Abstract
In this paper, the development of a device for quantitative vibratory sensation tests in medical treatment or rehabilitation fields is proposed. Recently, it has been speculated that the number of patients who have sensation disorders will increase with the aging of Japanese population. A sensation test is one good way to diagnose or to confirm the progression of the disease. Our final goals are to establish technologies to generate stimuli for sensation tests, using not only vibratory, but also temperature, tactual and pressure sensation so as to develop a small, light device for quantitative sensation testing which combines these multiple technologies.
