The effect of an external auditory stimulus on postural stability of participants with cochlear implants

Postural control was evaluated in cochlear implant participants with and without amplification under several auditory paradigms. Speed of sway was recorded in each condition by means of Computerized Dynamic Posturography. Results indicate that an external sound source significantly improves balance in patients with cochlear implants.

A literature review of three common balance tests: Electronystagmography, Rotary Chair Testing, and Computerized Dynamic Posturography

This paper discusses the rationale, clinical applications, advantages and disadvantages of three common balance function tests: Electronystagmography (ENG), Rotational Chair Testing (RCT), and Computerized Dynamic Posturography (CDP).

Balance function following cochlear implantation

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.
