PURPOSE: This study examined the influence of treadmill exercise with initial pain control using transcutaneous electrical nerve stimulation (TENS) on induced pain of knee osteoarthritis in rats. METHODS: Thirty adult male Sprague - Dawley rats were divided randomly into the TENS Group (TG, n = 10), Treadmill Exercise Group (TEG, n = 10), and Treadmill with TENS Group (TTG, n = 10). In the TG, TENS was performed for 20 min per day for two weeks with a TENS program at the knee joint. The TEG performed treadmill exercise 15 m/min for 20 min per day for two weeks. The TTG performed initial pain control by TENS program during the 1st ~ 3rd days, and treadmill exercise was performed using the TEG methods from the 4th day. The lumbar spine was extracted and processed using western blot analysis to evaluate pain (c-fos expression). RESULTS: The results showed that c-fos expression was decreased significantly in all groups after each intervention (p < .05). In particular, TTG produced the most significant decrease compared to the other groups. CONCLUSION: These results suggest that treadmill exercise with initial pain control using TENS is a suitable method for relieving pain in knee osteoarthritis.

Background: This study investigates the effects of neuromuscular electrical stimulation (NMES) in preventing deltoid atrophy during the first 12 weeks after arthroscopic rotator cuff repair. Methods: Eighteen patients undergoing arthroscopic repair of a medium-sized rotator cuff tear by a single surgeon, were randomized into two groups: NMES and transcutaneous electrical nerve stimulation (TENS). Each group used the respective device for 6 weeks after surgery. Pain was measured at baseline, 6, and 12 weeks postoperatively, using the visual analogue scale (VAS); range of motion (ROM), abduction strength and functional scores were measured at baseline and 12 weeks postoperatively. Deltoid thickness and cross-sectional areas were measured using magnetic resonance imaging at 12 weeks postoperatively. Results: At 12 weeks post-surgery, no statistically significant difference was observed between the NMES and TENS groups in the pain VAS, the Disabilities of the Arm, Shoulder and Hand score, ROM, and abduction strength. Postoperative decrease in the thickness of the anterior, middle, and posterior deltoid, at the level just below the coracoid, was -2.5%, -0.7%, and -6.8%, respectively, in the NMES group, and -14.0%, -2.6%, and -8.2%, respectively, in the TENS group (p=0.016, p=0.677, and p=0.791, respectively). At the level of the inferior glenoid tubercle, postoperative decrease in area of the deltoid was -5.4% in the NMES group and -14.0% in the TENS group, which was significantly different (p=0.045). Conclusions: NMES has the potential for reducing deltoid atrophy after arthroscopic rotator cuff repair, suggesting that NMES might help minimize postoperative atrophy after various shoulder surgeries.

통증 관리를 위해 전기자극 중 경피신경전기자극과 간섭파전류가 사용되고 있다. 본 연구는 대상자에게 수정된 최대하 압박대 방법을 이용하는 실험적 허혈 통증모델에서 경피신경전기자극과 간섭파전류간의 통증 완화 효과를 비교하기 위해 실시되었다. 병리학적 문제로 인한 통증을 갖고 있지 않는 14명(남 7명, 여 7명)을 대상으로 실시하였고 대상자의 평균 나이는 $26.7{\pm}2.0$세 이었다. 본 연구는 단일맹검법, 위약군 방법을 이용하여 경피신경전기자극, 간섭파전류, 위약 전기자극 3가지 중재를 적용하는 동안 주기에 따른 통증 강도를 자가 설문을 이용해 측정하였다. 경피신경전기자극과 간섭파전류는 상지의 전완에 실시하였고 위약군은 가짜 자극기를 이용해 전류가 출력되지 않는 자극을 적용하였다. 연구 결과를 보면 이원-반복 분산분석에서 3가지 전기자극 동안 통증 강도 변화의 차이가 없었고 간섭파전류와 경피신경전기자극간에는 통증 강도의 변화가 다르지 않았다. 따라서, 통계적으로 간섭파전류와 경피신경전기자극 모두 통증 강도가 감소하였지만 두 전기자극간에 유의한 차이를 보이지 않으면 동등한 효과를 나타내었다. 대상자에게 인식되는 전기자극의 편안함과 통증 완화 효과면에서 간섭파전류가 경피신경전기자극 보다 더 선호되었다.

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.

