Clinical information including age, gender, presence of deformity, initial symptom side, neuropsychological and motor features, family history, and treatment with levodopa\/dopamine agonists was collected on consecutive patients with PD, MSA, and PSP evaluated at the Movement Disorders Clinic at Baylor College of Medicine. In this series of 202 patients, 36.1% had deformities of the limbs, neck, or trunk, including 33.5% of PD, 68.4% of MSA, and 26.3% of PSP patients. \u201cStriatal\u201d hand and foot deformities were present in 13.4%, involuntary trunk flexion in 12.9%, anterocollis in 9.4%, and scoliosis in 8.4% of all patients. Patients with these joint and skeletal deformities had higher mean Unified Parkinson's Disease Rating Scale scores (57.4 vs. 46.6; <jats:italic>P<\/jats:italic> &lt; 0.01) and were more often treated with levodopa (69.9% vs. 50.4%; <jats:italic>P<\/jats:italic> &lt; 0.01) than patients without deformity, independent of disease duration. Patients with striatal deformity were younger than patients without deformity (mean 60.4 vs. 68.6 years; <jats:italic>P<\/jats:italic> &lt; 0.01), and they tended to have an earlier age of onset of initial parkinsonian symptoms (mean 54.7 vs. 62.5 years; <jats:italic>P<\/jats:italic> &lt; 0.01). Furthermore, the side of striatal deformity correlated with the side of initial parkinsonian symptoms in all patients (100%) with striatal hand and in 83.3% of patients with striatal foot. Joint and skeletal deformities are common and frequently under\u2010recognized features of PD, MSA, and PSP that often cause marked functional disability independent of other motor symptoms. \u00a9 2006 Movement Disorder Society<\/jats:p>","DOI":"10.1002\/mds.21058","type":"journal-article","created":{"date-parts":[[2006,8,28]],"date-time":"2006-08-28T15:59:47Z","timestamp":1156780787000},"page":"1856-1863","source":"Crossref","is-referenced-by-count":190,"title":["Joint and skeletal deformities in Parkinson's disease, multiple system atrophy, and progressive supranuclear palsy"],"prefix":"10.1002","volume":"21","author":[{"given":"Ramsey","family":"Ashour","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joseph","family":"Jankovic","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2006,8,28]]},"reference":[{"key":"e_1_2_7_2_2","doi-asserted-by":"publisher","DOI":"10.1001\/archneur.56.1.33"},{"key":"e_1_2_7_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0022-510X(98)00304-9"},{"key":"e_1_2_7_4_2","doi-asserted-by":"publisher","DOI":"10.1212\/WNL.47.1.1"},{"key":"e_1_2_7_5_2","doi-asserted-by":"publisher","DOI":"10.1136\/jnnp.52.1.63"},{"key":"e_1_2_7_6_2","doi-asserted-by":"publisher","DOI":"10.1136\/bmj.331.7530.1453"},{"key":"e_1_2_7_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0895-4356(99)00145-6"},{"key":"e_1_2_7_8_2","doi-asserted-by":"publisher","DOI":"10.1097\/00006534-200007000-00024"},{"key":"e_1_2_7_9_2","doi-asserted-by":"publisher","DOI":"10.1097\/00006416-200503000-00014"},{"key":"e_1_2_7_10_2","doi-asserted-by":"publisher","DOI":"10.1097\/00043764-200005000-00012"},{"key":"e_1_2_7_11_2","doi-asserted-by":"publisher","DOI":"10.1136\/bmj.331.7507.30"},{"key":"e_1_2_7_12_2","doi-asserted-by":"crossref","first-page":"94","DOI":"10.1177\/107110070002100202","article-title":"Operative repair of the fixed hammertoe deformity","volume":"21","author":"Coughlin M","year":"2000","journal-title":"Foot Ankle Int"},{"key":"e_1_2_7_13_2","doi-asserted-by":"publisher","DOI":"10.1093\/aje\/kwh071"},{"key":"e_1_2_7_14_2","doi-asserted-by":"publisher","DOI":"10.1302\/0301-620X.84B7.12811"},{"key":"e_1_2_7_15_2","doi-asserted-by":"publisher","DOI":"10.1016\/S1474-4422(05)70119-8"},{"key":"e_1_2_7_16_2","doi-asserted-by":"publisher","DOI":"10.1212\/WNL.40.10.1571"},{"key":"e_1_2_7_17_2","doi-asserted-by":"publisher","DOI":"10.1002\/mds.870120203"},{"key":"e_1_2_7_18_2","doi-asserted-by":"publisher","DOI":"10.1136\/jnnp.52.Suppl.78"},{"key":"e_1_2_7_19_2","doi-asserted-by":"publisher","DOI":"10.1212\/WNL.37.9.1546"},{"key":"e_1_2_7_20_2","first-page":"293","article-title":"Progressive supranuclear palsy: motor, neurobehavioural and neuro\u2010ophthalmological findings","volume":"53","author":"Jankovic J","year":"1990","journal-title":"Adv Neurol"},{"key":"e_1_2_7_21_2","doi-asserted-by":"publisher","DOI":"10.1136\/jnnp.62.4.352"},{"key":"e_1_2_7_22_2","doi-asserted-by":"publisher","DOI":"10.1002\/mds.1038"},{"key":"e_1_2_7_23_2","doi-asserted-by":"publisher","DOI":"10.1212\/WNL.35.2.227"},{"key":"e_1_2_7_24_2","first-page":"167","volume-title":"Handbook of Clinical Neurology, Extrapyramidal Disorders","author":"Chen K","year":"1986"},{"key":"e_1_2_7_25_2","first-page":"140","volume-title":"Lectures on the Diseases of the Nervous System.
