![]() However, the Balance Error Scoring System (BESS), the most common clinical balance assessment for a suspected mTBI, only subjectively measures postural control in a variety of static conditions (Riemann and Guskiewicz, 2000). Standing balance problems are well documented in collegiate athletes after mild traumatic brain injury (mTBI) (Guskiewicz, 2011 Broglio et al., 2014). The primary outcomes will be the measures of reactive postural responses and the time from first team activity to lower extremity injury.ĭiscussion: Results from this study will further our understanding of changes in balance control, across all domains, after mTBI and identify the extent to which postural responses can be used to assess injury risk in collegiate athletes. Acute lower extremity musculoskeletal injuries for each participant will be prospectively tracked for 1 year from the date of first team activity. In phase 2, student-athletes will undergo a baseline assessment of postural responses. The primary outcome will be measures of reactive postural response derived from wearable sensors during the Push and Release (P&R) test. The participants will be assessed at multiple time points along the return-to-play progress of the athlete with mTBI. Phase 1 will evaluate student-athletes who have sustained mTBI and teammate-matched controls who meet all the inclusion criteria. Methods: This two-phase study will take place at the University of Utah in coordination with the University of Utah Athletics Department. The purpose of this study is to (1) characterize reactive postural responses to recover balance in athletes with recent mTBI compared to healthy control subjects, (2) determine the extent to which reactive postural responses remain impaired in athletes with recent mTBI who have been cleared to return to play, and (3) determine the relationship between reactive postural responses and acute lower extremity musculoskeletal injuries in a general sample of healthy collegiate athletes. ![]() Our central hypothesis is that the high rate of musculoskeletal injuries after mTBI is in part due to impaired reactive balance control necessary for balance recovery. ![]() While impairments in some domains of balance control have been linked to musculoskeletal injuries, reactive balance control has received little attention in the mTBI literature, despite the inherent demand of balance recovery in athletics. However, a concrete mechanistic connection between post-mTBI deficits and musculoskeletal injuries has yet to be established. These deficits are speculated to contribute to the increased rate of musculoskeletal injuries after mTBI. Background: Deficits in neuromuscular control are widely reported after mild traumatic brain injury (mTBI).
