Gait Retraining for Knee Osteoarthritis Trial

The GREAT study
Evaluating the effects of two novel interventions

This is a research study about evaluating the effects of two novel interventions, which are walking (gait) strategies for people with knee osteoarthritis. The walking strategies involve either walking with the foot pointing in a little more than your usual (toe-in gait), or walking with the foot pointing out a little more than your usual (toe-out gait). Both of the walking strategies tested in this study have demonstrated ability to reduce the loading forces in the knee joint, however, we do not know which is more effective. This study aims to evaluate which intervention is most acceptable and effective in reducing pain for people with knee osteoarthritis. 


List of eligibility criteria:

  • Display clinical signs of knee OA according to the National Institute for Health Care Excellence (NICE) guidelines (2014), which involves being 45 years old or older, having activity-related joint pain, and having either no morning joint-related stiffness or morning stiffness which lasts no longer than 30 minutes.
  • Mostly reporting medial (middle) knee pain.
  • Reporting average knee pain during walking of > or equal to 3/10 on a visual analog scale (VAS) with 0 representing no pain, and 10 representing the worst pain imaginable.
  • Are able to walk unaided for at least 30 minutes. 

Ethics committee approval number: 2018/969
