Stretch Exercise: To stretch Tensor fascia lata muscle,each participant starts with side lying position with the tested limb upmost. The lower limb (non-tested) is kept in hip and knee flexion to ensure stability. The tested limb is then taken into hip extension and adduction with knee extended. The exercise is held for 60 seconds and repeated 5 times with 10 seconds break intervals.
Study summary
Patellofemoral pain syndrome (PFPS) is one of the most typical causes of anterior knee pain in adolescents and young adults under the age of 50.It is believed that imbalanced action between quadriceps components, is the most contributing cause of PFPS.Investigating exercises that increase VMO muscle activation and enhance the ratio between VMO and VL have been a standardized target in literature.
