Digital Motivation to Decrease Inactive Behaviour in Patients With Knee Osteoarthritis

Physical inactivity is a major risk behaviour with a potential for causing premature death, particularly among people with mobility limitations, such as knee osteoarthritis.

Digital motivational interventions (such as SMS) can motive to a healthy behaviour including increased physical activity.

The purpose of this study is to investigate if motivational text messages following an exercise intervention to improve mobility limitations will change the physical activity level in patients with knee osteoarthritis.

This study is designed as pilot randomized controlled trial, with equal randomization (1:1). Eligible participants will be randomised into one of two groups (intervention or control) after completing their baseline measurements. The intervention group will receive weekly motivational text messages and the control group will not receive any attention from the study.

Treatment and study plan

Motivational SMS text message

Behavioral

Motivational text messages delivered to the participants' mobile phones. The text messages contain motivational text and advice on physical activity.

Primary outcomes

  1. Change from baseline in physical inactivity

    Time frame: 6 weeks

    Physical inactivity is measured using an accelerometer based activity monitor. Physical activity is defined as time (in minutes) spent inactive, i.e. lying, sitting, standing during a day.

Secondary outcomes

  1. Change form baseline in the Knee Injury and Osteoarthritis Outcome Score (KOOS)

    Time frame: 6 weeks

    The Knee injury and Osteoarthritis Outcome Score (KOOS) questionnaire is used to assess patient reported outcomes on pain, function, and quality of life.

  2. Transition questionnaire (TRANS-Q) of perceived change in knee symptoms

    Time frame: 6 weeks

    To investigate if participants experience a change in their osteoarthritis symptoms over time, they will be asked: "Pleas answer if you feel that your osteoarthritis symptoms have change for either the better, worse or no changes compared to before you entered this study" at the follow-up visit. The Participants can then check a box say: not change, a change for the worse or change for the better

  3. Self-reported change in physical inactivity

    Time frame: 6 weeks

    At the follow-up visit participants will be asked "Have you changed your physical activity behaviour after completing the motivational intervention". This question will be asked at the end of the intervention period to investigate if the objective measurement of sedentary behaviour is related to the participants own perceived behaviour.
