| Popis: | Objectives: Sympathetic skin response (SSR) is a technique for assessment of the damage of peripheral neuropathies and the disorders of the sympathetic system. This study aimed to evaluate SSR among patients with Raynaud phenomenon (RP). Methods: Between January 1, 2015 and December 30, 2018, about 20 patients with RP and 20 healthy subjects as the control group were recruited from patients referring to the Outpatient Clinics of Shiraz medical University. All the participants were clinically examined, and the SSR was performed using a standard protocol. SSR is abnormal when the latency is prolonged and/or the amplitude reduced. Results: Raynaud's group consisted of 19 women (95 %) and 1 male (5%). 3 patients (15 %) with primary Raynaud's phenomenon (PRP) and 17 patients (85%) with secondary Raynaud's phenomenon (SRP). The control group consisted of 16 women (80%) and 4 males (20%). The mean age of the Raynaud's group and control subjects was 43.1±9 and 36.7±8.6 years, respectively. The SSR to the electrical stimulus was absent in 3 patients (PRP patients). The total median nerve mean latencies in the upper limb were 1.9±0.57 and 1.19±0.52 seconds for the Raynaud's group and control groups, respectively (p |
