Balance problems? Virtual reality to help in diagnosis

Scientists from the Silesian University of Technology together with physiotherapists are working on a VR-based method of quick detection of balance problems. In the future, the results of their work will help to accelerate detection of ENT diseases and nervous system disorders.

Traditionally, balance tests are based on measurements of the patient`s body`s behaviour on special platforms, on which patients usually stand for 30 seconds with eyes open or closed. The diagnosis is based on the analysis of measured values describing body movement, but it does not always give a full picture of what is happening with the patient`s balance organ.

Researchers from the Silesian University of Technology together with physiotherapists are working on a new, virtual reality-based method of quick detection of problems with balance.

"In our research, we use virtual reality to provoke certain behaviours of the patient in the so-called sensory stimulus conflict", says Prof. Jacek Jurkojć from the Faculty of Biomedical Engineering of the Silesian University of Technology.

"We introduce an inconsistency between the stimuli received by the patient`s various senses. In other words, thanks to the use of virtual reality, the patient sees something different than the body feels. Our tests allow to check how the patient reacts to such a discrepancy (...). The analysis shows to what extent we rely on what we feel, see or what is registered by the vestibular organ when maintaining balance, and determine whether the body makes additional movements, indicating balance disorder", the scientist adds.

The next stage of research will be using these tests in the diagnosis of balance disorders. "Together with physiotherapists, we are developing a methodology for diagnostic tests that will quickly detect balance disorders at their very early stages, when they are not detected with standard methods", says Prof. Jurkojć.

Such analyses will allow to quickly detect diseases, in which patients have problems with balance. These include ENT diseases, nervous system disorders (for example multiple sclerosis), or systemic diseases (such as hypertension).
