Abstract
The aim of the current investigation was to examine the effects of orthoses with a 5°
medial and lateral wedge on knee and ankle joint kinetics in female runners.
Twelve healthy female runners ran at 3.5 m/s over a force platform in three
conditions (medial, lateral and no-orthotic). Lower extremity kinematics were
measured using an 8-camera motion capture system, which allowed knee and ankle loading to be explored using a musculoskeletal modelling approach. The peak
Achilles tendon force was significantly larger in the no-orthotic condition
(5.34 BW) compared to the lateral orthosis (5.03 BW). The peak patellofemoral
stress was significantly larger in the medial orthosis (7.32 MPa) compared to
the no-orthotic (7.02 MPa) condition. Finally, the peak knee adduction moment
was significantly larger in the medial condition (1.14 Nm/kg) compared to the
lateral (0.99 Nm/kg) orthosis. The findings from the current investigation
indicate that lateral orthoses may be effective in attenuating risk of medial
tibiofemoral osteoarthritis and Achilles tendinopathy, but medial wedge
orthoses may increase the risk of patellofemoral pain in female runners.
