Exercise therapy and comorbidity in osteoarthritis of the hip or knee: development and evaluation of treatment protocol (COOA)

Background

Exercise therapy is generally recommended in osteoarthritis (OA) of the hip or knee. In the presence of comorbidity, adaptations in the exercise regimen are mandatory. Unfortunately, current protocols and guidelines do not offer advice on these adaptations or even explicitly exclude patients with comorbidity. The most prevalent comorbidities in OA i.e. cardiac diseases, eye diseases (low vision), and metabolic diseases (diabetes). A protocol on the adaptation of exercise therapy is urgently required, as comorbidity is highly prevalent in OA, comorbidity compromises regular exercise therapy, and comorbidity is associated with additional limitations in activity in OA.
