Activity Increase Despite Arthritis (AIDA): phase II randomised controlled trial of an active management booklet for hip and knee osteoarthritis in primary care

119 patients with knee and hip osteoarthritis were randomized to receive either an advice booklet on managing osteoarthritis through exercise, called "The Hip & Knee Book: Having you cope with the osteoarthritis", or receive an information booklet on osteoarthritis, to measure the efficacy of the advice booklet on motivating patients to exercise. Following assessments over a 3 month period, the results displayed that patients who read "The Hip & Knee Book" had slightly better improvements in illness, exercise, fear-avoidance beliefs, and physical activity levels compared to those who read the information booklet.
