Balance problems make it difficult for people to maintain stable and upright positions when standing, walking, and even sitting. Older people are at a higher risk of having balance problems; 75% of Americans older than 70 years are diagnosed as having “abnormal” balance. Older women are more likely than older men to develop balance problems, although the difference between the genders is small. Balance problems increase by almost 30% in people aged 80 years or more. Physical therapists develop individualized physical activity plans to help improve the strength, stability, and mobility of people with balance problems.
