To delve deeper into this topic, this study analyzed the functional and neuromuscular alterations at the head\u2010and\u2010neck region during high\u2010altitude trekking by combining thermal imaging, electromyography, and kinematics. Fifteen adults who took part in a Himalayan expedition were tested for cervical range of motion (RoM) at 1400\u2009m, at peak altitude staying (5000 meters), and once back at 1400\u2009m, during a trek lasting 14\u2009days. The 8 males were also tested for surface electromyography (sEMG) and infrared thermography. The maximum RoM of flexion\u2010extension along the sagittal plane increased in response to trekking. Surface electromyography revealed greater activation at the end of the trek in right side for rotation and the left side for bending. Thermography revealed a general reduction of skin temperature over the target muscles during side bending. This study highlights the feasibility and usefulness of multimodal analysis through inertial measurement unit\u2010registered kinematics, thermography, and electromyography in monitoring neck function in a demanding real\u2010world environment. The high\u2010altitude trek, with a backpack weighing less than 10% of one's body weight, triggers asymmetrical adaptations in the neck muscles, increasing measured RoM.<\/jats:p>","DOI":"10.14814\/phy2.71060","type":"journal-article","created":{"date-parts":[[2026,8,19]],"date-time":"2026-08-19T06:35:31Z","timestamp":1787121331000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["An exploratory, in\u2010field, multimodal assessment of cervical function in adults following to high\u2010altitude trekking with light backpack"],"prefix":"10.14814","volume":"14","author":[{"given":"David","family":"Perpetuini","sequence":"first","affiliation":[{"name":"BioEng Lab, Department of Engineering and Geology University G. d'Annunzio of Chieti\u2010Pescara  Pescara Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vittore","family":"Verratti","sequence":"additional","affiliation":[{"name":"Department of Science University \u201cG. d'Annunzio\u201d Chieti\u2010Pescara  Chieti Italy"},{"name":"Italian Society of Mountain Medicine  Padova Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1911-3606","authenticated-orcid":false,"given":"Danilo","family":"Bondi","sequence":"additional","affiliation":[{"name":"Department of Neuroscience, Imaging and Clinical Sciences University \u201cG. d'Annunzio\u201d Chieti\u2010Pescara  Chieti Italy"},{"name":"Department of Life, Health and Environmental Sciences University of L'aquila  L'Aquila Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Arcangelo","family":"Merla","sequence":"additional","affiliation":[{"name":"BioEng Lab, Department of Engineering and Geology University G. d'Annunzio of Chieti\u2010Pescara  Pescara Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Egidio","family":"Botta","sequence":"additional","affiliation":[{"name":"Department of Innovative Technologies in Medicine &amp; Dentistry University \u201cG.
