Electromyography (EMG)
SKIN
Surface EMG was used to record MEPs from the first dorsal interosseous (FDI) muscle of the non-paretic hand, with adhesive disposable EMG electrodes positioned in a belly-tendon montage (22 × 34 mm, FIAB, Florence, Italy). Skin overlying the FDI muscle was cleaned using an alcohol wipe prior to electrode application. A ground strap was placed on the wrist. Participants were seated in a standard chair with the contralesional arm resting on their lap in a pronated position.
