Abstract
Introduction: Falls
are one of the major problems among the elderly population. It has been
established that people with dementia fall
down more often. It is believed that this is a
consequence of risky decision making by people with dementia resulting
from
cognitive deterioration. The aim of the present
study was to evaluate the relationship between cognitive status and
postural
stability while standing.
Methods: A total of 47
people, aged 71.6 years on average (±7.2), were divided based on
results of the Mini Mental State Examination
(MMSE) into a dementia group (MMSE ≤ 23) and a
control group (MMSE > 23). Postural stability was tested using a
force plate
(with eyes open, with eyes closed, and with
visual biofeedback). The parameters of movement of the center of
pressure were
analyzed.
Results: Both in test with eyes open and eyes closed, significant difference was shown between the dementia group and the control
groups. In visual feedback test, the dementia group showed 32% poorer performance than the controls.
Conclusion: The falls experienced in dementia group may be caused by a disturbed balance control process of the central nervous system.
