Interlimb asymmetries of ratio MQREL. Displayed are the 95% confidence intervals of the side differences of the arithmetic mean of the specific ratio Qrel (Asym-MQREL) of the MMGs and the ACC signals. As can be seen in the MMG-signals of the elbow flexors, the PD have a higher side difference compared to the controls (p = 0.008; p = 0.048). In the MMGpect, a tendency of higher side asymmetry in PD is visible, whereas the ACC-signal show no difference between PD and Con.
