Mixed model ANOVA results (Type III) ANOVAs using the Kenward-Roger approximation for degrees of freedom investigating the effect of each fixed factor on the beta-band motor unit coherence. The degrees of freedom (df) listed under df1/2 were rounded to the next integer. MFR, mean firing rate; MUnum, number of motor units used in the coherence calculation.
