Clinical Trial Summary

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change from baseline in physical inactivity	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.	6 weeks
Secondary	Change form baseline in the Knee Injury and Osteoarthritis Outcome Score (KOOS)	The Knee injury and Osteoarthritis Outcome Score (KOOS) questionnaire is used to assess patient reported outcomes on pain, function, and quality of life.	6 weeks
Secondary	Transition questionnaire (TRANS-Q) of perceived change in knee symptoms	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	6 weeks
Secondary	Self-reported change in physical inactivity	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.	6 weeks
