Background. Lower limb muscle power impairments are modifiable factors underlying
mobility limitations in older adults. This study examined relationships between upper and …

Upright standing involves small displacements of the center of mass about the base of
support. These displacements are often quantified by measuring various kinematic features …

Previous studies reported a significant association between postural control and lower-limb
strength of several muscle groups, however, they were focused especially on knee muscles …

To investigate the functional significance of force fluctuations during voluntary contraction
with a select muscle group, we examined the association between force fluctuations during …

Objective To examine how muscle activity over the entire gait cycle changes with increasing
age. Methods Electromyography data of the erector spinae, rectus femoris, vastus lateralis …

Purpose We explored changes in muscle interactions during healthy aging as a window into
neural control strategies of postural preparation to action/perturbation. In particular, we …

Background sufficient research has not been conducted to determine the role of core and
lower limb muscles in providing balance in older people. Objective to investigate the …

Objective To investigate the effect of gastrocnemius muscle fatigue on postural control ability
in elderly people. Methods Twenty-four healthy elderly people participated in this study. The …

This study determines (1) the correlation between mobility and balance performances with
physiological factors and (2) the relationship between foot postures with anthropometric …

Older adults demonstrate increased amounts of postural sway, which may ultimately lead to
falls. The mechanisms contributing to age-related increases in postural sway and falls in the …
