Effects of Suspended Moxibustion on Delayed Onset Muscle Soreness: A Randomized Controlled Double-Blind Pilot Study.

The objective of this study was to investigate the effects of suspended moxibustion upon tender point on delayed onset muscle soreness. The study was a randomized double-blind controlled trial with 50 subjects in each group. Subjects in moxibustion group received suspended moxibustion upon tender point (by palpation) twice. The controls received no treatment. Each subject received treatments twice, 24 hr and 48 hr after the delayed onset muscle soreness induction. The measurements of Pain Visual Analog Scale, maximum isometric muscle strength and circumference were made immediately after delayed onset muscle soreness induction, before and after every treatment session and 72 hr after delayed onset muscle soreness induction. There were no significantly statistical differences between two groups at all measurement time points on maximum isometric muscle strength and circumference. However, the Pain Visual Analog Scale scores after first treatment session and 72 hr after delayed onset muscle soreness induction in moxibustion group was less than the control group, with significant difference (p < 0.05). The suspended moxibustion failed to show the effect on delayed onset muscle soreness. However, results need to be cautiously interpreted because of the pilot character of this study. The suspended moxibustion has a potential effect of pain relief on DOMS from the analysis of the data of this study. A large sample size trial is needed to confirm the effect of the suspended moxibustion on DOMS in the future.
