The daily number of falls is increasing with increasing age and due to balance influencing impairments. In order to reduce the related number of falls and fall-related deaths, mainly physical training interventions were investigated so far. In this proposed project, we plan to investigate a novel approach – the application of air-coupled ultrasound vibrations – to reduce the number of daily falls. Ultrasound allows a versatile choice of the signal shape, the amplitude, and the frequency as well as a contact-less coupling to the subject. The functional mechanism of the balance improving effect using vibratory stimuli is still unclear. However, it is assumed that vibration improves the sensory perception, the processing or the transfer of sensor signals.
