OBJECTIVE: This study proposes a revised approach for classifying the severity of electrophysiological findings for patients with CTS. METHODS: This retrospective cross-sectional study included patients with CTS confirmed through electrodiagnostic evaluations. Based on the Stevens\u2019 classification, the patients were divided into three groups (mild\/moderate\/severe). A new intermediate group was defined to identify patients with normal motor nerve conduction studies and abnormal electromyographic results. CTS pain was evaluated using a numeric rate scale. Physical examinations and sonographic evaluation were performed to detect anatomical abnormalities. RESULTS: Overall, 1,069 CTS hands of 850 CTS patients were included. The mean age was 57.9 \u00b1 10.8\u00a0years, and 336 (39.5%) were men. There were 522 (48.8%) mild cases; 281 (26.3%) moderate cases; and 266 (24.9%) severe cases. In the severe group, 49 cases were reclassified into the intermediate group. The median cross-sectional area in the intermediate group significantly differed from that in the severe group. However, the pain score significantly differed from that of the moderate group. CONCLUSION: The intermediate CTS group showed clinical features that were intermediate to those of the moderate and severe CTS groups.<\/jats:p>","DOI":"10.3233\/bmr-230275","type":"journal-article","created":{"date-parts":[[2024,4,2]],"date-time":"2024-04-02T13:56:49Z","timestamp":1712066209000},"page":"1205-1212","source":"Crossref","is-referenced-by-count":1,"title":["A revised electrodiagnosis-based severity classification for carpal tunnel syndrome"],"prefix":"10.1177","volume":"37","author":[{"given":"Do Hun","family":"Jung","sequence":"first","affiliation":[{"name":"Department of Physical Medicine and Rehabilitation, National Health Insurance Service Ilsan Hospital, Goyang, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sang-Eok","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Rehabilitation Medicine, Pohang Stroke and Spine Hospital, Pohang, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dougho","family":"Park","sequence":"additional","affiliation":[{"name":"Department of Rehabilitation Medicine, Pohang Stroke and Spine Hospital, Pohang, Korea"},{"name":"Department of Medical Science and Engineering, School of Convergence Science and Technology, Pohang University of Science and Technology, Pohang, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jang Woo","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Physical Medicine and Rehabilitation, National Health Insurance Service Ilsan Hospital, Goyang, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","reference":[{"issue":"3","key":"10.3233\/BMR-230275_ref1","doi-asserted-by":"crossref","first-page":"255","DOI":"10.1016\/S1474-4422(22)00432-X","article-title":"Carpal tunnel syndrome: Updated evidence and new questions","volume":"22","author":"Padua","year":"2023","journal-title":"Lancet Neurol"},{"issue":"5","key":"10.3233\/BMR-230275_ref2","doi-asserted-by":"crossref","first-page":"495","DOI":"10.5271\/sjweh.3351","article-title":"Prevalence and incidence of carpal tunnel syndrome in US working populations: Pooled analysis of six prospective studies","volume":"39","author":"Dale","year":"2013","journal-title":"Scand J Work Environ Health"},{"issue":"8","key":"10.3233\/BMR-230275_ref3","first-page":"1654","article-title":"Multiperspective assessment of carpal tunnel syndrome: A multicenter study","volume":"53","author":"Padua","year":"1999","journal-title":"Italian CTS Study Group"},{"issue":"3","key":"10.3233\/BMR-230275_ref4","first-page":"e7333","article-title":"Carpal tunnel syndrome: A review of literature","volume":"12","author":"Genova","year":"2020","journal-title":"Cureus"},{"issue":"12","key":"10.3233\/BMR-230275_ref5","first-page":"993","article-title":"Carpal tunnel syndrome: Diagnosis and management","volume":"94","author":"Wipperman","year":"2016","journal-title":"Am Fam Physician"},{"issue":"4","key":"10.3233\/BMR-230275_ref6","doi-asserted-by":"crossref","first-page":"1089","DOI":"10.1007\/s11999-010-1637-5","article-title":"The sensitivity and specificity of ultrasound for the diagnosis of carpal tunnel syndrome: A meta-analysis","volume":"469","author":"Fowler","year":"2011","journal-title":"Clin Orthop Relat Res"},{"issue":"1","key":"10.3233\/BMR-230275_ref7","doi-asserted-by":"crossref","first-page":"63","DOI":"10.1136\/jnnp.2007.115337","article-title":"High-resolution sonography versus EMG in the diagnosis of carpal tunnel syndrome","volume":"79","author":"Visser","year":"2008","journal-title":"J Neurol Neurosurg Psychiatry"},{"key":"10.3233\/BMR-230275_ref8","doi-asserted-by":"crossref","unstructured":"Hern\u00e1ndez-Secor\u00fan M, Monta\u00f1a-Cort\u00e9s R, Hidalgo-Garc\u00eda C, Rodr\u00edguez-Sanz J, Corral-de-Toro J, Monti-Ballano S, et al.
