Gait REtraining Interventions for people with knee osteoArthritis Trial (The GREAT Study)

The study aims to evaluate the effects of three interventions; walking (gait) strategies for people with knee osteoarthritis.

We would like to invite you to consider participating in a new research project, entitled: “Gait retraining interventions for people with knee osteoarthritis.” The study aims to evaluate the effects of three interventions, which are walking (gait) strategies for people with knee osteoarthritis.

These walking strategies may have the ability to reduce the loading forces in the knee joint, and through offloading may help to reduce knee pain. However, we do not know which walking intervention is most effective.


You may be eligible to participate in this study if you:

  • Display clinical signs of knee OA according to the National Institute for Health and Clinical Excellence (NICE) guidelines (1), which involves being 45 years old or older, having activity-related joint pain, and having either no morning joint-related stiffness or morning stiffness that lasts no longer than 30 mins 
  • Are mostly reporting pain in the middle of the knee (medial side)
  • Are reporting average knee pain of ≥ 3/10 on Visual Analogue Scale (0-10) 
  • Are able to walk unaided for at least 30 mins
  • Have evidence of medial knee osteoarthritis based on clinical screening according to the American College of Rheumatology (ACR) Clinical Classification for Knee Osteoarthritis
