A home workout plan for the oldest old — can it stave off frailty?
NCT ID NCT07731529
First seen Jul 28, 2026 · Last updated Sep 04, 2026 · Updated 3 times
Summary
This trial tests whether a personalized, home-based exercise program called Vivifrail can improve physical function, muscle health, and thinking skills in adults aged 90 and older. Participants are split into three groups: exercising twice a week, three times a week, or a control group. Researchers measure changes in balance, walking speed, and chair-stand ability over 12 and 24 weeks.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- a home-based multicomponent exercise program called Vivifrail, tailored to each person's abilities
- What this could lead to
- If it works, this could point toward a simple, home-based exercise plan to help the oldest adults stay mobile, strong, and sharp.
- What could go wrong
- This is a small, early-stage trial with only 54 participants, so results may not apply to everyone. The exercises require a caregiver's support, which may limit who can take part.
