A Three-Dimensional Analysis Of Subtalar And Knee Joint Coupling During Running Over Obstacles, Tracy Allan Dierks

Student Work

Running has been associated with a number of lower extremity overuse injuries. Attention has been given to biomechanical factors, specifically, excessive pronation and excessive tibial rotation. It has been suggested that excessive tibial rotation is due to excessive foot pronation transferred through a coupling mechanism. The ankle and knee are mechanically linked via the tibia and excessive tibial internal rotation may delay tibial external rotation as the knee begins to extend. Increased impact forces have also been implicated as a cause of running injuries, although little is known about this possible relationship. Obstacle heights have been used previously to produce …
