This randomized controlled trial aims to investigate the effects of motivational interviewing added to a neuromuscular exercise and home exercise program on pain self-efficacy, exercise behavior, pain intensity, physical performance, and functional status in individuals with knee osteoarthritis. Sixty individuals diagnosed with knee osteoarthritis will be randomly allocated to either an intervention group or a control group. The intervention group will receive motivational interviewing in addition to neuromuscular exercise and a home exercise program, whereas the control group will receive neuromuscular exercise and the same home exercise program. Outcomes will be assessed at baseline, immediately after the intervention, and six weeks after the intervention.
