The present study measured grasp force in 10 elderly and 9 young adult individuals, during grasp and vertical lift of a small object, using a precision.
В abstract diminished tactile sensibility and impaired hand dexterity have been reported for elderly individuals. Reports that younger adults with severely impaired tactile sensibility use excessive grasp force during routine grasp and manipulation tasks raise the possibility that elderly persons likewise produce large grasp forces that may contribute to impaired dexterity.

В this study revisited the hypothesis that older adults lose some ability to efficiently control precision grip force. A previous study demonstrated such a decrement in older adults performance in a vertical lift and support maneuver. This study employed a similar paradigm in which dynamic forces were applied with a simulated hand tool while measuring grip force and force applied with the tool.
В the evolution of the opposing thumb and prehensile grasp are refinements of hand control that have been major factors leading to the dominance of the human species throughout the world in an extensive range of geographic and climatic domains.
В these improvements could enhance quality of life in older adults because many daily tasks involving hand manipulation require fine control of pinch force, hand steadiness, and rapid hand movements. Skilled finger movement training improves pinch force steadiness. Impaired control ability of finger force has been reported in elderly subjects.
Age-related changes were investigated in the control of precision grip force during the lifting and holding of objects with slippery (silk) and nonslippery (sandpaper) surface textures. Two groups of active elderly adults comprising individuals aged 6979 years (n 10), and 8093 years (n 10) together with a group of young adults aged 1832 years (n 10) participated in the study.
В this study aims toward an investigation and comparison of the digital force control and the brain activities of older adults and young groups during digital pressing tasks.
We studied effects of healthy aging on three components of the internal force vector during static prehensile tasks. Young and older subjects held an instrumented handle using a five-digit prismatic grasp under different digit configurations and external torques.
The control of movements is a complex interaction of cognitive and sensorimotor systems. Researchers in movement science aim to understand how an action is produced and what mechanisms are involved in regulating the movement. Motor control declines in older adults include changes in both the peripheral and the central nervous system, which lead to an array of behavioral decrements (salthouse.).
