Objective Correlation between current perception threshold and sympathetic skin response was investigated in patients with diabetic or alcoholic polyneuropathy.
Methods Current perception threshold was measured using Neurometer CPT/C, and the sympathetic skin response was measured using Neuropack Σ.
Patients Fourteen patients with diabetic polyneuropathy and 10 patients with alcoholic polyneuropathy were studied.
Results There was a significant negative correlation between the current perception threshold to 5 Hz stimulation and the amplitude of sympathetic skin response.
Conclusion Since both current perception threshold to 5 Hz stimulation and sympathetic skin response are related to C fibers, these two are considered to be impaired concurrently in diabetic and alcoholic polyneuropathies.
