Biomechanical Description of Technique:

The experimental technique consisted of precise measurements of several knee angles known to be relevant to PFPS symptoms and to acute ACL injuries. Those measurements were ascertained through the use of skin markers distributed on the lower extremities on subjects with no known histories of knee pathology or symptomatic complaints. After measuring VV and IRER angles in the neutral barefoot position, the researchers made similar measurements of those angles in several ski boot positions, including standing, canted, and rotated positions within the adjustable limitations of the ski boots. They also conducted measurements of simulated loading positions natural to skiing, achieved through the use of an angled platform duplicating the ski slope angle and a weighted pulley system designed to transmit downward forces between the skier and the sloped platform in the same perpendicular angle experienced during actual skiing.
