About the trial

What the trial wants to find out

Osteoarthritis is a common and disabling joint disease, affecting 4.7% of men and 6.6% of women in France. It causes pain and impaired joint mobility, as well as a reduction in proprioception due to damage to intra-articular mechanoreceptors. In the long term, gonarthrosis can lead to limitations in activities of daily living and increase the risk of falls and institutionalisation.

Read full original descriptionShow less

Total knee arthroplasty is an effective treatment for reducing pain and improving functional capacity. However, 50% of patients operated on are not satisfied with the results obtained at 6 months, and between 37% and 55% experience no significant improvement in their functional mobility. It is therefore important to better define the modalities of rehabilitation interventions in order to improve their efficiency and the functional benefits for the patient.

Proprioception, the visual system and the vestibular system are the three major systems involved in posture and balance. Rehabilitation interventions aimed at improving balance involve these three inputs and their interaction. Studies have shown that proprioceptive rehabilitation can significantly improve balance and gait in patients who have undergone total knee arthroplasty. However, visual feedback may hinder the development of balance skills by limiting the use of other sensorimotor systems.

The 2 groups in the trial

  • proprioceptive exercise with eyes openExisting treatment, for comparison

    * 30 minutes of techniques to increase joint amplitude * 15 to 30 minutes of muscular strengthening of the hamstrings against resistance (elastic or pulley), of the quadriceps without resistance and then against a light weight (1 to 2 kg). * 15 to 30 minutes of proprioceptive exercises, eyes open. * 10 to 15 minutes of functional exercises: walking, overcoming obstacles, going up and down stairs * 20 minutes of pressure therapy

    Treatment: rehabilitation : eyes open

  • proprioceptive exercise with eyes closedTreatment being tested

    * 30 minutes of techniques to increase joint amplitude * 15 to 30 minutes of muscular strengthening of the hamstrings against resistance (elastic or pulley), of the quadriceps without resistance and then against a light weight (1 to 2 kg). * 15 to 30 minutes of proprioceptive exercises, eyes closed * 10 to 15 minutes of functional exercises: walking, overcoming obstacles, going up and down stairs * 20 minutes of pressure therapy

    Treatment: rehabilitation : eyes closed

Questions to ask the study team

  1. How often do I need to come in, and for how long each time?
  2. Are travel costs paid?
  3. Can I keep my own doctor?
  4. What happens if I want to stop?
