Background: At present, there is no reliable objective test for the diagnosis of myofascial trigger points (MFTP). We evaluated the usefulness of skin resistance point finder for the diagnosis of MFTP. Methods: 40 subjects with clinical MFTPs at the upper trapezius muscle were included in this study. Using skin resistance point finder (UNIQUE S-2010$^{(R)}$, Seik medical, Korea), we tried to find out the point of low skin resistance. At three different current level, sensitivity and specificity of this method for the diagnosis of clinically identified MFTP was evaluated. Pressure threshold for pain of low skin resistance point was measured using Pressure Threshold Meter$^{(R)}$ (Pain Diagnostics and Thermography, U.S.A.). 3 groups of point detected at different current were compared in mean pressure threshold. Results: Fixed single current of skin resistance point finder showed variable sensitivity and specificity. But, by adjusting current level, skin resistance point finder detected all of 40 clinically identified MFTPs. Although it is partially statistically significant, the mean pressure threshold of points detected at high current was high. Conclusion: Skin resistance finder can be used as objective diagnostic tool of MFTPs. There is possibility that it can be useful in evaluating treatment effect. However, more investigation is necessary.

Purpose : This study is to offer clinical primary data that examines the change of imaging structure and the quantitative evaluation of muscle activity on myofascial trigger points. This study examines neuromuscular physiological characteristic by comparing the differences in physical findings, pressure pain threshold, imaging, and electrophysiological characteristics in latent and active myofascial trigger points muscle and normal muscle through the following experimental procedures. Methods : The participants for the study were thirty-three adults in their twenties. We divided three groups into normal, latent and active myofascial trigger points groups by physical findings. We analyzed the results of measured pressure pain, threshold for pain, ultrasound imaging perform for structure characteristic of muscle, surface EMG according to type of muscle contraction for function of muscle contraction. Results : Significant differences were indicated in pressure pain threshold (p<0.05). Significant differences were discovered in the ultrasound imaging analysis. There were increases in muscle Echogenicity white area index (p<0.001). There were significant differences that decrease in %MVIC (p<0.05), increase in MDF (p<0.05). Conclusion : From these results, active rnyotascial trigger points muscle showed quality deterioration on ultrasound imaging and decreased function of muscle contraction, increased motor unit action potential of II type fiber, and electrophysiologically. Imaging structure and neuromuscular physiological characteristic can be diagnostic and quantitative analytical techniques for myofascial pain syndrome and a primary factor that reflected in physical therapy intervention.

The aim of this study was to determine the immediate effects of single treatment of strain-counter strain (SCS) on pressure pain threshold (PPT) and muscle activity during scapular plane abduction with 3% body weight load. Fifteen asymptomatic male adults with upper trapezius latent trigger point (LTrP) (PPT<2.9 $kg/cm^2$) participated in this study. Pressure algometer was used to measure PPT and surface electromyography was used to record upper, middle arid lower trapezius, serratus anterior, infraspinatus and middle deltoid muscle activity and relative ratio during scapular plane abduction between pre- and post-intervention. There was a significant increase in upper trapezius PPT after a 90-second SCS (p<.05). The activity of the upper trapezius and middle deltoid was significantly decreased (p=.014, p=.001), coupled with a decreased muscle activity ratio between the upper and lower trapezius (p<.05). These results indicate that the SCS may effectively deactivate upper trapezius activity, thereby alleviating muscle balance and reducing pain sensitivity.

The aim of our study was to evaluate the immediate effects of an 830-nm Aluminium gallium arsenide (GaAlAs) laser, by examining the changes, in pressure-pain threshold (PPT) and tenderness at 3 kg of the myofascial trigger point (MTrP) of the upper trapezius muscle in visual display terminal (VDT) workers in comparison with placebo treatment. Thirty VDT workers (13 males, 17 females) with complaints of upper trapezius muscle were recruited. All participants were given either active GaAlAs laser (830 nm wavelength, 450 mW, 9 J at point) or placebo GaAlAs laser, according to the double-blinded and placebo-controlled trial. Both active and placebo low-level laser therapy (LLLT) treatments showed no significant effect on PPT and tenderness at 3 kg. These results suggest that a higher dosage may be necessary to produce immediate effects when applying LLLT to the MTrP of relatively large muscles such as the upper trapezius muscle.

