Sense of balance of patient in rehabilitation is investigated. Two types of measurement of sense of balance are conducted. One is measurement of body sway by using force-plate. The other is balance test by using seesaw-like board. It is found by comparing the results of patients in rehabilitation with those of normal subjects that body sway of patients is larger than that of normal subjects, and patients with asymmetrical disease have inclination in the sense of balance in seesaw board test. These characteristics may be used to measure progression of rehabilitation.
