This cross-sectional comparative study included 23 patients between 40-80 years of age from the University of Kansas Medical Centre, and controls.
The participants underwent extensive testing, including the Functional Gait Assessment (FGA, to determine deficits with dynamic balance). Moreover, they completed a Post-Concussion Symptom Scale (PCSS) and DHI (Dizziness Handicap Inventory); both subjective patient-reported outcome measures.
The FGA test consists of several head positions and movements while walking, as well as walking with eyes closed, and backwards, to investigate overall tolerance for functional mobility. Oculomotor tests were also conducted for visual acuity and near point convergence.
