Effects of knee osteoarthritis severity on inter-joint coordination and gait variability as measured by hip-knee cyclograms

Abstract Inter-joint coordination and gait variability in knee osteoarthritis (KOA) has not been well investigated. Hip-knee cyclograms can visualize the relationship between the hip and knee joint simultaneously. The aim of this study was to elucidate differences in inter-joint coordination and gai...
