چکیده

مقدمه و اهداف
مشکلات تعادلی و شناختی منجر به کاهش تحرک در بیماران سندرم داون می­گردد. بنابراین هدف از مطالعه حاضر، بررسی عملکرد تعادلی و رابطه آن با ظرفیت حافظه کاری در کودکان با و بدون سندرم داون بود.
مواد و روش­ ها
در مطالعه حاضر 20 نفر از افراد دارای سندرم داون با 20 فرد سالم که از لحاظ سن و جنس و سایر ویژگی­های دموگرافیک مشابه با آن‌ها بودند، مورد آزمون قرار گرفتند. عملکرد تعادل ایستا و پویای افراد به‌ وسیله آزمون ایستادن روی پای برتر با چشم باز و بسته، آزمون عملکردی کشش دست‌ها، آزمون راه رفتن تاندم، آزمون زمان رفتن و برگشتن، آزمون چرخش 360 درجه و آزمون تعادل Y اندازه­گیری شد. ظرفیت حافظه کاری آزمودنی­ها توسط خرده­مقیاس شمارش روبه­جلو و معکوس مورد سنجش واقع گردید. از آزمون تی تست مستقل و آزمون همبستگی پیرسون در سطح معناداری 05/0>p استفاده شد.
یافته­ ها
نتایج تحقیق حاضر نشان داد همبستگی معناداری بین حافظه کاری و برخی از فاکتورهای تعادل وجود دارد (05/0>p). همچنین عملکرد تعادلی بیماران سندرم داون در آزمون­های انجام­گرفته به طور معناداری کمتر از افراد سالم بود. ظرفیت حافظه کاری در بیماران سندرم داون اختلاف معناداری با افراد سالم نشان داد (05/0>p).
نتیجه­ گیری
نتایج نشان‌دهنده تأثیر عملکرد شناختی بر کنترل قامت بود. بنابراین علاوه بر تقویت سیستم عضلانی و حسی، مداخلات شناختی نیز می­توانند در بهبود تعادل تأثیرگذار باشند.

چکیده [English]

Background and Aim: Balance and cognitive problems lead to reduced mobility in Down syndrome patients. The aim of the present study was to evaluate the balance features and its relationship with memory capacity in children with and without Down syndrome.
Materials and Methods: In the present study, 20 participants with Down syndrome and 20 healthy individuals identical in age and sex and other demographic characteristics were tested. Participants' static and dynamic balance performances were measured using test of standing on the dominant leg with open and closed eyes, functional reach test, tandem walking test, time up and go test, 360 degree rotation test, and Y balance test. Also, each participant's capacity of working memory was measured via the forward and backward counting. Independent t-test and Pearson correlation test were used at the significance level of p < 0.05.
Results: The results showed that there is a significant relationship between working memory and some of the balance factors (p < 0.05). Also, the balance performance of Down syndrome patients was significantly lower than that of healthy participants. The working memory capacity in the patients with syndrome showed a significant difference with healthy participants (p < 0.05).
Conclusion: The results showed that the cognitive function can affect postural control. Therefore, in addition to reinforcement of the muscular and sensory system, cognitive interventions can also be effective in improving balance.
