Delayed onset muscle soreness (DOMS) was the sensation of discomfort and stiffness in the muscle, often after taking part in unaccustomed physical activity. No universally accepted treatment exist. The aim of this study was to examine the influence of cryotherapy and intermittent compression on the delayed onset muscle soreness. Flexion elbow joint position and extension(Universal Goniometer). pain(Muscle Soreness Rating Scale) and mechanical pain threshold(Algometer) were measured before 30minutes DOMS was induced.The data were analyzed by measure of Mann-Whitney test and Kruskal-Wallis test. The result were as follow; 1. There were no significantly differences between groups or over time in relation to range of motion. 2. Muscle Soreness Rating was significantly high in cryotherapy and intermittent compression at 48, 72 hours after DOMS was induced(p<.05). 3. Mechanical pain threshold begin to increased at 24 hours and significantly in cryotherapy and intermittent compression groups at 48, 72 hours after DOMS was induced(p>.05). 4. A negative Correlation between muscle soreness rating scale and mechanical Pain threshold graphs at 24, 48, and 72 hours after exercise indicated in cryotherapy and intermittent compression groups.

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.

Mycoplasma pneumoniae is a common pathogen of community-acquired pneumonia. Mycoplasma pneumonia causes upper and lower respiratory tract symptoms in all age groups, with the highest attack rates in subjects 5 to 20 years old. In patients with mycoplasma pneumonia, the most common radiographic findings may be reticulonodular or interstitial infiltration, which have a predilection for the lower lobes. Findings that show lung collapse on a chest X-ray are very rare. We report a case of mycoplasma pneumonia that showed right upper lobe collapse.

A thymic carcinoma is a rare malignant neoplasm of the thymus epithelium, which can be distinguished from a benign or invasive thymoma. Contrary to a thymoma, the association of a thymic carcinoma and autoimmune disease is rare, with only a few cases having been reported. Herein, a case of thymic carcinoma diagnosed concurrently with systemic lupus erythematosus (SLE) is reported. A 49 year-old man presented at our clinic with myalgia. He was diagnosed with SLE, based on an oral ulcer, lymphopenia, and positive ANA and anti-Sm antibodies. Incidentally, a routine chest X-ray showed a large mediastinal mass. Pathological examination of the mediastinal mass revealed an undifferentiated thymic carcinoma, of WHO classification type C. Further work-up for staging showed multiple bone and lung metastases. With a palliative aim, he received systemic chemotherapy, but refused further chemotherapy after the $2^{nd}$ course. Currently, the patient has not been followed up since the chemotherapy.

Purpose: The purpose of the present study was to compare the effects of both general hold-relax techniques and hold-relax techniques using pumping on pain due to delayed muscle pain and on the range of motion (ROM) of joints. Methods: Thirty-nine young adult males and females were randomly assigned either to a hold-relax technique application group of 20 subjects or to a group of 19 subjects with hold-relax techniques applied using a pumping application. Tenderness thresholds, the ROM of joints, and pain intensities were measured on the biceps of the nondominant arm of the subjects in both groups before exercises were performed to induce delayed muscle pain. Tenderness thresholds were again measured 24hours, 48hours, and 72 hours after inducing delayed muscle pain. The relevant intervention methods were applied to the two groups after conducting the measurement at 48hours. As a statistical analysis method, repeated measure ANOVAs were conducted to examine the tenderness thresholds, ROMs of elbow joints, and pain intensities in the individual groups at the time points. Results: At 48 hours and 72 hours after application of the interventions, the general hold-relax technique application group showed greater changes in the tenderness thresholds, the ROMs of elbow joints, and the pain intensities than did the group applying hold-relax techniques using a pumping application (p>0.05). Conclusion: Based on the results of the present study, the application of hold-relax techniques is thought to have beneficial effects on pain resulting from delayed muscle pain and on limited ROMs of joints.

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.

The purpose of this study was to analyze sports injuries in athletes with disabilities during the 2015 National Games in Korea. We conducted a survey to assess sport injuries in 171 male athletes with disabilities who participated in this study. The shoulder was most frequently injured, followed by the fingers and low back. Contusions were the most common type of injury, and were usually caused by collisions with teammates or contact with equipment. Injuries often occur during enthusiastic play in both competition and practice sessions. Injured athletes are emergently treated with medicated spray and patch application by the head coach. Warm-up and cool-down exercises are recommended to prevent injury, and physical therapy is effective after an injury occurs. Based on these findings, an injury prevention training program and athletic trainers should be provided for athletes with disabilities to ensure appropriate care and rehabilitation.

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.
