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.
