Background: This study was designed to identify the effect of the taping on the forward head posture during computer work. Methods: Twenty healthy adults were statistically assigned into 2 groups, the taping group (n=10) and the control group (n=10). In order to induce delayed onset muscle soreness (DOMS), twenty subjects performed isometric exercise of the neck on Bobath table for 20 minutes. During the experiment, subjects in taping group were attached Kinesio-tape on their upper trapezius. By using 2-D motion analysis, measurements were taken before taping, at 24 hour, 48 hour, and 72 hour after inducing DOMS. The effects of taping were evaluated by the angle of the head. Results: The results of this study were as follows; 1) There was no significant difference between the taping group and the control group (p>.05). 2) The control group had no significance, but the taping group shown a significance on the angle of head during computer work (p<.01). The interaction of group x period also shown a significance (p<.01). Conclusion: From these result, it was revealed that the taping therapy on upper trapezius could improve the angle of head during computer work.
The purpose of this study was to determine the effects of transcutaneous electrical nerve stimulation(TENS) on delayed onset muscle soreness(DOMS). Twenty males performed eccentric exercise of the elbow flexor. Subjects were randomly assigned to one of three groups: 1) a group ($n_1$=7) that received low frequency TENS (7 Hz), 2) a group ($n_2$=7) that received high frequency TENS (500 Hz), 3) a control group ($n_3$=6) that received no treatment. DOMS was induced in a standardised fashion in the non-dominant elbow flexor of all subjects by repeated eccentric exercise. Treatments were applied immediately following 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(universal goniometer), and pain(Visual Analogue Scale; VAS) on a daily basis. Measurements were taken after treatment. Analysis of results using repeated measures analysis of variance(ANOVA) and post hoc tests were as follows: 1) there were between groups differences in pain value at 48 hours after (p<0.05), 2) one-way ANOVA with repeated measurement for pain, resting angle, flexion angle and extension angle revealed significant differences within low frequency TENS group, 3) one-way ANOVA with repeated measurement for flexion angle revealed significant difference within high frequency TENS group.
Fluorescence properties and carbohydrate content were investigated using ultrafiltrated size fractions of dissolved organic matters (DOM) originated from different sources. The materials included a treated sewage, an algal organic matter, and a soil leachate, all of which are major constituents of dissolved organic matter in a typical urban river. Four different size fractions were separated from the three sources of each DOM. The size distribution demonstrated that a higher molecular weight fraction was more present in soil leachate compared to two other source DOMs. A higher content of carbohydrates was observed in the following order - algal DOM > treated sewage > soil leachate. A wide range of specific UV absorbance was observed from size fractions of a single source DOM, indicating that aromatic carbon structures are heterogeneously distributed within one source of DOM. The structural heterogeneity was the most pronounced for the soil leachate. The fluorescence index ($F_{450}/F_{500}$) of the treated sewage was similar to that (2.0) typically obtained from autochthonous DOM, suggesting that the treated sewage exhibited autochthonous organic matter-like properties. No protein-like fluorescence intensities were observed for all of the soil leachate size fractions whereas they were observed with two other source DOMs. Based upon the fluorescence peak ratios from fluorescence excitation-emission matrix (EEM), two discrimination indices could be suggested to distinguish three different source DOMs. It is expected that the suggested discrimination indices will be useful to predict the sources of DOM in a typical urban river affected by treated sewage.
Background: The purpose of this study was to investigate the effects of HBOT (hyperbaric oxygen therapy) on the pain, ROM (range of motion) and muscle fatigue recovery of DOMS (delayed onset muscle soreness). Design: Randomized Controlled Trial. Methods: Twenty-six subjects who are student in their 20s at a university participated in this study, these subjects were assigned into two groups, a control group (n=12) and an experiment group (n=14). The subjects in experimental group were intervened by HBOT (40 minutes, 1.3 ATA), while ones on control group weren't by any intervention after induced DOMS. Results: First, in the comparison of VAS (visual analog scale), there were significant variations with the period (p<0.001), interaction of period (p<0.05) and group (p<0.05). In the comparison of PPT (pressure pain threshold), there were significant variations with the period (p<0.001) and interaction of period (p<0.05). Second, in the comparison of ROM, there were significant variations with the period (p<0.001), interaction of period (p<0.001) and group (p<0.01). Third, in the comparison of CK (creatine kinase) and LDH (lactate dehydrogenase), there no signigicant variations with all measure variables. Conclusion: The above results indicated that HBOT were effective to decrease the pain and improve the ROM in DOMS. Also the statistical significant variations of blood factors of muscle fatigue were not found in this.
