Abstract
IntroductionLocked-In Syndrome is admittedly the worst case of motor and speech impairment, it seriously damages the ability of oral and gestural communication of patients. In recent years, alternative and augmentative communication technology has provided resources to restore these patients' ability to communicate.MethodsIn order to relate and classify the main methods with that purpose, this work conducted a systematic review on several journal databases.ResultsWe found 203 related papers and 55 of them were selected to compose the study. After that, we classified them into three major groups and we identified the main difficulties when using each approach.ConclusionIn order to overcome these difficulties, we propose a new system concept to develop an adaptive, robust and low cost communication environment. The proposed system is composed of five modules: data entry, communication, aid to the caregiver and external interaction.

Locked-In Syndrome is admittedly the worst case of motor and speech impairment, it seriously damages the ability of oral and gestural communication of patients
We present a critical view about the papers related in this systematic review, and we answer the research questions proposed in the Planning section
We selected 45 significant publications. These publications were classified into three categories: Concepts and Reviews of Augmentative and Alternative Communication; Communication Software; and methods of HumanComputer Interface
Summary
Locked-In Syndrome is admittedly the worst case of motor and speech impairment, it seriously damages the ability of oral and gestural communication of patients. The contemporary society has been developing technologies to support people with physical or mental disabilities. These limitations usually deprive people from social contact and from accessing to cultural goods. In extreme cases, they even become unable to interact with others or with the environment (Caltenco et al, 2012). The inclusion of disabled people has become a cause championed by organized social movements They aim to develop concrete conditions of social integration of people with visual, physical, hearing and intellectual impairments or multiple disabilities (García and Galvão, 2012)
