Mean values ( ± SD) of mechanical and EMG variables during voluntary contractions at 60% MVC in the two groups. The results of the non parametric Mann-Whitney U test (in bold those significant) are reported. MCG = Matched Control Group, FM = Fibromyalgic Group, MVC = maximal voluntary contraction, CV = conduction velocity, MNF = mean spectral frequency, ARV = average rectified value; NS = non significative |
