Galvanic vestibular stimulation (GVS) is a technique that has been used for a clinical measure. GVS is performed by passing small currents through the vestibular labyrinth, using surface electrodes. To measure the effect on the vestibular system, one may record either eye movements or postural movements (which can be controlled with the help of a computer based Matlab simulink program). Typical stimulus configurations include placing an electrode on each mastoid, one positive and one negative, to produce medial / lateral sway or horizontal / vertical eye movements. The ability of this technique in reducing the neglected region of the patient suffering from the ‘Neglect syndrome’ is an important issue in therapeutic neurological research. In the Institute of Medicine (Research Centre Juelich), novel GVS-based stimulation techniques for the therapeutic treatment of the so called ‘Neglect syndrome’ are under development. There are how ever only a few systems for Vestibular Galvanic Stimulation available in the market. These systems for GVS are much restricted with their stimulation parameters such as the frequency ranges and stimulation patterns. So we at Central Institute for Electronic, Research Centre Juelich, developed a dual channel GVS unit both in positive and negative directions independently, therefore enabling independent current stimuli in the frequency range from 0 to 10 KHz, voltage range from 0v to ±35 V, current range from 0 to ±7.5 mA timer up to 2 hours for the safety of the patient. The purpose of this designed GVS device is to optimize GVS stimulation pattern for reducing the neglected region in Neglect Syndrome patients and can is aimed to be used for research purposes. |
