Gait Modification Combined with Lateral Wedge Insoles for the Treatment of Knee Osteoarthritis


A primary risk factor for the structural progression of knee osteoarthritis is excessive or abnormally distributed knee joint load during walking. This study will examine the combined effects of two conservative treatment strategies (lateral wedge insoles and gait modification) to redistribute loading of the knee joint. The gait modification training will be administered with and without the help of a smart shoe training aid providing vibration-based feedback during walking.


To examine knee and ankle joint biomechanics when walking with a change in foot motion, a lateral wedge insole, or a combination of the two, and to examine the ease of teaching a change in foot motion using vibration-based feedback.

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.

What is required?

To determine study eligibility, you will be required to attend a 30-minute biomechanical gait screen and an x-ray screening for knee OA. Once your study eligibility is confirmed, the study will consist of two separate visits to our motion analysis lab at UBC Hospital. The first will involve teaching you to change the way your foot moves when you walk using the vibration-based feedback of a smart shoe. The second appointment will involve walking with that gait modification in combination with wearing a lateral-wedge insole. Each appointment will last approximately 2 hours. When the study is complete, the lateral-wedge insole is yours to keep.
