Good evidence shows that exercise or physical therapy and vitamin D supplements can reduce falls in older adults, probably by improving muscle strength and balance. Prevention strategies that involve an in-depth assessment of multiple risk factors for falls and that address factors identified during the assessment may provide a small benefit. Although it is possible that some combination of interventions in selected patients could provide important benefits, available studies do not define what such a combination or population would be. Studies are not available to determine whether the following interventions by themselves are effective in reducing falls in older adults: vision correction, medication discontinuation, protein supplements, education or counseling, and home hazard modification.
