چکیده

هدف از تحقیق حاضر، بررسی ارتباط بین نمره‌های آزمون برگ با قدرت آبداکتورهای ران و پلانتار فلکسور مچ در زنان سالمند است. 32 زن سالمند (میانگین سن ­­98/5±20/66 سال، وزن ­78/5±60/62 کیلوگرم و قد 8/7±­94/159 سانتی‌متر) داوطلبانه در تحقیق شرکت کردند. اجزای آزمون برگ به چهار دسته تقسیم شد: 1. حفظ وضعیت، 2. حرکت درون تکیه‌گاه، 3. حرکت خارج تکیه‌گاه و 4. حرکت درون و خارج تکیه‌گاه. حداکثر انقباض ارادی (MVC) عضلات آبداکتور ران و پلانتار فلکسور مچ پا به‌وسیلۀ دستگاه دیناموتر دستی (MMT) اندازه­گیری شد. ارتباط بین اجزای آزمون برگ و قدرت عضلات با استفاده از ضریب همبستگی پیرسون در سطح معناداری 05/0 بررسی شد. نتایج نشان داد که بین قدرت آبداکتورهای ران و پلانتارفلکسورهای مچ پا و نمره‌های آزمون برگ در زنان سالمند ارتباط معناداری وجود دارد (05/0≥ᴩ). همچنین نتایج نشان داد که میزان همبستگی قدرت آبداکتورهای ران با بخش‌های آزمون برگ (62/0-54/0r = ) بیشتر از قدرت پلانتارفلکسورهای مچ با بخش‌های آزمون برگ بود (53/0-35/0r = ). بنابراین با توجه به نتایج تحقیق حاضر، می­توان نتیجه گرفت که قدرت آبداکتورهای ران و پلانتارفلکسورهای مچ پا با اجرای آزمون برگ ارتباط دارد و کاهش قدرت عضلات مذکور، کاهش اجرای آزمون برگ را به‌همراه دارد.

چکیده [English]

The aim of this study was to determine the relationship between the Berg balance test scores and strength of hip abductors and ankle plantar flexors in elderly women. 32 elderly females (mean age: 66.20±5.98 yr, weight: 62.60±5.78 kg, height: 159.94±7.8 cm) voluntary participated in this study. Berg Balance Test (BBT) functions were divided into four categories: 1. Position maintenance, 2. movement within base of support, 3. Movements out of base of support, 4. Movements in and out of base of support. Maximum Voluntary Contraction (MVC) of hip abductor and ankle plantar flexor muscles were measured by Manual Muscle Test (MMT). Pearson correlation coefficient was used to determine the relationship between Berg functions and muscle strength at significance level of 0.05. Results showed a significant relationship between hip abductors and ankle plantar flexors strength and BBT scores in elderly women (P≤0.05). Also, the correlation values between hip abductors and BBT functions (r=0.54-0.62) were higher than plantar flexor strength and BBT functions (r=0.35-0.53). In conclusion, it can be concluded that there were significant relationships between hip abductors and ankle plantar flexors strength and BBT functions and decreased ankle plantar flexors and hip abductors strength was associated with decreased BBT functions
