简要总结
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.
详细描述
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.

结局指标
主要结局
level of pain
时间窗: baseline
visual analogue scale 100-mm horizontal line anchored by word descriptors at each end by no the left and worst imaginable pain on the right
functional status
时间窗: baseline
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.
Dynamic knee valgus 2d frontal plane projection angle
时间窗: baseline
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.
次要结局
- isometric muscle power of hip abductor and external rotation(baseline)
