Electromyography activities in root mean square (RMS) percentage for the SP9 (A) and ST36 (B) groups before and after acupuncture. Data were reported as mean ± SD. *Statistically significant differences, in comparison to the pre- and post-SP9 or ST36 treatment values, according to paired t-test (P = 0.001) in A and (P = 0.002) in B. N = 15 for each group, Pre: local and adjacent point groups before acupuncture, Post ST36 treatment: local point group after acupuncture, Post SP9 treatment: adjacent point group after acupuncture.
