Balance Error Scoring System (BESS) primary purpose in concussion assessment?

• A. It measures respiratory rate during exercise
• B. It assesses static and dynamic balance in concussion assessment
• C. It analyzes cognitive function
• D. It evaluates hearing acuity

Answer: (B)

The main idea is evaluating a person’s balance after a concussion. BESS is designed to measure static and dynamic balance by having the athlete hold several stances on both firm ground and a foam surface, while counting visual cues of imbalance or moving out of position. The number of balance errors gives a score that reflects postural stability, which often becomes impaired after a concussion and helps clinicians monitor recovery and guide return-to-play decisions. This focus on balance is what makes it different from tests of respiratory rate (a cardiopulmonary measure), cognitive function (neurocognitive testing like memory and processing speed), or hearing acuity (audiology). So, its primary purpose is to assess static and dynamic balance in concussion assessment.
