Foot progression angle modification: an exploratory six-week intervention in people with knee osteoarthritis


An emerging strategy to manage knee osteoarthritis is to change walking motions to lower knee joint loads. Changing the position of the foot while walking has been shown to lower knee joint loads and improve symptoms, but it is unclear if patients can learn these modifications and if they can be performed outside of the laboratory.


To investigate the progression of learning a walking modification over six weeks and the differences between two approaches to instruct the walking modification.

Who can participate?

We are currently recruiting men and women aged 50 and above with knee osteoarthritis (OA). You may be eligible to participate in this study if you have evidence of OA via x-ray and a history of knee pain over the last 6 months. If you do not have recent x-ray images of your knees, you will be referred to a local imaging clinic to obtain these images to determine your study eligibility. You must be comfortable walking intermittently for 30 minutes without the help of a gait aid (e.g. cane, walker).

What is required?

This study involves 10 visits total, including a gait screen and x-ray appointment (if necessary), a baseline gait assessment, 6 practice sessions with a kinesiologist to learn the gait modification, and a follow-up assessment. Once enrolled in the study, the baseline assessment, practice sessions, and follow-up assessment will occur on a weekly basis (one per week). From the first screening appointment to the follow-up assessment, the study will take approximately 12-13 weeks.
