Motor Control Retraining vs Close Kinetic Chain Exercises for Pain, Function and Vastus Medialis Oblique Strength in Patients With Patellofemoral Pain Syndrome

Background: Patellofemoral pain syndrome, another name for anterior knee discomfort, isbrought on by a combination of abnormal patellar tracking, changed biomechanics, andmuscle imbalances that put more strain on the patellofemoral joint during activitiesincluding jogging, squatting, and stair climbing. In general practice, patellofemoralpain contributes to 11‐17% of all knee pain syndromes. Motor control retraining is arehabilitation treatment that focus on activation and timing of VMO, controlledfunctional movements, dynamic integration while close kinetic chain exercises is also arehabilitation treatment that focus on low and moderate load close kinetic chainexercises with advanced functional exercises that focuses on VMO activation.
