- •Head-turn gait speed is affected to a greater extent than self-selected gait speed in older individuals with diminished lateral balance stability and at greater risk of falls.
- •The balance tolerance limit has the potential to be a marker of balance ability in older individuals.
- •Prospective studies are need to examine whether head-turn gait speed can differentiate future fallers from nonfallers.
Main Outcome Measures
