the patients with locked-in syndrome can communicate with others by two ways in favour of revolution technology
1- writing by using the computer
it�s possible grace a device which permits an access to the computer and complete all the functions.
2- code
the communication is possible by the eyelid�s movement.
it was the only way before the computer, otherwise the patient is in complete isolation from the world like someone who has an infected disease and the people run away.
tetraplegic victim�s hav�nt a problem of communication because they can speak normally, but unfortunately patients with LIS are tetraplegic and mute and this push me to stay in my room for seventeen years like in jail, and when I was obligate to go out from my room I feel myself a statue between the others, the mutisme was an iron wall between me and the society which prevent the integration.
I use the easiest �code� that exists till now and which was discovered by me six months after the cerebral stroke and it�s described in details in my book, and whatever the scientific level of the person he can learn and applicate it in few minutes.
