We investigated the presence of impaired MI in ET patients compared with healthy controls. A group of drug\u2010naive and nondemented ET patients and age\u2010matched controls were studied using transcranial magnetic stimulation, while they were specifically instructed to try and imagine themselves performing two motor tasks. The various clinical and electrophysiological variables were evaluated and compared. Repeated measures ANOVA demonstrated a significant difference between ET patients and controls with respect to mean motor\u2010evoked potential (MEP) amplitudes (<jats:italic>F<\/jats:italic>(1,38) = 31.92, <jats:italic>P<\/jats:italic> &lt; 0.005) during MI. The process of MI effectively facilitated MEP amplitude in controls but not in ET patients, regardless of side of stimulation or motor tasks. We provide evidence to demonstrate impairment of MI in a group of ET patients compared with healthy controls. The basis for this novel finding is unclear, and further studies are warranted to determine whether it is related to cerebellar or motor cortical dysfunction. \u00a9 2007 Movement Disorder Society<\/jats:p>","DOI":"10.1002\/mds.21356","type":"journal-article","created":{"date-parts":[[2007,1,16]],"date-time":"2007-01-16T21:14:12Z","timestamp":1168982052000},"page":"504-508","source":"Crossref","is-referenced-by-count":5,"title":["Impaired motor imagery in patients with essential tremor: A case control study"],"prefix":"10.1002","volume":"22","author":[{"given":"Yew\u2010Long","family":"Lo","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Elan D.","family":"Louis","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stephanie","family":"Fook\u2010Chong","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eng\u2010King","family":"Tan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2007,3,27]]},"reference":[{"key":"e_1_2_6_2_2","doi-asserted-by":"publisher","DOI":"10.1002\/mds.10221"},{"key":"e_1_2_6_3_2","doi-asserted-by":"publisher","DOI":"10.1212\/01.WNL.0000153481.30222.38"},{"issue":"3","key":"e_1_2_6_4_2","first-page":"43","article-title":"Overview of human tremor physiology","volume":"13","author":"Hallett M","year":"1998","journal-title":"Mov Disord"},{"key":"e_1_2_6_5_2","doi-asserted-by":"publisher","DOI":"10.1212\/01.WNL.0000065890.75790.29"},{"key":"e_1_2_6_6_2","doi-asserted-by":"publisher","DOI":"10.1002\/mus.880170716"},{"key":"e_1_2_6_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(00)04044-7"},{"key":"e_1_2_6_8_2","doi-asserted-by":"publisher","DOI":"10.1136\/jnnp.2004.037176"},{"key":"e_1_2_6_9_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.parkreldis.2005.04.007"},{"key":"e_1_2_6_10_2","doi-asserted-by":"publisher","DOI":"10.1093\/brain\/awg132"},{"key":"e_1_2_6_11_2","doi-asserted-by":"publisher","DOI":"10.1136\/jnnp.73.4.400"},{"key":"e_1_2_6_12_2","doi-asserted-by":"publisher","DOI":"10.1002\/ana.410410108"},{"key":"e_1_2_6_13_2","doi-asserted-by":"publisher","DOI":"10.1093\/cercor\/9.2.161"},{"key":"e_1_2_6_14_2","doi-asserted-by":"publisher","DOI":"10.1682\/JRRD.2004.04.0505"},{"key":"e_1_2_6_15_2","doi-asserted-by":"publisher","DOI":"10.1152\/jn.00132.2002"},{"key":"e_1_2_6_16_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0926-6410(02)00197-0"},{"issue":"3","key":"e_1_2_6_17_2","first-page":"2","article-title":"Consensus statement of the Movement Disorder Society on Tremor.
