Abstract Background and Purpose. Trunk motion plays an important role in achieving both
sit-to-stand and stand-to-sit transfers. However, these 2 body transfers depend on different …

A common way of predicting falling risks in elderly people can be to study center of pressure
(CP) trajectories during undisturbed upright stance maintenance. By estimating the …

Background. The purpose of this study was to analyze the electromyographic and kinematic
characteristics of postural responses of 24 healthy older adults both prior to and immediately …

In this experiment, we induced muscular fatigue of ankle plantar-flexors to examine how it
deteriorates the regulation of bipedal quiet upright standing. Postural stability was assessed …

Background Aging, being a natural process, involves many functional and structural
changes within the body. Identifying the age-related postural changes will provide insight …

The purpose of this study was to investigate the effects of holding external loads on postural
sway during upright stance across age decades. Sixty-five healthy adults (females, n= 35) …

Many elderly persons are engaging in resistance exercise to counter muscle atrophy due to
aging. Here, the acute effects of resistance exercise on postural control mechanisms were …

This study examined the reliability of ground reaction force (GRF) parameters during sit-to-
stand (STS) movements and the relationships between the GRF parameters and lower limb …

Background Muscle co-contraction is the simultaneous contraction of agonist and antagonist
muscles crossing a joint, and it increases with age. This study primarily aimed to clarify the …

Background: Due to the often-reported decrease in postural stability in the elderly, it is
important to understand factors that may contribute to reduced postural stability. It is possible …
