Brief summary: the aim of study is to investigate the effect of body mass index (BMI), age, duration of symptoms, pain severity and knee angle valgus on patient̕̕s response to proximal control exercises.

Detailed description: Patellofemoral pain syndrome (PFPS) is recognized as one of the most common lower-extremity disorders encountered by orthopaedic physical therapists. Females were 2.23 times more likely to develop PFPS than males. Various authors have suggested that hip weakness may be an impairment associated with PFPS, because poor hip control may lead to abnormal lower extremity or patellofemoral motions. Clinical prediction rules (CPRs) are tools designed to improve decision making in clinical practice by assisting practitioners in making a particular diagnosis, establishing a prognosis, or matching patients to optimal interventions.

Eligibility criteria: Inclusion Criteria:

* Age 18 to 35 years.
* Anterior or retropatellar knee pain of non-traumatic origin that was greater than six weeks duration and provoked by at least two predefined activities (prolonged sitting or kneeling, squatting, jogging or running, hopping, jumping, or stair walking).
* Pain on palpation of the patellar facets, or with step down from a 15 cm step, or double leg squat.

Exclusion Criteria:

1. Concomitant injury or pathology of other knee structures.
2. Previous knee surgery.
3. patellofemoral instability (history of sublaxation or dislocation; positive apprehension test).
4. knee joint effusion.
5. Osgood-Schlatter's.
6. hip or lumbar spine pain (local or referred).
7. physiotherapy within previous year; prior foot orthoses treatment or use of anti inflammatories or corticosteroids.
