VMO from Dave Parise CPT FPTA MES on Vimeo.
Anterior knee pain syndrome (AKPS) represents a significant problem for patients and sports medicine clinicians. Many predisposing factors have been associated with AKPS. Considerable attention has been given to quadriceps strengthening. Specifically the vastus medialis oblique (VMO) muscle is targeted for selective strengthening. Because of the VMO’s oblique attachment to the patella, researchers report that proper dynamic alignment of the patella is dependent on VMO control.
The vastus medialis oblique (VMO) is one of four quadriceps muscles which extend the knee joint and stabilize the knee in weight bearing. The knee is a modified hinge joint which means it is more complicated than a door hinge. Subtle but important accessory motion occurs with movement in many extremity joints. Accessory rotation in the knee (the femur rotates slightly medially relative to a stationary tibia) occurs during weight bearing, and decreases joint wear and improves patella-femoral joint function. The VMO is the quadriceps muscle responsible for accessory joint motion during the final few degrees of knee joint extension. Building and maintaining strength in the VMO, therefore, is an important component in your training.
