Geriatric medicine and rehabilitation medicine have similar points of view. They have common concept for stages as disease (disorder), impairment, disability, and handicap. WHO has announced International Classification of Functioning, Disability and Health (ICF). Comprehensive Geriatric Assessment (CGA) is useful for evaluation of geriatric syndrome, such as frailty, sarcopenia, and cognitive impairment. Frailty seems to be found approximately 10-14% for more than 65 years. Sarcopenia implies a situation that physical function is reduced by muscle loss. It can be diagnosed by the Asian Working Group for sarcopenia (AWGS) or the European Working Group on Sarcopenia in Older People (EWGSOP2) criteria.
