Effects of sensory-level high-volt pulsed electrical current ondelayed-onset muscle soreness . Ten healthy males and ten healthy females aged 21.5 +/- 3.2 years ( mean +/- s ) participated in the study , which was designed to evaluate the effectiveness of sensory level-high volt pulsed electrical current ( HVPC ) on delayed-onset muscle soreness ( DOMS ) . Arm discomfort , elbow extension range of motion and isometric elbow flexion strength were obtained as baseline measurements . Delayed-onset muscle soreness was induced in the participants ' dominant or non-dominant arm using two sets of 20 maximal eccentric elbow flexion contractions . After the induction of DOMS , the participants were randomly divided into an experimental condition ( HVPC ) or a placebo condition . The experimental condition consisted of 20 min of HVPC immediately after the induction of DOMS , and 20 min every 24 h for three consecutive days thereafter . The participants in the placebo condition received an intervention similar in design ; however , no electrical current was administered . Baseline measurements were reevaluated at 24 , 48 , 72 and 96 h after the induction of DOMS . Three weeks later , the participants returned and the protocol was repeated on the contralateral limb , using the opposite intervention ( HVPC or placebo ) . Repeated-measures analysis of variance revealed a significant increase in overall arm discomfort , decrease in elbow extension and decrease in isometric strength for both conditions over time . No significant main effect of treatment , or time-by-treatment interaction , was found for the HVPC condition when compared with the placebo condition for any variable . Sensory-level HVPC , as utilized in our application , was ineffective in reducing the measured variables associated with DOMS .
