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

Study Overview
=================
Brief Summary
-----------------
This is a crossover study that will investigate the immediate effects of a proximal therapeutic approach (SERF strap) and a distal one (foot orthoses) on knee pain intensity, global change, symptoms, ease of performance and confidence after each task and lower limb kinematics (hip adduction and internal hip rotation peak, rearfoor eversion peak) during functional taks (level-ground walking and stepping manoeuvres) in people with patellofemoral ostheoartritis

Detailed Description
-----------------
It will be enroled in this study 30 participants with patellofemoral ostheoartritis. The participants will be assessed during level walking at a self-selected speed and the stepping manoeuvre test under the three conditions that will be randomized: i) the control condition; ii) intervention proximal condition; and iii) intervention distal condition. The control condition refers to the condition in which no interventions will be administered. In both the intervention proximal condition and intervention distal condition, the respective therapeutic approach will be administered. For each functional task, three valid attempts will be collected. The primary outcome of this study is knee pain intensity and the secondary outcomes are both self-reported measures and kinematic variables measures. The self-reported measures are global change, symptoms, ease of performance and confidence, while the kinematic variables measures are hip adduction and internal hip rotation peak and rearfoor eversion peak
