Altering Lower Extremity Motion Patterns

Lower extremity musculoskeletal injuries have become a public health concern for active individuals when considering the complications that often present later in life after injury (eg, degenerative joint disease). 10 A recent surge of lower extremity injury prevention programs, 14,22 specifically aimed at ACL injury prevention, have provided some promising results in reducing knee injury among young female athletes after a jump-landing instructional program. Investigators have generally attempted to influence different intrinsic factors (eg, balance, flexibility, and strength) to potentially reduce the incidence of lower extremity injury. An important aspect of any training program is the influence that instructional technique can provide in " educating " athletes to land properly and possibly reduce acute and chronic lower extremity injuries. Numerous investigators have evaluated the effects of information feedback on performance and learning of Background: Anterior cruciate ligament injury prevention programs have used videotapes of jump-landing technique as a key instructional component to improve landing performance.
