The aim of this investigation was to determine whether gait is affected in a symptomatic, chronic mTBI group and to assess the relationship between gait performance and symptom severity on the Neurobehavioral Symptom Inventory (NSI). Gait was assessed under single- and dual-task conditions using five inertial sensors in 57 control subjects and 65 persons with chronic mTBI (1.0 year from mTBI). The single- and dual-task gait domains of Pace, Rhythm, Variability, and Turning were calculated from individual gait characteristics. Dual-task cost (DTC) was calculated for each domain. The mTBI group walked (domain z-score mean difference, single-task\u2009=\u20090.70; dual-task\u2009=\u20090.71) and turned (z-score mean difference, single-task\u2009=\u20090.69; dual-task\u2009=\u20090.70) slower (\n                    <jats:italic toggle=\"yes\">p<\/jats:italic>\n                    \u2009&lt;\u20090.001) under both gait conditions, with less rhythm under dual-task gait (z-score difference\u2009=\u20090.21;\n                    <jats:italic toggle=\"yes\">p<\/jats:italic>\n                    \u2009=\u20090.001). DTC was not different between groups. Higher NSI somatic subscore was related to higher single- and dual-task gait variability as well as slower dual-task pace and turning (\n                    <jats:italic toggle=\"yes\">p<\/jats:italic>\n                    \u2009&lt;\u20090.01). Persons with chronic mTBI and persistent symptoms exhibited altered gait, particularly under dual-task, and worse gait performance related to greater symptom severity. Future gait research in chronic mTBI should assess the possible underlying physiological mechanisms for persistent symptoms and gait deficits.\n                  <\/jats:p>","DOI":"10.1089\/neu.2020.6986","type":"journal-article","created":{"date-parts":[[2020,6,4]],"date-time":"2020-06-04T05:37:10Z","timestamp":1591249030000},"page":"218-224","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":21,"title":["Gait Performance in People with Symptomatic, Chronic Mild Traumatic Brain Injury"],"prefix":"10.1177","volume":"38","author":[{"given":"Douglas N.","family":"Martini","sequence":"first","affiliation":[{"name":"Department of Neurology, Oregon Health &amp;
