MedicalResearch.com Interview with: Daniel M. Merfeld, Ph.D. Professor of Otolaryngology Harvard Medical School Massachusetts Eye and Ear Director, Jenks Vestibular Physiology Laboratory Senior Scientist MedicalResearch.com: What is the background for this study? Response: Nearly half of the population will see a clinician at some point in their lives with symptoms related to the vestibular system (e.g., dizziness, vertigo, imbalance and blurred vision). The vestibular system, made up of tiny fluid-filled membranes in the inner ear, is responsible for receiving information about motion, balance and spatial orientation. With the goal of determining whether age affected the function of the vestibular system, our research team administered balance and motion tests to 105 healthy people ranging from 18 to 80 years old and measured their vestibular thresholds (“threshold” refers to the smallest possible motion administered that the subject is able to perceive correctly).
