During training, participants were instructed to match their calculated toe-out angle (solid line) with the target angle corresponding to a 10° increase in toe-out angle (thick vertical line). Specifically, participants were instructed to focus on the straight sections of the real-time toe-out angle – which corresponded to stance phase toe-out angle – rather than the curved portions – which corresponded to swing phase toe-out angle.

Individual participant data for self-selected toe-out angle (top panel), late stance peak KAM (middle panel), and knee joint pain as measured using an 11-point NRS (bottom panel). White bars show data from the baseline assessment, while black bars pertain to follow-up data for each participant. Data for toe-out angle and late stance peak KAM pertain to the mean (95% CI) values from the five walking trials at each testing session. Negative toe-out angles denote self-selected toe-in.
