The purpose of this study were to examine the effect of high intensity, low frequency transcutaneous electrical nerve stimulation at auricular acupuncture points on experimental pain threshold measured at the wrist and to determine the changes in effect over time. Forty-two healthy adult men and women were assigned randomly to one of three treatment groups. Group 1(n=15) received TENS to appropriate auricular points for wrist, Group 2(n=12) received TENS to wrist, and Group 3(n=15) received no TENS. We measured experimental pain threshold at the wrist after an electrical stimulus during one pre-treatment and three post-treatment time periods. Group 1 and 2 showed stastically significant increase(p<0.05) in pain threshold after treatment whereas the Group 3 did not. Group 1 showed a significant increase in pain threshold than Group 2. These results suggest that high intensity, low frequency TENS applied to appropriate auricular acupuncture points can increase pain threshold.

Purpose : The purpose of this study was to compare Mulligan technique with Transcutaneous electrical nerve stimulation(TENS) in persons with neck pain. Methods : Twenty subjects with neck pain participated in the experiment. All subjects randomly assigned to the Mulligan technique group and TENS group. Both groups receive treatment(Mulligan technique: all areas 8 times once, TENS : 100Hz 15 minute once) 3 times during 2 weeks. And LEX was used to measure range of motion of neck. All measurement of each subject were measured at pre-treatment and post-treatment. Results : 1. All areas of range of motion of neck were significantly increased (p<0.05). 2. These data suggest that Mulligan technique and TENS are beneficial to increase all areas of range of motion of neck. 3. Comparing with two groups, Mulligan technique increases all areas of range of motion of neck more than TENS and appeared significant difference statistically. Conclusion : Mulligan technique is more effective than TENS to increse range of motion in persons with neck pain.

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.

Interferential currents (IFC) and transcutaneous electrical nerve stimulation (TENS) are used for pain management. This study compared the analgesic effects of IFC and TENS on experimentally induced ischemic pain in otherwise pain-free subjects using a modified version of the submaximal-effort tourniquet technique. The subjects were 14 volunteers (7 male, 7 female) without known pathology that could cause pain. Their mean age was $26.7{\pm}2.0$ years. A single-blind, sham controlled, parallel-group method was used. The primary outcome measure was the change in the self-report of pain intensity during 1 of 3 possible interventions: (1) IFC, (2) TENS, or (3) sham electrotherapy. The IFC and TENS were administered on the forearm, and the sham electrotherapy group received no current output via a dummy stimulator. The results show that a 2-way repeated-measures analysis of variance revealed that there was no change in pain intensity during treatment when all 3 groups were considered together. The mean to pain intensity with the IFC intervention was no different than with TENS. Thus, Statistical analysis showed that both interventions decreased the pain intensity ratings significantly and the difference between interventions was not simply insignificant. IFC has been shown to be more comfortable than TENS in present studies and is likely to be better accepted and tolerated by patients, clinical investigation is warranted.

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.

The following results were obtained, after experimenting on change of masseter muscle and bloodstream epithelium with Transcutaneous Electrical Nerve Stimulator(TENS), among 16 male adults. 1. According to applying TENS, it was observed that bloodstream in muscle increases at 1.5, 3.0 Hz. 2. According to applying TENS, it was observed that concentration of moving blood cells in muscle increase at 1.5, 3.0, 6.0 Hz. 3. According to applying TENS, it was observed that velocity of bloodstream in muscle increases only at 1.5 Hz 4. Through experiment, applying TENS at level of 6.0 and 10.0 Hz, all bloodstream, concentration of moving blood cells, and velocity of bloodstream increasing rates were lower in muscle compared to of them in overlying epithelium; and especially increasing bloodstream and its velocity were most frequent at 6.0 Hz, and bloodstream of 10.0 Hz. From the results above when a physical therapy of TENS is carried out the frequency of 1.5, 3.0 H is effective, and as the frequency increases it is disadvantageous to the muscle.

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.
