A study looking at responses from patients with knee osteoarthritis pedaling using lateral wedges in their shoes, demonstrating a reduction in knee moments in the frontal plane of 45-77%, which should reduce non-driving loads in these patients. In addition, rotating the toes inwards by 5-10 degrees also resulted in 54-58% less knee load. These are important findings for the use of bicycles as a form of rehabilitation particularly when attempting to maintain levels of physical activity because osteoarthritis is a disease that can be exacerbated by the lack of physical activity. More often, patients with knee pain or injury attempt to engage in cycling as a non-weight bearing form of exercise which increases the need of ensuring that cyclists can minimise their risk of further exacerbating their injury or pain. Even though cycling reduced knee loads compared to running and walking, for patients with chronic disease or injuries, it is vital to reduce as much as possible non-driving loads on their joints.
