Proximal and Distal Therapeutic Approach in Pain and Lower Limb Kinematic in People With Patellofemoral Osteoarthritis
Study Details
Study Description
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;
- 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
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| No Intervention: Control condition In this condition there will not be any application of therapeutic approach. |
|
| Experimental: Intervention proximal condition The proximal therapeutic approach will be the SERF strap (S.E.R.F. strap; DonJoy Orthopedics, Inc., vista, CA). |
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.

| Experimental: Intervention distal condition The distal therapeutic approach will be a pair of foot orthoses with semi-rigid arch support and medial elevation at the forefoot and at the rearfoot by 7° each (Propulsão Produtos Biomecânicos, Minas Gerais, Brazil). |
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).
