TECHNOLOGICAL MIRROR THERAPY:
It is a motor stimulation technology based on the illusion of movement, resulting from mirror therapy and motor imaging initiated in the United States more than twenty years ago. These are documented with a good level of evidence in post-stroke rehabilitation (see HAS 2012 recommendations, Cochrane 2014 review).
It allows the brain to be deceived, making it believe that it is the deficient hand that works well while it is the other that has been filmed (and the image reversed).
Main objectives of the method
For paralysed or painful patients, there is an inconsistency between movement control and visual and sensory feedback: it is very difficult to relearn a movement with permanently negative feedback, synonymous with failure.
This method aims to prove to the child that this deficient side belongs to him, that he is able to use it. The goal is for the child to visualize the movement before doing so, allowing him/her to reintegrate his/her hand/arm into his/her body map.
Specificities of the method
Dessintey offers a technological platform based on artificial intelligence to offer a personalized patient care program.
It is a therapy called "augmented visual feedback": the IVS3 system replaces the image of the paralyzed arm with a positive image of movement created from the valid arm. By restoring coherence between what the patient wants to do and what he perceives, this flow of illusions promotes relearning and motor recovery.
In addition, the imagination and observation of movement require a large part of the same brain areas as those used during movement, which makes it possible to develop the activity of these areas during exercises.
The exercises are very simple (opening/closing the hand, taking an object), the children are much more relaxed, and have fewer blockages.
Who is this method for ?
This method makes it possible to accelerate the acquisition of motor skills in the upper limb (hand/arm) in the event of motor disorders related to hemiplegia, cerebral palsy, stroke...
For children with hemiparesis, mirror therapy with Dessintey technology allows them to become aware of their hemi arm, to reclaim it, to integrate it into their motor scheme and to be more motivated to use it, thanks to the illusion of movement
What parents say about it
"The first time I used mirror therapy (with the IVS3 device), I perceived shivering, small nerve impulses in my arm and fingers"
"Compared to conventional mirror therapy, the illusion is better with the machine"
"This device generates sensations that have never been reported by other patients with different therapies," confirms Dr. Duret, a rehabilitation specialist at Clinique des Trois Soleils, "We have an immediate impression in the patients' feelings and it's quite disturbing.
"On the mind it plays a lot, because we have the impression that we are the ones doing the movement", "sometimes we really manage to feel the feeling that the arm is moving, and it feels good, it really positive the session".
The literature review confirms the value of mirror therapy interventions for cerebral palsy.
One study suggests that a single 30-minute session of mirror therapy induces an increase in the amplitude of PEM on the affected limb. The fMRI shows a shift in brain activity from the healthy hemisphere to the motor area of the injured hemisphere. This phenomenon is accompanied by a change in the interhemispheric balance with a decrease in the activity of the healthy hemisphere and an increase in the opposite hemisphere.
