The expectation of the cochlear implant (CI) user is recovering auditory sensitivity and understands spoken language. Considering the auditory rehabilitation as a prerequisite for the development of language skills, the aim of this study was to investigate the effect of training on the behavior of the listener to speaker in this group, check the emergence of relationships and the generalization to indirectly taught voice different frequency. Participated of the study three adults with profound, bilateral, neurosensory hearing, loss post-lingual, CI users, with time deprivation (TD) ranging from 5 months to 23 years. Data were collected with a computer with touch screen and application programming routines for the teaching and testing. The teaching program, with seven stages, had choice according to the model. Phase 1) Pre-train for habituation, the participant with auditory-visual tasks by fading out, 2) Pre-test naming and reading, to select 8 words for training, 3) Training of relations between dictated words and figures; 4) Training of relations between dictated words and written words; 5) Testing equivalence class, which were not directly taught; 6) generalization testing, with the dictated words, with an adult male voice; 7) Post-test of picture naming and word reading. Two of the three participants learned the tasks (Phases 3 and 4), and showed equivalence class (Phase 5) e generalization (Phase 6). All of the participants improved their ability of speaking after the study (Phase 7). The performance of the participant with 23 years of TD, which presented difficulties in oral language, was low, indicating further investigation of the variables due to flaw on the training, or to the IC operation, or inappropriate use of the device, etc. More studies are required to evaluate the potential of the procedure adopted for the auditory rehabilitation of CI users.

Reabilitação de pacientes com implante coclear utilizando uma nova abordagem na análise da percepção auditiva

Communication is the way we have to interact with the world, this communication can be verbal or nonverbal. For the satisfactory progress of oral communication, it is necessary that the auditory pathway, from the central portion to the peripheral portion, is functioning properly. When there is a change in the auditory pathway, it is necessary to use devices that aid the perception of sound, among these instruments we highlight the cochlear implant, but for the proper use of this resource, an efficient rehabilitation is essential. Objective: To develop a cochlear implant simulator with the purpose of enabling the rehabilitator to identify the stimulus received by the hearing impaired, and thus to act in the schedules of the rehabilitation sessions, so that the sounds can be detected correctly, favoring the development or maintenance of the oral communication. Methods: For the development of the study, 3 groups of individuals were formed: the first group consisted of 6 implanted patients who received as pure sound stimulus. Groups 2 and 3 were composed of normo-listeners who received the sounds filtered by the cochlear implant simulator; group 2 with 22 individuals received filtered sounds for 22 activated channels (100%) and group 3 perceived filtered sounds with 17 channels activated (77%), corresponding to the number of channels activated in a cochlear implant. All participants were submitted to sessions with audiovisual stimuli in software running on a computer with a touch screen. The stimuli are 124 words extracted from a list used in the logoaudiometry exam, being 16 trisyllables, 46 disyllables and 62 monosyllables. The trisyllables words were generated synthetically and the others recorded in female voice of speech therapist. Results: It was observed that all groups presented greater difficulty in the detection of monosyllables, where the latency period was increased, and more errors occurred for sound perception, this is due to the reduction of the auditory track. Therefore, if there is an individualized rehabilitation treatment, it is believed that the development of the implanted hearing impaired is more efficient.
