چکیده

هدف از پژوهش حاضر، تعیین تأثیر تکلیف دوگانه، مجرد و ترکیبی بر راه‌رفتن زنان سالمند با تجربۀ افتادن و بدون تجربۀ افتادن می­باشد. بدین­منظور، 120 زن سالمند شهرستان بابل که در دامنۀ سنی 80ـ60 سال قرار داشتند­ به صورت داوطلبانه انتخاب شدند و به­شکل تصادفی در گروههای کنترل و تمرینی دوگانه، مجرد و ترکیبی جای گرفتند. جهت سنجش کیفیت راه­رفتن سالمندان­ از آزمون برخاستن و حرکت­کردن زماندار استفاده شد. پس از مرحلۀ پیش­آزمون، گروه‏های مختلف تمرینی بر­اساس برنامۀ مشخص با توجه به گروه خود،­­ به تمرین راه­رفتن با شرایط تکلیف مجرد، دوگانه و ترکیبی پرداختند و پس از دوماه، مجدداً در آزمون برخاستن و حرکت­کردن زماندار حضور یافتند. شایان­ذکر است که آزمون در دو شرایط تکلیف مجرد و تکلیف دوگانه برای تمام گروه‏ها انجام پذیرفت. نتایج آزمون تحلیل واریانس مختلط نشان می­دهد که اثر مداخله و اثر تعاملی مداخله در گروه در دو شرایط آزمون با اجرای تکلیف مجرد و تکلیف دوگانه معنادار می­باشد (0.05P اما تفاوت بین این دو شرایط در پس­آزمون معنادار نیست. این احتمال وجود دارد که افزایش قابلیت شناختی و جسمانی زنان سالمند، زمینهساز بهبود امتیازات کیفیت راه­رفتن آن­ها بوده است.

چکیده [English]

The main aim of this study was to determine the effect of dual-task, single-task, and combined-task training on older adults’ gait, with or without the experience of falling. For this purpose, we recruited 120 volunteers in Babol in the 60–80 age range. The participants were randomly divided into different groups, including: two control groups, two experimental groups assigned with single task, two experimental groups assigned with dual task, and two groups assigned with combined task. To evaluate the quality of gait in older adults, we applied the ‘Timed up and go test (TUG).’ After pre-examining the participants according to the task their groups were assigned, they participated in single-task, dual-task, and combined-task exercises. After about two months, the subjects participated in TUG again. All groups were assessed in both single-task and dual-task conditions. The results of mixed ANOVA test showed that the effect of intervention, and the interactive effect of intervention and group under both test conditions were meaningful, but the post-test difference between these two conditions was not significant. Probably, the increase in cognitive and physical ability is the key reason for a better quality of gait.
