Auditory Verbal Training (AVT) or Post-operative rehabilitation- Rehabilitation is an essential part for those who have undergone Cochlear Implantation. All patients need Auditory Verbal Therapy (AVT). In Auditory Verbal Therapy, the emphasis is laid on making the child listen and speak normally, rather than on lip reading and visual cues. Learning to listen takes time and requires concerted efforts from the patient, the family and the person providing habilitation services. Thus the implant can offer a wide range of benefits, including hearing speech, environmental sounds and music.
