Fig. 1 Diagrammatic representation of experimental model: Laser Doppler probe, installed in polyethylene chamber, is applied to supramalleolar region underneath blood pressure cuff. Inflating blood pressure cuff also inflates polyethylene chamber via Y junction. Computer data logging system records laser Doppler parameters from laser Doppler flowmeter.

Fig. 2 Relationship between interface pressure sensing device and sphygmomanometer readings in 10 subjects. Pressure applied to cuff, indicated on sphygmomanometer, ranged from 10 to 100 mm Hg and was within 5 mm Hg of pressure reading indicated by interface pressure sensor.

Fig. 5 Effect of leg compression on LDF, BCV, and CMBC in patients with LDS. Medians of LDF, BCV, and CMBC are plotted in AU. p is Wilcoxon matched-pairs signed rank test, comparing values at 20 mm Hg compression to basal values at 0 mm Hg; ns, not significant. A, Horizontal position. B, Dependent position.
