Patellofemoral pain.
Conditions
Interventions
Intervention group: 30 runners with patellofemoral pain that will receive training in three different racing techniques
these will be divided into 3 subgroups (10 runners train the technical one - race with landing initiated in the forefoot, 10 runners will train the technical 2 - Race with the highest number of steps,

Eligibility
Age
18 Years to 35 Years
Inclusion criteria
Inclusion criteria: Rearfoot strikers, familiar with treadmillrunning and run a minimum of 20 km/wk at least 3 months prior to study enrollment All must have previous anterior or retropatellar pain in at least three of these activities: up/down stairs, squatting, running, kneeling, jumping and after seated for long periods; insidious onset of symptoms unrelated to traumatic incident and persistent for at least three months during the running activity; presence of pain after patellar compression and usual pain in the last week of at least 3 cm on the visual analog scale of 10 cm.
Exclusion criteria
Exclusion criteria: Signs or symptoms of: meniscal or intra-articular pathology; previous knee joint ligament injuries; ligamentous laxity; sign of patellar apprehension; Osgood-Schlatter or Sinding-Larsen-Johansson syndrome; lumbar spine, hip or ankle pain; prior patellar dislocation; evidence of knee joint effusion; lower limb surgery; cardiovascular or neurological diseases.
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Kinematics: lower limb and trunk joint angles assessment. Electromyography: evaluation of the electrical activity of the lower limb muscles through a electromyography and surface electrodes. Plantar Pressure Distribution Detection system: landing pattern evaluation during the running. The data will be obtained before, immediately after the modification of the technique and after 2 weeks of training in the technique. It is expected that the change in the immediate running technique improve the biomechanics of the lower limb during the running, contributing to a reduction in the activity of injury. | — |
Secondary
| Measure | Time frame |
|---|---|
| Visual Analogue Scale: Graduate in 10 cm, validated and specific scale for pain assessment and comfort. Lower Extremity Functional questionnaires and Kujala: validated and translated, specific evaluation questionnaires limitation or loss of function. The data will be obtained before, immediately after the modification of the technique and after 2 weeks of training in the technique. | — |
