Diagnosis relies on the clinical criteria and exclusion of other probable causes. The purpose of this study is to determine the scope and new diagnostic value of magnetic resonance imaging (MRI) in identifying muscle involvement in PPS and distinguishing it from prior poliomyelitis (PPM). Methods: This study was approved by the Ko\u00e7 University Ethics Committee with Approval No. 2023.409.IRB2.090. Electronic medical archives from two academic institutions were searched for records tagged with ICD code B-91 for poliomyelitis sequalae. The resulting search query of 291 records was manually sorted for PPS and PPM, medical history, clinical examination findings, and lumbar MR images down to 32 patients. Two independent radiologists evaluated the paraspinal musculature in the MRIs using the Mercuri scale. Inter-rater agreement, comparison of the paraspinal musculatures between groups, and their relationship to leg involvement were assessed with the resulting data. Results: Inter-rater agreement was found to be almost perfect across all muscles, except for the multifidus muscle. When clinical examination findings were included for these muscles, quadratus lumborum (QL) degradation was found in both right-side (p = 0.017) and left-side (p = 0.002) leg involvement. Conclusions: QL muscle deterioration may serve as a diagnostic marker for PPS, potentially guiding lumbar pain treatment through rehabilitation.<\/jats:p>","DOI":"10.3390\/jcm13164828","type":"journal-article","created":{"date-parts":[[2024,8,16]],"date-time":"2024-08-16T04:29:57Z","timestamp":1723782597000},"page":"4828","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Differentiation of Post-Polio Syndrome from Prior Poliomyelitis Sequela by Assessing Paraspinal Muscle Involvement in Magnetic Resonance Imaging"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9364-4512","authenticated-orcid":false,"given":"Mahir","family":"Topaloglu","sequence":"first","affiliation":[{"name":"Department of Physical Medicine and Rehabilitation, Ko\u00e7 University School of Medicine, 34450 Istanbul, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4922-5847","authenticated-orcid":false,"given":"Deniz","family":"Sarikaya","sequence":"additional","affiliation":[{"name":"Department of Physical Medicine and Rehabilitation, Ko\u00e7 University School of Medicine, 34450 Istanbul, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4913-6860","authenticated-orcid":false,"given":"Ahmet","family":"Peker","sequence":"additional","affiliation":[{"name":"Department of Radiology, Ko\u00e7 University School of Medicine, 34450 Istanbul, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0661-7867","authenticated-orcid":false,"given":"Yunus Emre","family":"Senturk","sequence":"additional","affiliation":[{"name":"Department of Radiology, Ko\u00e7 University School of Medicine, 34450 Istanbul, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8202-0931","authenticated-orcid":false,"given":"Rana","family":"Terlemez","sequence":"additional","affiliation":[{"name":"Department of Physical Medicine and Rehabilitation, Cerrahpa\u015fa Faculty of Medicine, Istanbul University, 34098 Istanbul, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-6359-4139","authenticated-orcid":false,"given":"Burak Ugur","family":"Cetin","sequence":"additional","affiliation":[{"name":"Department of Physical Medicine and Rehabilitation, Cerrahpa\u015fa Faculty of Medicine, Istanbul University, 34098 Istanbul, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2103-3293","authenticated-orcid":false,"given":"Ali Emre","family":"Oge","sequence":"additional","affiliation":[{"name":"Department of Neurology, Ko\u00e7 University School of Medicine, 34450 Istanbul, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3165-7358","authenticated-orcid":false,"given":"Aysegul","family":"Ketenci","sequence":"additional","affiliation":[{"name":"Department of Physical Medicine and Rehabilitation, Ko\u00e7 University School of Medicine, 34450 Istanbul, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,8,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"70","DOI":"10.1186\/1743-422X-4-70","article-title":"Epidemics to eradication: The modern history of poliomyelitis","volume":"4","year":"2007","journal-title":"Virol.
