Fall prevention that works is mostly one thing: the right kind of exercise

Falls are not a minor indignity of ageing; they are the leading cause of injury-related death among older adults. In 2021, an estimated 38,742 deaths in the United States resulted from fall-related injuries, and in 2018 more than a quarter of community-dwelling adults 65 and older — 27.5% — reported at least one fall in the previous year, with 10.2% reporting a fall-related injury [s2]. Against that, the good news is unusually clean: the single intervention with the strongest evidence is exercise, and the evidence is rated high-certainty.

What the strongest evidence shows

A Cochrane review pooled 108 randomised trials with 23,407 participants across 25 countries — on average 76 years old, 77% women — to test whether exercise prevents falls in people living in the community [s1]. The result is one of the more definitive in geriatric medicine. Exercise reduced the rate of falls by 23% (rate ratio 0.77, 95% confidence interval 0.71 to 0.83), rated high-certainty evidence, and reduced the number of people experiencing one or more falls by 15% (risk ratio 0.85, 95% CI 0.81 to 0.89), also high-certainty [s1].

To make those percentages concrete, the review translated them: against an illustrative background of 850 falls per 1,000 people over a year, exercise corresponds to 195 fewer falls, and against 480 fallers per 1,000, about 72 fewer people falling [s1]. Exercise may also reduce fall-related fractures (risk ratio 0.73, 95% CI 0.56 to 0.95) and falls requiring medical attention (risk ratio 0.61, 95% CI 0.47 to 0.79), though those findings rest on fewer studies and are lower-certainty [s1].

Not just any exercise

The important detail is the kind of exercise. The trials that work are dominated by programmes targeting balance and functional ability — the capacity to move, turn, rise and steady oneself — often combined with muscle strengthening [s1]. This is not the same as going for walks or doing general aerobic activity; the specific ingredient is challenging and improving balance and gait. Notably, the review found the benefit held whether or not trials specifically selected people already at increased risk of falling [s1].

What the guideline concluded

The U.S. Preventive Services Task Force reviewed the same body of evidence in 2024 and reached a consistent conclusion. It found with moderate certainty that exercise interventions provide a moderate net benefit in preventing falls in older adults at increased risk, and it recommended them — a "B" recommendation, the Task Force's language for a service clinicians should offer [s2].

The Task Force was more reserved about the other main approach, multifactorial intervention — the individualised assessments that check medications, vision, home hazards, blood pressure and more, then tailor a plan. It judged the net benefit of routinely offering these to be small, and issued a "C" recommendation, meaning the decision should be individualised rather than applied to everyone at risk [s2]. That is not a verdict that assessing hazards is useless; it reflects that, across trials, the packaged multifactorial approach delivered less consistent benefit than exercise did.

The honest summary

For once, the best-supported answer is also the simplest. The intervention with high-certainty randomised evidence for preventing falls is structured exercise that trains balance, gait and strength, and both a large Cochrane review and the USPSTF converge on it [s1] [s2]. The more elaborate, individualised programmes have a place but a weaker and less consistent evidence base [s2]. What the strong evidence does not endorse is the array of gadgets and supplements marketed for "fall prevention" — the trials that moved the outcome were exercise trials.

This is informational, not medical advice, and the right kind and intensity of balance training depends on an individual's health and mobility, which is a conversation to have with a clinician or physiotherapist rather than a decision to make from an article.
