The secondary objective was to assess the intra\u2010rater reliability of standard timed motor tests and dyskinesia scales to determine the necessity of multiple baseline core evaluations before surgery for PD. We carried out two standardized preoperative core evaluations of patients with advanced PD scheduled to undergo deep brain stimulation. Patients were examined in the defined <jats:italic>off<\/jats:italic> and <jats:italic>on<\/jats:italic> conditions by the same rater. UPDRS\u2010III, timed tests, and dyskinesia scores from the two evaluations were compared using Wilcoxon Signed Ranks tests and intraclass correlation coefficients (ICC). Differences in UPDRS\u2010III scores for the two visits were clinically and statistically nonsignificant, and the ICC was 0.9. Similarly, there were no significant differences in timed motor tests or dyskinesia scores, with a median ICC of 0.8. The results indicate that previous findings of high test\u2013retest reliability of UPDRS\u2010III in early untreated PD patients can now be extended to those with advanced disease complicated by motor fluctuations. In addition, test\u2013retest reliability of dyskinesia scales and timed motor tests was high. Taken together, these findings challenge the need for multiple baseline assessments as currently stipulated in core assessment protocols for surgical intervention in PD. \u00a9 2004 Movement Disorder Society<\/jats:p>","DOI":"10.1002\/mds.20101","type":"journal-article","created":{"date-parts":[[2004,4,13]],"date-time":"2004-04-13T08:23:09Z","timestamp":1081844589000},"page":"1079-1084","source":"Crossref","is-referenced-by-count":55,"title":["Test\u2013retest reliability of UPDRS\u2010III, dyskinesia scales, and timed motor tests in patients with advanced Parkinson's disease: An argument against multiple baseline assessments"],"prefix":"10.1002","volume":"19","author":[{"given":"Leo Verhagen","family":"Metman","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Brian","family":"Myre","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Niek","family":"Verwey","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sharon","family":"Hassin\u2010Baer","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jean","family":"Arzbaecher","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Diane","family":"Sierens","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Roy","family":"Bakay","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2004,8,30]]},"reference":[{"key":"e_1_2_6_2_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-0404.2007.00818.x"},{"key":"e_1_2_6_3_2","doi-asserted-by":"publisher","DOI":"10.1002\/mds.870090114"},{"key":"e_1_2_6_4_2","doi-asserted-by":"publisher","DOI":"10.1002\/mds.870090113"},{"key":"e_1_2_6_5_2","doi-asserted-by":"publisher","DOI":"10.1002\/mds.870090112"},{"key":"e_1_2_6_6_2","doi-asserted-by":"publisher","DOI":"10.1002\/mds.870130404"},{"key":"e_1_2_6_7_2","doi-asserted-by":"publisher","DOI":"10.1002\/mds.10011"},{"key":"e_1_2_6_8_2","doi-asserted-by":"publisher","DOI":"10.1002\/mds.870070103"},{"key":"e_1_2_6_9_2","doi-asserted-by":"publisher","DOI":"10.1002\/1531-8257(199907)14:4<572::AID-MDS1005>3.0.CO;2-C"},{"key":"e_1_2_6_10_2","first-page":"534","volume-title":"ECDEU assessment manual for psychopharmacology","author":"Guy W","year":"1976"},{"key":"e_1_2_6_11_2","doi-asserted-by":"publisher","DOI":"10.1002\/mds.870090403"},{"key":"e_1_2_6_12_2","doi-asserted-by":"publisher","DOI":"10.1002\/mds.870100305"},{"key":"e_1_2_6_13_2","first-page":"212","volume-title":"Statistical methods for rates and proportions","author":"Fleiss JL","year":"1981"},{"key":"e_1_2_6_14_2","doi-asserted-by":"publisher","DOI":"10.1212\/WNL.36.6.739"},{"key":"e_1_2_6_15_2","doi-asserted-by":"publisher","DOI":"10.1212\/WNL.49.3.711"},{"key":"e_1_2_6_16_2","doi-asserted-by":"publisher","DOI":"10.1002\/mds.10149"}],"container-title":["Movement Disorders"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1002%2Fmds.20101","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/movementdisorders.onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/mds.20101","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,10,20]],"date-time":"2025-10-20T11:37:50Z","timestamp":1760960270000},"score":1,"resource":{"primary":{"URL":"https:\/\/movementdisorders.onlinelibrary.wiley.com\/doi\/10.1002\/mds.20101"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2004,8,30]]},"references-count":15,"journal-issue":{"issue":"9","published-print":{"date-parts":[[2004,9]]}},"alternative-id":["10.1002\/mds.20101"],"URL":"https:\/\/doi.org\/10.1002\/mds.20101","archive":["Portico"],"relation":{},"ISSN":["0885-3185","1531-8257"],"issn-type":[{"value":"0885-3185","type":"print"},{"value":"1531-8257","type":"electronic"}],"subject":[],"published":{"date-parts":[[2004,8,30]]}}}
