This was a descriptive, observational, cross-sectional, feasibility study. Participants performed a full-range craniocervical flexion and the CCFT. During the CCFT, a pressure sensor and a wireless inertial sensor simultaneously registered data of pressure and ROM. A web application was developed using HTML and NodeJS technologies. Forty-five participants successfully finished the study protocol (20 males, 25 females; 32 (11.48) years). ANOVAs showed large effect significant interactions between pressure levels and the percentage of full craniocervical flexion ROM when considering the 6 pressure reference levels of the CCFT (p &lt; 0.001; \u03b72 = 0.697), 11 pressure levels separated by 1 mmHg (p &lt; 0.001; \u03b72 = 0.683), and 21 pressure levels separated by 0.5 mmHg (p &lt; 0.001; \u03b72 = 0.671). The novel time synchronizing system seems a feasible option to provide real-time monitoring of both pressure and ROM, which could serve as reference targets to further investigate the potential use of inertial sensor technology to assess or train deep cervical flexors.<\/jats:p>","DOI":"10.3390\/s23083911","type":"journal-article","created":{"date-parts":[[2023,4,12]],"date-time":"2023-04-12T03:49:17Z","timestamp":1681271357000},"page":"3911","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Potential Use of Wearable Inertial Sensors to Assess and Train Deep Cervical Flexors: A Feasibility Study with Real Time Synchronization of Kinematic and Pressure Data during the Craniocervical Flexion Test"],"prefix":"10.3390","volume":"23","author":[{"given":"Elena","family":"Bocos-Corredor","sequence":"first","affiliation":[{"name":"Departamento de Fisioterapia, Facultad de Medicina, CEU San Pablo University, 28668 Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9640-1324","authenticated-orcid":false,"given":"Tom\u00e1s","family":"P\u00e9rez-Fern\u00e1ndez","sequence":"additional","affiliation":[{"name":"Departamento de Fisioterapia, Facultad de Medicina, CEU San Pablo University, 28668 Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6962-1778","authenticated-orcid":false,"given":"Raquel","family":"Perez-Dominguez","sequence":"additional","affiliation":[{"name":"Departamento de Tecnolog\u00edas de la Informaci\u00f3n, Escuela Polit\u00e9cnica Superior, CEU San Pablo University, 28668 Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sonia","family":"Li\u00e9bana","sequence":"additional","affiliation":[{"name":"Departamento de Fisioterapia, Facultad de Medicina, CEU San Pablo University, 28668 Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7942-433X","authenticated-orcid":false,"given":"Susan","family":"Armijo-Olivo","sequence":"additional","affiliation":[{"name":"Faculty of Business and Social Sciences, University of Applied Sciences, 53604 Osnabr\u00fcck, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7176-6984","authenticated-orcid":false,"given":"Rafael","family":"Raya","sequence":"additional","affiliation":[{"name":"Departamento de Tecnolog\u00edas de la Informaci\u00f3n, Escuela Polit\u00e9cnica Superior, CEU San Pablo University, 28668 Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Aitor","family":"Martin-Pintado-Zugasti","sequence":"additional","affiliation":[{"name":"Departamento de Fisioterapia, Facultad de Medicina, CEU San Pablo University, 28668 Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,4,12]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"284","DOI":"10.1016\/j.mayocp.2014.09.008","article-title":"Epidemiology, Diagnosis, and Treatment of Neck Pain","volume":"90","author":"Cohen","year":"2015","journal-title":"Mayo Clin.
