What Actually Prevents Falls

This is where the evidence is genuinely strong, and where a lot of familiar advice has it backwards.

Exercise, and a Specific Kind of It

A review of 108 trials covering 23,407 people found exercise reduces the rate of falls by 23%, with high certainty. Balance and functional training specifically: 24%. Combining balance work with strength training: 34%. Tai chi: 19%, with weaker certainty (Cochrane, 2019). The US Preventive Services Task Force gives exercise a Grade B for people at increased risk (2024).

Walking on its own is not what was tested. It is balance and leg strength. That distinction is the single most useful thing on this page.

Home Changes, Mainly for People Already at High Risk

A 2023 review found that reducing hazards in the home cut the fall rate by 38% for people at high risk, with high certainty. For an unselected general population, it did nothing measurable (Cochrane, 2023). A large UK trial of a single occupational therapist home visit found no benefit at all (OTIS, 2021).

The lesson is not to skip it. It is that a walkthrough with a list of recommendations is not the intervention. Actually making the changes is, and mainly for someone who has already fallen, come home from a hospital stay, or needs daily support.

Roughly in the order the mechanism data supports:

1. Clear the walking paths. Throw rugs, cords, clutter, pet items.
2. Light the path from bed to bathroom. Night lights, and switches at both the top and the bottom of stairs.
3. Bathroom. Grab bars next to and inside the tub, and next to the toilet. A towel bar is not a grab bar and will not hold a person.
4. Stairs. Handrails on both sides, running the full length. Nothing stored on the steps.
5. Everyday items at waist height, and a step stool with a handhold rather than a chair.
6. Thresholds, and anywhere the flooring changes.

The CDC’s Check for Safety checklist is free, printable, and goes room by room. There is also a CDC brochure written for family caregivers specifically.

Medications

A complete list at every appointment, including over-the-counter drugs and supplements, is what makes a real review possible. The classes associated with higher fall risk include benzodiazepines, opioids, sedatives and sleep aids, antidepressants, antipsychotics, anticonvulsants, muscle relaxants, blood pressure medications, anticholinergics, and antihistamines, including the over-the-counter ones nobody thinks of as risky (NCOA, citing CDC).

Vitamin D, Which Is Where Most of Us Were Wrong

The US Preventive Services Task Force recommends against vitamin D supplementation to prevent falls in older adults living at home. That was a Grade D recommendation in 2018, and a 2024 draft update reaffirms it.

This is narrow and worth reading precisely. It is about supplementing in order to prevent falls. It is not about treating a diagnosed deficiency or managing osteoporosis, which are different questions and belong with a doctor.

Vision Is Weaker Than Expected

The same 2023 Cochrane review found vision-correcting interventions made little or no difference to fall rates. An annual eye exam is still sensible, and a first pair of multifocals has a known adjustment period, but it does not count as prevention.

Programs You Can Enroll Someone In

These run through Area Agencies on Aging, senior centers, health systems, and YMCAs. None publishes a price, because the local host sets it, and they are frequently free or subsidized through federal falls-prevention funding. The Eldercare Locator, 1-800-677-1116, is the way to find them.

A Matter of Balance is eight two-hour classes, built specifically around fear of falling. Available in seven languages beyond English, plus large print and Braille. This is the one for someone who has stopped leaving the house.

Otago is seventeen strength and balance exercises plus walking, three times a week, assessed by a physical therapist. NCOA reports a 35 to 40% reduction in falls, which is the program’s own figure rather than a pooled review. Because it is PT-delivered it is often billable to Medicare Part B. This is the one for someone frail or who has already fallen.

Tai Chi for Arthritis and Fall Prevention is suited to joint pain and arthritis, and can be done by videoconference.

Stepping On is seven weeks, with a reported 31% reduction in falls from its original trial. Worth knowing the eligibility before you go looking: participants must live independently, not use a walker indoors, not use a wheelchair, and have no diagnosed cognitive impairment. That rules out a fair number of the people in our households, and we would rather say so here than have anyone find out on the phone.

There is also a free Falls Free CheckUp, thirteen questions, and it can be completed on someone else’s behalf.
