Abstract

The purpose of this investigation was to determine whether a predictive relationship exists between common gait impairments and limitations in individuals with knee osteoarthritis and their self-perceived functional ability as measured via the Knee Injury and Osteoarthritis Outcome Score, and whether volitional core muscle activation and/or core stabilization training alter these common deficits. Forty-four participants were recruited across a total of three studies, with the final only including 22 participants (control group not included). Participants completed their participation in the first two studies in a single session; however, the third included a six-week intervention program, followed by a post-assessment. Participants underwent biomechanical gait analysis focused on kinetics, kinematics, and gait speed, in addition to transversus abdominis electromyography in the second study. Gait speed was found to predict functional ability scores, while core activation had no effect on the biomechanical gait variables examined. The six-week core stabilization program increased gait speed, decreased the knee adduction moment, and improved functional ability in individuals with knee osteoarthritis.
