immediately post-exercise compared to that of pre-exercise. However, proprioception sense that was measured in close chain kinematic position was not significantly difference between pre-exercise and post-exercise. These results could be useful to determine the resume time for exercising and participating sports activities.

This study investigated the effects of triamcinolone acetonide by iontophoretic transdermal drug delivery on anti-inflammatory action into the human which had excentric exercise-induced delayed onset muscle soreness in the non-dominant arm. The degree of anti-inflammation was evaluated creatine posphokinase(CPK) by serum enzyme activity and subjective pain threshold by soreness muscle scale in clinical study. The results Were as follows; 1. In a subjective pain scale, all groups showed non-significant difference but, showed a tendency to decrease numerical value in human. 2. In the serum CPK level, iontophoresis group showed more significant reduction than other groups at 24, 48 and 72 hours. From the results, the iontophoresis with triamcinolone acetonide is more effective than using each groups. The continuous study is needed for many interesting issues of iontophoretic transdermal drug delivery in new future.

Purpose : Delayed onset muscle soreness(DOMS) is a common problem that can interfere with rehabilitation as well as activities of daily living. The purpose of this study was to compare the effect of both trascutaneous electrical nerve stimulation(TENS) Micro current(MC) and only normal Therapy on Delyed Onset Muscle Soreness(DOMS). Method : The Methods ten untrained and male volunteer subjects were randomly assigned to one of two treatment groups: 1) a group that received TENS (60Hz) MC($60{\mu}A$, 3pps) a control group that received no MC 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 24hours and 48hours. Subjects attended on two consecutive days for treatment and measurement of paining(visual analogue scale: VAS) and CK(Creatine kinase) on a daily basis. Measurements were taken after treatment. Results : 1) There were no significant differences between TENS and MENS by two-way repeated ANOVA. The Results that t-test for VAS revealed significant differences within TENS group. 3) The t-test for VAS, and Creatine Kinase of time revealed significant differences within MC group. Conclusion : These findings suggest that both TENS and MENS had effect on DOMS.
