Overview
Brief Summary
Inverted orthosis is a type of rigid foot orthosis that was designed to aid in controlling high degrees of foot pronation. It is essential to administer patients foot orthoses with different inverted angles, with higher angles prescribed when greater reduction of foot pronation is indicated. However, there is shortage of clinical knowledge regarding the inverted angle in terms of biomechanical changes. The aim of this study is to investigate the effect of different inverted angles of foot orthoses on the walking kinematics in females with flexible flatfeet.

Outcomes
Primary Outcomes
Lower limb kinematics
Time Frame: Through study completion, an average of 1 year.
Lower limb kinematics will be processed and calculated using a motion capture system (SMART-DX, BTS Bioengineering, Milan, Italy). The following kinematic variables will be obtained for each subject : (i) maximum hip extension angle, (ii) maximum hip adduction angle, (iii) maximum hip external rotation angle, (iv) maximum knee flexion angle during loading response, (v) maximum knee extension angle during midstance, (vi) maximum knee flexion angle at toe off, (vii) minimum knee abduction angle, (viii) maximum knee abduction angle, (ix) maximum knee external rotation angle, (x) maximum knee internal rotation angle, (xi) maximum ankle plantarflexion angle during loading response, (xii) maximum ankle dorsiflexion angle during midstance, (xiii) maximum ankle plantarflexion angle at toe off, (xiv) maximum ankle external rotation angle, (xv) maximum ankle internal rotation angle.
