Background and purpose: The ability to perfonn everyday activities is essential for maintaining independence in daily life. A number of studies have reported the effect of hip and knee osteoarthritis (OA) on biomechanical characteristics of the lower limb during gait. There is a dearth of studies reporting biomechanical analysis of stair climbing in OA subjects, particularly those with hip OA. Thet:efore, the pwpose ofthis study was to investigate the impact of hip and knee OA on the biomechanical characteristics ofhip, knee and ankle joints during stair climbing and gait. Methods: Three age matched groups (range 50-75 years) participated in this study: control group, hip OA group and knee OA group. The laboratory staircase consisted of 4 steps (rise height 18 cm, tread length 28.5 em). Sagittal joint angles, vertical ground reaction forces, sagittal joint moment, and EMG activity of lower limb muscles were recorded using 3D Vicon motion analysis system, Bertec force plates and Telemetry EMG. . Results: Both hip and knee OA subjects moved with significantly (p<0.05) slower speed during gait, stair ascent and stair descent which were accompanied with alterations in lower limb kinematics, kinetics and EMG activity in comparison to the controls. Hip OA subjects showed a significant (p
