    The Delayed Intervention Group will receive the same intervention as the Immediate Intervention Group, but with a 3 month delay.

Study Details

Physical activity is an essential first-line treatment for patients with knee osteoarthritis (OA). However, only 13% of patients meet the activity recommendation of 150 minutes or more per week. The primary goal of this randomized controlled trial is to assess the efficacy of a Fitbit Flex (a wireless physical activity tracking device) paired with a new application, plus a brief education session and telephone counselling by a physiotherapist (PT), to improve physical activity and reduce sedentary time in patients with knee osteoarthritis.

Arms

  • Active Comparator: Immediate Intervention Group
    Education session, Fitbit/FitViz, PT counselling: Participants receive this intervention in Months 1-3. The session will include a presentation on physical activity, an individual goal-setting session with a registered physiotherapist, and an orientation to the Fitbit Flex and the FitViz app. In Months 1 and 2, participants will use the Fitbit/FitViz. The PT will review the progress with participants via 20-minute bi-weekly phone calls, and progressively modify their activities. In Month 3, participants will continue using the Fitbit/FitViz and have access to a PT via email as needed, but no bi-weekly phone calls. In Months 4-9, participants may continue using the Fitbit/FitViz without access to a PT.
  • Placebo Comparator: Delayed Intervention Group
    Same intervention with a 3 month delay: The full intervention will be initiated in Month 4 and with a brief education session, use of a Fitbit Flex paired with the FitViz app, and counseling by a physiotherapist. In Months 6-9, participants will continue using Fitbit/FitViz without the PT phone calls.
