Abstract

Objective : This study was performed to confirm the effects of acupuncture on myofascial pain syndrome(MPS) through the change of visual analogue scale(VAS) and pain pressure threshold(PPT) and the usefulness of pressure algometer on the evaluation of pain. Methods : We perfomed this study with 20 outpatients complaining of upper back pain. Before acupuncture therapy(AT), immediately after AT and 2-3 days after AT, we respectively checked visual analogue scale(VAS) and pain pressure threshold(PPT) through pressure algometer, with patients seated and relaxed. The PPT was checked at major trigger point of upper trapezius, levator scapulae, supraspinatus, infraspinatus, rhomboideus minor. and the patients were needled at the same points and maintained for 15 minutes. Results : VAS of immediately after AT was mild higher than that of before AT, but not significantly different. and VAS of 2-3 days after AT was significantly lower than before AT and immediately after AT. PPT of immediately after AT was lower than before PT, but not significantly different. PPT of 2-3 days after AT was significantly higher than that of before AT and immediately after AT. Also PPT was significantly correlated with VAS. Conclusion : PPT of omen was signicantly lower than that of men. and there was no significant difference by age. PPT was increased according to pain duration. Effectiveness of acupuncture on myofascial pain syndrome through PPT and VAS is showed at 2-3 days after AT rather than immediatly after AT. and pressure algometer is useful for the evaluation of Acupuncture therapy on myofascial pain syndrome.
