A: Transcranial magnetic stimulation (TMS) of the left primary motor area (M1) induced a contralateral motor‐evoked potential (MEP) (on the right abductor pollicis brevis [APB]) and an ipsilateral MEP (on the left APB). The mean amplitude of the ipsilateral MEP was larger than that of the contralateral MEP. Representative recorded MEPs are shown.B: Polygraph recordings from the right and left flexor digitorum superficialis (FDS) and extensor digitorum communis (EDC) were obtained while the patient was performing self‐paced, repetitive flexion‐extension movements of the fingers of the left hand. Simultaneous electromyogram (EMG) activity compatible with mirror movement (MM) was present on the right flexor digitorum superficialis (FDS) and extensor digitorum communis (EDC) before Botulinum toxin (BoNT) treatment. After BoNT treatment, the amplitude of the EMG bursts in the right FDS was decreased; and, overall, there was less EMG activity in the right EDC.
