Quantitative autonomic nervous system testing is now possible noninvasively. This includes sudomotor, cardiovagal, and adrenergic function tests, crucial for accurate autonomic disorder diagnosis.

Area of Science:

  • Neuroscience
  • Clinical Physiology

Background:

  • The autonomic nervous system (ANS) regulates involuntary bodily functions.
  • Advancements enable quantitative, noninvasive, and reproducible ANS studies in clinical settings.

Purpose of the Study:

  • To describe the current methodologies for quantitative autonomic function testing.
  • To highlight the importance of patient preparation and technologist training.

Main Methods:

  • Quantitative sudomotor axon reflex test (QSART) for sympathetic nerve fibers.
  • Cardiovagal tests for parasympathetic cardiac nerves.
  • Adrenergic tests for baroreflex blood pressure regulation.

Main Results:

  • Established protocols allow for precise assessment of ANS components.
