Control of electrical offset volage in Functional Electrical Stimulation system

摘要

An electric stimulation system using an electrode body includes an electrode body for applying a stimulation current to a conductive medium, a stimulation current generating unit for generating the stimulation current by using an input pulse and inputting the stimulation current to the electrode body, And a sample and hold unit for classifying and outputting an electrode offset voltage at a voltage, wherein the sample and hold unit samples an electrode voltage value output at the time of application of the input pulse when the input pulse is applied, The voltage value is fixedly output as the electrode offset voltage value in the stimulation period.
