초록

Lateral epicondylitis is caused by repeated use of the wrist, which causes inflammation and pain in the wrist extensor and tendon of the humerus. Delayed onset muscle soreness (DOMS) caused by repetitive resistance exercise affects the tendons connected in series with the muscle, leading to lateral epicondylitis. Although microcurrent stimulation has been suggested as a possible treatment for tendinitis, there are insufficient studies on specific variables such as frequency. In this study, 15 healthy adult males and females developed DOMS in the wrist extensor and tendon in the humerus. The experimental group consisted of a low frequency group applying 20 Hz and a high frequency group applying 100 Hz according to the micro-current frequency. Each subject underwent an experiment for 5 days after DOMS, and the recovery rates were compared by measuring AROM, GPT, MST, PPT, and VAS. As a result, the 20 Hz group showed significant changes in AROM, MST, and VAS compared to the control group on the 4th day, and the recovery rate was also higher than that of the 100 Hz group. On the 5th day, recovery rate of 100 Hz group was higher than 20 Hz in AROM and PPT, and MST showed higher recovery rate than 20 Hz group, but there was no significant difference. These results indicate that microcurrent stimulation is effective for the treatment of delayed myalgia and tendon inflammation and that the 100 Hz group has faster recovery than the 20 Hz group.
