Clinical Trial Summary

The study aims to compare the effects of an education and High Intensity Interval Training program (eHIIT) with the widely used Neuromuscular Exercise and education program (NEMEX-e) on knee OA symptoms and risk factors for cardiovascular disease in people with knee OA and at least one risk factor for developement of cardiovascular disease. The main research questions the study aims to answer are: - Is the eHIIT program better than the NEMEX-e program for reducing the risk of cardiovascular disease? - Are the two programs equally good at providing improvement in knee symptoms?

Intervention

Behavioral:
• eHIIT
Education and High intensity Interval Training (Aerobic Exercise) The focus of the one educational session is rationale for aerobic exercise, expected physiological effects of aerobic exercise, diet when performing an exercise program, how the knee accommodates to exercise (including potential experience of muscle soreness and how that is different from joint pain), and management of potential knee OA symptom flares. HIIT is an aerobic exercise form. The eHITT protocol consist of eight 2-minute intervals of high intensity training (with the goal to train at a heart rate of at least 80% of HRmax) followed by 2 minutes of moderate training intensity (with the goal to train at a heart rate of at least 60% of HRmax). There will be several types of exercise modalities for aerobic exercise available (treadmills, cross-trainers, row- and cycle ergometers) and participants may choose whichever they prefer.
• NEMEX-e
Education and Neuromuscular Exercise The focus of the two educational sessions is on providing knowledge of OA and treatment options to the participants, with a special focus on knee OA, diet, and exercise and its benefits. Furthermore, advice about self-management is given. The exercises are based on neuromuscular principles to improve sensorimotor control and achieve compensatory functional stability. Sensorimotor control is the ability to coordinate muscle activity and maintain functional stability during movement allowing for joint stability during physical activity. Various positions (sitting, lying, standing) are used to achieve the desired postural activity. The overall goal is to obtain muscle control and stability in situations resembling daily life and/or more strenuous activities. The focus is on achieving good quality of the performance in each exercise with appropriate postural orientation (e.g., joint positioned appropriately in relation to each other).
