Falls and Frailty

In older adults a fall is usually the visible result of several treatable contributors acting together: muscle weakness, impaired balance, reduced vision, medication side effects, foot problems, low blood pressure on standing, and hazards at home.

Treating a fall as bad luck means none of these are addressed and the next fall follows. Assessment identifies which of them apply to this person and in what proportion.

After a fall, many people reduce activity to avoid another one. Reduced activity weakens muscle and degrades balance, which raises the risk of the next fall. Fear itself also alters walking — shorter steps, less confident weight transfer — in ways that make falling more likely.

So confidence is treated as a target alongside strength. A programme that improves leg strength but leaves someone afraid to leave the house has not reduced their risk.

Strength and balance testing, gait analysis, standing blood pressure, vision, footwear, cognition where relevant, and a full medication review — because certain drug groups substantially increase falls risk and their contribution is frequently overlooked.

Home hazards are reviewed too — lighting, loose rugs, bathroom grab rails and stair handrails. Reducing such hazards probably lowers the rate of falls by about a quarter overall, and by more than a third in people at higher risk, such as those who have already fallen; in people not selected for risk it has shown no effect 3.

Progressive strength and balance training at sufficient intensity and sustained over time. This is the intervention with the strongest evidence: programmes built on balance and functional exercise reduce the rate of falls by about a quarter, and those that add resistance training probably by about a third 1. What matters is that balance is genuinely challenged — Tai Chi may also reduce falls, while the effect of walking or resistance training on their own is uncertain 1.

Programmes that add medication review, home changes and other measures tailored to each person's risks may slightly reduce the rate of falls compared with usual care, but that evidence is of low certainty and it is unclear whether they add to exercise alone 5. We set the programme at a level that is genuinely demanding, supervised, and continued rather than delivered as a short block.

Frailty is a measurable state — slow walking, weak grip, exhaustion, low activity, unintentional weight loss — rather than a synonym for old age. It predicts falls, hospitalisation, loss of mobility and independence, and death 6.

It is also reversible in its earlier stages, which is the part most people are not told. In a trial in frail nursing-home residents with an average age of 87, progressive resistance training increased strength and walking speed, while a nutritional supplement without exercise had no effect 2.

The World Falls Guidelines recommend balance-challenging and functional exercises, such as rising from a chair and stepping, three or more times a week, tailored to the person and progressed in intensity for at least 12 weeks, and continued longer for a greater effect 4. Tai Chi or additional progressive strength training can be added where feasible 4.

For someone who travels for an intensive block, this is the practical point: supervised sessions set the right level and teach the exercises, but the benefit depends on continuing them at home, several times a week, long after the block ends 4.