Objective: The purpose of this study was to investigate the effects of eccentric contraction training (ECT) and concentric contraction training (CCT) on the muscle thickness (MT), muscle strength (MS) and delayed onset of muscle soreness (DOMS) of the lower extremities in persons with chronic stroke. Design: Randomized controlled trial. Methods: Thirty persons with chronic stroke were randomly assigned to the ECT or the CCT group. The ECT was performed in a specially designed system of eccentric contraction of both legs and, the CCT was performed using a traditional stepper system for concentric contraction of both legs. The training was performed for 30 min/times, 3 times/wk for 6 weeks. Rehabilitation ultrasound imaging was used to measure MT of the vastus medialis/lateralis (VL), and soleus (SOL), a digital muscle tester was used to measure MS, and a visual analog scale was used to assess DOMS. Results: In the ECT group, MT was significantly improved except for SOL resting (p<0.01). In the CCT group, the MT was significantly improved except for VL contraction (p<0.05). The MS was significantly improved in both groups, especially in the ECT group (p<0.01). In the ECT group, muscle soreness was highest in the first week after training but gradually decreased, and in the CCT group, it was highest in the second week of training but gradually decreased (p<0.01). Conclusions: ECT can improve lower limb MT, MS, and DOMS of chronic stroke survivors. Therefore, it is recommended that ECT be used in the rehabilitation of persons with chronic stroke.

This study examined the effect of VT(Vibration Training) on the symptoms of DOMS (Delayed-Onset Muscle Soreness) before induced by eccentric exercise of the left leg triceps surae. Twenty one healthy adult men and women who had not participated in a regular exercise program for the lower extremities were assigned to one of two experimental groups: vibration training group, Control group. We measured the VAS(Visual Analogue Scale), ankle plantar flexor strength, triceps surae circumference, CK(Creatine Kinase) before and after exercise and 24, 48 and 72 hours after eccentric exercise. After inducing DOMS, VAS showed significant differences between groups at a point of time 48 hours, and showed significant differences within groups in accordance with the time of measurement(p<.05). Plantar flexor strength of groups with VT did not show significant difference between groups but, showed significant differences within groups in accordance with the time of measurement(p<.05). Triceps surae circumference of groups with VT did not show significant difference between groups but, showed significant differences within groups in accordance with the time of measurement(p<.05). CK of groups with VT did not show significant difference between groups but, showed significant differences within groups in accordance with the time of measurement(p<.05). As a result of the study, VT prior to eccentric exercise is effective to inhibit pain. So, this method can be suggested to prevent DOMS in doing an unfamiliar activites.
The purpose of this study is to find out the effectiveness of the therapeutic sports massage(TSM) applied to the patients with delayed onset muscle soreness(DOMS) by measuring, assessing and analyzing the changes in intensity and unpleasantness of muscle pains before and after TSM. In the therapeutic sports massage program, such methods as effleurage, petrissage and deep transverse friction were selected as traditional massage treatments frequently used for muscles with pain and spasm. Effleurage and petrissage were applied for 20 minutes in total before and after deep transverse friction treatment. After TSM, the McGill pain questionnaire word list(MPQWL), verbal rating scale(VRS), visual analogue scale(VAS) were used to measure the degree of the pain on the patients. The major findings from this study are as follows; 1. The surveyed patients range from 15 to 63 in age, with highest numbers of 18(37.50%) registered in the twenties and next ones of 14(29.17%) in the thirties. Divided by sex, 27 are men and 21 are women totalling 48 with average age of 25.7. 2. There was significant decrease in the numerical values of VAS & VRS and MPQWL immediately after TSM(p<.05). There was also significant decrease in the numerical values of MPQWL, VRS and VAS after the 2nd, 3rd, 4th, 5th TSM(p<.05). 3. There was significant decrease in the intensity and unpleasantness of pains after TSM(p<.05). 4. From the analysis into chronological changes in the intensity and unpleasantness of pains before and after TSM with ANOVA, it became evident that the longer the period of treatment was, the higher the pains decreases drastically, while significant difference was shown in the intensity and unpleasantness of pains(p<.05). Summed up, it can be generally concluded that TSM is an effective treatment to rid the patients with DOMS of pains safely and promptly.
