Autonomic Nervous System Testing used to diagnose any autonomic disorder
The autonomic nervous system controls many of the automatic functions in your body such as heart rate and blood pressure and sends nerves to various organs so that they may function properly. Dysfunction of the autonomic nervous system can produce a myriad of symptoms including lightheadedness/dizziness, burning pain, difficulty with digestion and even problems with sweating. The tests, which are performed by a technician, takes about an hour and there is no pain associated with the testing.
The tests include:
1) Autonomic Nervous System Monitoring (ANSAR)
The ANX 3.0 tests are two independent clinical tests (or studies) designed to determine the ability of both branches of the autonomic nervous system (ANS) to respond to and relax from a challenge. The two branches that make up the ANS are the sympathetic and parasympathetic (SNS and PSNS, respectively). The challenges are:
1) deep breathing to challenge the PSNS,
2) valsalva to challenge the SNS, and
3) standing from a seated position to challenge both systems.
2) Quantitative Sweat Measurement (QSWEAT)
A key component in determining the severity and pattern of autonomic disorders is the study of a patient’s sudomotor response. The Q-Sweat, provided by WR Medical Electronics, brings sudomotor testing to your clinic. The Q-Sweat examines the integrity of the postganglionic sympathetic sudomotor axon, assisting in the diagnosis of small fiber neuropathies.
The QSWEAT has been used by multiple specialties to diagnose the following disorders
