Brief summary
Low physical activity levels and poor cardiovascular health are big problems for people with severe knee osteoarthritis. This study is the first in the world to find out if a walking program can make a difference to their knee pain and cardiovascular health.
Interventions
In addition to standard care, participants in the intervention group will be prescribed a walking dose of 70 minutes per week, of at least moderate intensity using the rate of perceived exertion scale with a a score of at least 3/10, in bouts of at least 10 minutes. The weekly dose will be completed for 12 weeks in the community. The walking doses will be completed in the community using normal assistive devices, such as a walking stick if required. Participants will continue taking their usual
In addition to standard care, participants in the intervention group will be prescribed a walking dose of 70 minutes per week, of at least moderate intensity using the rate of perceived exertion scale with a a score of at least 3/10, in bouts of at least 10 minutes. The weekly dose will be completed for 12 weeks in the community. The walking doses will be completed in the community using normal assistive devices, such as a walking stick if required. Participants will continue taking their usual medications and other normal strategies to manage their knee osteoarthritis. To increase the likelihood of adherence to the intervention and maximise the effectiveness of the intervention, we will use the following behavioural change techniques and strategies: Single planning session of up to 30 minutes with goal setting - a physiotherapist will assist the participant to determine when and where to complete the dose of walking; Supervision - physiotherapist supervision of one session of walking weekly; Monitoring - each participant will wear a pedometer to self monitor the number of steps each week. They will also complete a logbook to record number of steps and time spent walking each week. A physiotherapist will monitor their progress with a weekly phone call or send weekly SMS reminders; Engaging social supports - each participant will be encouraged to walk with a friend, or family member or other research participant.
