Among the methods of treating tinnitus, the transcutaneous clectrical nerve stimulation (TENS) method of treating by electrical stimulation is common. However, there is a problem that surgical operation is required to stimulate the vagus nerve (VN) main trunk near most of the bronchus. Alternatively, we found that the same effect could be achieved by electrically stimulating the vagus nerve VN branch (Arnold's nerve) distributed in the outer ear. The TENS system for stimulation of vagus nerve has been developed, but it has not been able to implement to stimulate as a parameter optimized for the patient by simultaneously playing the sound of eliminating the tinnitus frequency. Therefore, in this paper, it is important to develop a safe and practical TENS device for tinnitus treatment based on a 32-bit microprocessor that simultaneously applies non-invasive and notched sounds and to develop optimal treatment methods for treating tinnitus.

Temporalis tendon transfer is a technique for dynamic facial reanimation. Since its inception, nearly 80 years ago, it has undergone a wealth of innovation to produce the modern operation. Temporalis tendon transfer is a relatively minimally invasive technique for the dynamic reanimation of the paralyzed face. This technique can produce significant and appropriate movement of the lateral oral commissure, more closely mimicking the normal side. The aim of this article is to review the technique of temporalis tendon transfer involving transferring of the coronoid process of the mandible with the insertion of the temporalis tendon via intra-oral and transcutaneous approach.

Purpose：The purpose of this study is to investigate the effect of transcutaneous electrical stimulation on autonomic nervous system using heart rate variability analysis. Methods：31 subjects were evaluated with HRV before and after a single high-frequency TENS for 15minutes treatment. The standard deviation of all the normal RR-interval(SDNN) and lower frequency/high frequency ratio(LF/HF ratio) were recorded with TAS-9. Results：After single TENS treatment, autonomic adaptation as analyzed by SDNN was increased from $42.47\pm12.96$ to $4.43\pm16.76$(p>0.05) and autonomic balance as analyzed by LF/HF ratio was increased from $1.4\pm0.45$ to $1.45\pm0.41$(p>0.05). Conclusion：In this study, SDNN and LF/HF ratio changed in health young students as a result of single TENS treatment. But there is no significant difference between pre-treatment and post-treatment of SDNN and LF/HF ratio.

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.

Purpose: The purpose of this study was to examine the effect on plasma beta endorphin concentration level and the influences on pain score of transcutaneous electrical nerve stimulation (TENS) mediation to patients During a prostate needle biopsy. Methods: TENS was administered to only the experimental group. The electric current was given in high frequency (40-100 pps) and low intensity ($2-50{\mu}s$) from the waiting room stage until the end of the procedure. The average time spent was 35 minutes. Following 10 minutes of retention in the rectum, there was a biopsy. In two groups, the pain score was assessed twice when vas pain penetrated into the rectum, during the needle biopsy. The Beta endorphin concentration level was assessed through blood gathering 2 times in the Nuclear Medicine Labs before and after the test. Results: There was not much difference in pain levels from both groups when a microscope probe penetrated into the rectum and in the time when tissues were collected. However, the average overall pain level was reduced during those two procedures. The plasma beta endorphin level was increased in the TENS medicated group compared with the unmedicated group after the procedures were completed. Conclusion: The research indicates that TENS was desirable to be considered as a non-invasive method for controlling pain.

Objectives To evaluate the clinical usefulness between muscle energy techniques (MET) and transcutaneous electrical nerve stimulator (TENS), we performed both on elector spinae muscle of acute low back pain patients. Methods After performing MET and TENS, we compared both in terms of electrical activity. We performed MET or TENS on elector spinae muscle of acute low back pain patients in each group (n=15,15). After performing MET or TENS, we analyzed root mean square (RMS), median edge frequency (MEF) and asymmetry index (AI). Results 1. After performing MET on elector spinae muscle of acute low back pain patients, RMS was significantly decreased compared with before (p<0.005). 2. After performing TENS on elector spinae muscle of acute low back pain patients, RMS was significantly decreased compared with before (p<0.005). 3. After performing MET on elector spinae muscle of acute low back pain patients, asymmetric index was significantly decreased compared with before (p<0.05). Conclusions According to above results, performing MET on elector spinae muscle of acute low back pain patients has effect in terms of RMS and asymmetric index. And performing TENS on elector spinae muscle of acute low back pain patients also has similar effect in terms of RMS but has not in terms of asymmetric index.

Background: Transcutaneous electrical nerve stimulation (TENS), manual acupuncture (MA), and spinal cord stimulation (SCS) are used to treat a variety of pain conditions. These non-pharmacological treatments are often thought to work through similar mechanisms, and thus should have similar effects for different types of pain. However, it is unclear if each of these treatments work equally well on each type of pain condition. The purpose of this study was to compared the effects of TENS, MA, and SCS on neuropathic, inflammatory, and non-inflammatory pain models. Methods: TENS 60 Hz, 200 ㎲, 90% motor threshold (MT), SCS was applied at 60 Hz, an intensity of 90% MT, and a 0.25 ms pulse width. MA was performed by inserting a stainless-steel needle to a depth of about 4-5 mm at the Sanyinjiao (SP6) and Zusanli (ST36) acupoints on a spared nerve injury (SNI), knee joint inflammation (3% carrageenan), and non-inflammatory muscle pain (intramuscular pH 4.0 injections) in rats. Mechanical withdrawal thresholds of the paw, muscle, and/or joint were assessed before and after induction of the pain model, and daily before and after treatment. Results: The reduced withdrawal thresholds were significantly reversed by application of either TENS or SCS (P < 0.05). MA, on the other hand, increased the withdrawal threshold in animals with SNI and joint inflammation, but not chronic muscle pain. Conclusions: TENS and SCS produce similar effects in neuropathic, inflammatory and non-inflammatory muscle pain models while MA is only effective in inflammatory and neuropathic pain models.

In this study, we carried out a basic study for the development of optical transcutaneous $pCO_{2}$ gas sensor and analyzer using non-invasive method. The basic principle of $pCO_{2}$ measurement is adapted Beer lambert's law and embodied the system using NDIR method. This measuring system was composed of a IR lamp, a optical filter, a optical reaction chamber, pyroelectric sensor and a signal process. We measured $EtCO_{2}'s$ concentration in basis step instead of $pCO_{2}$ gas that can collect by inflicting heat in outer skin. We minimize the size of optical reaction chamber which takes up the largest volume, to make the portable sensor. We made optical reaction chamber in Si wafer using MEMS technology and the optical reaction chamber was shortened to 2 mm and we carried out an experiment. When we injected the $EtCO_{2}$ to the inside of the optical reaction chamber, we could confirm change of 4.6 mV. The system response time was within 2 second that is fairly fast.
