Recovery of static stability following a concussion

Balance assessment is an integral component of concussion evaluation and management. Although the modified balance error scoring system (mBESS) is the conventional clinical tool, objective metrics derived from wearable inertial sensors during the mBESS may increase sensitivity in detecting subtle balance deficits post-concussion. The aim of this study was to identify which stance condition and postural sway metrics obtained from an inertial sensor placed on the lumbar spine during the mBESS best discriminate athletes with acute concussion. Fifty-two college athletes in the acute phase of concussion and seventy-six controls participated in this study. Inertial sensor-based measures objectively detected group differences in the acutely concussed group of athletes while the clinical mBESS did not (p<0.001 and p = 0.06, respectively). Mediolateral postural sway during the simplest condition of the mBESS (double stance) best classified those with acute concussion. Inertial sensors provided a sensitive and objective measure of balance in acute concussion. These results may be developed into practical guidelines to improve and simplify postural sway analysis post-concussion.

“…High school and collegiate football players appear to undergo similar levels of head acceleration during impact, 5 but due to the immaturity of the musculoskeletal system, younger athletes may possess a diminished ability to control the head and reduce head acceleration after impact, potentially leading to increased stress of brain tissue. 5 Previous concussion-related research has revealed postinjury deficits to brain function through neuropsychological testing, 8,21 attentional testing, 11,13 static balance testing, 4,27 and dynamic balance testing. 14,26 Dual-task balance assessments in particular have been reported to provide a sensitive detection of persistent neurological deficits and may help to identify compromised processes that may require more healing after concussion.…”
