Behavioral assessment of auditory processing before and after formal auditory training in traumatic brain injury patients Avaliação comportamental do processamento auditivo pré e pós treinamento auditivo formal em indivíduos após traumatismo cranioencefálico

Purpose: To investigate the effects of formal auditory training on individuals with traumatic brain injury using behavioral tests. Methods: Nine normal hearing individuals who had severe traumatic brain injury underwent behavioral evaluation of auditory processing pre and post formal auditory training. Eight sessions took place in an attempt to train the auditory skills of temporal ordering, auditory closure and figure -ground. Results: All individuals improved in all tests after the training, improving the auditory skills of temporal ordering and figure-ground of verbal sounds. In terms of the altered gnosis processes, a significant im provement was found for encoding (gradual loss of memory and sensory integration) and organization. Conclusion: After formal auditory training, individuals with severe traumatic brain injury exhibited adequacy in the auditory skills of figure-ground, temporal ordering and resolution.
