Summary
The sympathetic skin response (SSR) can be a sensitive clinical test. Simultaneous palm and sole recordings enhance SSR test sensitivity for systemic pathway assessment.
Area of Science:
- Neuroscience
- Clinical Electrophysiology
Background:
- The sympathetic skin response (SSR) is a valuable indicator of autonomic nervous system function.
- Assessing SSR sensitivity is crucial for its reliable clinical application.
Purpose of the Study:
- To establish a method for optimizing the sympathetic skin response (SSR) as a sensitive clinical diagnostic tool.
- To investigate the characteristics of SSRs recorded simultaneously from palms and soles.
Main Methods:
- Utilized a non-invasive technique to simultaneously record SSRs using a 4-channel EMG machine.
- Recruited 30 healthy adults (10 women, 20 men; aged 19-46) for the study.
Main Results:
- Palmar SSR latencies were faster and amplitudes were higher compared to plantar SSRs.
- Observed differences suggest SSR is a long systemic response, not segmental.
Conclusions:
- Simultaneous recording of palmar and plantar SSRs enhances test sensitivity.
- Utilizing more than two EMG channels is recommended for lesion detection in the SSR pathway.
