Abstract

To study and compare lower extremity joint kinematics of the affected limb in patients with unilateral knee osteoarthritis during SOS, SBSA1, SBSNA1, SWA1 and SWNA1 stair locomotion patterns.

15 patients participated in this study. The stair ascent and descent were performed by patients using different stair locomotion patterns i.e. SOS, SBSA1, SBSNA1, SWA1 and SWNA1. Kinematic data was collected using Noraxon motion analyser.

On kinematic comparison of the different types of stair ascent locomotion patterns, the observed trend of the highest to the least movements at the affected knee joint was: SWascA1 > SBSascA1 > SOS ascent > SBSascNA1 > SWascNA1. During stair descent, the observed trend was: SBSdscNA1 > SOS descent > SWdscNA1 > SBSdscA1 > SWdscA1.

All five types of stair locomotion patterns differ kinematically from each other with respect to certain joint angles. Based on the results, the preferred patterns for stair ascent could be SWascNA1 and SBSascNA, and for stair descent could be SWdscA1 and SBSdscA1, due to lower kinematic demands at the knee joint.
