title: Wrist clonus mimicking as action-induced tremors: an important clinical lesson.
abstract: We report a 35-year-old man who presented with abnormal movement of hand upon extension at wrist joint in an outstretched arm. He was diagnosed and treated elsewhere as having action-induced tremors. On examination, he had action-induced clonus at wrist joint with bilateral corticospinal tract features in the form of weakness, spasticity and extensor plantars. Evaluation also revealed cervical compressive myelopathy. The purpose of presenting this case report is to highlight this rare clinical sign which can be mistaken for action-induced tremors.
