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.
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.
