Patellofemoral pain syndrome
Conditions
Interventions
Randomized clinical trial, two arms, including 30 women with patellofemoral pain syndrome between 18 and 30 years old. The volunteers were randomized into two groups
experimental group (EG,n-15) and control group (CG,n-15). The randomization process was carried out by way of a random number table created in a computer resulting in both groups. The women allocated

Inclusion criteria
Inclusion criteria: Women agend between 18 and 30 years old, anterior or retropatellar knee pain during at least two of the folling activities: ascending/descending stairs, squating, running, jumping and prolonged sitting, insidious onset of the symptoms being unrelated to a traumatic incident and persistent for at least 8 weeks, presence of pain on palpation of the patellar facets, usual pain in the last week of at least 3cm in the Visual Analogue Scale (VAS) of 10cm.
Exclusion criteria
Exclusion criteria: Signs or symptoms of meniscal disorders, cruciate or collateral ligament involvement, tenderness over the patellar tendon, iliotibial band, or pes anserinus tendons, sign of patellar apprehension, Osgood-Schlatter or Sinding-Larsen-Johansson syndromes, hip or lumbar referred pain, history of patellar dislocation, evidence of knee joint effusion, previous surgery on the knee joint.
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Worst patellofemoral pain in the last week. Patellofemoral pain will be evaluated using a 10-cm visual analogue scale with 0 indicating no pain and 10 indicating extremely intense pain. We hypothesized that when compared to the control group, the experimental group would show greater improvement in pain at 2 and 5 month follow-up assessments. | — |
Secondary
| Measure | Time frame |
|---|---|
| Three-dimensional kinematics will be assessed during the single leg squat and the step-down task using the electromagnetic system Flock of Birds miniBird® (Ascension Technology Corporation, Burlington, VT, USA)and the Motion Monitor software(Innovative Sports Training, Inc. Chicago, IL, USA). The following variables will be studied: excursion of knee adduction/abduction, hip flexion/extension and adduction/abduction, pelvis anteversion/retroversion and ipsilateral/contralateral depression, trunk flexion/extension and lateral flexion. We hypothesized that when compared to the control group, the experimental group would show less movement excursion of ipsilateral trunk inclination, pelvis contralateral depression, hip adduction and knee abduction, as well as greater movement excursion of hip flexion during the single leg squat at 2 month follow-up assessment. ;The eccentric knee extensor, knee flexor, hip abductor, hip adductor, hip medial rotator and hip lateral rotator isokinetic peak torques will be studied using the isokinetic dynamometer (Biodex Multi-Joint System 2, Biodex Medical Inc., New York, USA). We hypothesized that when compared to the control group, the experimental group would show greater improvement in the eccentric hip abductor and lateral rotator torque as well as knee flexor torque at 2 month follow-up assessment. ;Funcional performance will be evaluated through the triple hop test. To measure the distance jumped in the test, a standard tape measure will be fixed to the ground, perpendicular to the starting line of the test. To carry out this test, the subjects will be instructed to execute 3 consecutive maximum jumps on the affected limb and maintain their balance on the last landing for at least 2 seconds before placing the contralateral limb on the ground. We hypothesized that when compared to the control group, the experimental group would show greater improvement in functional performance at 2 month follow-up assessment. ;Trunk muscles | — |
