| Abstract | Abstract: In this study, to investigate the effect of external pressure on skin blood flow (SBF) of lower limb, external pressure was exerted on ankles and calves respectively by using sphygmomanometer. Alternating loading protocol was used: 5mins without pressure and 5mins under pressure of 40mmHg. The change of SBF was observed, wavelet analysis on the SBF signal was also performed. The results showed that SBF increased with pressure no matter it was loaded on ankle or calf. Wavelet analysis results showed that the peak spectrum amplitude in the frequency band of intrinsic myogenic activity increased (p<0.01) while its corresponding frequency decreased significantly (p<0.01) due to pressure loading. The mechanism of SBF’s response to external pressure was also discussed. |
