Patellofemoral Pain Syndrome Clinical Prediction Rule Clinical Trial
Official title:
Development of Clinical Prediction Rule for Classifying Females With Patellofemoral Pain Syndrome Who Respond to Proximal Control Exercises
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 patient̀•̀•s response to proximal control exercises.

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. |

| Primary | functional status | Kujala questionnaire is a 13-items knee specific self-report questionnaire. It documents response to six activities thought to be associated specifically with anterior knee pain syndrome (walking, running, jumping, climbing stairs, squatting, and sitting for prolonged periods with knees bent), as well as symptoms such as limp, inability to bear weight through the affected limb, swelling, abnormal patellar movement, muscle atrophy and limitation of knee flexion. This questionnaire was used to ssess the individual's functional status and PFPS experienced during specific functional tasks. | baseline | |
| Primary | Dynamic knee valgus 2d frontal plane projection angle | 2D frontal plane projection angle (FPPA) analysis to measure dynamic knee valgus. for 2D FPPA analysis, the centers of each of hip, knee and ankle joints will be determined using a standard tape measure, markers will be placed at the midpoint of the ankle malleoli for the center of the ankle joint, midpoint of the femoral condyles to approximate the center of the knee joint, and on the proximal thigh at the midpoint of the line from the anterior superior iliac spine to the knee joint center. | baseline | |
| Secondary | isometric muscle power of hip abductor and external rotation | Hand held dynamometer will be used to asses isomteric hip abductor and isometric hip external rotator power | baseline |
