Half of over-65s suffer from dizziness and problems with balance. But some tests to identify the causes of such problems are painful and can risk hearing damage. Now, researchers from Chalmers University of Technology, Sweden, have developed a new testing device using bone conduction technology, that offers significant advantages over the current tests.
Hearing and balance have something in common. For patients with dizziness, this relationship is used to diagnose issues with balance. Commonly, a ‘VEMP’ test (Vestibular Evoked Myogenic Potentials) needs to be performed. A VEMP test uses loud sounds to evoke a muscle reflex contraction in the neck and eye muscles, triggered by the vestibular system – the system responsible for our balance. The Chalmers researchers have now used bone conducted sounds to achieve better results.
