Guralnik et al used a battery of 3 tests to evaluate lower extremity function. This correlates with disability, especially in the elderly. The authors are from NIH, CDC, multiple universities in the US, and Hospital I Fraticini in Florence, Italy.
Parameters:
(1) standing balance
(2) walking test
(3) rising from a chair test
Standing positions:
(1) full tandem - heel of one foot in front of the toes of the second foot
(2) semi tandem - heel of one foot held beside the great toe of other foot
(3) side by side

total score =
= SUM(points for all 3 measures)
Interpretation:
• minimum score: 0
• maximum score: 12
• The higher the score the more likely that an elderly person will be without disability at 4 years.
