Fig. 4From: Technical development of transcutaneous electrical nerve inhibition using medium-frequency alternating currentMean finger force by phase in each experimental condition. Data are presented as mean ± standard deviation of force, normalized by the maximal voluntary contraction (%MVC) of corresponding fingers for each participant. Virtual finger force indicates the sum of the index and middle finger forces. *: significantly lower force in Phase 2 than that of Phases 1 or 3 (p < 0.05, Duncan’s new multiple range test)Back to article page
