Effects of Toe-out Gait Modification on Clinical and Biomechanical Measures in People With Knee Osteoarthritis
In Brief
A clinical study evaluating Progressive walking program with toe-out gait modification and Progressive walking program for Knee Osteoarthritis. Completed, enrolled 79 participants across 1 site.
Detailed Summary
Knee osteoarthritis (OA) is a costly health condition affecting more than 10% of Canadian adults. Excessive and unbalanced loads passing through the knee joint have been implicated in the progression of OA. Typical conservative treatment of OA has focused on increasing daily activity, without consideration for the underlying joint loading. This study aims to compare a 4-month walking program that aims to increase the angle of the foot (toe-out angle) during walking - a measure shown to reduce joint loading and OA disease progression - while increasing walking time/distance, with a standard walking program that aims to increase walking time/distance. It is predicted that the walking program focusing on increasing toe-out will provide greater reductions in self-reported knee pain and a greater reduction in unfavorable knee joint loading.
Study Details
Timeline
Interventions
Participants in this study group will perform continuous treadmill walking for a minimum of 30 minutes at each session, but the emphasis will be to increase toe-out angle by 10 degrees over that exhibited at baseline. A mirror will be provided for biofeedback and participants will be instructed on its use for achieving the target toe-out angle. Increased walking time and distance will be encouraged the same as for the control group.
At each scheduled visit, participants will perform treadmill walking for a minimum of 30 minutes depending on the individual's baseline activity level and the stage of the intervention. Emphasis will be solely on increasing walking time and distance to achieve the target of a 40% increase in daily activity.
