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

Conditions

• Patellofemoral Osteoarthritis

Interventions

Type	Name	Description
DEVICE	Elastic hip strap	The SERF Strap consist of a thin, elastic material that is secured to the proximal aspect of the leg, wraps in a spiral fashion around the thigh, and is anchored around the pelvis. The line of action of the SERF Strap pulls the hip into abdcution and external rotation.
DEVICE	Insole	Foot orthoses with semi-rigid arch support and medial elevation at the forefoot and at the rearfoot by 7° each that is made from a block of ethyl vinyl acetate with a thermo-moldable polymer (shore hardness of 45 A) and is manufactured through an automated computer numeric control machine (CNC routers).
