چکیده

مقدمه و اهداف
هدف مطالعه حاضر ارزیابی ویژگی­های روانسنجی ابزار مقیاس تعادلی برگ در افراد دارای قطع عضو اندام تحتانی شهر تهران بود.
مواد و روش ­ها
تحقیق حاضر از نوع توصیفی و طرح تحقیق مقطعی بود. نمونه تحقیق حاضر شامل 83 نفر (سن 5±38 سال) از افراد دارای قطع عضو اندام تحتانی (38 قطع عضو ورزشکار و 45 قطع عضو غیرورزشکار) بود که به­صورت نمونه‌گیری در دسترس و بر اساس معیارهای ورود به مطالعه انتخاب شدند. ابزار تحقیق حاضر، آزمون تعادل برگ، پرسشنامه ارزیابی اندام مصنوعی (بخش مربوط به تحرک)، آزمون 2 دقیقه راه رفتن، آزمون تحرک عملکردی L، ترازوی دیجیتال و قدسنج جهت تعیین شاخص توده بدنی بود. برای تحلیل داده­ها از روش‌های آماری آلفای کرونباخ، ضریب همبستگی درون­طبقه­ای، همبستگی پیرسون و تی­مستقل استفاده شد.
یافته­ ها
پایایی همسانی درونی برای مقیاس تعادلی برگ 89/0=α و دامنه تغییرات آلفای کرونباخ در خرده­مقیاس­های تعادلی برگ 0/73 تا 0/76 به دست آمد. ضریب همبستگی درون­خوشه­ای (ICC) برای همه زیرسازه­ها بزرگتر از 90% به دست آمد. ضریب همبستگی درون­خوشه­ای (ICC) برای ارزیابی پایایی درون­ارزیاب و بین ارزیاب­ها برای تمام خرده ­آزمون­ های تعادلی برگ بزرگتر از 90% به دست آمد. شاخص روایی محتوا (CVI) برابر با 0/94 بود. ضرایب همبستگی مربوط به پایایی سازه­ای آزمون تعادلی برگ با هر یک از آزمون­ های ارزیابی اندام مصنوعی (0/57=r)، آزمون دو دقیقه راه رفتن (0/25-=r)، آزمون تحرک عملکردی (0/48-=r) و آزمون اعتماد تعادل ویژه فعالیت (0/59=r) بود. نتایج آزمون تی مستقل نشان داد آزمون تعادل برگ بین افراد قطع عضو اندام تحتانی ورزشکار و غیرورزشکار دارای روایی افتراقی است (0/05<p).
نتیجه­ گیری
با توجه به تایید روایی و پایایی آزمون تعادلی برگ، می­توان با اطمینان از این ابزار برای ارزیابی افراد دارای قطع عضو تحتانی شهر تهران استفاده کرد.

چکیده [English]

Background and Aims: The purpose of the present study was to evaluate the psychometric properties of the Berg balance scale instrument in Tehran's people lower limb amputations.
 Materials and Methods: A descriptive and cross-sectional study was conducted on 83 individuals (38 athlete and 45 non-athlete amputees) (age: 38±5 years) with lower limb amputation who were selected using convenience sampling based on inclusion criteria. The instruments of the present study were Berg balance test, artificial intelligence (mobility section) questionnaire, two-minute walk test, L functional mobility test, and digital scales to determine body mass index. For data analysis, we used Cronbach's alpha, intra-class correlation coefficient, Pearson correlation, and independent test. 
Results: Internal consistency was obtained for Berg  balance scale (α = 0/89) and Cronbach's alpha variability in Berg balance subscales (0/73 to 0/76). The Intraclass correlation coefficient (ICC) was greater than 90% for all substructures. Also, the Intraclass correlation coefficients (ICC) for evaluating intra-rater reliability and inter-rater reliability was greater than %90 for all leaf balance subscales. Content Validity Index (CVI) was evaluated to be  0/94. Correlation coefficients related to the reliability of the Berg balance test constructs with each of the artificial limb assessment tests (r = 0/57), two-minute walking test (r = -0/25), functional mobility test (r=-0/48), and activity specific balance test (r = 0/59) were found. Independent test-retest results showed that the Berg balance test between athlete and non-athlete lower limb amputation had a discriminant validity (p < 0/05).
Conclusion: Given the validity and reliability of the Berg balance test, this instrument can be used to evaluate lower amputee individuals in Tehran.
