A new study published in the Archives of Gerontology and Geriatrics indicates that the increased prevalence of falls and other injuries in seniors may often be attributed to a decline in ability to mentally estimate and anticipate stepping and reaching distances.
The research conducted by a Texas A&M University studied the ability to mentally represent an action before attempting it. This visualization, researchers explained, is something all people naturally do before attempting any action. Before reaching for a cup, for example, you brain visualizes grabbing the cup and estimates whether the object is within or outside your reach.
The study indicates that in people 65 and older, this ability to accurately mentally visualize an action before attempting it is much weaker than those under the age of 65. Underestimating or overestimating the distance of objects has serious consequences, including trips and falls.
Researchers indicate that this knowledge could lead to developing techniques that reduce falls and other injuries. Activities such as imagery interventions and other activities geared towards improving specific cognitive ability may be able to train elderly people to recognize and adapt to this decline in their motor imagery ability.
