A new study finds decreased handgrip strength in the elderly is associated with increased risk of death.
Researchers found that a weaker grip at 85 and 89 years, and less strength overall , was a sign of increasing physical trouble.
The reason for the link is not clear. But, doctors can identify elderly people at risk with a simple device called a handgrip dynamometer, although they are not commonly found in offices.
There's more on this study in the Canadian Medical Association Journal.
