Research summary
To determine whether a change in sleeping position so as to prevent the knee being ‘pushed’ into full extension when lying supine provides pain relief and/or symptom improvement in individuals with knee osteoarthritis (OA).
Only those who normally sleep lying on their back will be recruited. Participants will be recruited into two groups: Group 1, 'intervention'; Group 2, 'control'. Participants in group 1 will be asked to change the position they lie on their bed when sleeping; that is, to reposition themselves when lying on their back so that their feet (and ankles) hang over the end of the mattress. Participants in group 2 will be asked to make no change in the way they normally lie on their mattress when sleeping.
Participants will be asked to complete a questionnaire, asking them about the pain and/or discomfort they are currently experiencing, and their current level of physical functioning. The questionnaire used will be the Knee Injury and Osteoarthritis Outcome Score (KOOS) which has been widely used to assess intervention outcomes in individuals with knee OA. They will be asked to complete this questionnaire four times over a 4-month period; for Group 1 this will be before (x2) and after (x2) changing to the new sleeping position (i.e. day of consent, 1 month later on day of change, and 1 and 3 months after change); for Group 2 this will be matching the intervals in the intervention group. The primary outcome measure will be the KOOS score, which will be compared pre and post- changing to the new sleeping position.
