Neurol."],"abstract":"<jats:sec><jats:title>Introduction<\/jats:title><jats:p>Among patients with traumatic brain injury (TBI), postural instability often persists chronically with negative consequences such as higher fall risk. One explanation may be reduced executive function (EF) required to effectively process, interpret and combine, sensory information. In other populations, a decline in higher cognitive functions are associated with a decline in walking and balance skills. Considering the link between EF decline and reduction in functional capacity, we investigated whether specific tests of executive function could predict balance function in a cohort of individuals with a history of chronic mild TBI (mTBI) and compared to individuals with a negative history of mTBI.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Secondary analysis was performed on the local LIMBIC-CENC cohort (<jats:italic>N<\/jats:italic> = 338, 259 mTBI, mean 45 \u00b1 STD 10 age). Static balance was assessed with the sensory organization test (SOT). Hierarchical regression was used for each EF test outcome using the following blocks: (1) the number of TBIs sustained, age, and sex; (2) the separate Trail making test (TMT); (3) anti-saccade eye tracking items (error, latency, and accuracy); (4) Oddball distractor stimulus P300 and N200 at PZ and FZ response; and (5) Oddball target stimulus P300 and N200 at PZ and FZ response.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The full model with all predictors accounted for between 15.2% and 21.5% of the variability in the balance measures. The number of TBI's) showed a negative association with the SOT2 score (<jats:italic>p<\/jats:italic> = 0.002). Additionally, longer times to complete TMT part B were shown to be related to a worse SOT1 score (<jats:italic>p<\/jats:italic> = 0.038). EEG distractors had the most influence on the SOT3 score (<jats:italic>p<\/jats:italic> = 0.019). Lastly, the SOT-composite and SOT5 scores were shown to be associated with longer inhibition latencies and errors (anti-saccade latency and error, <jats:italic>p<\/jats:italic> = 0.026 and <jats:italic>p<\/jats:italic> = 0.043 respectively).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>These findings show that integration and re-weighting of sensory input when vision is occluded or corrupted is most related to EF. This indicates that combat-exposed Veterans and Service Members have greater problems when they need to differentiate between cues when vision is not a reliable input. In sum, these findings suggest that EF could be important for interpreting sensory information to identify balance challenges in chronic mTBI.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fneur.2022.906661","type":"journal-article","created":{"date-parts":[[2023,1,11]],"date-time":"2023-01-11T06:22:49Z","timestamp":1673418169000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":3,"title":["Executive function and relation to static balance metrics in chronic mild TBI: A LIMBIC-CENC secondary analysis"],"prefix":"10.3389","volume":"13","author":[{"given":"Susanne M.","family":"van der Veen","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Robert A.","family":"Perera","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Laura","family":"Manning-Franke","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Amma A.","family":"Agyemang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Karen","family":"Skop","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Scott R.","family":"Sponheim","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elisabeth A.","family":"Wilde","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alexander","family":"Stamenkovic","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"James S.","family":"Thomas","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"William C.","family":"Walker","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2023,1,11]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"668","DOI":"10.1177\/1545968309332879","article-title":"Rhythm perturbations in acoustically paced treadmill walking after stroke","volume":"23","author":"Roerdink","year":"2009","journal-title":"Neurorehabil Neural Repair."},{"key":"B2","doi-asserted-by":"publisher","first-page":"261","DOI":"10.1016\/j.gaitpost.2020.08.114","article-title":"Foot-placement accuracy during planned and reactive target stepping during walking in stroke survivors and healthy adults","volume":"81","author":"van der Veen","year":"2020","journal-title":"Gait Posture."},{"key":"B3","doi-asserted-by":"publisher","first-page":"3467","DOI":"10.1007\/s00221-015-4407-5","article-title":"Effects of aging and dual tasking on step adjustments to perturbations in visually cued walking","volume":"233","author":"Mazaheri","year":"2015","journal-title":"Exp Brain Res."},{"key":"B4","doi-asserted-by":"publisher","first-page":"617","DOI":"10.1016\/S0140-6736(97)24009-2","article-title":"Stops walking when talking\u201d as a predictor of falls in elderly people","volume":"349","author":"Lundin-Olsson","year":"1997","journal-title":"Lancet."},{"key":"B5","doi-asserted-by":"publisher","first-page":"46","DOI":"10.1177\/0891988720901779","article-title":"Spatial-temporal parameters of gait associated with alzheimer disease: a longitudinal analysis","volume":"34","author":"Oh","year":"2021","journal-title":"J Geriatr Psychiatry Neurol."},{"key":"B6","doi-asserted-by":"publisher","first-page":"315","DOI":"10.1227\/00006123-198403000-00009","article-title":"Sequelae associated with head injuries in patients who were not hospitalized: a follow-up survey","volume":"14","author":"Coonley-Hoganson","year":"1984","journal-title":"Neurosurgery."},{"key":"B7","doi-asserted-by":"publisher","first-page":"173","DOI":"10.1080\/026990599121692","article-title":"Epidemiology and predictors of post-concussive syndrome after minor head injury in an emergency population","volume":"13","author":"Bazarian","year":"1999","journal-title":"Brain Injury."},{"key":"B8","doi-asserted-by":"publisher","first-page":"5","DOI":"10.1111\/j.1600-0404.1992.tb03987.x","article-title":"Minor head injury: impact on general health after 1 year.
