Sigmoid function parameters.

Summarized sigmoid function parameters calculated from the sigmoid fit applied to the MEP and TEP recruitment curve for each subject and muscle. The first column indicates the maximum size of the action potentials from the recruitment curve (in mV ms), while the second column indicates the R2 from the sigmoid function. No statistically significant differences were found between the sigmoidal parameters between MEPs and TEPs, across muscles, or between TEPs recorded from the left or right leg (P>0.05). m: slope parameter of the function, S50: stimulus at 50% of the maximal evoked compound action muscle potential. R: right. L: left. TA: tibialis anterior. MG: medialis gastrocnemius. SOL: soleus. PL: peroneus longus.
