The effect of task constraints manipulation on balance indexes of healthy elderly adults

falling and losing balance is one the most Important problem in elderly. Exercise interventions are one the best approach to resolve this problem. Task constraints manipulation is one this approach seems it can improve balance indexes in elderly population. So the aim of current study is to investigate effect of task constraints manipulation on balance indexes of healthy elderly adults Thirty elderly people were selected to participate in the research, and they were randomly divided into control and intervention groups. The intervention group participated in task constraints manipulation exercises for 8 weeks (3 times per week), while the control group lived without any interventions. The balance indexes were evaluated using the Biodex system. The results showed task constraints manipulation exercises improve the balance indexes in intervention group. The result of ANCOVA test revealed a significant improvement in the scores of postural control and balance (P<0.05). The results of this research confirm the effect of task constraints manipulation exercises on improving balance indexes in the elderly. Balance improvement finally can lead to reduce the fall risk in elder population.
