Supporting Physical Activity and Reducing Sedentary Time in Arthritis (SuPRA)


The study is now closed for recruitment.

Runner leg and muscle pain during running training outdoors in summer nature

Being physically active has been shown to reduce pain and improve quality of life in people with knee osteoarthritis (OA). However, many people with osteoarthritis do not meet the recommended levels of physical activity.

In this study, we will test if a new physical activity program can help improve activity levels with knee OA or knee pain.


The program involves:

  1. A group education session on physical activity
  2. The use of a Fitbit Flex with a new application called FitViz
  3. Online/telephone counselling by a registered physiotherapist using FitViz


We will recruit 60 people with knfitbit-flexee OA or persistent knee pain. Eligible participants will be randomly assigned to either start the program immediately or wait 3 months.


Participants will also be asked to complete assessments at the beginning, and at the end of 3 months, 6 months, and 9 months of the study. These assessments involve an online questionnaire and wearing another armband accelerometer for 7 days. At the end of the study, participants will be invited to take part in a phone interview about their opinion of the program.
