The Orthostatic Blood Pressure (BP) Test is a simple yet essential clinical tool used to evaluate how the body regulates blood pressure during positional changes, typically from lying to standing. This test is especially valuable for identifying orthostatic hypotension and autonomic dysfunction, including conditions like Postural Orthostatic Tachycardia Syndrome (POTS), which are commonly associated with dizziness, lightheadedness, fatigue, and balance issues.

How the Test Works:
The test involves taking a patient’s blood pressure and heart rate after lying down for several minutes, then again immediately upon standing, and at intervals over the next 2 to 3 minutes. A significant drop in blood pressure or an abnormal increase in heart rate may indicate impaired autonomic regulation, which can be a key factor in concussion recovery, vestibular disorders, or persistent dizziness.

Clinical Applications:

• Concussion & Post-Concussion Syndrome

• Vestibular Disorders & Dizziness

• Suspected POTS or Autonomic Dysfunction

• Unexplained Falls or Lightheadedness

The Orthostatic BP Test is quick, low-cost, and non-invasive, making it ideal for use in physical therapy clinics, neurology offices, sports medicine, and primary care settings. Interpreting the results can help guide treatment strategies, such as hydration protocols, activity modifications, and referrals to appropriate specialists.

This test can be paired with symptom monitoring tools like the Visual Analog Scale (VAS) or Rate of Perceived Exertion (RPE) to provide a clearer picture of a patient's physiologic response to postural changes. It plays a critical role in understanding the broader picture of a patient’s health status, especially in cases involving complex neurological or vestibular symptoms.
