Abstract

Dizziness and vertigo are among problems reported after the Cochlear Implant (Cl) surgical procedure. The electrodes insertion to the inner part of the cochlea may disturb the vestibular component, which may cause loss of balance or postural instability. The objective of the research is to compare postural stability through the measurement of Limit of Stability (LOS), Centre of Pressure (COP) and Sway Velocity (SV) between adult cochlear implants users and normal hearing subjects in ten sensorial test situations. Ten Cl subjects were recruited from the Universiti Kebangsaan Malaysia Cochlear Implant program and the National Cochlear Implant program under the Malaysian Ministry of Health. Another 10 aged matched controlled healthy individuals were also involved. All Cl subjects were monaural users with Cl experienced ranging between 9 months to 17 years, with no reported surgical complications. A cross-sectional study was done by measuring postural stability using the Balance Rehabilitation Unit (BRU™) posturography. There was no significant difference (p = 0.436) between the LOS for the Cl group (mean = 158.45±47.83) cm2 and the control group (mean = 174.11 ±39.80) cm2. There was no significant differences between the COP values for both groups in all test situations except for a task (where subjects only received sensoiy inputs from vestibular system and not the visual and somatosensory); (p = 0.010). The sway velocity mean value for the Cl group was not significantly different than those in the control group (p>0.05) in all situations tested. Based on sensoiy analysis, the SV and COP values in the vestibular component of the Cl group differed than the control group despite not being statistically different. From this study we found that there was no evidence of posture instability in our Cl group as compared to the control group except for the COP value. We proposed that the COP measurement which involved all the sensory measures are sensitive in measuring the posture stability.
