Variability in inter-joint coordination during walking of elderly adults and its association with clinical balance measures

Relationship between Center of Pressure and Local Stability of the Lower Joints during Walking in the Elderly Women

“…However, the results were consistent with the study by Chiu & Chou (2012, 2013, which reported that decreased variability in the pattern of coordination between joints during walking appears with aging and it increases the risk of falls. In order to determine the relationship between variability and stability during exercise, additional studies that take into account various situations, such as variability variables, joints and segments, and age are needed.…”

Age-related differences in inter-joint coordination during stair walking transitions

“…This coordination variability is necessary for the transitions between movement conditions or gradual adaptation to a new movement pattern, especially for coordination systems with multiple degrees of freedom [28]. In addition, coordination pattern and variability between distal joints (knee-ankle) has been associated with the fine tuning of foot trajectories for a secure foot clearance and progression against falling in older adults [15,29].…”

Effect of Different Cognitive Loads on Gait Stability in Younger and Older Adults

“…An increase in the cognitive load in different tasks while walking (such as counting) imposes a different cognitive load on the central processing system [7]. According to the theory of capacity sharing in the dual-task paradigm, implementing additional tasks in walking may change walking features or the implementation of the second task or both [8]. Dubost et al reported an increase in walking variability in the elderly while performing simple computational tasks [9].…”
