  Purpose

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

Further study details as provided by Marius Henriksen, Frederiksberg University Hospital:

Primary Outcome Measures:
  • Change from baseline in mechanical pain sensitivity [ Time Frame: Baseline and at 12 weeks ]
    Pain thresholds and temporal summation of pain


Secondary Outcome Measures:
  • Change from baseline in proinflammatory cytokines and biomarkers of cartilage breakdown in blood and urine [ Time Frame: Baseline and at 12 weeks ]
  • Change from baseline in patient reported pain and function [ Time Frame: Baseline and at 12 weeks ]
    KOOS questionnaire

  • Change from baseline in functional pain test [ Time Frame: Baseline and at 12 weeks ]
    Pain is assessed during continuous tradmill walking at self-selected pace for 20 minutes.

  • Change from baseline in imaged based quantification of inflammation in the knee [ Time Frame: Baseline and at 12 weeks ]
    Contrast enhanced MRI imaging used to quantify inflammation (DYNAMICA software)
