The objective of the study was to determine if a test battery consisting of electrocochleography and rotary chair testing would differentially diagnose between Meniere's disease and migraine-associated dizziness. A retrospective chart review of 10 patients diagnosed with Meniere's disease and 10 patients diagnosed with migraine-associated dizziness was completed. Comparisons between these two groups were made to determine if statistically significant differences existed in terms of their: 1.) mean rotary chair gain values; and 2.) ECochG SP/AP amplitude ratios. Results indicated that no statistically significant differences existed between the ECochG SP/AP amplitude ratios of these two groups. Statistically significant differences between these two groups did however exist in the rotary chair gain values at all of the test speeds with the exception of 0.32 Hz. The results suggest that rotary chair gain values have the ability to differentially diagnose between Meniere's disease and migraine-associated dizziness.
