Activity-Induced Changes in Pain and Knee Range of Motion in Adults With Knee Osteoarthritis

BackgroundPain with movement is common in adults with knee osteoarthritis (OA), but the effect of movement-evoked pain on gait is not well understood. This relationship is vital to understand as gait mechanics are associated with OA initiation and progression. Our current understanding of acute changes in pain and gait stems from extended bouts of walking, however these bouts likely dont represent real-world behavior. Therefore, understanding how gait changes with shorter, more intense bouts of activity may provide valuable insight into the pain experience. MethodsAdults with (n=19) and without (n=19) knee OA wore inertial measurement units (IMUs) while completing bouts of walking before and
