Falls and Balance in Older Adults
Falls are not an inevitable part of aging, and the evidence for preventing them is stronger than for almost anything else in rehabilitation. A 2019 Cochrane review of 108 studies and 23,407 participants found that balance and functional exercise reduces the rate of falls by 24% — high-certainty evidence — and that programs combining balance, functional, and resistance exercise reduce it by around 34%. Two details matter practically: the exercise has to challenge balance rather than simply involve movement, and the effect is greatest at more than three hours a week. Most falls have several contributing causes at once, which is why assessment looks at medication, vision, footwear, and the home as well as at strength.
Why falls happen
Rarely one thing. Usually several at once.
- Strength and balance — lower limb weakness and impaired balance are among the strongest risk factors.
- Medication. Several classes increase falls risk, including some affecting blood pressure, sleep, and mood. Taking four or more medications is itself associated with increased risk. A medication review is one of the highest-yield interventions available and is frequently not done.
- Vision — including the period after a change of glasses, and particularly with progressive lenses on stairs.
- Blood pressure dropping on standing — common, treatable, and frequently missed.
- Feet and footwear — pain, deformity, and unsuitable shoes. Slippers are a recurring culprit.
- The home — loose rugs, poor lighting, clutter, and the absence of a rail where one is needed.
- Sensation — reduced feeling in the feet degrades balance, particularly in the dark. → Peripheral neuropathy
- Dizziness and vestibular problems → Vestibular rehabilitation
- Fear of falling — which reduces activity, which reduces strength, which increases risk. A cycle worth naming and breaking.
What the evidence shows
This is the clearest evidence base in geriatric rehabilitation, and it's worth being specific about. A 2019 Cochrane systematic review of 108 studies and 23,407 community-dwelling older adults found, compared with control:
| Intervention | Reduction in fall rate | Certainty |
|---|---|---|
| Balance and functional exercise | 24% (RaR 0.76, 95% CI 0.70–0.81) | High |
| Multiple exercise types (balance, functional, resistance) | 34% (RaR 0.66, 95% CI 0.50–0.88) | Moderate |
| Tai Chi | 19% (RaR 0.81, 95% CI 0.67–0.99) | Low |
Sherrington C, Fairhall NJ, Wallbank GK, et al. Exercise for preventing falls in older people living in the community. Cochrane Database of Systematic Reviews. 2019;1(1):CD012424. doi:10.1002/14651858.CD012424.pub2 · PMID 31792067. 108 studies, 23,407 participants. Tai Chi also reduced the number of people who fall by 20% (RR 0.80, 95% CI 0.70–0.91), high-certainty evidence.
Three findings with direct practical consequences.
- It works whether or not you're considered high risk. Effects were similar in trials that selected for falls risk and those that didn't.
- Balance has to be challenged. An earlier meta-analysis of 88 trials found greater effects from programs that genuinely challenged balance — not simply programs involving movement. Walking alone has not been shown to reduce falls.
- Dose matters. More than three hours a week was associated with greater effect. Most community programs deliver considerably less, which is worth knowing when choosing one.
What a falls program involves
- Assessment first — strength, balance, gait, medication, vision, blood pressure lying and standing, footwear, and the home.
- Balance-challenging exercise — reducing the base of support, moving the center of mass, minimizing upper limb support. It should feel challenging; safe but not easy is the target.
- Strength work, particularly legs.
- Functional practice — sit to stand, stairs, turning, reaching, walking while doing something else.
- Ongoing, not a course. The benefit fades when the exercise stops. Programs lasting 12 to 24 months show sustained effect, and falls prevention is best understood as something maintained rather than completed.
Named programs with evidence
- Otago Exercise Program — home-based strength and balance, individually prescribed, with reductions in falls reported across trials.
- Tai Chi — group-based, well tolerated, with high-certainty evidence for reducing the number of people who fall.
- Multicomponent strength and balance programs — the broadest evidence base.
Ask what a program is based on. A structured, evidence-based program is meaningfully different from a general exercise class.
Fear of falling
Real, common, and independently associated with falling. The cycle: a fall or near-fall causes fear · fear reduces activity · reduced activity reduces strength and balance · which increases the risk of falling.
It responds to being addressed directly — graded exposure to the activities being avoided, building confidence alongside capability, and naming the cycle so it can be interrupted.
The home
- Lighting — particularly on stairs and the route to the bathroom at night
- Remove or secure loose rugs
- Rails on stairs, both sides where possible, and in the bathroom
- Clear the routes you walk most, especially at night
- Footwear indoors — supportive shoes rather than slippers or socks
- A phone or alert within reach from the floor
Goals worth setting
Get out of my armchair without pushing off · Walk to the mailbox and back · Get up from the floor unaided · Carry a cup of coffee across the room · Stop avoiding the stairs
Improve balance · Increase lower limb strength
Frequently asked questions
Are falls just part of getting older?
No. Falls are common with age but they're not inevitable, and the evidence for preventing them is strong. A 2019 Cochrane review found balance and functional exercise reduces the rate of falls by 24%, with high-certainty evidence.
What exercise prevents falls?
Exercise that genuinely challenges balance, ideally combined with leg strengthening. Walking alone has not been shown to reduce falls. Tai Chi and structured programs like Otago both have supporting evidence.
How much exercise do I need?
The evidence points to more than three hours a week for the greatest effect, continued ongoing rather than as a fixed course. Most community programs deliver less than this.
I've fallen once. Does that matter?
Yes. A fall is the strongest single predictor of a further fall, and it should trigger an assessment — of strength, balance, medication, vision, blood pressure, and the home.
Could my medication be causing falls?
Possibly. Several classes increase falls risk, and taking four or more medications is itself associated with higher risk. A medication review is one of the highest-yield things available and is often not done — ask for one.
I'm afraid of falling, so I do less. Is that sensible?
Understandable, and it usually backfires. Reduced activity reduces strength and balance, which increases risk. Fear of falling responds well to being addressed directly with graded, supported activity.
When should I see a doctor after a fall?
After any fall, and urgently for any head injury — especially if you take blood thinners — loss of consciousness, inability to bear weight, or a fall preceded by dizziness or blacking out.
