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.

This study was conducted to assess the effect of transcutaneous electrical nerve stimulation(TENS) and interferential current(IFC) in the patients with myofascial pain syndrome(MPS) on upper trapezius. Twenty patients with MPS on upper trapezius was assigned randomly to TENS group(n=10), IFC group(n=10). In TENS group, TENS was applied to the trigger point. In IFC group, IFC was applied to the trigger point. Duration of treatment was 2 weeks. Effects were assessed before treatment, post treatment by visual analogue scale(VAS), and pain rating score(PRS). Significant change of VAS was noticed in TENS group and IFC group. Significant change of PRS was noticed in TENS group and IFC group. IFC groups were significantly higher than TENS group that of the VAS and PRS. These result showed that IFC is effective treatment method for pain control in patients with MPS.

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.

당뇨병성 신경병증은 환자의 자각증상이 없다하더라도 검사를 시행했을 시 신경전달속도가 떨어진다. 특히 감각신경과 자율신경의 손상이 지배적이다. 환자는 외부적인 압박에 대하여 감각이 둔하게 된다. 그로 인해 궤양이 생기고 보행과 자세조절에 문제가 생기게된다. 당뇨가 심하게 되면 환자는 가벼운 건드림조차도 통증으로 인지한다. 때로는 통증 때문에 잠을 잘 수 없기도 없다. 당뇨 치료법에는 인슐린요법, 식이요법 외에 운동치료가 당을 조절하는데 매우 효과적이다. 부가적으로 생기는 통증조절에는 경피전기신경자극이 적절하다. 앞으로의 당뇨환자들의 치료접근 중 물리치료 방법에 있어서, 궤양치료, 통증치료, 신경손상의 회복, 보행조절과 자세안정, 그리고 운동치료에 관한 더 많은 연구가 필요하다.

PURPOSE: This study aimed to compare the impact of exercise with that of functional electrical stimulation (FES) and transcutaneous electrical nerve stimulation (TENS) on muscle tone, calf muscle stiffness, and balance ability in patients with stroke. METHODS: Thirty patients with stroke were randomly divided into an FES group (n=15) and a TENS group (n=15), and a progressive task-oriented exercise was assigned to them. These exercises were performed non-synchronously from December 5, 2016 to January 31, 2017. Patients underwent TENS and simultaneously exercised for 30 minutes daily, 5 times a week for 4 weeks. To determine the effect of the interventions, muscle tone and stiffness of the medial and lateral region of gastrocnemius muscle were measured using the MyotonPRO instrument and balance was assessed using the Berg Balance Scale. RESULTS: Both groups revealed a significant decrease in muscle tone and stiffness of the medial part of gastrocnemius muscle before and after the interventions (p<.05). Berg Balance Scale scores increased significantly (p<.05). However, none of the other parameters were significantly different (p>.05). CONCLUSION: Our results prove that progressive task-oriented exercise along with FES and TENS decreases muscle tone and stiffness of the gastrocnemius muscle in patients with stroke and improves balance. TENS could serve as a complementary replacement for functional electrical stimulation for in-house training, as TENS poses less risk of muscle fatigue and has lesser contraindications than does functional electrical stimulation.

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.

Purpose: The purpose of this study was to compare the effects of scrambler and transcutaneous electrical nerve stimulation therapy on pain, functional disability, and depression in patients with chronic low back pain. Methods: Twenty patients with chronic stroke were assigned randomly to an experimental (n=10) or control (n=10) group. The experimental group performed scrambler therapy. The control group performed electrical nerve stimulation therapy. Training was conducted once a day for 30 minutes, five days per week, for three weeks. The pain was measured using the numeric rating scale. Functional disability was measured using the Roland-Morris disability questionnaire. Depression was measured using the Beck depression inventory. Results: As a result of comparison between the groups, the experimental and control groups showed significant difference for pain, functional disability and depression after the experiment (p<0.05). In a comparison between the two groups, the experimental group, in which scrambler therapy was applied, showed a more significant reduction in pain, functional disability and depression than the control group (p<0.05). Conclusion: Based on these results, scrambler therapy shows positive effects on pain, functional disability, and depression in patients with chronic low back pain.
