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.

Conditions

• Knee Osteoarthritis
• Joint Diseases

Interventions

Type	Name	Description
BEHAVIORAL	Education session, Fitbit Flex, and remote coaching by a PT	Participants will receive a brief education session, use of a commercially available physical activity tracker (Fitbit Flex), and remote counselling by a PT. Intervention will be received immediately.
BEHAVIORAL	Same intervention with a 1 month delay	The Delayed Intervention Group will receive the same intervention as the Immediate Intervention Group, but with a 1 Month delay.
