This study aimed to establish the inter- and intra-session reliability of the peak force for neck flexors, extensors, and side flexors using the VALD ForceFrame and DynaMo and the force\u2013time characteristics in the quadruped position (ForceFrame). Twenty-seven recreationally active males performed three repetitions of isometric neck flexion, extension, and side flexion over two sessions in random order using the VALD ForceFrame and DynaMo. Both devices demonstrated acceptable reliability, with the Forceframe ICC &gt; 0.8 and CV% &lt; 13.8% and the DynaMo ICC &gt; 0.76 and CV% &lt; 13.8%. No systematic or proportional differences were found using the Passing\u2013Bablock procedure, and Bland\u2013Altman analysis confirmed agreement across measures. Reliability was shown for right-side (ICC &gt; 0.76) and left-side (ICC &gt; 0.79) flexion and flexion (ICC &gt; 0.75) across 50, 100, 150, and 200 ms. Statistical parametric mapping indicated no differences in ForceFrame-generated isometric force\u2013time curves between sessions, though the CV was highest in the force development phase. The findings suggest that both tools can reliably assess neck strength, supporting their use in sports and clinical settings. However, assessment methods are not interchangeable, emphasising the need for standardised neck strength assessment approaches.<\/jats:p>","DOI":"10.3390\/s24155015","type":"journal-article","created":{"date-parts":[[2024,8,2]],"date-time":"2024-08-02T16:14:58Z","timestamp":1722615298000},"page":"5015","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Between-Session Reliability of Field-Based Assessments of Isometric Neck Strength"],"prefix":"10.3390","volume":"24","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2085-8277","authenticated-orcid":false,"given":"Samuel W.","family":"Oxford","sequence":"first","affiliation":[{"name":"Centre for Physical Activity Sport and Exercise Science, Coventry University, Priory Street, Coventry CV15FB, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1909-329X","authenticated-orcid":false,"given":"Neil D.","family":"Clarke","sequence":"additional","affiliation":[{"name":"College of Life Sciences, Faculty of Health, Education and Life Sciences, Birmingham City University, Edgbaston, Birmingham B153TN, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8904-2693","authenticated-orcid":false,"given":"Jason","family":"Tallis","sequence":"additional","affiliation":[{"name":"Centre for Physical Activity Sport and Exercise Science, Coventry University, Priory Street, Coventry CV15FB, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,8,2]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"695","DOI":"10.1136\/bjsports-2023-106898","article-title":"Consensus Statement on Concussion in Sport: The 6th International Conference on Concussion in Sport\u2013Amsterdam, October 2022","volume":"57","author":"Patricios","year":"2023","journal-title":"Br.
