“…Although there are other methods for measuring peripheral blood flow and vasoconstrictor reflexes, or evaluating peripheral autonomic function, the present method has given reliable and consistent results in the hands of the author, and other workers have also commented on its value in this respect (eg Greenfield et al, 1963). Nevertheless, the electrodermal or galvanic skin reflex-a change in skin potential that is evoked by a number of different stimuli-may be complementary to the technique used in this study, since the galvanic skin and peripheral vasoconstrictor reflexes appear to use independent postganglionic pathways and are behaviourally distinct (Prout, 1967;Furedy and Gagnon, 1969).…”

“…Patients were informed on the SSR method prior to examination. Patients were positioned supine and relaxed on a secured bed in a silent examination room kept at 22℃-24℃ or higher [ 5 , 6 , 7 , 8 , 9 , 10 ]. The skin temperature was maintained at 32℃-36℃ [ 11 , 12 , 13 , 14 , 15 , 16 , 17 ].…”

ObjectiveTo investigate the predictive value of the sympathetic skin response (SSR) in diagnosing complex regional pain syndrome (CRPS) by comparing three diagnostic modalities-SSR, three-phasic bone scans (TPBS), and thermography.MethodsThirteen patients with severe limb pain were recruited. Among them, 6 were diagnosed with CRPS according to the proposed revised CRPS clinical diagnostic criteria described by the International Association for the Study of Pain. SSR was measured in either the hands or feet bilaterally and was considered abnormal when the latency was prolonged. A positive TPBS finding was defined as diffuse increased tracer uptake on the delayed image. Thermographic findings were considered positive if a temperature asymmetry greater than 1.00℃ was detected between the extremities.ResultsFive of 6 CRPS patients showed prolonged latency on SSR (83% sensitivity). TPBS was positive in the 5 CRPS patients who underwent TPBS (100% sensitivity). Thermography was positive in 4 of 5 CRPS patients who underwent the procedure (80% sensitivity). The remaining 7 non-CRPS patients differed on examination. SSR latencies within normal limit were noted in 4 of 7 non-CRPS patients (57% specificity). Results were negative in 4 of 5 non-CRPS patients who underwent TPBS (80% specificity), and negative in 3 of 5 non-CRPS patients who underwent thermography (60% specificity).ConclusionSSR may be helpful in detecting CRPS.

“…The sympathetic innervation of sweat glands induces changes in skin resistance to an externally applied current (exosomatic method). The central (28) and the peripheral (9) pathways involved in the generation of EDA are independent of pathways producing vasoconstriction for thermoregulation. However, vasoconstriction is known to alter EDA (11).…”
