Study on Effect of External Pressure on Skin Blood Flow at Lower Limb Using Wavelet Analysis

摘要：

To understand circulation control mechanism of skin blood flow (SBF) responding to various stimulus, wavelet analysis was widely used. External pressure was one of the factors induced SBF response. In this study, SBF at ankle and calf under pressure of 20mmHg in sitting posture respectively were observed, then wavelet analysis on SBF signals was also carried out. The results showed that SBF increased when external pressure exerted no matter on ankle or calf. Moreover, the increment at ankle was bigger than that of calf. Wavelet analysis results showed that peak spectrum amplitude of intrinsic myogenic activity increased, while characteristic frequency decreased significantly (p<0.01) due to pressure loading. Its implicated that external pressure induced the change of myogenic activity and thus affected SBF.
