The aim of the current study was to evaluate changes in stiffness (shear modulus), cross-sectional area (CSA), and trace length (TRACE) of the ulnar nerve in patients with cubital tunnel syndrome (CuTS), with shear wave elastography (SWE). A total of 31 patients with CuTS were included. CSA, shear modulus, and TRACE examinations were performed in the SWE mode in four positions of the elbow: full extension, 45\u00b0 flexion, 90\u00b0 flexion, and maximum flexion. There were significant side-to-side differences in the ulnar nerve elasticity value at 45\u00b0, 90\u00b0, and maximal elbow flexion (all, p &lt; 0.001) but not at elbow extension (p = 0.36). There were significant side-to-side differences in the ulnar nerve CSA value at each elbow position (all, p &lt; 0.001). There were significant side-to-side differences in the ulnar nerve trace value at each elbow position (all, p &lt; 0.001). The symptomatic ulnar nerve in patients with CuTS exhibited greater stiffness (shear modulus), CSA, and TRACE values, compared with the asymptomatic side. US examinations (shear modulus, CSA, and TRACE evaluation) of the ulnar nerve can be helpful in supporting and supplementing the diagnosis in patients with CuTS.<\/jats:p>","DOI":"10.3390\/s22218354","type":"journal-article","created":{"date-parts":[[2022,11,2]],"date-time":"2022-11-02T06:49:02Z","timestamp":1667371742000},"page":"8354","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Changes in Ultrasound Measurements of the Ulnar Nerve at Different Elbow Joint Positions in Patients with Cubital Tunnel Syndrome"],"prefix":"10.3390","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7910-757X","authenticated-orcid":false,"given":"Tomasz","family":"Wolny","sequence":"first","affiliation":[{"name":"Musculoskeletal Elastography and Ultrasonography Laboratory, Institute of Physiotherapy and Health Sciences, The Jerzy Kukuczka Academy of Physical Education, Miko\u0142owska 72A, 40-065 Katowice, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3772-9690","authenticated-orcid":false,"given":"C\u00e9sar","family":"Fern\u00e1ndez-de-las-Pe\u00f1as","sequence":"additional","affiliation":[{"name":"Department of Physical Therapy, Occupational Therapy, Rehabilitation and Physical Medicine, Universidad Rey Juan Carlos, 28922 Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Arkadiusz","family":"Granek","sequence":"additional","affiliation":[{"name":"Hospital of the Ministry of Interior and Administration, 25-316 Kielce, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8542-8123","authenticated-orcid":false,"given":"Pawe\u0142","family":"Linek","sequence":"additional","affiliation":[{"name":"Musculoskeletal Elastography and Ultrasonography Laboratory, Institute of Physiotherapy and Health Sciences, The Jerzy Kukuczka Academy of Physical Education, Miko\u0142owska 72A, 40-065 Katowice, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,10,31]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"672","DOI":"10.5435\/00124635-200711000-00006","article-title":"Entrapment neuropathy of the ulnar nerve","volume":"15","author":"Elhassan","year":"2007","journal-title":"J.
