The autonomic nervous system regulates important body functions such as blood pressure, heart rate, respiration rate and perspiration. An Autonomic Function Test (AFT) helps to measure these body functions.
The results help in evaluation of neurological conditions with autonomic involvement (e.g. Parkinson's disease, nerve damage (peripheral neuropathy)) and symptoms (e.g. fainting spells, dizziness, balancing problems).
