  • This paper describes the development of needle type probe that measures temperature and injects medicine for both diagnosis and treatment of musculoskeletal pain syndrome (MPS). The size of trigger points is from several micrometers to millimeter. Therefore, it is required to develop a medical device that is capable of not only finding the trigger points by temperature measurement, but also injecting medicine at the exact location for treatment. To challenge these difficulties, thermocouple was fabricated on the surface of a needle using metal deposition process. Special type of stainless-constantan thermocouple was achieved from the stainless body of a needle itself and deposited constantan metal film. In particular, parylene coating enables to limit the temperature sensitive area to the end of the needle tip. Fabricated needle type probe produces $3.25mV/^{\circ}C$ of thermoelectric sensitivity and compared its performance with commercial T-type thermocouple in animal muscle sample.

  • The purpose of this study is to compare Ultra Sound(U-S), Silver Spike Point(SSP) and Electro-Acupuncture(E-A) with each other and to objectively analyze their concrete validities and their effects on the deactivation of trigger points in patients with myofascial pain syndrome, and to provide basic necessary principles for clinical therapists. Sixty patients were randomly distributed into three groups of twenty persons each and the U-S, the SSP and the E-A were applied to each group respectively. Tree pain evaluation methods of VAS(Visual Analogue Scale), Electrical Stimulation Scale and Pressure Algometer were adopted to measure the effectiveness of each therapy. The results were as follows: The U-S and E-A groups demonstrated statistically significant decrease on the VAS. The pain thresholds by Electrical Stimulation Scale method was increased for all the groups of U-S, SSP and E-A with no statistical significance. however, Pressure Algometer method was found to increase the pain thresholds for both SSP and E-A groups with statistically significance. Statistically significant improvement was found for all the groups together after the administration of the U-S, the SSP and the E-A. From the above results, three methods of U-S, SSP and E-A are found to be effective tools for the deactivation of trigger points in patients with upper trapezius muscle of Myofascial Pain Syndrome. The E-A method was found to be the most effective among three methods.

  • Patients with a wide range of cerebrovascular disease may have difficulty in opening their mouths, resulting in failing to swallow foods and maintain their oral hygiene. K-point was introduced as an effective trigger point to stimulate the jaw opening reflex for those patients. K-point stimulation may be useful as one of methods of helping open the jaw for dental examinations, or for placing foods onto the dorsum of the tongue and swallowing them effectively. Although this method cannot always guarantee the success of the jaw opening for every patient, it may still be considered to be an effective one to apply to patients having difficulty in jaw opening and swallowing disorder.

  • In this paper, we propose a signal processing board suitable for a semi-active laser tracking to detect an optical signal generated from the laser target designator by applying an analog trigger signal, the quadrant photodetector and a high speed ADC(analog-digital converter) sampling technique. We improved the stability by applying the averaging method to minimize the measurement error of a gaussian pulse. To evaluate the performances of the proposed methods, we implemented a prototype board and performed experiments. As a result, we implemented a frequency counter with an error 14.9ns in 50ms. PRF error code has a stability of less than 1.5% compared to the NATO standard. Applying the three point averaging method to ADC sampling, the stability of 28% in X-axis and 22% in Y-axis than one point sampling was improved.

  • Objective: This study aims to investigate high energy and low energy extracorporeal shockwave therapy (ESWT) and which one is more effective for shoulder pain. Design: Single blind randomized controlled trial. Methods: Fifty two subjects with upper trapezius (UT) trigger point (TrP) participated in this study. They were allocated to high energy (n=26) and low energy group (n=26). This study applies ESWT and investigates the changes of pressure pain threshold (PPT) and visual analogue scale (VAS). The high and low energy groups received focused piezo electric type ESWT 4 Hz, 1,000 pulses and 0.351 and $0.092mJ/mm^2$ respectively. Outcome measures of PPT and pain was measured by algometer and pain VAS. These measurements were performed before and after treatment. Results: The PPT value was significantly increased in both groups after treatment (p<0.05) and VAS scores were significantly decreased after treatment in both groups (p<0.05). However, there were no significant differences between groups. Conclusions: ESWT is an effective treatment for the application of the UT TrP. Although there were significant effects of extracorporeal shock wave therapy on PPT and VAS scores, there were no signficant differences between high and low energy extracorporeal shock wave therapy.

  • Acupuncture is so effective and simple to use in the pain and dysfunction syndrome of TMD. Acupuncture treatment is a point-specific. So, the selection of acupuncture point is very important. According to the traditional meridian theory, we select the points; local points around TMJ and mastication muscles(ST6, ST7, GB20, GB21) and remote point(LI4). And if there is another pain, one or two other points are added. Both neural and humoral mechanism play an important role in acupuncture analgesia. The discovery of spinal gate mechanisms shows somatic stimulation can induce pain inhibition. Humoral mechanism has been established from the discovery of opioid receptors and endogenous opioids. Acupuncture induces a relaxation in the patient, which further decreases the muscle tension.

  • PURPOSE: The purpose of our study was to compare a 975-nm, 500-mW GaAlAs low-level laser therapy versus placebo low-level laser therapy with regard to the immediate changes on the myofascial trigger point of the dominant upper trapezius muscle in subjects with rounded shoulder posture. METHODS: Thirty-two male college students with rounded shoulder posture and shoulder pain consented to participate in the experiment. The subjects were randomly assigned to a 2-minute procedure with either an active GaAlAs low-level laser or a placebo GaAlAs low-level laser. The pressure-pain threshold and visual analog scale on tenderness at 3 kg were measured with an algometer before and after the laser treatments. RESULTS: The active GaAlAs low-level laser group showed significant changes in pressure-pain threshold and visual analog scale on tenderness at 3 kg (p<0.05). The placebo GaAlAs low-level laser group showed no significant changes in either pressure-pain threshold or visual analog scale on tenderness at 3 kg (p>0.05). CONCLUSION: An immediate effect was observed in pressure-pain threshold and visual analog scale on tenderness at 3 kg following a 2-minute application ($857.14J/cm^2$) of a 975-nm, 500-mW GaAlAs low-level laser to the myofascial trigger point of the dominant upper trapezius muscle in patients with rounded shoulder posture.
