Using VR to improve balance disorders
During rehabilitation, pain management is a major challenge for patients and health professionals....
Invented in 1995 by Dr. V. Ramachandran, mirror therapy is a neuro-rehabilitation technique that allows the brain to be deceived visually with the help of a mirror at the level of a damaged limb (amputated, paralyzed...).
Historically, this therapy was used to treat phantom pain after amputation. This method was then rapidly extended to the treatment of other types of unilateral pain and loss of motor control, such as in hemiplegic patients after a stroke. [2] [3] or for the management of pain of the Complex Regional Pain Syndrome (CRPS) type.
In recent years, mirror therapy has been modernized by computer and digital tools. Among these technologies, we find immersive virtual reality (VR).
The principle of mirror therapy is used in VR: the patient visualizes, thanks to the virtual reality helmet, the movements of the healthy limb in the pathological limb. Thanks to brain plasticity, this visual illusion allows the creation of new neuronal circuits.
In addition to the basic principle, the virtual reality mirror therapy developed by H'ability allows to :
Recent studies show that virtual reality mirror therapy relieves pain while improving motor function and activities of daily living (AD L). "Unilateral and bilateral limb mirroring exercise in an immersive virtual environment can improve cortical reorganization and lead to improved motor function." [4]
The implementation of virtual reality mirror therapy is suitable for all patients, even those with muscle spasticity.
