The purpose of this study was to compare the application method of ultrasound on the alteration of pressure pain threshold of myofascial trigger points. We used thirty patients with mayofascial pain syndrome in upper trapezius. Participants classified according to each group in non noxious dose, noxious dose by the ultrasound. The test was measured continuously pre test, post-test by algometer. The following results were obtained; 1. Pressure pain threshold were significantly increased in non-noxious dose and noxious dose group(p<.001). 2. In noxious dose group, pressure pain threshold were more significantly increased than non-noxious dose group(p<.001). These results lead us to the conclusion that non-noxious dose and noxious dose were significantly increased pressure pain threshold of upper trapezius trigger points. Therefore, a further direction of this study will be to provide more evidence that noxious dose have more effect on pressure pain threshold of myofascial trigger points.

We have observed retroperitoneal hematoma after trigger point injections of quadratus lumborum in a patient with chronic low back pain. Severe flank pain and dyspnea was observed three hours after injection of local anesthetic and steroid to the trigger point of quadratus lumborum muscle. There was fuge hematoma in abdominal CT image around the right kidney, which displaced and compressed the kidney anteriorly. Following infusion of contrast media, extravasation through renal vein and IVC was notified. Patient had a past history of having been treated with platelet aggregation inhibitor and lower dose aspirin treatment after cerebral ischemia for a year, but coagulative function was within normal range. Patient was admitted 12 days for bed rest, pain control and transfusion. We need to take greater care with a frequent aspiration and exact direction of needle, during trigger point injection of quadratus lumborum, particu right side, to avoid vascular injury.

The fault current of the power transmission system is greater than that of the power distribution system. Therefore, the introduction of superconducting fault current limiter (SFCL) is more needed to reduce the increased fault current. The trigger-type SFCL consists of the high-temperature superconducting element (HTSC), the current limiting reactor (CLR) and the circuit breaker (CB). The trigger-type SFCL can be used to supplement the disadvantages of the resistive-type SFCL. The operation characteristics of the current ratio differential relay which is usually applied to the protection device of the power transmission system are expected to be affected under fault conditions and the applicability of the trigger-type SFCL. In this paper, we analyzed the operating characteristics, by the fault conditions, between the current ratio differential relay for line protection and the trigger-type SFCL in the power transmission system through the PSCAD/EMTDC simulation.

We investigated the quench characteristics in accordance with increase of turns number of trigger coil and shunt resistance of matrix-type superconducting fault current limiter (SFCL) with $2{\times}3$ array. The matrix-type SFCL consists of the trigger part to apply magnetic field and the current-limiting part to limit fault current. The fault current limiting characteristics according to the increase of magnetic field and applied voltage were nearly same. This is because the application of magnetic field hasn't an affect on total impedance of the SFCL. When turns number of a reactor increased, the voltage difference between two superconducting units in the current-limiting part according was decreased. The resistance difference generated in two superconducting units was also decreased. Therefore, we confirmed that the differences of the critical behaviors between superconducting units were reduced by application of magnetic field. By this results, we could decide the optimum turns number of reactor to apply magnetic field.

The purpose of this study is the evaluation of the degree of post injection soreness, symptom duration, factor and autonomic symptoms after trigger point injection in patients with trigger points. We devided the subjects of the study into four groups Such as, only dry needling, needle-TENS, with massage-stretch, massage-stretch only, including 100 patients, and measured the visual analog scale before treatment and after treatment. Before treatment, The VAS mean scores were $6.2{\pm}1.03$ in needle-TENS with massage-stretch group ; $6.2{\pm}1.75$ in needdle-TENS group, and $6.3{\pm}1.85$ in dry needling group, and $6.8{\pm}1.03$ in massage-stretch group. In post injection 3rd day, The VAS mean score were $0.9{\pm}1.78$ in needling-TENS with massage-stretch group, $1.1{\pm}1.52$ in needling-TENS group, $1.7{\pm}1.10$ in dry needling group, and $3.9{\pm}3.01$ in massage-stretch group. As for a causative factor of activities for trigger were overload with 37.0%, overwork with 35.0% and fatigue with 13.0%. Symptoms for trigger were tenderness with 28.0%, numbness and tingling with 24.0%. ROM limit with 17.0% and tightness with 17.0%. As a result, needling-TENS with massage-stretch group showed less soreness and effect than other group.

This paper is introducing a newly developed spark-gap switch with dual trigger system, into which the current from the voltage source is injected along with the test sequence during the synthetic testing of high voltage circuit-breaker. The currently-used spark gap switch is narrow in operating range due to the use of the method of triggering energy being injected by single way. As a result, the frequent happening of misoperation has greatly reduced the test quality and test efficiency and has required the cost of maintenance excessively. In this study, accordingly, in order to basically remove these problems, another triggering system is installed to the opposite direction on the existing triggering system; attaching the same time and the same rising time of pulse wave as on the existing system, so that at a comparatively trigger gap distance from the main electrode(the gap can be operated at 60% of self-break voltage, while at 80% in the current system), the main electrode has been enabled to be closed by the development of spark gap switch with dual trigger system.

Headache is a common disease of the general population. But the main problem in any study of headache has been that of defining the disease entities. In 1988, the Headache Classification committee of the International Headache Society introduced operational diagnostic criteria for all headache disorders into 13 major group; migraine, tension-type headache, cluster headache and chronic paroxysmal hemicrania etc. Sjaastad was the first to describe "cervicogenic headache", one of various head pain syndromes that probably originate in the cervical spine. Between March 1995 and June 1995, we studied 78 out-patients of the Department of Neuro pain clinic, Sanggye Paik Hospital, Inje university. We divided the patients into three study group: Fifty-three patients with tension-type headache, 13 with cervicogenic headache, and 12 with migraine headache. The reponse of trigger point injection and $C_2$-ganglion block in patients was investigated. We paid particular attention to the response of trigger point injection in patients of the three group. The effect of trigger point injection was more marked in tension-type headache group than in the other categories. The pain reduction after $C_2$-ganglion block was more marked in cervicogenic headache group than in the others.
