The electrode setup for vibratory evoked potentials

Abstract

The difficulties related to the sense of vibration could be characteristics of the specific neurological disorders, so there is a need for measurable and quantifiable information about its functionality. Currently used methods for testing the sense of vibration do not provide appropriate information, and new method of vibratory stimulation was introduced in the area of the neurophysio- logical research. Method provides repeatable and quantifiable information about the evoked cortical activity, but there was a need for information about the functional integrity of the whole vibratory sensory pathways. The result of this research was the electrode setup that provides information from the Erb’s point through the levels of the cervical spine to the contralateral sensory area at the cortex. Also, the setup consists only of four electrodes for each side of the stimulation (six electrodes all together, because electrodes positioned on the cervical spinal cord are common for both sides of the body), which reduce time necessary for preparation and allows better use for clinical purposes.
