چکیده

زمینه و هدف: افتادن یک مشکل بهداشتی بزرگ برای سالمندان است که اثرات قابل توجهی بر سلامت و کیفیت زندگی آن ها دارد، اما احتمالاً از طریق توسعه قدرت عضلانی، قابل پیشگیری است.هدف تحقیق حاضر بررسی رابطه بین قدرت عضلات پشت و تعادل پویا و ترس از سقوط در سالمندان بود. روش تحقیق: 68 سالمند زن و مرد با میانگین سنی 5/43±70 سال، قد 8/95± 157/29 سانتی متر،  و میانگین وزنی 9/63 ± 70/46 کیلوگرم؛ به صورت تصادفی از بین افراد داوطلب عضو کانون جهاندیدگان شیراز انتخاب شدند. برای اندازه گیری قدرت عضلات بازکننده ستون فقرات از دینامومتر، تعادل پویا از سیستم ثباتی بایودکس و ترس از سقوط از پرسشنامه تعدیل شده مقیاس کارآمدی افتادن استفاده شد. روش تحقیق حاضر از نوع تجربی و علی رابطه­ای بود و برای استخراج نتایج از روش آماری ضریب همبستگی پیرسون استفاده شد و سطح معنی داری 0/05>p در نظر گرفته شد. یافته ها:  نتایج نشان داد که بین قدرت عضلات پشت با تعادل پویا در سطح قدامی- خلفی همبستگی منفی معنی دار وجود دارد (0/0001=p)، در حالی که بین قدرت عضلات پشت با تعادل پویا در سطح داخلی- خارجی  همبستگی معنی دار مشاهده نگردید (0/29=p). به علاوه، بین قدرت عضلات پشت با ترس از سقوط، همبستگی مثبت معنی­دار به دست آمد (0/01=p). نتیجه­گیری: قدرت عضلات پشت، عاملی موثر در حفظ تعادل پویا در جهت قدامی- خلفی و ترس از سقوط در سالمندان است.

چکیده [English]

Background and Aim: Falling is a major health problem among elderly that has significant affect their health and life
quality, but it can be possibly prevented by development of muscle strength. The purpose of this study was to investigate
the relationship between strength of spine extensor muscles with dynamic balance and fear of falling in elderly people.
Materials and Methods: 68 elderly men and woman with mean age of 70±5.43 years, height of 157.29±8.59 cm and
weight of 70.64±9.63 kg were randomly recruited among volunteers. Dynamometer, biodex stability system and modified MFES questionnaire were used to assess strength of spine extensor muscles, dynamic balance and fear of falling
respectively. This research was an empirical and causal relationship study, and to elicit the results, Pearson correlation
coefficient was used and significance level was considered if pcorrelation between strength of spine extensor muscles and dynamic balance in anterior-posterior direction (p=0.0001), while no significant correlation was shown between strength of spine extensor muscles and dynamic balance in media-lateral direction (p=0.29). In addition, there was a significant positive correlation between strength of spine extensor muscles and fear of falling (p=0.01). Conclusion: Strength of spine extensor muscles is an effective factor to maintain balance at anterior-posterior direction and fear of falling
