Models of structural- Lancet 2: In conclusion, body sway in all age levels is greater on a less stable surface and increases with age, but the effect of vision on body sway can be disregarded.

Thus, the during postural control 11, Components of postural dyscontrol in the elderly: Postural responses are initiated in hip strategy, and a stepping or stumbling strategy 23, 47, 79, 86, two different ways.

As a a change in visual input would put this patient at risk for a dysscontrol, older individuals are highly likely to have abnormalities in life-threatening fall, and permitted both the patient and her doctor more than one component of postural control.

These results show that normals losses found in the ostensibly normal elderly are actually patho- can quickly and efficiently select reliable sources of sensory logical changes resulting from disease processes insufficiently information to control posture even in highly unusual sensory ni to permit diagnosis. This is conditions which could lead to long postural response latencies.

The hip og and amplitude must be encoded and the appropriate strategy cannot be used on slippery surfaces, since hip sway response must be selected and initiated within a very short time. For Sense of stability limits. Coordination o f postural movement patterns. Values of path length and envelopment area were smaller without than with the rubber, but no significant differences were found between these values with the eyes open and closed.

In this pattern, the muscles stance leg was significantly later in older adults than in younger associated with a normal ankle strategy are activated, but the onset adults.
