BACKGROUND Many polio patients develop problems such as cold intolerance in the affected limbs, which seems to be due to sympathetic nervous system dysfunction. This study aimed to investigate whether there is a sympathetic system dysfunction in old-polio patients by means of the systematic skin response test. METHOD Forty old-polio patients and 20 healthy subjects were included in the study....

it is more than a decade since scientists are making use of sympathetic skin response (ssr) as a clinical and research method to evaluate sympathetic nervous system. a major portion of the efferent pathway of this response is composed of non-myelinated nerves. thus, the latency of the response may be significantly different in normal individuals with different height and limb lengths. this stud...

1. To investigate the nature of sympathetic dysfunction in the pathogenesis of reflex sympathetic dystrophy, the microcirculatory vasoconstrictive responses to dependency were investigated in the skin of the hand of 76 reflex sympathetic dystrophy patients with unilateral disease by means of laser Doppler flowmetry (in perfusion units) and capillary microscopy. The patients were divided into th...

The objective of this study was to evoke sympathetic skin responses (SSRs) in healthy subjects using laser stimulation and to compare these responses with those induced by conventional electrical stimuli. Twenty healthy subjects were investigated. SSRs were obtained using electrical and laser stimuli delivered to the wrist controlateral to the recording site. The sympathetic sudomotor conductio...

BACKGROUND Many physiological or pharmacological evaluations of autonomic function have been performed in patients with various types of cerebellar degeneration (CD). Few studies have been done, however, using neurographic recordings in patients with CD, especially of sudomotor or vasoconstrictor nerves. OBJECTIVE To confirm the clinical importance of sympathetic reflex latencies on the skin ...

This study evaluated relationships between irritable bowel syndrome (IBS) pain, sympathetic dysregulation, and thermal pain sensitivity. Eight female patients with diarrhea-predominant IBS and ten healthy female controls were tested for sensitivity to thermal stimulation of the left palm. A new method of response-dependent thermal stimulation was used to maintain pain intensity at a predetermin...

Rectal sensation is used as an investigative tool in the diagnosis of anorectal pathology. However, the data obtained are subjective depending on the patient's perception of the sensation. We investigated the hypothesis that sympathetic skin response (SSR) can be used as a tool for objective assessment of the rectal sensation. The SSR was recorded in 24 healthy volunteers (age 37.2 years, 14 me...
