How physiotherapy prevents injuries and falls

Prevention rarely makes headlines. A fall that never happens, a knee ligament that never tears — these are non-events, and non-events are easy to take for granted. Yet the evidence that the right kind of exercise can stop injuries before they start is now some of the strongest in all of rehabilitation science. It spans two very different groups: older adults at risk of falling, and younger athletes at risk of tearing something on the pitch. In both, structured, progressive movement does measurable work.

This article is general education, not a prescription. It describes what well-designed studies have found about categories of exercise programme — not a routine for you to follow on your own. The value of these programmes lies in how well they fit the individual, which is exactly why a tailored assessment matters.

Falls in older adults: a big problem with a good answer

Falls are the leading cause of injury in older people. Around 30% of adults over 65 fall at least once a year, and falls are a major driver of fractures, hospital admissions, loss of independence and — through fear of falling again — a downward spiral of inactivity. [2][3] The reassuring news is that falls are not an inevitable part of ageing. They are, to a substantial degree, preventable.

The landmark evidence here is a 2019 Cochrane systematic review by Sherrington and colleagues, which pooled 81 randomised trials involving nearly 20,000 community-dwelling older adults. Cochrane reviews sit at the top of the evidence hierarchy, and this one rated its main finding as high-certainty. Exercise, taken as a whole, reduced the rate of falls by about 23% compared with no exercise or usual care. [1]

What counts as "exercise" matters. Not all movement is equal for this purpose. The review found the strongest signal for programmes centred on balance and functional tasks — think controlled standing, stepping and sit-to-stand movements that challenge stability in the ways daily life does. These reduced falls by roughly 24%. Programmes combining several exercise types also worked well, and Tai Chi — a gentle, flowing practice that trains weight-shifting and balance — reduced the number of people who fell by about 20%. [1] Walking alone, or general activity without a balance component, showed weaker effects.

These findings have been written into guidance. The 2022 World guidelines for falls prevention and management — a global consensus published in Age and Ageing — give a strong recommendation for exercise programmes that include balance-challenging and functional exercises, delivered three or more times a week, individualised, progressed in intensity over at least 12 weeks and continued longer for greater effect. [3] The World Health Organization's 2020 physical activity guidelines echo this: older adults should do varied multicomponent activity emphasising functional balance and strength training on three or more days a week, specifically to help prevent falls. [4]

Two words in that guidance do a lot of work: individualised and progressed. A programme has to start at the right level for the person in front of you and get harder as they get stronger — too easy and it does nothing, too hard and it becomes a hazard in itself. Judging that balance, and adjusting it over weeks, is the core of what a physiotherapist does in a falls-prevention assessment. It is also why "just do some balance exercises from a video" is a weaker strategy than a supervised, tailored plan.

Why balance and strength training works

Staying upright is not a single skill but a system. It depends on muscle strength (especially in the legs), on quick reflexive responses when you are nudged off balance, on the sensors in your joints and inner ear, and on the confidence to move without freezing. Ageing, inactivity and some medications chip away at each of these. Balance and functional training targets them directly: it rebuilds the strength to recover a stumble, and it rehearses the reactions the body needs when a kerb or a rug appears unexpectedly. Because the training is specific to the demands of standing and moving, the gains transfer to real life in a way that generic fitness does not always achieve.

Consistency is decisive. The guideline emphasis on "at least 12 weeks and continued longer" reflects a simple reality: the protective effect fades if training stops. Fall prevention is less a course of treatment than a habit to be maintained — which, again, is easier to sustain with professional support and periodic reassessment than alone.

Preventing sports injuries in younger athletes

At the other end of the age range, the same principle — train the movement, prevent the injury — shows up in sport. The best-known example is the FIFA 11+, a structured warm-up developed with sports-medicine researchers that combines running drills, strength, plyometrics (jumping and landing) and balance work into roughly 20 minutes before training. It is designed to be done regularly, not as a one-off.

The evidence for it is robust. A 2017 systematic review and meta-analysis by Thorborg and colleagues, restricted to randomised controlled trials, found that FIFA's exercise-based programmes reduced the overall rate of football injuries by around 39%. [5] A frequently cited landmark trial — a cluster-randomised study of 1,892 young female footballers published in the BMJ in 2008 — found the warm-up cut overall injuries by about a third, with even larger reductions in overuse injuries (around 53%) and severe injuries (around 45%). [6] These are the kinds of effect sizes that would make a drug a blockbuster; here they come from a warm-up.

The ACL story: halving a career-threatening injury

Nowhere is the case clearer than for the anterior cruciate ligament (ACL), the knee ligament whose rupture can end a season and sometimes a sporting career. Most ACL injuries are non-contact — they happen during landing, cutting or decelerating, when the knee is loaded in a vulnerable position. That is precisely what makes them trainable: teach the body to land and change direction with better control, and you remove much of the risk.

A 2018 "meta-analysis of meta-analyses" by Webster and Hewett synthesised the accumulated evidence and found that ACL-injury-prevention training programmes reduced the risk of all ACL injuries by about 50% across athletes, and reduced non-contact ACL injuries in female athletes — who carry a higher baseline risk — by about 67%. [7] In other words, a well-run neuromuscular programme can roughly halve overall ACL risk and cut the most preventable injuries in the highest-risk group by two-thirds.

One caveat runs through all of this: the programmes only work if they are actually done, and done properly. Across the sports-injury literature, teams and individuals who stick with the programme get more protection than those who do it occasionally or drift from the correct technique. Getting the movement patterns right — and keeping them right — is where coaching and physiotherapy input earns its keep.

What this means for you

The through-line is consistent across the age spectrum: targeted, progressive, well-executed exercise measurably lowers the risk of falls and injuries. But the same evidence that makes the case also comes with a condition attached — the benefit depends on the programme being matched to the person's starting point, risk profile and goals, and then adjusted over time. A balance programme pitched at the wrong level, or a warm-up done with sloppy landing mechanics, gives away much of the advantage.

That is the practical reason to involve a qualified physiotherapist rather than self-prescribing from the internet. An assessment can identify your specific risk factors — leg weakness, poor balance, previous injuries, movement patterns that load a joint the wrong way — and build a plan around them, then progress it safely. If you are an older adult concerned about falls, or an athlete wanting to reduce injury risk, a tailored programme designed with a professional is the way to turn this strong evidence into your own non-event.
