External Knee Adduction Moment during Gait Initiation and Steady-State Gait in People with Knee Osteoarthritis.

[Purpose] The purpose of this study was to compare external knee adduction moment of gait initiation and steady-state gait in people with knee osteoarthritis and normal adults. [Subjects and Methods] Ten females with severe bilateral knee osteoarthritis (KOA) and 9 female healthy adults (HA) performed gait initiation and steady-state gait. External knee adduction moment of the stance limb was measured using 3D motion analysis and force plates. [Results] The results show only a main effect of group, not a main effect of task. [Conclusion] External knee adduction moment was similar between gait initiation and steady-state gait. [ABSTRACT FROM AUTHOR]
