What the paper asked
In frail older adults — not healthy ones — what does exercise do about falls?
What was found
- Gait speed improved: 0.09 m/s (0.02 to 0.15).
- Timed Up and Go fell by 3.73 s (1.55 to 5.92), and five-times sit-to-stand by 2.66 s (1.14 to 4.19).
- ⚠️ But the certainty of evidence for all of these is "low to very low" — the paper's own words, not ours.
- Balance showed only a trend and did not reach significance (p = 0.06), with 99% heterogeneity.
What does not follow from it
- ⚠️ There was almost no data on falls themselves: only two studies reported falls incidence and one reported fear of falling. The phrase "prevent falls" is more than the data can carry.
- Heterogeneity was very high in most analyses (I² between 77% and 99%), meaning the results scatter widely between studies.
- All the measurements were short-term (12 weeks or less). It says nothing about whether the gains hold.
What it means for someone here
This sits beside the healthy-older-adults paper because together they give the whole picture: in healthy older people the evidence for fewer falls is clearer; in frail older people — the ones most at risk — what is shown is improved function rather than fewer falls, and even that at low certainty. For a clinic writing programmes: set the target on measured function and follow it, and do not promise that the falling stops.
