Abstract
There are various types of elderly in the community, ranging from healthy to frail and those who need nursing care. We have conducted researches on “gait,” “foot,” and “the elderly” in the community from the viewpoint of medical engineering and medical information. I have found that foot care is important for the continuation of positive activities. We would like to utilize this research to improve the effectiveness of rehabilitation of paralyzed patients with sequelae of cerebrovascular diseases.
