This study was designed to determine the sensitivity, specificity, and receiver operating characteristic (ROC) curve of the MPT for diagnosis of CTS.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Electrodiagnostic nerve conduction studies (EDS) were used as the gold standard. MPT was performed by a blinded examiner on patients prior to EDS. MPT was recorded as either positive or negative based on the presence or absence of a median nerve sensory deficit while the hand was in Phalen's position.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Sixty\u2010six hands were included in this study. Chi\u2010square for the MPT compared to EDS as the gold standard was 41.449 (<jats:italic>P<\/jats:italic> &lt; 0.001), and the validity coefficient (phi) was 0.792 (<jats:italic>P<\/jats:italic> &lt; 0.01). The traditional Phalen's test (TPT) compared to the EDS demonstrated a chi\u2010square of 15.349 (<jats:italic>P<\/jats:italic> &lt; 0.001) and a phi coefficient of 0.482 (<jats:italic>P<\/jats:italic> &lt; 0.01). ROC curve estimates for the MPT revealed a sensitivity of 84.4% compared to 50% for the TPT. The standard error of the estimate for sensitivity was 3.3% for the MPT and 5.8% for the TPT.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>The MPT is a highly useful screening diagnostic tool for CTS. The MPT demonstrates greater accuracy than the TPT for predicting CTS. The MPT also demonstrates greater sensitivity than the TPT in predicting a positive electrodiagnostic test for CTS.<\/jats:p><\/jats:sec>","DOI":"10.1002\/acr.20664","type":"journal-article","created":{"date-parts":[[2011,10,3]],"date-time":"2011-10-03T10:59:50Z","timestamp":1317639590000},"page":"287-289","source":"Crossref","is-referenced-by-count":9,"title":["Modified Phalen's test as an aid in diagnosing carpal tunnel syndrome"],"prefix":"10.1002","volume":"64","author":[{"given":"Sayeeda","family":"Bilkis","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Donald M.","family":"Loveman","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"James A.","family":"Eldridge","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shabnam Asgher","family":"Ali","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Abdul","family":"Kadir","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Walter","family":"McConathy","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2012,1,25]]},"reference":[{"key":"e_1_2_6_2_2","doi-asserted-by":"crossref","first-page":"115","DOI":"10.1016\/S0030-5898(20)30335-7","article-title":"Carpal tunnel syndrome: a scientific basis for clinical care","volume":"19","author":"Gelberman RH","year":"1988","journal-title":"Orthop Clin North Am"},{"key":"e_1_2_6_3_2","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-199911000-00013"},{"key":"e_1_2_6_4_2","doi-asserted-by":"publisher","DOI":"10.1002\/mus.880161220"},{"key":"e_1_2_6_5_2","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-198668050-00015"},{"key":"e_1_2_6_6_2","doi-asserted-by":"publisher","DOI":"10.1093\/rheumatology\/25.4.388"},{"key":"e_1_2_6_7_2","doi-asserted-by":"publisher","DOI":"10.7326\/0003-4819-112-5-321"},{"key":"e_1_2_6_8_2","first-page":"643","article-title":"Electrolingual correlation in the carpal tunnel syndrome: apropos of 100 cases","volume":"54","author":"Seror P","year":"1987","journal-title":"Rev Rhum Mal Osteortic"},{"key":"e_1_2_6_9_2","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-198466010-00009"},{"key":"e_1_2_6_10_2","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-198365050-00008"},{"key":"e_1_2_6_11_2","doi-asserted-by":"crossref","first-page":"157","DOI":"10.1097\/00003086-199002000-00025","article-title":"Carpal tunnel syndrome: evaluation of a quantitative prevocational diagnostic test","volume":"251","author":"Koris M","year":"1990","journal-title":"Clin Orthop Relat Res"},{"key":"e_1_2_6_12_2","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-199173040-00009"}],"container-title":["Arthritis Care &amp; Research"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1002%2Facr.20664","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/acrjournals.onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/acr.20664","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,10,2]],"date-time":"2025-10-02T14:23:02Z","timestamp":1759414982000},"score":1,"resource":{"primary":{"URL":"https:\/\/acrjournals.onlinelibrary.wiley.com\/doi\/10.1002\/acr.20664"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2012,1,25]]},"references-count":11,"journal-issue":{"issue":"2","published-print":{"date-parts":[[2012,2]]}},"alternative-id":["10.1002\/acr.20664"],"URL":"https:\/\/doi.org\/10.1002\/acr.20664","archive":["Portico"],"relation":{},"ISSN":["2151-464X","2151-4658"],"issn-type":[{"type":"print","value":"2151-464X"},{"type":"electronic","value":"2151-4658"}],"subject":[],"published":{"date-parts":[[2012,1,25]]}}}
