However, the reliability of this tool has rarely been evaluated and its use in a multicenter study has never been assessed prospectively.<\/jats:p><\/jats:sec><jats:sec><jats:title>Purpose<\/jats:title><jats:p>To evaluate the concordance between three unblinded clinical raters and one single\u2010blinded rater for 10 prospective series of ratings on the BFM scale in 22 dystonic patients of the SPIDY study.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Ten assessments on the BFM scale were performed under various stimulation conditions at different time points (before surgery and 1, 3, 6, and 12 months afterwards). Patients were first evaluated by three unblinded clinical raters (one per center). All assessments were videotaped and sent to a blinded rater. Intra\u2010 and inter\u2010rater reliability was assessed using intraclass correlation coefficients.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The intra\u2010rater reliability at inclusion was better for the blinded rater than for the clinical raters. The inter\u2010rater reliability (comparing the blinded rater with each clinical rater) was \u201cvery good\u201d at inclusion, \u201cfair\u201d at month 1 and was \u201cgood\u201d at month 3, month 6, and month 12.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Blinding (rather than video) is probably the key factor in better intra\u2010rater reliability and can produce more accurate rating than clinical rating. Consequently, a blind procedure should be performed systematically in multicenter studies. As inter\u2010rater reliability is good in trained unblinded raters, the BFM scale may also be used in the follow up of dystonic patients in movement disorders centers, in clinical practice. \u00a9 2007 Movement Disorder Society<\/jats:p><\/jats:sec>","DOI":"10.1002\/mds.21392","type":"journal-article","created":{"date-parts":[[2007,2,3]],"date-time":"2007-02-03T03:42:57Z","timestamp":1170474177000},"page":"685-689","source":"Crossref","is-referenced-by-count":66,"title":["Reliability of the Burke\u2010Fahn\u2010Marsden scale in a multicenter trial for dystonia"],"prefix":"10.1002","volume":"22","author":[{"given":"Pierre","family":"Krystkowiak","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sophie Tezenas","family":"du Montcel","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Laurent","family":"Vercueil","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jean\u2010Luc","family":"Houeto","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christelle","family":"Lagrange","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Philippe","family":"Cornu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Serge","family":"Blond","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alim\u2010Louis","family":"Benabid","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pierre","family":"Pollak","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marie","family":"Vidailhet","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"name":"The SPIDY Group (French Pallidal Stimulation Group for Dystonia)","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2007,4,25]]},"reference":[{"key":"e_1_2_7_2_2","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMoa042187"},{"key":"e_1_2_7_3_2","doi-asserted-by":"publisher","DOI":"10.1212\/WNL.35.1.73"},{"key":"e_1_2_7_4_2","doi-asserted-by":"publisher","DOI":"10.1002\/mds.10377"},{"key":"e_1_2_7_5_2","doi-asserted-by":"publisher","DOI":"10.1002\/mds.870130415"},{"key":"e_1_2_7_6_2","doi-asserted-by":"publisher","DOI":"10.1002\/1531-8257(199907)14:4<652::AID-MDS1015>3.0.CO;2-G"},{"key":"e_1_2_7_7_2","doi-asserted-by":"publisher","DOI":"10.1002\/1531-8257(200011)15:6<1242::AID-MDS1028>3.0.CO;2-Z"},{"key":"e_1_2_7_8_2","doi-asserted-by":"publisher","DOI":"10.1007\/s004150170116"},{"key":"e_1_2_7_9_2","doi-asserted-by":"publisher","DOI":"10.3171\/jns.2004.101.2.0189"},{"key":"e_1_2_7_10_2","doi-asserted-by":"publisher","DOI":"10.1016\/0920-9964(95)00096-8"},{"key":"e_1_2_7_11_2","first-page":"408","article-title":"Measuring agreement between 2 observers: a quantitative case","volume":"32","author":"Fermanian J","year":"1984","journal-title":"Rev Epidemiol Sante Publique"},{"key":"e_1_2_7_12_2","series-title":"Encyclopedia of biostatistics","first-page":"3123","author":"De Vet H","year":"1998"}],"container-title":["Movement Disorders"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1002%2Fmds.21392","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/movementdisorders.onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/mds.21392","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,10,20]],"date-time":"2025-10-20T11:06:34Z","timestamp":1760958394000},"score":1,"resource":{"primary":{"URL":"https:\/\/movementdisorders.onlinelibrary.wiley.com\/doi\/10.1002\/mds.21392"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2007,4,15]]},"references-count":11,"journal-issue":{"issue":"5","published-print":{"date-parts":[[2007,4,15]]}},"alternative-id":["10.1002\/mds.21392"],"URL":"https:\/\/doi.org\/10.1002\/mds.21392","archive":["Portico"],"relation":{},"ISSN":["0885-3185","1531-8257"],"issn-type":[{"value":"0885-3185","type":"print"},{"value":"1531-8257","type":"electronic"}],"subject":[],"published":{"date-parts":[[2007,4,15]]}}}
