Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

A commonly administered conservative non-pharmacological treatment for OA is exercise, with beneficial effects in terms of reduced pain and disability.

While the link between exercise and reduced disability is mediated by e.g. increased muscle strength and endurance, the analgesic mechanisms related to exercise are unexplored. knee OA patients have both peripheral and central sensitization of pain mechanisms resulting in hyperalgesia. Thus, targeted pain treatment in these patients may focus on both peripheral and central mechanisms but it unknown if exercise affects either of these mechanisms.

It is hypothesized that in knee OA patients exercise reduces the pain sensitivity
