title: Vibrotactile stimulation: case study with a profoundly deaf child.
abstract: This case study reports results obtained from a young, profoundly deaf child, M, who was fitted with a single-channel vibrotactile device, the Tactaid I, at 29 months of age. Her progress in speech and language development was evaluated over a 14-month period. During this period, M learned to understand 101 words through lipreading and the Tactaid I, and to produce consistent approximations of 90 words. Her scores on language tests with hearing-impaired norms progressed from below average to above average for her age. M's scores on language tests with hearing norms also reflected significant progress, although she did not achieve normal language development. These results indicate that a single-channel vibrotactile aid may facilitate the acquisition of spoken language in a profoundly deaf child who is unable to benefit from a conventional hearing aid.
