Audiological rehabilitation of older people: Visual and vibrotactile considerations

Abstract

This paper discusses the peripheral and central visual and tactile pathways with respect to the diminishing integrity of the ageing nervous system. This discussion is based upon extant data derived from investigators in vision and vibrotactile sensation. The purpose in examining these investigations is to ascertain the problems associated with the use of vision and vibrotactile stimulation in the auditory rehabilitation of older people. Speed of processing and simultaneous use of pathways are factors to be considered carefully in order not to contribute to perceptual confusions. The writers hypothesize that the rehabilitative audiologist, when using the visual and tactile pathways of older patients for language processing is confronted with difficulties that are often encountered when using the auditory pathway in the presence of central auditory ageing effects. In view of the implications of the research findings in vision and vibrotactile sensation, suggestions are made to those professionals who work with older hearing-impaired people.
