The Physio PS™ ANS Test is a non-invasive, data-driven diagnostic solution that empowers healthcare providers to assess the balance and function of the autonomic nervous system, specifically the parasympathetic and sympathetic branches. By uncovering hidden autonomic dysfunction, this test helps explain complex, persistent symptoms like fatigue, brain fog, chronic pain, dizziness, syncope, anxiety, digestive issues, and poor recovery, to name just a few.
