The purpose is to test the balance of children with unilateral,bilateral cochlear implants
and patients having unilateral implants before,bilateral implants after surgery,using the
Bruininks-Oseretsky Test 2nd ed. to find out if the cochlear implants have an effect.
Hearing impairment has a significant impact on individual quality of life and stresses
community resources. In the last two decades cochlear implantation has developed into the
new standard of care for severe to profound haring loss. Recent studies have shown bilateral
implantation improves sound localization and understanding of speech in noise. For
children, this is seen as a significant benefit. As we begin to offer bilateral cochlear
implants to a growing number of children it would be in our patient's best interest to
evaluate whether or not this may cause balance impairment. We will evaluate the balance
scores of children with bilateral cochlear implants, and compare their results to
unilaterally implanted children and a hearing impaired population, with the
Bruininks-Oseretsky Test 2nd ed (BOT2). In addition we will take a small group of
unilaterally implanted patients and test them before and after a contralateral cochlear
implant as a prospective study group.
- Children with cochlear implant(s) activated for at least two weeks before
- Children with severe to profound deafness that have not received intervention.
- Children with mental retardation, associated physical handicaps, or chronic sedative
use prohibiting completion of the balance tests.