The purpose of this paper was to enable patients, who suffer from muscle damage. to return to their normal activities as soon as possible. With this in mind. this experiment was carried out to make an analysis of a variety of ingredients subjected to changes when muscle damage or muscle soreness was treated with aceclofenac, NSAID, and to find out what effect the anti-inflammation produced in relation to such symptoms. It made use of male rats (Sprague-Dawely) as subjects. It carried out two kinds of experiments: one was a preliminary experiment from March 15, 2001 to March 20, 2001 and the other was a main experiment from March 30, 2001 to April 15, 2001. Each group was composed of five rats. In case of DOMS. it worked with eight male adults from April 20. 2001 to April 30, 2001. It have come up with the following conclusions: 1. The leucocytes and erythrocytes of the experiment group were decreasing with the lapse of time in comparison with those of the contrast group. And a decrease in the number of hemoglobin had remarkably statistic significance (P<0.05). 2. Neutrophil, Lymphocyte and Monocyte decreased in 36, 24, 12 and 24 hours, respectively, which means that they had a significant difference(P<0.05). 3. CPK and LDH were reduced remarkably through the whole time slot in comparison with the contrast group, and had statistic significance(P<0.05). The findings above show that anti-inflammations cure bruises or damage or myalgia in a shorter period of time than the normal recovery of other treatment.
Objectives : The aim of this study was to investigate difference of the effects of transcutaneous electrical nerve stimulation(TENS) with different frequencies in participants having delayed onset muscle soreness(DOMS). Methods : We recruited 36 healthy participants, but 3 of them were dropped out. They were randomly divided into 3groups : 3 Hz TENS(n=11), 100 Hz TENS(n=11) and sham TENS(n=11). DOMS of the both triceps surae muscle induced by repetitive concentric, ecentric exercise. The result measurements were pain perception(visual analogue scale, VAS), mechanical pain threshold(MPT) by pressure algometer, electrical contraction and fatigue by surface electromyography. The measurements were on first visit, before and after treatment except first. This study was prospective, randomized, controlled, single-blinded trial. Results : In 100 Hz TENS group, VAS was significantly decreased during whole session compared with 3 Hz and control group, and after each treatment, too. In 3 Hz TENS group, VAS was significantly decreased during whole session compared with control group, and after 2nd, 3rd treatment, too. In 100 Hz TENS group, MPT increased the most among 3 groups during whole session and after 1st treatment, but there were no statistical significances. Conclusions : Both 3 Hz and 100 Hz TENS improved delayed onset muscle soreness, but 100 Hz TENS group is more effective than 3 Hz TENS group.

The aim of this study was to develop a Pulsed Magnetic Fields(PMFs) system which can produce effects locally and simulate muscular tissues equally. To evaluate the PMFs system we caused DOMS(Delayed Onset Muscle Soreness) to subjects in biceps of the arm. Then, we stimulated acupoint HT2 using PMFs(20 minutes) and TEAS(20 minutes) for 2 days. The other subjects did not stimulate. Then we checked body surface temperature in biceps of the arm. All subjects had an asymmetrical body surface temperature in biceps after exercise(Non-stimulation group=$2.00{\pm}1.16^{\circ}C$, TEAS group=$1.73{\pm}0.52^{\circ}C$, PMFs group=$1.48{\pm}0.51^{\circ}C$). After 1st stimulation all subjects had decreased temperature differences(Non-stimulation group=$1.37{\pm}0.71^{\circ}C$, TEAS group=$1.08{\pm}0.43^{\circ}C$, PMFs group=$1.23{\pm}0.15^{\circ}C$). PMFs group had a symmetry body surface temperature after 24 hours($0.05{\pm}0.06^{\circ}C$) and TEAS group had that after 48 hours($0.1{\pm}0.08^{\circ}C$). Non-stimulation group did not recovery after 48 hours($0.37{\pm}0.06^{\circ}C$). Therefore, PMFs on acupoint had an therapeutic effect in DOMS.