A migraine is a recurrent, throbbing headache generally felt on one side of the head. Migraines usually begin in early childhood, adolescence, or young adult life. Its accurate pathogenesis is still unknown but migraines are caused by a rapid widening and narrowing of blood vessel walls in the brain and head. The classic migraine and the common migraine are the two main types. The onset of classical migraine may be signalled by visual disturbances in what is called the 'aura' stage. Visual aura is most common among the auras of classical migraine. Common migraine (or migraine without aura) and classical migraine may be accompanied by various combinations of symptoms such as nausea, vomiting, and sensitivity to light and sound. Recently we have exprienced 2 cases of migraine patients and whose conditions were improved through trigger point needling and Oriental medical treatment.

Myofascial pain syndrome is one of the pain syndrome resulted from myofascia which covered muscles and clinically characteristic feature by sensitive trigger point in skeletal muscles and referred pain reactivated by stimulating each trigger point. The origin of headache are local lesion such as head, chest, abdominal organ, systemic lesion with fever or in toxic state. the other factors are consciousness, personality, anxiety, depression, which cause muscle strain in physiological environment. The Oriental Medical therapy for headache has herb medication and acupuncture. especially acupuncture therapy has not only classical systemic acupuncture(體鍼) but also neo-acupuncture(新鍼) such as commonly using auricular acupuncture(耳鍼) and manual acupuncture (手鍼), recently trigger point acupuncture is used. The author analyzed 27 cases of patient with headache treated by trigger point acupuncture therapy in Dong-yu Oriental Medical Hospital from March 1st 1997 to February 28th 1998. The following results were obtained. 1. The sex ratio of the female was 59.26%(16 cases) and male was 40.74%(11 cases), the ratio of high school student was 62.96%(17cases) as first. 2. The headache duration ratio of 2-3 years was 37.04%(10 cases) as first, 1-2 years was 25.93%(7 cases) as second. 3. The portion ratio of whole headache was 33.33%(9 cases) as first, lateral headache was 29.63%(8 cases) as second 4. The combined symptoms ratio of anorexia was 40.74%(11 cases) as first, fatigue was 33.33%(9 cases) as second, neck stiffness and dizziness was each 25.93%(7 cases) as third. 5.

Objective: This study aimed to investigate the effects of ischemic compression treatment (ICT) or low-level laser therapy (LLLT) applied to the trigger points of the infraspinatus muscle on shoulder pain and function in patients with shoulder pain. Design: A randomized clinical trial Methods: Thirty patients with shoulder pain were randomly allocated into the ICT group (n=15) or LLLT groups (n=15). ICT was performed on three myofascial trigger points (MTrPs) of the infraspinatus muscle twice a week for 4 weeks (eight sessions), with 5 minutes of treatment per trigger point. LLLT was performed similarly. Shoulder pain was assessed using the visual analogue scale (VAS) and pain pressure threshold (PPT), and shoulder function was assessed using the Korean Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire, rotator cuff strength, and range of motion (ROM) of shoulder flexion and abduction. Results: Significant changes in VAS score and PPT were found after the intervention in both groups (p<0.05). Significant changes were observed in the Korean DASH score, rotator cuff strength, and ROM of shoulder flexion (p<0.05) but not in the ROM of shoulder abduction (p<0.05). There were no significant differences between the two groups. Conclusions: This study showed that both ICT and LLLT applied on the MTrPs of the infraspinatus muscle were effective for relieving shoulder pain and improving shoulder functions in patients with shoulder pain.
