Increased Gait Variability May Not Imply Impaired Stride-To-Stride Control of Walking in Healthy Older Adults

Highlights • In older adults, increased gait variability is associated with falls. • Need to differentiate effects of physiological noise from stepping control strategy. • High-functioning healthy older adults exhibited increased gait variability. • However, they exhibited no differences in how they...

Zusammenfassung:Highlights • In older adults, increased gait variability is associated with falls. • Need to differentiate effects of physiological noise from stepping control strategy. • High-functioning healthy older adults exhibited increased gait variability. • However, they exhibited no differences in how they regulated stride variables. • Computational model verified greater variability arose solely from increased noise.
