The main objective of this study was to assess the validity of inertial measurements of the cervical spine range of motion (CROM) when compared to that of the optoelectronic system in a group of healthy individuals. A further aim of this study was to determine the optimal placement of the inertial sensor in terms of reliability of the measure, comparing measurements obtained from the same device placed at the second cervical vertebra (C2), the forehead (F) and the external occipital protuberance (EOP). Twenty healthy subjects were recruited and asked to perform flexion\u2013extension, lateral bending, and axial rotation movements of the head. Outcome measurements of interest were CROM and mean angular velocities for each cervical movement. Results showed that inertial measurements have good reliability (0.75 &lt; ICC &lt; 0.9). Excellent reliability (ICC &gt; 0.9) was found in both flexion and right lateral bending angles. All parameters extracted with EOP placement showed ICC &gt; 0.62, while ICC &lt; 0.5 was found in lateral bending mean angular velocities both for F and C2 placements. Therefore, the optimal sensor\u2019s positioning emerged to be EOP. These results suggest that inertial technology could be useful and reliable for the evaluation of the CROM.<\/jats:p>","DOI":"10.3390\/s23136013","type":"journal-article","created":{"date-parts":[[2023,6,29]],"date-time":"2023-06-29T01:43:13Z","timestamp":1688002993000},"page":"6013","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":17,"title":["Cervical Range of Motion Assessment through Inertial Technology: A Validity and Reliability Study"],"prefix":"10.3390","volume":"23","author":[{"given":"Martina","family":"Palmieri","sequence":"first","affiliation":[{"name":"Department of Electronics, Information and Bioengineering, Politecnico di Milano, Piazza Leonardo da Vinci 32, 20133 Milan, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4297-2433","authenticated-orcid":false,"given":"Lucia","family":"Donno","sequence":"additional","affiliation":[{"name":"Department of Electronics, Information and Bioengineering, Politecnico di Milano, Piazza Leonardo da Vinci 32, 20133 Milan, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6299-7254","authenticated-orcid":false,"given":"Veronica","family":"Cimolin","sequence":"additional","affiliation":[{"name":"Department of Electronics, Information and Bioengineering, Politecnico di Milano, Piazza Leonardo da Vinci 32, 20133 Milan, Italy"},{"name":"Istituto Auxologico Italiano, IRCCS, San Giuseppe Hospital, 28824 Piancavallo, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2772-4837","authenticated-orcid":false,"given":"Manuela","family":"Galli","sequence":"additional","affiliation":[{"name":"Department of Electronics, Information and Bioengineering, Politecnico di Milano, Piazza Leonardo da Vinci 32, 20133 Milan, Italy"}]}],"member":"1968","published-online":{"date-parts":[[2023,6,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"141","DOI":"10.3171\/2013.4.SPINE12838","article-title":"Cervical Spine Alignment, Sagittal Deformity, and Clinical Implications: A Review","volume":"19","author":"Scheer","year":"2013","journal-title":"J.
