However, the effects of EXOs on local dynamic stability (LDS), a measure of motor control, have not been established. Eleven active duty Army Soldiers (9 males, aged 22 [4]\u00a0y) completed a familiarization session, followed by 2 testing sessions where they did (EXO) or did not (NoEXO) wear a pneumatic powered, knee-actuated EXO. Inertial measurement units were attached bilaterally to the shank and posterior pelvis. Participants completed a 2-mile ruck march on a treadmill at a self-selected pace (1.34 [0.10]\u00a0m\/s), carrying a load equal to 30% of body weight and an additional 9.07\u00a0kg for the EXO during that session. LDS was calculated using gyroscope data for 100 strides at the 0.25- (Start) and 2-mile (End) marks of the march. For the right shank, LDS was found to be significantly lower for EXO versus NoEXO (mean difference\u2009=\u20090.28,\n                    <jats:italic>P<\/jats:italic>\n                    \u2009&lt;\u2009.01, partial\n                    <jats:italic>\u03b7<\/jats:italic>\n                    <jats:sup>2<\/jats:sup>\n                    \u2009=\u2009.75). A similar effect was found for the left shank, and while not significant, the effect size was large (\n                    <jats:italic>P<\/jats:italic>\n                    \u2009=\u2009.07, partial\n                    <jats:italic>\u03b7<\/jats:italic>\n                    <jats:sup>2<\/jats:sup>\n                    \u2009=\u2009.29). Finally, LDS was higher at the pelvis in the EXO versus NoEXO, and with a large effect size, although the results were not significant (\n                    <jats:italic>P<\/jats:italic>\n                    \u2009=\u2009.07, partial\n                    <jats:italic>\u03b7<\/jats:italic>\n                    <jats:sup>2<\/jats:sup>\n                    \u2009=\u2009.29). Our results suggest that lower-extremity EXOs reduce distal LDS, which may point to the need for habituation periods for new users of EXOs.\n                  <\/jats:p>","DOI":"10.1123\/jab.2025-0125","type":"journal-article","created":{"date-parts":[[2025,12,15]],"date-time":"2025-12-15T18:03:45Z","timestamp":1765821825000},"page":"77-84","source":"Crossref","is-referenced-by-count":0,"title":["Effects of a Pneumatic Knee-Actuated Exoskeleton on Gait Stability During Prolonged Walking With Load Carriage"],"prefix":"10.1123","volume":"42","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4945-7813","authenticated-orcid":true,"given":"Caleb D.","family":"Johnson","sequence":"first","affiliation":[{"name":"Military Performance Division, U.S. Army Research Institute of Environmental Medicine, Natick, MA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lucas C.","family":"Sarantos","sequence":"additional","affiliation":[{"name":"Military Performance Division, U.S. Army Research Institute of Environmental Medicine, Natick, MA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dominik","family":"Fohrmann","sequence":"additional","affiliation":[{"name":"Institute of Interdisciplinary Exercise Science and Sports Medicine, Faculty of Medicine, MSH Medical School Hamburg, Hamburg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Karsten","family":"Hollander","sequence":"additional","affiliation":[{"name":"Institute of Interdisciplinary Exercise Science and Sports Medicine, Faculty of Medicine, MSH Medical School Hamburg, Hamburg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"David J.","family":"Zeppetelli","sequence":"additional","affiliation":[{"name":"Military Performance Division, U.S. Army Research Institute of Environmental Medicine, Natick, MA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cole A.","family":"Dempsey","sequence":"additional","affiliation":[{"name":"Military Performance Division, U.S. Army Research Institute of Environmental Medicine, Natick, MA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takashi","family":"Nagai","sequence":"additional","affiliation":[{"name":"Military Performance Division, U.S. Army Research Institute of Environmental Medicine, Natick, MA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"100","reference":[{"issue":"1","key":"r1","series-title":"Ergonomics","doi-asserted-by":"publisher","first-page":"61","DOI":"10.1080\/00140139.2022.2059106","article-title":"A systematic literature review of evidence for the use of assistive exoskeletons in defence and security use cases","volume":"66","author":"Farris DJ","year":"2023","unstructured":"Farris DJ, Harris DJ, Rice HM, et\u00a0al.
