چکیده
از دست دادن تعادل و زمین خوردن یکی از اصلی ترین مشکلات دوران سالمندی است. استفاده از روش های تمرینی مختلف یکی از بهترین رویکردها برای بهبود این فاکتور در این قشر است. تاثیر دستکاری قیود تکلیف یکی از روش هایی است که به نظر مرسد می تواند بر بهبود شاخص های تعادلی در سالمندان موثر باشد. ، از این رو تحقیق حاضر در نظر دارد به بررسی تاثیر دستکاری قیود تکلیف بر شاخص های تعادل سالمندان سالم بپردازد. به این منظور 30 سالمند سالم به صورت تصادفی انتخاب و در دو گروه مداخله و کنترل تقسیم بندی شدند. گروه مداخله اقدام به انجام تمرینات دستکاری قیود تکلیف به مدت 8 هفته و به صورت 3 بار در هفته پرداختند. گروه کنترل نیز، طی مدت اجرای تحقیق به فعالیت عادی خود ادامه دادند. شاخص های تعادلی با استفاده از دستگاه بایدوکس بررسی شدند. نتایج تحقیق نشان داد اعمال پروتکل تمرینات دستکاری قیود تکلیف باعث بهبود شاخص های تعادلی در گروه مداخله میشود. نتایج آزمون تحلیل کوواریانس با حذف اثر پیش آزمون نشان داد، هر سه شاخص ثبات کلی، ثبات قدامی خلفی و ثبات میانی جانبی در گروه مداخله بهبود معناداری را نسبت به گروه کنترل داشت(001/0=P).
نتایج این پژوهش موید تأثیر تمرینات با دستکاری قیود تکلیف بر بهبود تعادل و در سالمندان است. با بهبود این توانایی خطر زمین خوردن در این قشر از جامعه کاهش مییابد.

چکیده [English]
Background: 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
Methods: 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.
Results: 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).
Conclusion: 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.
