Sympathetic skin response (SSR) testing measures sudomotor sympathetic nerve activity. Abnormal SSR can indicate neurological disorders like diabetic neuropathy and Parkinson's disease.

Area of Science:

  • Neuroscience
  • Autonomic Nervous System Physiology

Context:

  • The sympathetic skin response (SSR) is a physiological measurement reflecting sudomotor sympathetic efferent fiber activity.
  • SSR is typically recorded via surface electrodes on the extremities following electrical stimulation.
  • Variability in amplitude and latency, along with habituation, are inherent characteristics of SSR.

Purpose:

  • To evaluate the diagnostic utility of the sympathetic skin response (SSR) as an indicator of autonomic function.
  • To establish criteria for identifying abnormal SSR findings.
  • To correlate SSR abnormalities with specific neurological conditions.

Summary:

  • SSR is a slow wave generated by sudomotor sympathetic efferent fibers, often recorded from the hand or foot.
  • Significant variability and habituation necessitate careful interpretation; absence of response is considered abnormal.

  • SSR demonstrates strong correlation with other autonomic function tests and is frequently abnormal in diabetic neuropathy, cerebrovascular disease, and Parkinson's disease.

    • Impact:

    • SSR serves as a reliable and simple clinical tool for assessing sympathetic sudomotor outflow.
    • Abnormal SSR findings aid in the diagnosis and management of central and peripheral nervous system disorders.
    • This test contributes to understanding the pathophysiology of various neurological conditions affecting autonomic function.
