XIN, S. ... et al., 2008. Study on blood pulse photoplethysmography signal on toe under different body posture and lower limb height. Journal of University of Shanghai for Science and Technology = [Shanghai Ligong Daxue Xuebao], 30 (5), pp.173-180.
Under two body-postures (supine and 45° reclining) the blood pulse signal on toe was detected via non-invasive photoplethysmography technique while the lower limb was passively raised in different height. The regulations of blood pulse volume and lower limb height were found and their relation was described through curves in figures.
