Sympathetic Skin Response (SSR) is a non-invasive neurophysiological test used to assess the function of the autonomic nervous system, particularly the sympathetic nerves that control sweat gland activity. The test records the electrical response of the skin to various stimuli and helps identify abnormalities affecting autonomic nerve function.

When is SSR Recommended?

Your doctor may recommend an SSR test if you have symptoms suggestive of autonomic nervous system dysfunction.

• Excessive or reduced sweating
• Numbness or tingling in the hands and feet
• Suspected peripheral or autonomic neuropathy
• Dizziness or fainting related to autonomic dysfunction
• Assessment of nerve damage in diabetes and other neurological disorders

Conditions Diagnosed

SSR helps evaluate disorders affecting the autonomic nervous system.

• Autonomic Neuropathy
• Diabetic Neuropathy
• Peripheral Neuropathy
• Complex Regional Pain Syndrome (CRPS)
• Other Disorders Affecting the Sympathetic Nervous System

Benefits of SSR

• Evaluates autonomic nerve function accurately
• Helps detect early autonomic nerve damage
• Supports diagnosis of neuropathies and neurological disorders
• Assists in treatment planning and monitoring
• Safe, painless, and non-invasive diagnostic procedure