본 연구의 목적은 Needle TENS를 이용하여 웅성 흰쥐를 대조군과 실험군으로 나누어 말초신경손상의 좌골신경을 30초 압좌하여 1일, 3일, 5일, 7일 치료 후 NGF의 변화를 본 결과 다음과 같은 결론을 얻었다. 대조군에서는 1일째 면역반응 신경세포의 수가 많이 증가된 것으로 관찰되었으며, 3일, 5일, 및 7일로 시간이 경과할수록 반응하는 신경세포수는 점점 감소하는 경향을 나타냈으나, 신경손상을 받지 않은 정상부분의 반응양성과 유사한 결과를 나타내었다. 그러나 실험군에서는 1일째는 대조군과 실험군간의 별다른 차이를 보이지 않았으나 3일, 5일, 7일 단위로 치료기간이 길어짐에 따라 면역반응 신경세포의 변화는 뚜렷하게 관찰할 수 있었는데, 대조군과 실험군간의 NGF 변화에서 시간이 경과함에 따라 감소되는 결과를 보였고, 대조군보다는 실험군에서 현저하게 감소하는 것으로 나타났으며, 통계적으로도 유의한 결과를 보였다. 이러한 결과로 볼때 Needle TENS를 적용하니 NGF의 감소를 보여 치료를 촉진시켜 치유과정에 영향을 미친다고 할 수 있다.

경희대학교 치의학전문대학원 학생 16명을 대상으로 경피신경자극치료기(TENS)의 기능별 주파수에 따른 교근과 피개상 피의 혈류변화에 관하여 관찰한 결과 다음과 같은 결과를 얻었다. 1. TENS를 적용한 실험에서 근육에서의 혈류가 증가된 것은 1.5, 3.0 Hz에서 관찰되었다. 2. TENS를 적용한 실험에서 근육에서의 이동혈류의 농도가 증가된 것은 1.5, 3.0, 6.0 Hz에서 관찰되었다. 3. TENS를 적용한 실험에서 근육에서의 혈류 속도가 증가된 것은 1.5 Hz에서만 관찰되었다. 4. 6.0Hz와 10.0Hz의 TENS를 적용한 실험에서 혈류, 이동혈류의 농도, 혈구 속도의 증가율이 모두 상피에 비하여 근육에서 낮게 나타났으며, 특히 6.0Hz의 혈류와 혈구 속도, 10.0 Hz의 혈류에서 가장 빈번하였다. 이상의 실험결과로 TENS를 적용한 물리치료를 시행할 경우에는 1.5, 3.0 Hz의 주파수가 효율적이며, 주파수의 강도가 높아질수록 근육에 미치는 영향은 바람직하지 않을 것으로 생각된다.

Objective: Transcutaneous electrical nerve stimulation (TENS) is a treatment method for pain, and it can be divided into conventional TENS (C-TENS) and acupuncture-like TENS (A-TENS). More recently, high power lasers have increasingly been used to reduce pain caused by arthritis, residual neuralgia, and musculoskeletal disorders. The aim of this study was to compare the laser needle with C-TENS and A-TENS in terms of pain and blood flow in healthy people, as well as to confirm that the laser needle can replace TENS to treat pain. Design: A randomized controlled trial. Methods: The selected participants were divided using Minimize computer software into a laser group (n=13), a C-TENS group (n=13), and an A-TENS group (n=14); they underwent a pre-test for blood flow and pain in their forearm. The three groups received their respective interventions; they then underwent a second pain and blood flow test on the same spot. Results: No significant differences were observed in the A-TENS group between the pre- and post-tests, and a comparison among the three groups revealed no significant differences between the laser needle group and the C-TENS group in terms of pain. Regarding blood flow, no significant differences were found between the pre- and post-tests in the laser needle group; a comparison among the three groups only revealed a significant between the laser needle and A-TENS groups. Conclusions: This study confirmed that the laser needle can be used to treat pain when it is necessary to control blood flow.

Purpose : This study observed the recovery of function and pain on the eletrostimulation therapy(transcutaneous electrical nerve stimulation(TENS) and micro current therapy(MT)). Methods : Subjects were assigned randomly either experimental group(n=17) who were taken TENS or the control group(n=20) who were taken MT. Also subjects were assessed for pain(Visual Analog Scale; VAS) and function(Oswestry LBP disability index). Results : The VAS has a statistically significant difference with each groups(p<.05), but there was no statistically significant difference with intergroup during treatment period(p>.05). The Oswestry LBP disability index has a statistically significant difference with each groups(p<.05), also there was a statistically significant difference with intergroup during treatment period(p<.05). Conclusion : The efficancy of microcurrent therapy used in this study should be futher investigated in a long period study and objective study outcomes.

Background: The purpose of this research is to investigate the effects of joint mobilization and transcutaneous electrical nerve stimulation (TENS) on pain threshold and hormonal changes in patients with chronic LBP. Methods: 14 patients with chronic LBP were divided into the experimental group and the control group with 7 patients each, and both groups of patients were evaluated on pain duration, blood tests, and pressure pain threshold (PPT) on their first visit. On their second visit, joint mobilization was applied to the experimental group for 10 min and TENS to the control group for 20 min. Results: Pain threshold and duration of analgesia increased from after treatment in the experimental group. Serotonin and Cortisol decreased after treatment in the experimental group. Conclusion: Joint mobilization in patients with chronic LBP caused an increase in pain duration and pain thresholds and a decrease in serotonin, whereas there was little difference in cortisol.
