چکیده
مطالعه حاضر با هدف بررسی اثر هشت هفته تمرینات ثبات عصبی-عضلانی پویا (DNS) بر تعادل، پیشگیری از سقوط و قدرت اندام تحتانی زنان سالمند سالم انجام شد. در این مطالعه نیمه‌تجربی با طرح پیش‌آزمون-پس‌آزمون، از بین زنان سالمند سالم(۶۰-۷۹ سال) مشهد، 30 آزمودنی بصورت هدفمند انتخاب و تصادفاً در دو گروه تمرین(تمرینات DNS) و کنترل تقسیم شدند. فاکتورهای تعادل ایستا با آزمون تعادلی برگ و شارپندرومبرگ، تعادل پویا با آزمون برخاستن و برگشتن، پیش‌بینی خطر سقوط با مدل شوموی و قدرت عضلات پایین تنه با آزمون صندلی ایستاده ارزیابی شدند. از آزمون تی‌همبسته و تی‌مستقل جهت آنالیز داده‌ها استفاده شد. گروه تمرینی در پس-آزمون نسبت به پیش‌آزمون و نسبت به گروه کنترل در همه فاکتورها بهبود معناداری نشان داد. نظر به یافته‌های حاضر، اثر برنامه تمرینی DNS در بهبود متغیرهای پژوهش تایید و استفاده از آن در برنامه‌های مراقبتی سالمندان توصیه می‌شود.

چکیده [English]
The aim of this study was to investigate the effect of eight weeks of DNS training on dynamic and static balance, fall prevention and lower limb strength in healthy elderly women. This is a quasi-experimental research with pre-post-test. Thirty healthy elderly women (60-79 years old) selected purposefully and divided into two groups of exercise (DNS) and control randomly. Static balance were assessed by the Berg and Sharpendromberg balance test, dynamic balance by the Timed Up and Go test, prediction of fall risk by the Shumway-Cook model, and lower extremity strength by the Chair Stand test. Paired t-test and independent t-test were used to analyze the data. The training group showed a significant difference between pre and post-test and also compared to control group in all factors. According to the present findings, the effect of DNS in improving research variables is confirmed and its use in elderly care programs is recommended.
