Overview
Brief Summary
Physical activity is an essential first-line treatment for patients with knee osteoarthritis (OA). However, a 2013 systematic review found only 13% met the activity recommendation of 150 minutes or more per week. The primary goal of this pilot randomized controlled trail is to assess the feasibility and preliminary efficacy of a multi-component intervention/model of care involving a group education session, use of the Fitbit Flex (a wireless physical activity tracking device), and weekly telephone counselling by a physiotherapist (PT) to improve physical activity and reduce sedentary time in patients with knee OA.
Detailed Description
Knee osteoarthritis (OA) is common (affecting 1 in 10), painful, and debilitating. Being physically active improves pain, mobility and quality of life for people living with knee OA; however, less than half of patients are active. Combining the best evidence in OA care and digital technology, the investigators propose a new model of care for improving physical activity in patients with OA. The investigators primary objective is to determine the feasibility and preliminary efficacy of a multi-component model of care involving 1) a group education and structured goal-setting session, 2) the use of Fitbit Flex (a commercially available physical activity tracker) and 3) weekly telephone activity counselling by a physiotherapist for improving physical activity and reducing sedentary time in patients with knee OA. In this pilot randomized controlled trial the investigators hypothesize that compared to a control group (i.e. the Delayed Intervention group), participants in the Immediate Intervention Group will 1) increase moderate/vigorous physical activity (MVPA), 2) reduce sedentary time, 3) improve OA disease status, and 4) improve abilities to self-manage their condition.

- •Have not had surgery in the back, hip, knee, foot or ankle joints in the past 12 months.
- •Have an email address and daily access to a computer with internet connection.
- •Be able to attend a 2-hour education session at the Mary Pack Arthritis Centre.
Exclusion Criteria
- •Have a body mass index of equal to or greater than 40
- •Have received a steroid injection in a knee in the last 6 months

Outcomes
Primary Outcomes
Time Spent in Moderate-to-Vigorous Physical Activity (MVPA)
Time Frame: Baseline; 1 month and 2 months from baseline
Participants wore a SenseWear Mini device for 7 days at baseline, and Months 1 and 2. We calculated the average time spent in MVPA accumulated in bouts per day. A bout is defined as 10 consecutive minutes or more at the level of 3 or higher METs, with allowance for interruption of up to 1 minute below the threshold.
Secondary Outcomes
- Time Spent in Sedentary Behavior(Baseline; 1 month and 2 months from baseline)
- KOOS - Symptoms(Baseline; 1 month and 2 months from baseline)
- KOOS - Pain(Baseline; 1 month and 2 months from baseline)
- KOOS - Activities of Daily Living(Baseline; 1 month and 2 months from baseline)
- KOOS - Sport and Recreation Function(Baseline; 1 month and 2 months from baseline)
- KOOS - Knee-related Quality of Life(Baseline; 1 month and 2 months from baseline)
- Partners in Health Scale(Baseline; 1 month and 2 months from baseline)
