Reported is the number of evoked responses by condition in each subject. The number of subjects by session is indicated in column 3 (n). MI, motor imagery; FCR, flexor carpi radialis; MEP, motor-evoked potential; Mmax, maximal M wave; CMEP, cervico-medullary-evoked potential; H-reflex, Hoffmann-reflex; SOL, soleus; MG, medial gastrocnemius; LG, lateral gastrocnemius. Unmatched responses in column 1 represent maximal response amplitudes recorded at rest in static conditions. Matched responses represent the recordings with the adjusted stimulation intensity to match similar amplitude at rest among conditions (lengthening, shortening, and static).
