  1. aPulsed mode, 3 MHz, 2.5 W/cm2, 5 min.; bcontinuous mode, 1 MHz, 0.8 W/cm2, 3 min. Control-p no US therapy in pulsed US group; Control-c no US therapy in continuous US group, Tx treatment, M mean, CI 95% confidence interval, SD standard deviation, CS change scores, ES effect size r (pre-post/pooled SD). Aβ = R-CPT at 2,000 Hz; C = R-CPT at 5 Hz; R-CPT ranged current perception threshold test. *Significance level at p < 0.05.
