Abstract
It has been reported that patients with rheumatoid arthritis or asthma have skin conductance over the acupoints that is lower than that of their healthy counterparts; this has been regarded as indirect evidence of the existence of acupoints and the energy-based model of diseases. In order to investigate the potential application of acupoint-skin conductance measurement that may reflect pathology of ischemic stroke, the present study recruited 34 stroke survivors with hemiparesis, whose skin conductance of a hand acupoint and an adjacent non-acupoint and the finger temperature in both affected and unaffected hands were simultaneously measured; the data revealed that the skin conductance and finger temperature were statistically higher in the unaffected hand than that of the affected, and the skin conductance of the acupoint and the non-acupoint were comparable in the affected and unaffected hands respectively. We attribute the observed drop in the skin conductance to the diminished peripheral blood flow of the affected hand that is signified by relatively lower finger temperature. As such, it should be advisable when studying skin conductance over acupoints, monitoring the adjacent non-acupoint skin and local vascular circulation is essential.
