Postural Stability Romberg's Test in 3D Using an Inertial Sensor in Healthy Adults

Inertial sensors are commonly used to study balance while standing upright. Researchers employ various configurations of sensors and methods for recording and processing balance data. We propose a technical approach and a previously tested method of processing primary data, analyzing them along three mutually perpendicular planes.

The study involved 109 healthy adults, using a commercially available inertial sensor designed for medical purposes. This research establishes normative values for stabilometric measures, obtained from three oscillation planes with the sensor positioned on the sacrum. The vertical component of the oscillations is comparable to the frontal and sagittal components.

Normative data are crucial for clinical studies, serving as a baseline for evaluating patient results. This study provides normative parameters for a widely used Romberg's test, offering valuable data for both scientific and clinical research.
