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

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.

Primary Outcome Measures

Name	Time	Method
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 Outcome Measures

Name	Time	Method
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.
