A falls programme designed by the community it served improved mobility; a social programme did not

Design

controlled pre-post study across community organisations, 12-month follow-up

Population

Aboriginal people aged 45 and over in New South Wales and Western Australia; exercise programme at 16 sites, social comparison programme at 3

Primary outcome

functional mobility on the Short Physical Performance Battery at 12 months

Effect

+0.8 points (95% CI 0.4-1.1) with faster stepping times and better leg stance; no change in falls, quality of life or psychological distress; comparison sites declined in mobility-related measures

Falls prevention programmes are among the best-evidenced interventions in geriatrics and among the worst-attended, and the gap is largest in communities whose priorities were not consulted in the design. Ironbark is an Aboriginal co-designed programme combining exercise with yarning circles - structured group conversation - delivered through organisations already serving Aboriginal people aged 45 and over in New South Wales and Western Australia. The comparison was against a social programme from the same family, 'Ironbark Healthy Community', with functional mobility at 12 months as the primary outcome.

The exercise programme ran at 16 sites and the social programme at 3, and recruitment fell short of target, so the two could not be analysed together - a real limitation that turns this into a controlled pre-post comparison rather than a trial. Participants in the exercise programme improved on the Short Physical Performance Battery by 0.8 points (95% CI 0.4-1.1), with faster stepping times, better single-leg stance and more incidental and planned exercise. Falls themselves, quality of life and psychological distress did not change. Participants at the social programme sites showed no change in functional mobility and declines in quality of life, physical activity and stepping time.

A 0.8-point gain on a 12-point battery is around the usual threshold for a meaningful change and is the kind of difference that separates independent from assisted mobility over time. Falls were not reduced, and with these numbers they could not have been. The transferable finding is about design rather than about exercise: programmes built with the community they serve, delivered through organisations people already attend, in a format that includes the social element people actually come for, get attended - and the comparison group here shows what happens to a population offered the sociable half alone.

• Deliver falls prevention through organisations older people already attend rather than through a new clinic-based service
• Co-design the format with the community, including the social element - attendance is the binding constraint, not efficacy
• Use the Short Physical Performance Battery to measure effect; it moved where self-reported measures did not
• Do not expect a fall rate reduction from a programme of this size - it was not powered for it
• Note the social-only comparison group declined on mobility and quality of life, so sociability alone is not the active ingredient

Why it matters

It shows the barrier to falls prevention is who designs and delivers it, not whether exercise works.

Don't overread it

A controlled pre-post study with unequal site numbers and under-recruitment - no randomised comparison was possible, and falls were unchanged.

The statistics, in plain English

A 0.8-point change on the Short Physical Performance Battery, with a confidence interval of 0.4 to 1.1, sits around the threshold usually taken as clinically meaningful on a 12-point scale. The design is the weakness: 16 intervention sites against 3 comparison sites, with recruitment below target and no combined analysis, makes this a controlled before-and-after study rather than a randomised comparison - so participants who chose or were offered the exercise programme may have differed at baseline. The null result on falls is uninformative at this sample size.
