The purpose of this study was to clarify the difference in muscle coactivation during postural
control between older and young adults and to identify the characteristics of postural control …

Background. Recently, several studies have reported age-associated increases in muscle
coactivation during postural control. A rigid posture induced by strong muscle coactivation …

Recently, several studies have reported that muscle coactivation during static postural
control increases with aging. Although greater muscle coactivation during quiet standing …

Background Muscle co-activation plays an important role in enhancing joint stability for
movement regulation during motor learning activities. In normal aging, greater muscle co …

Objectives: postural disturbances can arise from performing functional tasks and from
external perturbations. Identification of sensorimotor factors associated with both types of …

Background Agonist and antagonist muscle co-contractions during motor tasks are greater
in the elderly than in young adults. During normal walking, muscle co-contraction increases …

Although motor output of the postural function clearly influences postural performance in
young and older subjects, no relationship has been formally established between them …

Older adults use a different muscle strategy to cope with postural instability, in which they 'co-
contract'the muscles around the ankle joint. It has been suggested that this is a …

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 …

It has been reported that the elderly use co-contraction of the tibialis anterior (TA) and
plantarflexor muscles for longer duration during quiet standing than the young. However, the …
