N/A patellofemoral pain syndrom. Intervention 1: Patients in the intervention group perform the quadriceps exercise, three times a week during 4 weeks. exercise protocol include: weeks 1-2: wall squat(0-45 of knee flextion)/15 repetition quadriceps isometric/4 sets of 25 repetitions straight leg raises/3 sets of 10 repetition weeks 3-4: wall squat(0-60 of knee flextion)/15 repetition quadriceps isometric/4 sets of 25 repetition straight leg rise/3 sets of 10 repetition terminal knee extension/3 sets of 10 repetition an exercise log provides for monitoring all subjects .If the load level elicited pain, it will decrease. Intervention 2: The control group do not participate in any intervention.

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. 12 years 40 years Both M22.2 Patellofemoral disorders Rehabilitation N/A Patients in the intervention group perform the quadriceps exercise, three times a week during 4 weeks. exercise protocol include: weeks 1-2: wall squat(0-45 of knee flextion)/15 repetition quadriceps isometric/4 sets of 25 repetitions straight leg raises/3 sets of 10 repetition weeks 3-4: wall squat(0-60 of knee flextion)/15 repetition quadriceps isometric/4 sets of 25 repetition straight leg rise/3 sets of 10 repetition terminal knee extension/3 sets of 10 repetition an exercise log provides for monitoring all subjects .If the load level elicited pain, it will decrease The control group do not participate in any intervention.
