Overview
Brief Summary
The purpose of this is to test lateral foot orthoses with different amount of wedging to find a model that predicts the optimal lateral inclination of foot orthosis based on biomechanical or feelings measures. This study was a cross-sectional study with patients serving as their own control. The investigators recruited 24 knee osteoarthritis. Knee radiography and clinical angles measures was carried out before making orthoses, then motion analysis with an optoelectronic system was performed with each pair of foot orthoses. During motion analysis, five gait trials were carried out in each condition.

Outcomes
Primary Outcomes
Knee adduction moment
Time Frame: At time of device receipt
Measure of the knee adduction moment is a non invasive technic to identify change in medial knee loading, major problem in medial knee osteoarthritis.
Knee pain
Time Frame: At time of device receipt
A 20-cm visual analog scale (0-100) is used to assess pain.
Secondary Outcomes
- Foot orthoses comfort(At time of device receipt)
