Conditional recommendation RACGP OA guidelines.
May have short term effect on pain but studies generally low quality and high risk of bias. Can be used to encourage participating in other treatments.
One recent RCT found weekly 60-minute full body massage had greater effect on pain and function in people with knee than light touch or no intervention at 8/52 but no difference at one year. A 2017 systematic reivew of OA and massage found it was unclear whether massage is more effective than other forms of treatment and recommended larger rigourous RCTs.
