Values are Pearson’s correlation coefficient (r) used to examine the relationship between various transcranial magnetic stimulation (TMS) and electromyographic (EMG) measures in soleus (SOL) and tibialis anterior (TA) muscles. bEMG, background EMG; SICI, short-interval intracranial inhibition. Values in parentheses indicate R2 for each correlation.
*
Significant correlation.
