Modulation of human muscle spindle discharge by arterial pulsations--functional effects and consequences. [PDF]

PLoS ONE, 2012
Arterial pulsations are known to modulate muscle spindle firing; however, the physiological significance of such synchronised modulation has not been investigated.

Intraocular Pressure Reduction Is Associated with Reduced Venous Pulsation Pressure

PLOS ONE, 2016
To explore whether alterations in intraocular pressure (IOP) affect vein pulsation properties using ophthalmodynamometric measures of vein pulsation pressure.Glaucoma patients had two retinal vein pulsation pressure (VPP) measurements from upper and lower hemiveins performed by ophthalmodynamometry at least 3 months apart.
