Aging and motor adaptation: Increased movement variability, slowing rates of adaptation, and smaller aftereffects.
Abstract
Studies over the past 3 decades have shown decreased motor adaptation with age. The most widely supported theory for this change proposes that older adults fail to successfully implement cognitive strategies to facilitate performance. However, increased movement variability may also affect adaptation with age, but this has to date remained unstudied. Here, we examine whether age-related increases in movement variability influence adaptation. Healthy older adults (

Research summary
Increased movement variability in older adults negatively influences their motor adaptation. The study addresses age-related changes in motor function, which are crucial for understanding the mechanisms of aging and potential interventions to improve quality of life in older populations.
