The elderly experience a constant decline both physically and psychologically. Physical changes occur because of morphological changes in older muscles as you get older. Such physical changes cause slowing in motion, short steps, and muscle strength to drop and tend to wobble, resulting in slow aging in anticipation of the slipping, the tripping, the balance. Contributing factors include age, gender, body mass index (BMI) and physical activity. The purpose of this study is to identify factors related to the balance of the elderly in the house of tresna werdha inakaka, the city of ambon. This method of research is a descriptive description of a sectional cross. The sample sampling technique uses an purposive sampling of 49 respondents, with inclusions criteria: older people who can carry out their own activities and be willing to become the responders.
