要約(日本語): Prosthetic hands may gain sensory function through direct electrical stimulation of sensorynerves. In order to clarify how the frequency of vibration sensation can be controlled when electricallystimulating sensory nerves, the relationship was studied between the stimulation signal, whichis input intraneurally into a single (rapidly adapting) mechanoreceptor unit, and the subjective frequencyof the evoked sensations. The subjective frequencies of the evoked sensation were psychophysicallyquantified using an actual mechanical stimulus to administer a standard stimulus. The frequenciesof the evoked sensations were found to be lower than those of the electrical stimulation.
