چکیده

مقدمه و اهداف
امروزه کمردرد یکی از مشکلات شایع است؛ بنابراین هدف از مطالعه حاضر تاثیر سه روش تمرینی تصویرسازی حرکتی، فعال و ترکیبی (تصویرسازی و فعال) بر الگوی حرکتی هایپراکستنشن ران در زنان هایپرلوردوز کمری است.
مواد و روش ­ها
در پژوهش حاضر 36 زن دارای هایپرلوردوز کمری در سه گروه قرار گرفتند. گروه­ها به مدت شش هفته و هفته ­ای سه جلسه به تمرینات پرداختند. درجه لوردوز کمری با استفاده از خط­کش منعطف و فعالیت الکترومایوگرافی عضلات منتخب لگنی در حرکت هایپراکستنشن ران در وضیعت دمر با استفاده از الکترومایوگرام سطحی قبل و پس از مداخله اندازه­گیری شد.
یافته ­ها
نتایج تحقیق حاضر نشان داد بین سه روش تمرینی اختلاف معنادار وجود دارد (P=0.005). بین روش تمرینی تصویرسازی ذهنی با روش تمرینی فعال و ترکیبی تفاوت معنادار وجود دارد، ولی بین دو روش فعال و ترکیبی تفاوت معنادار وجود ندارد.
نتیجه­ گیری
به نظر می‌رسد تمرینات ترکیبی در تغییر فعالیت کمربند لگنی موثر بوده، پیشنهاد می­شود از تمرینات تصویرسازی حرکتی در کنار تمرینات جسمانی در اصلاح ناهنجاری­ها بهره گرفت.

چکیده [English]

Background and Aims: The purpose of the present study was to investigate the effect of three methods of kinesthetic imagery, active, and combination exercises on electromyographic pattern of femur hypertension in women with hyperlordosis.
Materials and Methods: In the current investigation, 36 women with lumbar hyperlordosis were chosen and divided into three groups of imagery, active and combined exercises. The groups trained for six weeks, three times a week. The lumbar lordosis was measured making use of flexible ruler and electromyographic activity of the selected muscles of pelvic in the femur motion in prone condition using surface electromyogram before and after the intervention.
Results: There was a significant difference between the three training methods (P = 0.005). 
Conclusion: According to the results, combination exercises were effective in changing pelvic muscle activity; therefore, it is suggested that kinesthetic imagery exercises be used along with physical exercises to correct abnormalities.
