Which measures are used to assess autonomic/exertional impairments in concussion evaluation?

• A. Heart rate and blood pressure in sitting, supine, and standing
• B. Only resting heart rate
• C. Blood pressure in standing position only
• D. No vital signs are required in this assessment

Answer: (A)

The key idea is that autonomic and exertional impairment after a concussion shows up in how the cardiovascular system responds to posture changes and activity, not just at rest. Checking heart rate and blood pressure in sitting, lying down, and standing lets you see how well autonomic control handles position shifts and light exertion. In many concussed patients, resting vitals can be normal, but the way HR and BP adjust when upright or during activity is abnormal, revealing orthostatic intolerance or exertional intolerance. So measuring both heart rate and blood pressure across multiple positions gives the most informative picture of autonomic/exertional status. Resting heart rate alone misses dynamic changes, standing blood pressure alone misses changes in other positions, and skipping vitals entirely would miss these critical responses.
