Abstract

PURPOSE: Assessments of oculomotor, balance, and exercise function detect different responses to mild traumatic brain injury (mTBI) in sport-related mTBI. These assessments are understudied in the adult community mTBI population. We evaluated level 1 trauma center patients with non-sports related mTBI on oculomotor functioning (near point of convergence [NPC] and accommodation [NPA]), balance (Balance Error Scoring System [BESS]), and exercise tolerance (Buffalo Concussion Treadmill Test [BCTT]).

METHODS: A prospective, cohort study of adults with mTBI (N = 36) were assessed at 1 week and (N = 26) 1 month post-mTBI using NPC, NPA, BESS, BCTT, and the Rivermead Post Concussion Symptoms Questionnaire [RPQ]. Prevalence of test impairment and association between performance and mTBI-related symptom burden (RPQ scores) were characterized.

RESULTS: Participants demonstrated varying levels of impairment (e.g., 33.3% oculomotor, 44.1% balance, and 55.6% exercise impairment at 1 week). Participants displayed diverse impairment profiles across assessments. We observed medium-to-large correlations between poorer NPC and BCTT performance and greater mTBI symptom burden.

CONCLUSIONS: Clinical examinations of oculomotor function, balance, and exercise adopted from sport-related concussion assessments detect impairment in adult community members with mTBI. While findings warrant larger-scale replication, they imply that incorporating these simple, structured exams into the assessment of mTBI may facilitate more personalized management strategies.
