"Office workers often spend long hours sitting, which can lead to stiffness and reduced mobility. By studying these two techniques AIS and MFR, we can determine which one is more effective in helping office workers to improve their flexibility and range of motion in the knee joint because their sedentary work environment often leads to musculoskeletal issues, including limited knee joint mobility.

AIS involves stretching specific muscles while actively engaging opposing muscles to enhance the effectiveness of the stretch. It aims to increase the extensibility of muscles and improve joint mobility. On the other hand, MFR focuses on releasing tension and adhesions in the fascia, the connective tissue surrounding muscles and joints, to restore mobility and reduce pain.

Understanding the benefits and effectiveness of these techniques will contribute to evidence-based practices in occupational health and help office workers maintain optimal joint health"
