Proximal and Distal Therapeutic Approach in Pain and Lower Limb Kinematic in People With Patellofemoral Osteoarthritis

A global rating of change change (GRC) questionnaire

The GRC questionnaire is a 15 point self-report scale with criteria ranging from a 'very great deal worse' to a 'very great deal better.' The GRC is a valid and useful method for assessing the overall change in the quality of life of a person.

Time frame: The GRC will be assessed immediately after the third valid attempt of the level-walking task in the Intervention Proximal Condition
