Background Stair climbing demands, as compared to walking level, a greater range of motion in the lower extremity accompanied by about six times more load on knee joint [1]. Consequently, pain while climbing stairs is the first complaint in patients with knee osteoarthritis (OA) [2]. The use of lateral wedge insoles aims to decrease medial knee compartment loading by reducing the peak external knee adduction moment (EKAM) during walking [4]. The purpose of this study is to assess the biomechanical effects of wearing lateral wedge insoles on EKAM during stair climbing in elders with and without knee OA.
