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 ${\mu}A$, .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.

본 연구는 8방향 경사와 회전운동이 만성요통환자의 통증과 동적균형에 미치는 영향을 알아보고자 시행되었다. 20명의 만성요통환자가 실험에 참여하였다. 10명(실험군)은 물리치료기구[온열팩{Hot Pack(H/P), 경피신경자극{Transcutaneous Electric Nerve Stimulation(TENS)}, 초음파{Ultra Sound(U/S)}]를 이용한 치료를 받은 후에 8방향 경사와 회전운동을 실시하였고 나머지 10명(대조군)은 물리치료기구를 이용한 치료만 실시되었다. 치료 중재는 주 3회, 6주 동안 적용되었다. 동적균형과 통증은 Star Excursion Balance Test(SEBT)과 Visual Analog Scale(VAS)를 이용하여 측정하였다. VAS 점수는 두 그룹 모두 감소하였으나 실험군에서 보다 유의하게 감소하였다. 동적균형 능력 또한 실험군에서 보다 유의한 증가를 나타내었다. 따라서 8방향 경사와 회전운동은 만성요통환자의 통증과 동적균형에 효과가 있었다고 사료된다.

Background: Transcutaneous electrical nerve stimulation (TENS) has been used widely, but its effects are controversial. This is probably due to the varying intensity and type of pain. We designed a study to assess the effects of the TENS on the RIII nociceptive flexion reflex as the resting pain level and the temporal summation as a repeated, movement related pain in 7 normal volunteer subjects. Methods: High frequency (80 Hz), non-noxious TENS was applied over the left popliteal fossa for 20 minutes. Ipsilateral RIII reflexes induced by single electrical stimulus and temporal summation of pain responses to repeated stimuli (five stimuli at 2 Hz) were recorded before, during (just before stopping), and subsequently at 20 minutes after TENS. Results: R (III) nociceptive flexion reflex activity during and after TENS was more significantly decreased than before treatment. However, the temporal summation threshold was not changed. Conclusions: We conclude that high frequency, non-noxious TENS could be effective on resting pain relief in the same segment but not on the movement related pain.

The purpose of this study was to investigate the changes of muscle power by transcutaneous electrical nerve stimulation(TBNS), low frequency-low intensity(20pps, invisible muscle contraction intensity), low frequency-high intensity(20pps, visible muscle contraction), high frequency-low intensity(100pps, invisible muscle contraction intensity) and high frequency-high intensity(100pps, visible muscle contraction). The results were as follows. 1. Increased muscle power after 30 minutes of treatment by low frequency-low intensity TENS, and post-treatment 30 minutes muscle power were increased more than pre-treatment power(p<0.05). 2. Decreased muscle power after a 30 minute treatment by low frequency-high intensity TENS, and after the 30 minute treatment was terminated muscle power didn't recover to pre-treatment levels. 3. Decreased muscle power after 30 minute treatment by high frequency-low intensity TENS, but post-treatment 30 minute, muscle power didn't recover to pre-treatment levels. 4. The muscle power was remarkably decreased by high frequency-high intensity TENS after 30 minute treatment, in addition treatment terminated after 30minutes didn,t recover to pre-treatment power(p<0.05). 5. Lower frequency-low intensity TENS are good methods for preventing muscle fatigue, buty high intensity (TENS) are increased muscle fatigue. 6. Traditional TENS by high frequency-low intensity is a good method for preventing muscle fatigue.

The purpose of this study was to examine the effect and $\beta-endorphin$ level as conventional transcutaneous electrical nerve stimulation (TENS) application on acupuncture paints. Twelve healthy adult male volunteers were participated in this study. The subjects were assigned to TENS group (n=6) and naloxone group (n=6). The LI 3 and M 10 meridian points of dominant arm were stimulated comfortably with 100 pps, $75{\mu}s$ conventional TENS for 30 minutes. Experimental pain threshold measurement and plasma $\beta-endorphin$ level were detected before and after conventional TENS application. Experimental pain threshold increased significantly (p<.01) but plasma $\beta-endorphin$ level was not change in TENS group. Experimental pain threshold increased significantly (p<.01) but plasma $\beta-endorphin$ level was not change in naloxone group. In this study, the conventional TENS induced analgesic effect, and plama $\beta-endorphin$ level was not increase concomitantly with analgesia. These results suggest that the $\beta-endorphin$ did not involved in conventional TENS analgesia.

The purpose of this study was to examine the effect of transcutaneous electrical nerve stimulation(TENS) in the patients of dysmenorrhea. A total of thirty subjects were assigned randomly to one of the two experimental groups or to a control group : 1) an Experimental group I received high-frequency TENS(100pps with a 100-microsecond pluse width), 2) an Experimental group II received low-frequency TENS(2pps with a 100-microsecond pulse width), 3) a Control group received medication(Acetaminophen 600mg). All subjects completed visual analogue scale(VAS) pre-treatment; after post-treatment; 1, 2, 3, 4, and 6 hours post-treatment; and the next morning. The results of study were as follows; 1. The mean pain scores decreased in thru groups. 2. The experimental group II and the control group exhibited a significant decrease in pain post - treatment. 3. The experimental group I had the pain relief obtained after three hours post - treatment. The experimental group II had the pain relief obtained immediately after the post - treatment Control group had the pain relief obtained immediately after the post - treatment, but increased pain after four hours of post-treatment. Finally. this result suggests that TENS can reduce significantly the pain of dysmenorrhea. Besides. low-frequency TENS provided a good result to the excellent subjective pain relief in the subject, compared with high-frequency TENS and medication.

The purpose of this study was to investigate the influnce of afferent stimuli, transcutaneous electrical nerve stimulation and ultra sound, on the electrdiagnostic study of normal subjects. Electrodiagnostic study was performed before and after the application of afferent stimulation of the right popliteal fossa on 18 healthy female volunteers. After the transcutaneous electrical nerve stimulation, there is no significantly change of latencies and amplitudes of SEP, H-reflex, peroneal nerve F-wave, and sensory nerve conduction. After the ultra sound, there is no significantly change of latencies and amplitudes of SEP, H-reflex, peroneal nerve F-wave, and sensory nerve conduction. Tibial nope F-wave and motor nerve shows prolonged latency after TENS and US (p<0.01). Ultrasound may have a similar mechanism of action compared to transcutaneous electrical nerve stimulation by having localized inhibitory effects of the peripheral nerve. However, further investigation is needed to assess their mechanism of action and the precise relevance of stimulation modality.

The purpose of this study were to determine the changes between pre, during, intermed, post of each two groups of 16 persons and to compare the effect of transcutaneous electrical nerve stimulation(TENS) at shenmen of auricular point on experimental pressure pain and tactile threshold measured at both ulnar styloid process and medial malleoli. Sixteen healthy adult men and women, aged 20 to 28 years, were assigned randomly to eight of one groups. Control group received TENS to exception of auricular point. Experimental group received TENS to shenmen of auricular point. Experimental pressure pain and tactile pain threshold at the both ulnar styloid process and medial malleoli was determined with algometer and von frey filament before 10 minute, during 10 minute, intermediate and post 30 min of treatment. In pressure pain and tactile threshold showed a statistically significant increase(p<0.05) ipsilateral and contralateral of treatment group. These results suggest that TENS at shenmen of auricular point has the capability to higher pressure pain and tactile threshold in whole body.
