Quantifying the effects of external shear loads on arterial and venous blood flow: implications for pressure ulcer development.
INTRODUCTION Forces applied to the skin cause a decrease in regional blood flow. This decrease in blood flow can cause tissue necrosis and lead to the formation of deep, penetrating wounds calledExpand

Blood perfusion and transcutaneous oxygen level characterizations in human skin with changes in normal and shear loads--implications for pressure ulcer formation.
BACKGROUND Decubitus ulcers (pressure ulcers) are localized areas of tissue breakdown in the skin and the underlying regions. Decubitus ulcers affect approximately 3 million people in the USA everyExpand

An approach for hip joint center calculation for use in seated postures.
In seated postures, such as those in office or automotive seats, locating the hip joint center (HJC) using three markers on the pelvis has been difficult if not impossible. A two-target approach byExpand

Support force measures of midsized men in seated positions.
Two areas not well researched in the field of seating mechanics are the distribution of normal and shear forces, and how those forces change with seat position. The availability of these data wouldExpand

Differences in human cervical spine kinematics for active and passive motions of symptomatic and asymptomatic subject groups.
Most musculoskeletal disorders of the head and neck regions cannot be identified through imaging techniques; therefore clinician-conducted assessments (passive motions) are used to evaluate theExpand
