Falls and Balance After Stroke: The Risk and the Honest Evidence on Prevention

Falls are one of the most common problems after a stroke, with a risk as high as 73% in the first year after a severe stroke, yet exercise has not been proven to reliably prevent falls specifically after stroke. Balance can and does improve with practice, but the honest evidence is that better balance in the clinic has not been shown to translate into fewer falls at home¹².

I want to be straight about this one from the start, because it is the article where the reassuring version and the true version part company. I fell more times in my first year than I can count. Some were undignified, one cracked a rib, and most happened doing something ordinary that I had done ten thousand times before the stroke. When I asked what would stop it, I expected a clean answer. There isn’t one. What there is instead is a realistic picture, and that turns out to be more useful. This sits under the wider story of neuro-rehabilitation, and it leans on the honest evidence about staying motivated in long-term rehab.

How common are falls after a stroke?

Falls are one of the most common complications of stroke, with a risk as high as 73% in the first year after a severe stroke. They happen in hospital and, just as often, after people get home and start attempting real life again¹.

The reasons stack up rather than stand alone. There is weakness down one side, altered sensation and balance, spasticity pulling a limb out of position, and often visual or attention problems that mean you do not fully register the edge of a step or a bag on the floor. Add post-stroke fatigue, which affects around 50% of survivors, and you have someone attempting difficult movements while depleted. That combination, not clumsiness, is why the numbers are so high.

Does exercise prevent falls after a stroke?

No: exercise has not been proven to reliably prevent falls specifically after stroke. A Cochrane review of interventions for preventing falls after stroke found the evidence too weak and inconsistent to conclude that exercise, or any single intervention, reduces the number of fallers or the rate of falls in this group².

This surprises people, because in the general older population exercise does reduce falls, and because balance training clearly improves balance scores after stroke. Both of those are true. The gap is that improving a balance measure has not been shown to carry through to fewer actual falls at home. The Royal College of Physicians is careful here, and so am I: this is a place where confident guideline-style advice runs slightly ahead of the hard evidence, and pretending otherwise would be dishonest¹. It belongs in the same honest category as robotics in neuro-rehabilitation, where recommendation and proof do not fully line up.

So why keep working on balance at all?

Because balance, strength, and walking are worth improving in their own right, and task-specific practice is how the brain relearns them through neuroplasticity. The falls evidence being thin does not make the therapy pointless; it means we should not oversell one specific outcome³.

Better balance means more confidence, more independence, and a wider life, and those matter enormously whether or not a trial can prove they cut fall counts. The mechanism is the same one that drives all recovery: intensive, repetitive, meaningful practice, explained in how neuroplasticity drives recovery. In practice balance work sits inside physiotherapy after stroke and the gait work described in gait and treadmill training. I did the practice. My balance genuinely improved. I also still fell. Both things were true at once, and holding them together is the honest position.

Walking, community walking, and where falls happen

Most people do walk again, but not to the same level everywhere: about 75% walk independently by 3 months and up to about 85% achieve basic independent walking by 6 months, while fewer than 50% reach community-level walking. Community-level means crossing roads, covering distance, and coping with speed and uneven ground³.

That gap is exactly where a lot of my falls lived. Walking across a flat, familiar room was fine within months. A wet pavement, a kerb I misjudged, a shopping bag changing my centre of gravity, that was another matter entirely. The full picture is in will I walk again after a stroke, and it is worth reading precisely because independent walking indoors and safe walking in the world are two different milestones.

What actually reduces falls, if not exercise alone

The most useful measures are usually practical and specific: treating the weak-side problems, managing fatigue, checking vision and medication, and adapting the home, rather than a single exercise that abolishes falls. A team works out the particular reasons you are at risk instead of prescribing one blanket answer⁴.

For me the changes that helped were unglamorous. Pacing so I was not attempting stairs when exhausted. Getting my shoulder pain after stroke and spasticity looked at, because pain and a badly positioned limb throw off everything else. Grab rails where they mattered. NICE frames this as an individualised assessment rather than a leaflet, and that matches what worked⁴. This is where occupational therapy after stroke earns its place, and where sensible goal-setting in rehabilitation keeps the aims realistic.

How balance is measured, and why fear counts

Clinicians track balance with standardised scales rather than a hunch, and they take fear of falling as seriously as falls themselves. The Berg Balance Scale scores 14 tasks and is widely used after stroke, alongside daily-activity measures like the Barthel Index (0 to 100)⁵.

The measurement matters because it separates real change from wishful thinking; you can see whether balance is genuinely improving, tracked the way all progress should be in measuring progress in rehabilitation. But there is a human factor the scales only partly capture. After my rib, I stopped doing things I could actually do, because I was frightened. Fear of falling can shrink your world as much as a fall does, and it feeds the low mood covered in post-stroke depression. Naming it to my team, rather than quietly narrowing my life, was one of the more useful things I did. If you take one thing from this piece, let it be that the honest answer is not defeatist: balance is worth training, falls are worth guarding against sensibly, and you are allowed to be told the truth about what the evidence can and cannot promise.
