چکیده

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 study was designed to investigate the effect of these parameters on the ssr results. we measured the height and limb length of 65 normal individuals with different heights (divided into 3 groups of height ≤150 cm, 150-170 cm, and ≥170 cm). the participants had neither peripheral nor central neuropathy. they also had none of the exclusion criteria. then, they underwent ssr testing of both palms and soles. the correlation between the height and limb length in relation to ssr parameters (latency and amplitude) was analyzed statistically by pearson’s correlation. no significant correlation was detected between the height and limb length and the ssr amplitude. however, the results showed significant correlation between ssr latency recorded from all four sites (both palms and soles) and the height of participants. furthermore, there was a significant correlation between ssr latency recorded from any limb and the length of that limb. regarding the significant effect of the height and limb length on the ssr latency, both the height and limb length should be considered when interpreting the results of ssr.

Sympathetic Skin Response in patients with major depressive disorders

Introduction: Major depressive disorder (MDD) is one of the most prevalent diseases of psychiatry. There is evidence that suggests the autonomic nervous system plays a role in depression. Sympathetic Skin Response (SSR) is used to evaluate the autonomic system. Nerve Conduction Study (NCS) evaluates peripheral thick myelinated fibers. In SSR we evaluate thin unmyelinated fibers. The purpose of ...

sympathetic skin response and vasomotor symptoms in postmenopausal osteoporotic women

background: osteoporosis is a common disease characterized by reduction in bone mass, due to depletion of calcium and bone protein. a pivotal role of the sympathetic nervous system in bone remodeling has been considered. on the other hand, elevated central sympathetic activation in postmenopausal women is involved in the creation of vasomotor symptoms. also, sympathetic skin response (ssr) has ...

Suppressed sympathetic skin response in brain infarction.

BACKGROUND AND PURPOSE Autonomic failure is known to manifest commonly in stroke, but very little attention has been given to various features of sympathetic dysfunction such as sudomotor dysregulation in cerebrovascular diseases. In the present study, our purpose was to assess quantitatively sympathetic reflex activity in brain infarction by measuring the sympathetic skin response. METHODS W...
