Sudomotor Testing

Sudomotor testing evaluates sweat-gland activity and small-fiber nerve function. Abnormal sudomotor responses may be associated with autonomic dysfunction, diabetic neuropathy, or other peripheral nerve conditions.

Patients Who May Benefit

  • Patients with diabetes or prediabetes
  • Patients with burning, tingling, or numbness
  • Patients with suspected peripheral neuropathy
  • Patients with abnormal sweating
  • Patients with symptoms of autonomic dysfunction
  • Patients at risk for diabetic nerve complications

What Patients Can Expect

The patient places the hands and feet on the testing plates while the system records sudomotor responses. The test is noninvasive and is performed inside the physician’s clinic. The physician reviews and interprets the results.
