The objectives of this study were to investigate postural control responses and spatiotemporal parameters of gait during level and uphill unloaded (UL), back-loaded (BL), and front-loaded (FL) walking. Postural control was assessed in 30 asymptomatic individuals by simultaneously recording (i) EMG activity of neck, thoracic and lumbar erector spinae, and rectus abdominis, (ii) projected 95% ellipse area as well as the anteroposterior and mediolateral trunk displacement, and (iii) spatiotemporal gait parameters (stride\/step length and cadence). Measurements were performed during level (0%) and uphill (5, 10, and 15%) walking at a speed of 5 km h\u22121 without and with a suspended front pack or a backpack weighing 15% of each participant\u2019s body weight. The results of our study showed that postural control, as indicated by increased erector spinae EMG activity and changes in spatiotemporal parameters of gait that manifested with decreased stride\/step length and increased cadence, is compromised particularly during level and uphill FL walking as opposed to BL or UL walking, potentially increasing the risk of musculoskeletal and fall-related injuries.<\/jats:p>","DOI":"10.3390\/s23020609","type":"journal-article","created":{"date-parts":[[2023,1,5]],"date-time":"2023-01-05T04:51:31Z","timestamp":1672894291000},"page":"609","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Effects of Load Carriage on Postural Control and Spatiotemporal Gait Parameters during Level and Uphill Walking"],"prefix":"10.3390","volume":"23","author":[{"given":"Asimina","family":"Mexi","sequence":"first","affiliation":[{"name":"Sports Physical Therapy Laboratory, Department of Physical Education and Sports Science, School of Physical Education and Sports Science, National and Kapodistrian University of Athens, 17237 Athens, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8148-5630","authenticated-orcid":false,"given":"Ioannis","family":"Kafetzakis","sequence":"additional","affiliation":[{"name":"Sports Physical Therapy Laboratory, Department of Physical Education and Sports Science, School of Physical Education and Sports Science, National and Kapodistrian University of Athens, 17237 Athens, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maria","family":"Korontzi","sequence":"additional","affiliation":[{"name":"Sports Physical Therapy Laboratory, Department of Physical Education and Sports Science, School of Physical Education and Sports Science, National and Kapodistrian University of Athens, 17237 Athens, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1848-5627","authenticated-orcid":false,"given":"Dimitris","family":"Karagiannakis","sequence":"additional","affiliation":[{"name":"Sports Physical Therapy Laboratory, Department of Physical Education and Sports Science, School of Physical Education and Sports Science, National and Kapodistrian University of Athens, 17237 Athens, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Perikles","family":"Kalatzis","sequence":"additional","affiliation":[{"name":"Section of Informatics 1st Vocational Lyceum of Vari, Directorate of Secondary Education of East Attica, Hellenic Ministry of Education and Religious Affairs, 16672 Athens, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8358-7438","authenticated-orcid":false,"given":"Dimitris","family":"Mandalidis","sequence":"additional","affiliation":[{"name":"Sports Physical Therapy Laboratory, Department of Physical Education and Sports Science, School of Physical Education and Sports Science, National and Kapodistrian University of Athens, 17237 Athens, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,1,5]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"402","DOI":"10.1191\/0269215500cr342oa","article-title":"What Is Balance?","volume":"14","author":"Pollock","year":"2000","journal-title":"Clin.
