Impact of Experimental Tonic Pain on Corrective Motor Responses to Mechanical Perturbations

Table 1

of normalized RMS EMG (%MVC) in No pain and Pain sessions during SL, LL, and EV responses for BB (a) and TB (b) muscles in P, VPc, VPi, and V conditions. The column “mean” represents the mean of normalized RMS EMG in experimental trials (P, VPc, and VPi). Statistically significant results from the Wilcoxon test comparing RMS EMG within each time window between conditions with (average of P, VPc, and VPi) and without (V) mechanical perturbation are identified by an asterisk (<0.05, <0.01, and <0.001).
