چکیده

مقدمه و اهداف
امروزه سندرم درد پتلوفمورال که از آن به عنوان سیاه­چاله­ی ارتوپدی یاد شده است، یکی از شایع­ترین مشکلات اسکلتی-عضلانی زانو در افراد ورزشکار و غیرورزشکار است. سینماتیک­های تغییریافته از جمله ولگوس داینامیک اندام تحتانی به درد پتلوفمورال کمک می­کند. استفاده از یک دستگاه بازخورد بصری می­تواند بر اصلاح راستای داینامیک زانو مفید باشد. تحقیق حاضر به منظور مقایسه تأثیر سه نوع بازخورد آینه، فیلم خام و بازخورد بینایی آنی بر راستای داینامیک اندام تحتانی و درد در افراد دارای سندرم درد پتلوفمورال انجام گرفت.
مواد و روش ­ها
در مطالعه حاضر تعداد 52 زن با میانگین سن 16/4±42 سال دارای سندرم درد پتلوفمورال شرکت کردند. راستای داینامیک اندام تحتانی و درد به ترتیب با استفاده از تست اسکات تک­پا و با استفاده از نرم­افزار Dartfish ProSuite 7 و مقیاس بصری درد قبل و بعد از اصلاح راستای داینامیک اندام تحتانی همراه سه نوع بازخورد آینه، فیلم خام و بازخورد بینایی آنی، اندازه‌گیری شد.
یافته­ ها
یافته­ها نشان داد که هر سه روش بازخورد آنی باعث ایجاد تغییرات معنادار در راستای داینامیک اندام تحتانی می­شود، اما تاثیری بر درد ندارد.
نتیجه­ گیری
به نظر می‌رسد اصلاح راستای داینامیک اندام تحتانی با استفاده از سه نوع بازخورد آینه، فیلم خام و بازخورد بینایی بر راستای داینامیک اندام تحتانی در افراد دارای سندرم درد پتلوفمورال تأثیرگذار بوده است، اما تفاوت معناداری بین بازخوردهای مختلف مشاهده نشد.

چکیده [English]

Background and Aim: Patellofemoral pain syndrome, described as the black hole of orthopedics, is one of the most common musculoskeletal complaints in athlete and non-athlete populations. Altered kinematic, including dynamic lower extremity valgus, helps with the patellofemoral pain. Using a visual feedback device can help in correction of dynamics knee alignment. The purpose of the present study was to compare the effects of mirror, raw video, and real-time visual feedbacks on dynamic lower limb alignment and pain in individuals with patellofemoral pain syndrome.
Materials and Methods: In the current study, 52 women with a mean age of 42±4.16 yrs with patellofemoral pain syndrome participated. The lower extremity dynamics and pain were measured using single leg squat and the Dartfish Pro Suite 7 software, and visual analog scale before and after correction of the dynamic lower limb alignment with three types of feedback: mirror, raw video, and real-time visual feedback.
Results: The results revealed that all three types of feedback mirror, raw video, and real-time visual biofeedback have a significant effect on lower extremity alignment, but the results for pain were not observed to be significant.
Conclusion: According to the results, all the three types of mirror feedback, raw film and visual feedback influenced the dynamic lower limb alignment in individuals with patellofemoral pain syndrome, but there was no significant difference between the effects of immediate feedbacks.
