A new method for the reabilitation training of vertigo with virtual reality

Abstract

Our objective is to verify the possibility of applying the new technology in creating locations in VR to the field of rehabilitation.
To test the application of VR on our patients we used a virtual reality helmet commercially sold. The rehabilitation training is divided in two phases: “passive” and “active”.
“Passive phase”: the patient is asked to observe images for two minutes keeping his head motionless. If a scene causes neurovegetative symptoms it can be repeated.
– Starry sky: simulation of starry field on centrifugal movement.
– Vertical striper: alternating black and white vertical stripes moving from right to left in the patient’s visual field (like Barany’s cylinder).
“Active phase”: Grid. Simulation of a room. It appears to be formed by a red and blue wall which unite at the center of the visual field and is completed by a green floor and ceiling. Thus the patient has the impression of being at the center of a cube with a corner of it in front of him. In this application the patient can move his head to explore the environment using exercises of “point de mire”.
642 patients have undergone vestibular rehabilitation with the system of VR, from 5 to 87 years of age, 299 males aged between 6 to 81 years o 343 females aged from 5 to 87.
Our protocol foresaw an accurate anamnestic record and an objective otoneurologic examination. A static stabilometric examination carried out before and after the rehabilitation sessions allowed an objective valuation. Each rehabilitation cycle takes 5 consecutive days of treatment with daily sessions lasting 20 minutes.
The data we analyzed bring us to various considerations.
We can say that rehabilitation using 3D graphic elaboration and Virtual Reality has shown positive results in the major of the patients treated by us.
74% of patients showed an improvement demonstrated by stabilometric data, and even more important 92.2% of patients reported an improvement of their symptoms.
If we consider the results obtained for each pathology peripheral vertigo showed an improvement both of symptoms and objective data, whilst in central vertigo, data showed an improvement in objective data not always accompanied by a regression in subjective symptoms. The particular exercises carried out by patients are very good for rehabilitation of peripheral vertigo whilst we consider 5 sittings are perhaps too few to re-establish a compensation for central vertigo.
Correct execution of the exercises permits a mobility of the neck which activates compensation mechanisms through somato-esthesic channels in cervical muscles.
Patients with form of imbalance deriving from psychogenic causes deserve a separate comment. Stabilometric data showed an objective improvement in 73% of cases but 100% of patients reported an improvement of symptoms. This signifies that relationship with the therapist, recognition of pathology and contact with new and advanced technology gave confidence to the patients, thus permitting profit from the treatment. This was shown however not only for psychogenic vertigo but also in all others where a certain emotional component is always present.
The analysis of the data we obtained for passive rehabilitation allows us to be very optimistic about this method. Only a minimum number of tested patients (3%) showed any disturbance during the trial whilst the others tolerated it very well indeed some were recorded an immediate improvement in their symptoms.
The use of this technology seems to us to present very extensive prospects.
