چکیده

مقدمه: در بیماران با سندروم درد کشککی­رانی افتادگی لگن و والگوس داینامیک زانو وجود دارد که از جمله مکانیسم­های وقوع آن درد و ترس از درد گزارش شده است. بنابراین هدف مطالعه حاضر اثربخشی دوازده هفته تمرینات بازخورد عصبی بر شدت درد ادراکی، ترس از درد، افتادگی لگن و شاخص والگوس داینامیک زانو در مردان مبتلا به سندروم درد کشککی­رانی است.
روش ­ها: این مطالعه شامل 32 نفر بیمار مبتلا به سندروم درد کشککی­رانی است که بصورت تصادفی به دو گروه تجربی (16 نفر) و کنترل (16 نفر) تقسیم شدند. برای ارزیابی درد از مقیاس­ آنالوگ بصری، ترس از درد از پرسشنامه ترس از درد مک نیل، افتادگی لگن و شاخص والگوس داینامیک طی پایین آمدن از پله از دوربین و نرم افزار کینوا استفاده شد. گروه تجربی طی یک دوره دوازده هفته­ای، سه جلسه در هفته و هر جلسه 30 دقیقه تمرین بازخورد عصبی را انجام دادند و گروه کنترل طی این وهله زمانی تحت هیچ گونه مداخله درمانی قرار نگرفتند. جهت تجزیه و تحلیل داده­ها از نرم افزار SPSS  ورژن 21 و روش آماری کوواریانس استفاده شد.
یافته ­ها: نتایج تجزیه و تحلیل داده­ها نشان می­دهد که گروه تجربی نسبت به گروه کنترل پس از دوازده هفته تمرین بازخورد عصبی بهبودی معناداری در کاهش درد (001/0P= )، کاهش ترس از درد (004/0P= ) والگوس داینامیک زانو (005/0P= ) کسب کرده است و در زاویه افتادگی لگن بهبودی معناداری حاصل نشده است(45/0P= ).
نتیجه­ گیری: به نظر می­رسد که افتادگی لگن و شاخص والگوس داینامیک زانو تحت تاثیر عوامل روانشناختی درد و شدت درد اداراکی باشند و شاخص والگوس داینامیک زانو نسبت به افتادگی لگن بطور معناداری تحت تاثیر شدت درد ادارکی و ترس از درد باشد که پس از دوازده هفته تمرین بازخورد عصبی بطور معنادرای زاویه آن کاهش یافته است.

چکیده [English]

Introduction: Patellofemoral Pain Syndrome is accompanied by Pelvic Drop and Valgus Dynamic Knee. Pain And fear of pain have been reported as some mechanisms of its occurrence. The present study is to investigate the effect of twelve-week neurofeedback training on perceptual pain intensity, fear of pain, pelvic drop, and dynamic knee valgus index in men with Patellofemoral Pain Syndrome.
Methods: 32 patients with PFPS participated in this study. They were randomly divided into experimental (n = 16) and control (n = 16) groups. The instruments used in this study consist of the VAS scale for pain, McNeil questionnaire for fear of pain, camera and Kinova Software for pelvis drop and dynamic valgus index when going down the stairs. The experimental group performed neurofeedback training for twelve weeks, 3 times per week, and 30 Min per Session; however, the control group did not receive any treatment during this time.  The covariance statistical method was used through SPSS software, version 21, for data analysis.
Results: The results showed that the experimental group after twelve weeks of neurofeedback training had significant improvement in pain reduction(0/001), fear of pain (P = 0.004) and Valgus Knee Dynamics Index (P = 0.005); however, there was no significant improvement in drop pelvis (P = 0.45).
Conclusion: It seems that the pelvic drop and Knee Dynamic Valgus Index are influenced by perceptual pain intensity and fear of pain. Dynamic Knee Valgus Index has been significantly influenced by perceptual pain intensity and fear of pain since it decreased after twelve weeks of neurofeedback training.
