Loss of cells from the motor system occurs during the normal aging process, leading to
reduction in the complement of motor neurons and muscle fibers. The latter age‐related …

Abstract Changes in old age that contribute to the complex issue of an increased metabolic
cost of walking (mass-specific energy cost per unit distance traveled) in older adults appear …

In a typical clinical gait analysis, the gait patterns of pathological individuals are commonly
compared with the typically faster, comfortable pace of healthy subjects. However, due to …

Drawing on the disciplines of neurophysiology and physics, Neuromechanics of Human
Movement, Fourth Edition, explores how the nervous system controls the actions of muscles …

A ubiquitous characteristic of elderly and patients with gait disabilities is that they walk
slower than healthy controls. Many clinicians assume these patients walk slower to improve …

Muscles operate eccentrically to either dissipate energy for decelerating the body or to store
elastic recoil energy in preparation for a shortening (concentric) contraction. The muscle …

Background Gait disorders are common in the elderly populations, and their prevalence
increases with age. Abnormal gait has been associated with greater risk for adverse …

Background Habitual walking speed predicts many clinical conditions later in life, but it
declines with age. However, which particular exercise intervention can minimize the age …

Background. Old adults' ability to execute activities of daily living (ADLs) declines with age.
One possible reason for this decline is that the execution of customary motor tasks requires …

Background Age-related gait changes may play a critical role in functional limitations of
older adults. Despite sizable interest in determining how age alters walking mechanics …
