EXercise as TReatment for osteoArthritis

Osteoarthritis (OA) of the knee is a chronic musculoskeletal disease, and a major cause of pain and disability worldwide. Exercise has previously demonstrated good effect in alleviating OA symptoms. However, optimal exercise modes in OA are currently unknown. This study seeks to evaluate the effects of supplementary focused, knee extensor strength training in addition to neuromuscular exercise (NEMEX) and education in people with OA of the knee as performed in Good Life with osteoArthritis in Denmark (GLA:D ᵀᴹ). Through a randomized design, study participants will either be allocated to 12 weeks (twice weekly) of NEMEX and education or 12 weeks (twice weekly) of NEMEX and education and focused, knee extensor strength training. The primary outcome measurement for this study is the Knee injury and Osteoarthritis Outcome Score, subscale Activities of Daily Living (KOOS-ADL), which is a self-reported questionnaire on daily life activities. Other outcomes include parameters of maximal muscle strength and muscle power, muscle imaging, physical function, pain and self-reported health status.
