Sentence examples for postural perturbations from inspiring English sources
Two neural control strategies have been identified for maintaining cervical spine stability in an upright neutral posture: reciprocal muscle activation, which is direction-specific to postural perturbations, and co-contraction of agonistic and antagonistic muscles [15].
Through the vestibular apparatus these forces are detected, and appropriate motor activities are organized to counter the postural perturbations that they induce.
The platform is capable of measuring destabilized postural perturbations in dynamic and static postural conditions.
Twelve participants were presented temporally-predictable postural perturbations under four test conditions.
To understand and examine the relation between postural response latencies obtained during postural perturbations and representative measures of balance during standing (sway variables) and walking (trunk motion).
Finally, although our five force constants method could be used, the actual value obtained for the maximum allowable vertical force may vary with other safety harness systems and postural perturbations.
Eye-head coordination during postural perturbation as a predictor of falls in community-dwelling elderly women.
This enabled us to verify that any recorded postural perturbation in the Upright condition were not merely due to object displacement in the visual field.
Sequential orientation values were calculated on each body segment within each tenth of a cycle (corresponding to 10 s at 0.01 Hz and to 1.67 s at 0.06 Hz) of platform movement, in order to assess the time course of the segmental orientation process, especially at the maximum platform tilt angle, i.e. under maximum postural perturbation conditions.
Recently, dynamic stability (the ability to maintain balance following a postural perturbation) has emerged as a potentially important aspect of defining and modifying fall risk [ 8].
The neural control of volitional limb movements differs in some fundamental ways in comparison to reactions that are evoked by postural perturbation [ 18, 30].
