본 연구는 미세전류자극이 비만인의 체성분과 혈중지질성분의 변화에 미치는 효과를 규명하고, 복합운동의 효과와 비교함으로써 효과적인 체형 관리 방안으로서 미세전류자극의 유용성을 밝히고자 하였 다. 체지방율 30% 이상인 여대생 30명을 통제집단, 복합운동집단, 미세전류자극집단으로 분류하였으며, 각 집단 별 4주간의 처치 전후 체중, 체지방율, 허리 둘레 등의 체성분 요인과 TG, TC, apolipoprotein 등의 혈중지질성분을 측정한 자료를 분석하여 다음과 같은 결과를 얻었다. 통제집단에서는 모든 측정 항목에서 통계적으로 유의한 차이가 나타나지 않은 반면 복합운동 집단에서는 허리둘레와 TC가 유의하게 감소한 것 으로 나타났고, 미세전류자극 집단에서는 체중, 체지방율, 허리둘레, apolipoprotein 등이 유의하게 감소한 것으로 나타났다. 이러한 연구결과를 고려할 때 미세전류 자극은 비만인의 체성분과 혈중지질성분을 개선 시켜 건강한 신체를 갖도록 하는데 효과적인 중재 방안으로 제안할 수 있다.

Osteoarthritis is a degenerative joint disease and is led to physical disability. Yet the development of effective disease-modifying treatments has lagged. In this study, I examined the effect of physical therapeutic intervention through microcurrent stimulation and attempt to find which degree of intensity, either 25 or 500 with a regular 5 pps pulse, is more effective in the osteoarthritis. Osteoarthritis was induced with a mixture of 2% carrageenan and 2% kaolin in 26 male Sprague-Dawley rats. The mixture (0.1 ) was injected into the intra-articular capsule of knee joint once a week for three weeks. Five animals did not show degenerative changes by radiological findings and excluded in the following experiment. Osteoarthritic animals were randomly divided into 3 groups (, , =7/each): untreated, treated with 25 , treated with 500 . All experimental groups received microcurrent stimulation for four weeks (15 min/day, 5 days/week). The ethological inspection of foot print analysis on the walking corridor was accomplished every week. Histological preparations and immunohistochemical staining with insulin-like growth factor-1 were also done in the articular cartilages. All of these parameters were compared with those of osteoarthritic control group (n=7). The ethological inspection of foot print analysis revealed that changes of walking track (paw width) and stride length was significantly increased in both experimental groups. The better results were observed in experimental group treated with 25 intensity without significance than group treated with 500 . Histological preparations disclosed that routine hyaline cartilage of articular surface were altered to fibrous cartilage in untreated group and experimental group treated with 500 intensity. But a little changes were seen in experimental group treated with 25 intensity. Immunolocalization of insulin-like growth factor-1 was simultaneously decreased according to the duration of osteoarthritis, and did not show significant difference among the groups. In this study discovered that the microcurrent stimulation, especially 25 intensity, had a positive effect by the ethological inspection, histological and immunohistochemical stainings. These results suggest that microcurrent stimulation with low-intensity might be effective in the promotion of healing process for the osteoarthritis.

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 determine the effects of both transcutaneous electrical nerve stimulation (TENS) and microcurrent electrical neuromuscular stimulation (MENS) on DOMS, Twenty-seven untrained and male volunteer subjects were randomly assigned to one of three treatment groups: 1) a group that received TENS (7 Hz), 2) MENS (60 , .3 pps) or 3) a control group that received no 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 24 hours and 48 hours. Subjects attended on two consecutive days for treatment and measurement of elbow flexion, extension, resting angle (universal goniometer), and pain (visual analogue scale: VAS) on a daily basis. Measurements were taken after treatment. Analysis of results were as follows; 1) There were no significant differences between TENS and MENS by one-way repeated ANOVA, 2) The t-test for pain, resting, flexion and extension angle revealed significant differences within TENS group, 3) The t-test for resting angle revealed significant differences within MENS group.

The purpose of this study was to compare the effects of high intensity, high frequency microcurrent electrical neuromuscular stimulation(MENS) of auricular and somatic acupuncture points and low intensity, low frequency microcurrent electrical neuromuscular stimulation(MENS) of auricular and somatic acupuncture points on experimental pressure threshold at the elbow according to the time. Fifty healthy adults, aged 19 to 26 years, were assigned randomly to one of five groups: 1) the high intensity, high frequency somatic group(n=10) received MENS to somatic acupuncture points, 2) the high intensity, high frequency auricular group(n=10) received MENS to auricular acupuncture points, 3) the low intensity, low frequency somatic group(n=10) received MENS to somatic acupuncture points, 4) the low intensity, low frequency somatic group(n=10) receive MENS to somatic acupuncture points, and 5) the placebo group(n=10) received placebo treatment and served as controls. Pressure threshold was measured before, after, 5 minutes, 10 minutes and 15 minutes. Pressure threshold has increased significantly(p<.05) in the high intensity, high frequency auricular group following treatment after 5 minutes, with no statistically significant differences in pressure threshold change scores among five groups, Only the high intensity, high frequency auricular group demonstrated statistically significant change score in pressure threshold following treatment after, 5 minutes, 10 minutes and 15 minutes after compared to the placebo group. The results indicated that MENS applied to the high intensity, high frequency auricular group increases pressure threshold.

High Voltage Pulsed Current Stimulation(HVPCS) and Microcurrent Electrical Neuromuscular Stimulation(MENS) have been used to promote the healing of decubitus ulcer and surgical wounds. The benefits of HVPCS and MENS are thought to include an inhibitive effect on bacterial growth. The purpose of this study was to compare the inhibitive effect of two different electrical stimulation techniques growth in vitro. Using agarose-based media, the two bacterial species Staphylococcus aureus, Esherichia coli - which are commonly isolated from open wounds were incubated in an incubator for 24 hours following exposure to HVPCS(400 V, 120 pps, ) and MENS(, 0.3 Hz). We then measured the zone of inhibition around each electrode. Both HVPCS and MENS produced an inhibitive effect on bacterial growth in this vitro study. However MENS was more effective than HVPCS.
