What is the single best predictor of falls in older adults?

• A. Balance
• B. Toe strength
• C. Vision
• D. Hearing

Answer: (B)

The key idea is how lower-extremity strength relates to fall risk, specifically how the toes contribute to keeping balance. Toe strength, especially toe flexor or toe-grip strength, reflects the body's ability to stabilize the foot and generate corrective forces during standing and walking. When toe strength is weak, small perturbations are harder to counter, leading to greater sway and a higher chance of a misstep or fall. This link between toe strength and actual fall events makes it a particularly strong, if not the strongest, predictor among the given factors.

Balance matters, but it’s a broader measure of postural control, while toe strength directly underpins the mechanical support and rapid corrective actions the body relies on during everyday movement. Vision and hearing influence safety but don’t quantify the immediate physical capacity to respond to perturbations in the same way toe strength does. Because toe strength captures this specific, actionable aspect of balance and mobility, it stands out as the best predictor among the options.
