Sažetak
Deep sense capability is one of very important indicators of numerous pathologies in medicine, and one of the indicators of deep sense is the sense of vibration. One of the methods for testing the sense of vibration is vibratory evoked potentials, which present the response of the nervous system to vibratory stimulus. Currently used vibratory stimulation has small clinical value because obtained results do not incorporate quantifiable information about entire afferent activity of vibratory sensory pathway (VSP), and response appears around 50 ms, providing no information about early cortical activity. The aim of this research was to develop a method of vibratory stimulation that would provide information about the functional integrity of the whole VSP. The impossibility of monitoring the function of the whole VSP is related to changes in stimulation parameters between successive stimuli and because of that the basic premise of evoked potentials (equal parameters for every stimulus) is disrupted. Vibratory stimulator with controllable pressure of vibratory applicator was constructed in order to provide equal parameters for every stimulus to obtain quantifiable information about entire VSP. Optimum parameters of stimulation were chosen (stimulus frequency of 120 Hz, stimulus duration of 50 ms, and wrist as the site of stimulation).
