However, the extent to which neurological dysfunction persists after blast exposure is unknown. This longitudinal study examined the potential short- and long-term effects of repeated subconcussive blast exposure on neuromotor performance from heavy weapons training in military personnel. A total of 214 participants were assessed; 137 were exposed to repeated subconcussive blasts and 77 were not exposed to blasts (controls). Participants completed a short stepping-in-place task while an Android smartphone app placed on their thigh recorded movement kinematics. We showed acute suppression of neuromotor variability 6 h after subconcussive blast exposure, followed by a rebound to levels not different from baseline at the 72 h, 2-week, and 3-month post-tests. It is postulated that this suppression of neuromotor variability results from a reduction in the functional degrees of freedom from the subconcussive neurological insult. It is important to note that this change in behavior is short-lived, with a return to pre-blast exposure movement kinematics within 72 h.<\/jats:p>","DOI":"10.3390\/s24217064","type":"journal-article","created":{"date-parts":[[2024,11,4]],"date-time":"2024-11-04T10:57:20Z","timestamp":1730717840000},"page":"7064","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["An Objective Assessment of Neuromotor Control Using a Smartphone App After Repeated Subconcussive Blast Exposure"],"prefix":"10.3390","volume":"24","author":[{"given":"Charlend K.","family":"Howard","sequence":"first","affiliation":[{"name":"Ellmer College of Health Sciences, Old Dominion University, Norfolk, VA 23529, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8885-506X","authenticated-orcid":false,"given":"Masahiro","family":"Yamada","sequence":"additional","affiliation":[{"name":"Department of Kinesiology, Whittier College, Whittier, CA 90602, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-2501-4749","authenticated-orcid":false,"given":"Marcia","family":"Dovel","sequence":"additional","affiliation":[{"name":"Military Traumatic Brain Injury Initiative (MTBI2), Uniformed Services University, Bethesda, MD 20814, USA"},{"name":"Henry M.
