Effect of muscle compensation on knee instability during ACL-deficient gait

Article Abstract:

An investigation was undertaken to determine whether an isolated change in either quadriceps or hamstrings muscle force is sufficient to stabilize the ACL-deficient (ACLd) knee during gait. The model simulations showed that increased hamstrings force was sufficient to stabilize the ACLd knee during gait and reduced quadriceps force was insufficient to restore normal anterior tibial translation for portions of the gait cycle

Effects of walking poles on lower extremity gait mechanics

Article Abstract:

This article examines the beneficial effects of walking poles on lower extremity loading while walking on level surfaces. Results indicate that walking poles increased walking speed, stance time, and stride length while reducing compressive ground and joint reaction forces.

Statistical Data Included, Physiological aspects, Biomechanics, Gait, Staffs (Sticks, canes, etc.), Walking sticks (Canes)

Model prediction of anterior cruciate ligament force during drop-landings

Article Abstract:

The pattern of force transmitted to the anterior cruciate ligament (ACL) during soft-style drop-landings is discussed. The results indicated that the pattern of ACL force in drop-landing cannot be explained by the anterior pull of the quadriceps force alone.
