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.<\/jats:p>","DOI":"10.1136\/bcr-2012-006804","type":"journal-article","created":{"date-parts":[[2012,12,6]],"date-time":"2012-12-06T12:48:43Z","timestamp":1354798123000},"page":"bcr2012006804","source":"Crossref","is-referenced-by-count":5,"title":["Wrist clonus mimicking as action-induced tremors: an important clinical lesson"],"prefix":"10.1136","volume":"2012","author":[{"given":"Bhawna","family":"Sharma","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Raghavendra Bakki","family":"Sannegowda","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kadam","family":"Nagpal","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rahul","family":"Jain","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2012,12,6]]},"reference":[{"key":"2025042707474890000_2012.dec06_1.bcr2012006804.1","unstructured":"Ropper AH Samuels MA .
