“…Moreover, SSR are evoked by impulses that originate in a different area to which the response is produced. For example, electrical pulses over the sternal skin can be used to elicit SSR in the palms [19], which highlight the complexity of the internal neuronal network involving polysynaptic relays and connections between different vertical levels along the neuraxis and in both sides of the human body [11]. It is, therefore, not surprising that measurement of a SSR depends on the site and the type of stimulus used to initiate the reflex.…”

“…The patients were questioned regarding the following autonomic symptoms: excessive sweating, feeling cold, and color change of the feet. Again, 1 point was awarded for the presence of each symptom, and summed to provide the sympathetic system score (SSS) 9,13-15. The maximum scores for TSS, TFS, and SSS were 6, 14, and 3, respectively.…”

Background and PurposeElectrodiagnostic studies can be used to confirm the diagnosis of lumbosacral radiculopathies, but more sensitive diagnostic methods are often needed to measure the ensuing motor neuronal loss and sympathetic failure.MethodsTwenty-six patients with lumbar radiculopathy and 30 controls were investigated using nerve conduction studies, motor unit number estimation (MUNE), testing of the sympathetic skin response (SSR), quantitative electromyography (QEMG), and magnetic resonance myelography (MRM).ResultsUsing QEMG as the gold standard, the sensitivity and specificity of MUNE for the abductor hallucis longus muscle were 71.4% and 70%, respectively. While they were 75% and 68.8%, respectively, when used MRM as gold standard. The sensitivity and specificity of MUNE for the extensor digitorum brevis muscle were 100% and 84.1%, respectively, when the peroneal motor amplitude as the gold standard. The SSR latency was slightly longer in the patients than in the controls.ConclusionsMUNE is a simple and sensitive test for evaluating autonomic function and for diagnosing lumbosacral radiculopathy in patients. MUNE could be used routinely as a guide for the rehabilitation of patients with radiculopathies. SSR measurements may reveal subtle sympathetic abnormalities in patients with lumbosacral radiculopathy.

“…The range of the parameters reported in the literature in CTS patients and in healthy controls includes amplitudes from 1 to 7 mV and latencies from 1.4 to 3 ms (Caccia et al, 1993;Kanzato et al, 2000;Kiylioglu et al, 2005;Mondelli et al, 2000;Reddeppa et al, 2000;Sener et al, 2000). In our study, the range of amplitudes in affected hands was 0.1-9.6 mV, in unaffected 0.1-9.8 mV, the area in affected hands 0.2-10.5 mVms, and in unaffected hands 0.4-10.6 mVms.…”

“…There have been several sympathetic skin response studies in CTS patients and their results are not consistent: reduced or normal sympathetic activity was reported in the majority (Caccia et al, 1993;Kanzato et al, 2000;Mondelli et al, 2000;Reddeppa et al, 2000;Sener et al, 2000). Vasomotor dysfunction in digital arteries was found in CTS patients in two studies, which employed the Doppler technique (Galea et al, 2006;Wilder-Smith et al, 2003).…”

“…Moreover, it is not clear whether compression results in an increase or inhibition of sympathetic activity, which translates into different clinical effects: Raynaud phenomenon, blanching and excessive sweating in the former, and dryness as well as warmness of the hand in the latter. The spectrum of these features in CTS patients as reported in the literature is wide and includes both situations (Caccia et al, 1993;Mondelli et al, 2000;Sener et al, 2000;Verghese et al, 2000).…”

The objective of this study was to assess sympathetic activity within the hand in patients with unilateral carpal tunnel syndrome. In 53 patients, 42 female (79%) and 11 male (21%), having a mean age of 56 years, with clinically and electrophysiologically confirmed unilateral CTS, the sympathetic skin response (SSR) and capillaroscopy examination of the nail folds was obtained for the affected and unaffected hand. Mean values of the SSR parameters did not differ statistically significantly between affected and unaffected hands. Qualitative analysis of the SSR graphs revealed no response in one patient (2%), reduced SSR in seven (13%) and normal SSR in 45 patients (85%). Capillaroscopy showed that the mean diameters of afferent and efferent capillary vessels were not statistically significantly different in the affected and unaffected hand. The results obtained in our study indicate a slight but statistically insignificant effect of the compression of the median nerve on the activity of the sympathetic nervous system in the distribution of this nerve.
