Inclusion criteria
Inclusion criteria: Inclusion criteria: peripatellar or retropatellar pain provoked by at least 2 of the following activities: prolonged sitting with flexed knees, stair climbing, squatting, running, kneeling, and jumping(including landing after a jump); exhibition of 2 or more of the following clinical criteria on assessment: pain on direct compression of the patella against the femoral condyles with the knee in full extension, tenderness on palpation of the posterior edge at the medial and/or lateral border of the patella, and pain on direct compression of the patella against the femur during isometric quadriceps contraction with the knee in slight flexion; age between 12 and 40 years old; the presence of patellofemoral pain for a minimum of 3 months. Exclusion criteria: history or evidence of other knee disorders like ligament injury, bursitis, meniscal injury, or osteoarthritis; lower limb surgery or trauma during last year; patellar instability; referred pain from the lumbar spine and ankle joint; existence of any abnormality in lower limb and spine; loss of flexibility of the soft tissue structures such as the quadriceps, hamstrings, triceps surae; the position and mobility of the subject's patella were then clinically assessed using the method described by McEwan et al. The subjects were also excluded if their patellae demonstrated lateral deviation greater than 5 mm; lateral patella tilt; hypo or hypermobility on medial glide of the patella.
