The value of concomitant testing of cutaneous silent period with sympathetic skin response and heart rate variability in Type-2 diabetes patients: An electrophysiological study.

Objective: To explore the association among cutaneous silent period, sympathetic skin response and heart rate variability in diabetes patients.

Methods: The case-control study was conducted at the Department of Physiology, College of Medicine, Al- Mustansiriyah University, Baghdad, Iraq, from November 1, 2020, to May 20, 2021, and comprised 24 healthy controls in Group I and 49 patients of type 2 diabetes in Group II who were recruited from the neuroelectrophysiological unit of Al-Imamain Al-Kadhmean Teaching Hospital, Baghdad, Iraq. Both groups were subjected to cutaneous silent period, sympathetic skin response and heart rate variability testing.
