Impact of Vestibular Function on Deaf Infants' Activities of Daily Living

This non-interventional study aims to assess the impact of vestibular impairments on the daily life activities of deaf children aged 0 to 2 years old. Three groups of participants will be included: deaf children with vestibular impairment, deaf children without vestibular impairment, and hearing children without vestibular dysfunction (control group). Children's daily activities will be evaluated through the OT Hope 0-5 years tool, a parent-administered questionnaire designed to measure competencies in different areas: personal care, play, and social interactions. This study also includes qualitative interviews with parents to further explore how vestibular impairments affect children's daily routines. It is hypothesized that: * Deaf children with vestibular impairments will show lower scores in daily life activities compared to the other two groups. * Deaf children without vestibular impairments will demonstrate scores closer to those of hearing children but may show some differences due to their hearing status. The research is conducted at the Robert Debré Hospital, in Paris, and aims to enroll 105 children over a three-year period. The data collected will provide insights into the specific needs of children with vestibular impairments and lay the groundwork for targeted early interventions.

Inclusion Criteria: * Group 1: Deaf children with confirmed vestibular impairment. * Group 2: Deaf children without vestibular impairment. * Group 3: Hearing children without vestibular impairment (control group). Exclusion Criteria: * Presence of neuromotor or orthopedic disorders. * Presence of pervasive developmental disorders that could interfere with daily activity assessments.
