Feasibility of a Wearable-enabled Intervention for Promoting Physical Activity in People Knee OA (TRACK-OA)

October 29, 2019 updated by: Linda Li, University of British Columbia

Feasibility and Preliminary Efficacy of an Activity Tracker-driven Intervention for Promoting Physical Activity in People Living With Osteoarthritis of the Knee

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.

Study Overview

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.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: Immediate Intervention Group
Education session, Fitbit Flex, and remote coaching by a PT. These three components of the intervention will be delivered to the participants in Month 1. At the end of the education session, the PT will help participants set personal activity goals. In Month 1, participants will use the Fitbit Flex. The PT will review the progress with participants via 20-minute weekly phone calls and progressively modify their activities. In Month 2, they will continue using the Fitbit and have access to a PT via email as needed, but no weekly phone calls.
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.
Placebo Comparator: Delayed Intervention Group
Same intervention with a 1 month delay: The full intervention will be initiated in Month 2 with a brief education session, use of Fitbit Flex, and counselling by a physiotherapist. The trial will conclude at the end of Month 2.
The Delayed Intervention Group will receive the same intervention as the Immediate Intervention Group, but with a 1 Month delay.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
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.
Baseline; 1 month and 2 months from baseline

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Time Spent in Sedentary Behavior
Time Frame: Baseline; 1 month and 2 months from baseline
We calculated the average daily time spent with an energy expenditure of 1.5 METs or lower, occurring in bouts of > 20 minutes during waking hours.
Baseline; 1 month and 2 months from baseline
KOOS - Symptoms
Time Frame: Baseline; 1 month and 2 months from baseline
Symptoms were measured by Knee Injury and OA Outcome Score (KOOS). The KOOS measures knee osteoarthritis disease status and consists of five sub-scales: knee pain, stiffness, daily activity, sports/recreation, and quality of life. Scores range from 0 to 100, with higher being better.
Baseline; 1 month and 2 months from baseline
KOOS - Pain
Time Frame: Baseline; 1 month and 2 months from baseline
Pain was measured by a Knee Injury and Osteoarthritis Outcome Score subscale. Scores range from 0 to 100, with higher being better.
Baseline; 1 month and 2 months from baseline
KOOS - Activities of Daily Living
Time Frame: Baseline; 1 month and 2 months from baseline
Activities of Daily Living was measured by Knee Injury and OA Outcome Score (KOOS). The KOOS measures knee osteoarthritis disease status and consists of five sub-scales: knee pain, stiffness, daily activity, sports/recreation, and quality of life. Scores range from 0 to 100, with higher being better.
Baseline; 1 month and 2 months from baseline
KOOS - Sport and Recreation Function
Time Frame: Baseline; 1 month and 2 months from baseline
Sport and Recreation Function was measured by Knee Injury and OA Outcome Score (KOOS). The KOOS measures knee osteoarthritis disease status and consists of five sub-scales: knee pain, stiffness, daily activity, sports/recreation, and quality of life. Scores range from 0 to 100, with higher being better.
Baseline; 1 month and 2 months from baseline
KOOS - Knee-related Quality of Life
Time Frame: Baseline; 1 month and 2 months from baseline
Quality of life was measured by Knee Injury and OA Outcome Score (KOOS). The KOOS measures knee osteoarthritis disease status and consists of five sub-scales: knee pain, stiffness, daily activity, sports/recreation, and quality of life. Scores range from 0 to 100, with higher being better.
Baseline; 1 month and 2 months from baseline
Partners in Health Scale
Time Frame: Baseline; 1 month and 2 months from baseline
The Partners in Health Scale is a 12-item measure designed to assess disease self-management abilities including knowledge of health conditions, ability to participate in decision-making with health care professionals, and ability to pursue a healthy lifestyle. Scores range from 0 to 96, with lower being better.
Baseline; 1 month and 2 months from baseline
