Improved language development in 2cochlear implant users with disproportionate language impairment (DLI) who received phonological awareness training

Abstract

A proportion of cochlear implant users demonstrate delayed language development without mental retardation or inappropriate aided hearing level. This condition is referred to as disproportionate language impairment (DLI). We conducted phonological speech-language training for two patients with cochlear implants who showed DLI. Cases 1 & 2 were first referred to our training office at 4 and 6 years of age, respectively. Both patients showed normal range intelligence development and aided hearing levels. However, neither could repeat non-words consisting of 3 mora and were eventually suspected to have phonological difficulties. We conducted phonological awareness training based on the reports of Tanemura et al. A speech-language pathological analysis and training were highly effective for these patients with DLI and phonological difficulties.
