About

The goal of this prospective randomised controled study is to investigate the effect of 8-weeks brisk walking exercise on irisin levels, physical and psychosocial parameters in individuals with knee osteoarthritis, and the relationship between irisin levels and physical and psychosocial parameters. The main question it aims to answer is: does 8-weeks brisk walking exercise increase irisin levels and imoroves physical and psychosocial parameters and is the irisin level in relation with the physical and psychosocial parameters.

Full description

Irisin is a myokine secreted by skeletal muscle after physical activity. It improves subchondral bone density and quality by increasing osteoblast differentiation and proliferation and improves the mechanical support of cartilage. In addition, irisin promotes chondrocyte proliferation, inhibits chondrocyte apoptosis, and reduces the secretion of inflammatory factors and matrix metalloproteinases. As a result of all these, improvements in joint function may be achieved.

Besides, irisin can improve depressive mood in patients with depression, and irisin level is found to be positively correlated with sleep quality and negatively correlated with disease duration and disease activity in patients with rheumatoid arthritis.

This study aims to investigate the effect of an 8-week moderate-intensity brisk walking exercise program on irisin serum levels and physical and psychosocial parameters in individuals with knee osteoarthritis and the relationship between irisin levels and physical and psychosocial parameters.
