Surface electromyography analysis of contralateral lower extremity tremor following thalamic hemorrhage
Although there are various movement disorders that can develop after thalamic stroke, isolated tremors confined to the lower extremities are rare, and their pathophysiological mechanism is unclear . Here, we present a case of delayed-onset, regular, transient tremor following thalamic hemorrhage, which we confirm using surface electromyography (EMG).

Video legend A 59-year-old woman experienced a right thalamic hemorrhage. Two months after the stroke, she developed a combination of rest and postural tremor at a low frequency in her left lower limb. At the time of recording, the patient was not taking any medication in relation to the tremor. (Informed consent about the video script was obtained from the patient.) (WMV 8216 kb)
