Abstract
Osteoarthritis; OA for short, is the most common form of arthritis and is one of the leading causes of disability. OA is the progressive wearing down of the cartilage covering bones and joints. For those with end stage knee OA, a total knee arthroplasty, or replacement, is the standard treatment with more than 700,000 TKA’s performed annually. While pain is improved in general, the functional performance and activity levels of the joint often do not return to those of healthy individuals. To understand the long-term consequences of poor function post-TKA, we need data that characterizes an individual’s real-world movement and behavior. Furthermore, to provide an accurate comparison to post-TKA patients, characterization of healthy individuals is needed as the standard in functional performance and activity. In this study, healthy individuals will perform the six-minute walk test (6MWT) on three terrains: indoor level ground, outdoor paved surface, and outdoor unpaved surface while wearing a wireless inertial-based gait system. We hypothesize that the variability in real-world environments will better characterize healthy walking, and that differences in movement variability will be seen when walking on different surfaces. Initial data from this study shows increased variability as the surface being walked becomes less homogenous, with the least variability being shown in the indoor level ground, and the largest variability being shown on the outdoor unpaved surface.
