Characteristics of Sensory Processing in Children with Cochlear Implants and Hearing Aids

Sensory processing includes perception, organization, and reaction to sensory stimuli. Research has shown that deaf and hard-of-hearing children have unique sensory processing characteristics. The aim of this study was to identify these characteristics and examine the contributions of factors such as type of amplification, chronological age, hearing age, and frequency of rehabilitation to sensory processing features. Parents of 52 children, aged 3 to 10 years old, completed the Sensory Profile questionnaire. Results showed that most children were within the typical performance range in most subscales, however, children with cochlear implants had better scores in several domains compared to children with hearing aids. Chronological age, hearing age, and frequency of rehabilitation did not contribute to overall sensory processing. These results indicate that children with cochlear implants have a more successful integration of sensory processing abilities. Early intervention and consistent rehabilitation are needed to optimize sensory outcomes in deaf and hard-of-hearing children.
