Balance Deficits in Elderly Population

Impaired balance is common in old population with the resultant high risk of falls. It may increase the rate of mortality and morbidity, as well as decreased functional abilities. The current study aimed at investigating the changes of balance in elderly population. Thirty male participants were included and were assigned into two equal groups; young group aged 20 to 26 years and elderly group aged 60 to 69 years. Stability index (SI) and dynamic limit of stability from standing position were evaluated by Biodex stability system. Balance also was assessed clinically by the functional reaching test (FRT). The results showed significant increase in stability index including overall, antroposerior (A/P) and mediolateral (M/L) stability indexes, decrease in the directional control, increase in the time elapsed for completing the test and finally decreased FRT scores in the older group compared to that of the younger one. There was also significant positive correlation between directional control and FRT scores (p<0.05). It can be concluded that there are age- related changes of balance resulting in poor performance in standing position and decreased functional reaching in elderly people.
