Somatosensory Vibratory Evoked Potentials: Stimulation Parameters

In a clinical application, a method for an examination of a vibratory sense is not very objective and it depends on an active cooperation of a patient, which cannot be achieved in every situation. The aim of this research is to define parameters of an evoked potentials method with a vibratory stimulation technique which would establish reliable and repeatable results applicable in a clinical usage. During the research, different experimental conditions were performed (different methods of stimulation, different stimulation frequencies, different stimulus durations, different areas of stimulation). Presented results confirm the initial assumption that it is possible to detect reliable and repeatable cortical potentials evoked by the vibratory stimulation. Characteristic shapes and spatiotemporal distributions of evoked responses are established. Optimal stimulation parameters are defined as a prelude for a future research.
