Sudomotor QSART Test

Quantitative Sudomotor Axon Reflex Test (QSART)

Introduction

Quantitative Sudomotor Axon Reflex Test (QSART) is a test to evaluate the integrity of the postganglionic sudomotor system along the axon reflex to define the distribution of sweat loss. This is accomplished by the release of bio-impedance electrical stimulation the skin which activates receptors on the eccrine sweat gland. The sweat response is recorded from four sites (forearm and 3 lower extremity sites) and assessed for deficits.

The QSART is a test that measures the autonomic nerves that control sweating. The test is useful in assessing autonomic nervous system disorders, peripheral neuropathies and some types of pain disorders. The test requires a mild electrical stimulation on the skin, which allows to stimulate sweat glands. The QSART measures the volume of sweat produced by this stimulation.

QSART is used to diagnose:

  • Painful, small fiber neuropathy when nerve conduction test results are normal
  • Disturbances of the autonomic nervous system, which controls the sweat glands, heart, digestive system, other organs, and blood pressure
  • Complex pain disorders
  • Diabetic neuropathies
  • Enzyme disorders
  • RSD (Reflex Sympathetic Dystrophy, Complex Regional Pain Syndrome)
  • Dysautonomia
  • Pharmaceutical agents
  • Cosmetics/Consumer goods testing
  • Dermatological studies
  • Multiple System Atrophy (Shy-Drager syndrome)
