Balance in children following cochlear implantation

Area of Science:

• Audiology
• Neuroscience
• Pediatrics

Background:

• Vestibular function is crucial for balance and spatial orientation.
• Cochlear implantation is a common treatment for severe to profound hearing loss in children.
• The impact of cochlear implants on vestibular function in pediatric populations requires further investigation.

Purpose of the Study:

• To evaluate and compare vestibular function in children with unilateral and bilateral cochlear implants against a control group of healthy, non-implanted children.

Main Methods:

• An observational case-control study was conducted involving 30 children (10 per group).
• Posturography, utilizing a Wii Balance Board and Vestio App, assessed balance and sensory interaction.
• Root mean square calculations quantified postural sway for each participant.

Main Results:

• A significant difference in vestibular function was observed between implanted and non-implanted children (P < 0.05).
• All children, particularly those with eyes closed on compliant surfaces, exhibited greater postural instability (P < 0.05).
• Testing completion rates were lower for implanted children: 30% for bilateral and 10% for unilateral implants.

Conclusions:

• Posturography is a cost-effective and user-friendly method for assessing pediatric vestibular function.
• The study confirmed significant differences in vestibular function between cochlear implant recipients and controls.
• Future research will involve interval post-operative testing to precisely determine the effects of cochlear implantation on vestibular function.
