Influence of variable stiffness shoes on secondary gait mechanics in knee osteoarthritis patients

Variable Stiffness Shoes (VSS) have been developed to reduce external knee adduction moment (KAM) in patients with osteoarthritis (OA). This study’s findings suggest transverse and frontal plane gait adaptations in VSS that occur at the knee and hip need to be considered to understand the potential impact of VSS on structural or symptomatic OA progression.
