The Claim
In healthy older adults with a mean age of approximately 72 years, there is no statistically significant difference in isometric knee extensor or flexor strength between individuals with a history of one or more falls in the past year and those without such a history, suggesting that these strength measures do not effectively differentiate fall history in this population.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Older adults around age 72 who have fallen before aren't any weaker in their knee muscles than those who haven't fallen — so knee strength might not help predict who's more likely to fall.
See the scientific wording
In healthy older adults aged approximately 72 years, there is no significant difference in isometric knee extensor (p = 0.729) or flexor (p = 0.157) strength between those who experienced one or more falls in the past year and those who did not, indicating that these strength measures may not distinguish fall history in this population.
What the research says
1 studyStudy: Muscle power is more important than strength in preventing falls in community-dwelling older adults.
The study found that older adults who fell were just as strong in their knee muscles as those who didn’t fall, which supports the idea that simple strength isn’t enough to predict falls.
