Imbalance is a risk of cochlear implantation. This is particularly important in patients receiving bilateral implants, who are often children. 25 adult and pediatric patients undergoing cochlear implantation were tested pre-operatively and post-operatively using tests of balance function. Results showed moderate losses in some test paradigms following implantation in the patient group as a whole. While changes in balance function due to cochlear implantation are not uncommon, their practical effect on function may be minor.

Experiments explored the minimal kanamycin dosing regimen that renders protection against noise induced hearing loss in young CBA/J mice. We also tested the age-dependence of protection in CBA/J as well as the dependence of protection on a particular genetic background in experiments using young C57BL/6J and CBA/CaJ mice.

Experiments evaluated both noise vulnerability and the extent of protection from noise by sub-chronic low-dose kanamycin in young F1 hybrids resulting from a cross between C57BL/6J and CBA/J inbred mice.

Experiments evaluated cochlear expression of key stress proteins in kanamycin and saline treated C57BL/6J and CBA/J mice using immunocytochemistry. A qualitative approach was used to assess immunoreactivity for HSP70, HSF-1, HO-1, and TNF-α as a function of strain and treatment.

Spontaneous writing samples of deaf children with cochlear implants were analyzed for syntactic errors and other descriptive characteristics. These results were compared to a small sample of writings from hearing children.
