Summary
Excessive knee joint loads during walking can contribute to knee osteoarthritis progression. Changing the rotation of the foot (in-toeing or out-toeing) while walking can lower knee joint loads and improve pain and function. Telerehabilitation (using video or telephone communication to delivery rehabilitation) has shown promise in delivering exercise therapy for knee osteoarthritis, but it is unknown if walking modifications can be delivered using this method. This study consists of a six-week walking modification program in people with knee osteoarthritis. Performance of the modification will be measured using motion capture and wearable sensors during practice and daily life.
Eligibility Criteria
Inclusion Criteria
- 50 years of age or older
- Exhibit signs of tibiofemoral osteoarthritis based on a score of ≥2 on the Kellgren and Lawrence grading scale predominantly in the medial compartment.
- Self-reported knee pain ≥ 3 / 10 on a numerical rating scale of pain (NRS; 0 = "no pain" and 10 = "worst pain imaginable") during most days of the previous month
- Comfortable walking intermittently for 30 minutes
- Fit into the available sizes of sensor shoes (between US women's 5 to men's 13)
- Exhibits ≥2% reduction in knee adduction moment impulse at 10 degrees of change in toe-in or toe-out during the screening appointment.
Exclusion Criteria
- Any knee surgery or intraarticular injections within the past 6 months
- A history of joint replacement surgery or high tibial osteotomy
- Current or recent (within 6 weeks) corticosteroid injections
- Use of a gait aid
- Currently on a wait list for joint replacement surgery or high tibial osteotomy
- Any inflammatory arthritic condition
- Any other conditions that may affect normal gait or participation in an aerobic exercise program
- Cannot attend all required appointments
