简要总结
Patellofemoral pain syndrome (PFPS) is a multifactorial pathology characterized by diffuse retropatellar and peripatellar pain in the knee joint, exacerbated by overloading activities on the patellofemoral joint. However, this disease showed high degree of patients not responsive to therapeutic strategies. This condition occurred because several factors is related to disease such as: (1) proximal factors (involving trunk and hip), (2) local factors (surrounding and or within the patellofemoral joint) and (3) distal factors (involving ankle and foot). Thus, the identification of clinical subgroups based in anatomic changes (proximal, local and distal factors) is a recent strategy that could help in the therapeutic strategies focused on the etiology of the disease, improve responsiveness to treatment, clinical and functional benefits.

结局指标
主要结局
Muscular strength tests of hip and knee muscles.
时间窗: 1 day
Isometric torque of knee extensor muscles, hip abductor, extension and medial rotation muscles through hand-held dynamometer tests will be performed to create clinical subgroups after cluster analysis for a focused intervention in the second step.
Muscle thickness measures
时间窗: 1 day
Muscle thickness (in millimeters) of vastus lateralis, vastus medialis and rectus femoris muscle. Muscle thickness of gluteus medius, maximus and peroneus muscle through ultrasound equipment. Tests Test will be performed to create clinical subgroups after cluster analysis for a focused intervention in the second step.
Muscle activation of knee, hip and foot muscles
时间窗: 1 day
Muscle activation measures of quadriceps, gluteus maximus, gluteus medius and peroneus muscles during unilateral squat through surface electromyography. Tests will be performed to create clinical subgroups after cluster analysis for a focused intervention in the second step.
Kinematics during unilateral squat
时间窗: 1 day
Pelvis, hip, knee and ankle angular displacement during unilateral squat through kinematics analysis. Tests will be performed to create clinical subgroups after cluster analysis for a focused intervention in the second step.
Fascicle length measures
