Evaluating central mechanisms for age-related force control deficits of the legs
Advancing age is accompanied by several motor control impairments, including increased movement and force variability. Specifically, older adults display more variable and less accurate submaximal forces than young adults, which have been associated with fall risk in the aged population. These motor control changes take place in muscles in both the upper and lower limbs, and the mechanisms of these alterations are multifactorial, including sources in the peripheral and central nervous systems. Furthermore, inhibitory signaling in the motor cortex is related to force variability in small hand ...
