Gait Retraining for Runners with Knee Osteoarthritis

Over a 4-week period, runners will be asked to increase their step rate to reduce knee loading during running. Specifically, they will have to increase their preferred step rate by 10% during weekly laboratory running sessions as well as during habitual running training. In the laboratory, runners will be provided with live visual/auditory biofeedback on step rate and asked to target a specific value representing 110% or preferred step rate. During their individual running sessions, runners will be wearing a GPS-enabled watch that will provide feedback on live step rate, and they will be asked to maintain the same value as in the laboratory.
