The effects of age at cochlear implantation on balance in children: A pilot study

Abstract

Aim: The evaluation of the effects of age at cochlear implantation on balance in children. Research design: Cross-sectional study. Study sample: Twenty children who received their cochlear implants (CI) before the chronologic age of 48 months (Early CI Group), and 20 children who received their CI at 48 months chronologic age or later (Late CI Group). Intervention: All children underwent Tandem Romberg (TR) test, Single-Leg stance (SLS) test, Pediatric Clinical Test of Sensory Interaction for Balance (P-CTSIB), Pediatric Balance scale (PBS) and Timed Up and Go (TUG) test. Data collection and analysis: The scores of TR, SLS and P-CTSIB and TUG tests and PBS were recorded. Mann Whitney U test and Independent-samples t-test were used to compare data between groups. Results: TR (eyes opened-EO), SLS (EO), PBS, and TUG scores and incidence in dizziness symptoms did not show significant differences between the groups ( p > 0.05). Duration of TR and SLS tests (eyes closed-EC), P-CTSIB-positions 5, and 6 were significantly longer in the Early CI Group than the Late implanted group( p < 0.05). Conclusion: Although the age of cochlear implantation did not affect functional balance for children, it has been found to cause impaired balance performance in difficult static conditions and increased frequency of dizziness.
