چکیده
زمینه و هدف: اختلال در کنترل کمری لگنی منجر به کاهش فعالیت عضلانی، کاهش انتقال نیرو در زنجیره حرکتی، و د ر نتیجه پتانسیل وقوع آسیب های اندام تحتانی را افزایش می دهد. هدف از این تحقیق بررسی هشت هفته تمرینات ثبات عصبی عضلانی پویا بر شاخص‌های عملکرد حرکتی، کینماتیکی راه رفتن و آسیب اندام تحتانی در دانش آموز با ضعف کنترل کمری لگنی بود. روش شناسی: 30 نفر از دانش آموزان دختر با میانگین سنی 75/0±65/16 سال، قد 11/4 ±80/161 سانتی متر، وزن 64/5 ± 70/62 کیلوگرم که دارای ضعف کنترل کمری لگنی بودند به صورت هدفمند انتخاب و به شکل تصادفی به دو گروه تجربی (15 نفر) و کنترل (15 نفر) تقسیم شدند. گروه تجربی تمرینات ثبات عصبی عضلانی پویا را به مدت هشت هفته، سه جلسه در هفته برای مدت 60 دقیقه انجام دادند، در حالی که گروه کنترل مداخله ای را دریافت نکردند. برای ارزیابی کنترل کمری-لگنی از دستگاه بایوفیدبک پرشر، تعادل ایستا از تست‌ لک‌لک، تعادل پویا آزمون Y، خطای فرود با آزمون سیستم امتیازدهی خطای فرود، عملکرد حرکتی اندام تحتانی از آزمون (تست پرش تک‌پایی، پرش لی 3 تایی، آزمون پرش لی 6 متر در زمان، آزمون پرش لی متقاطع) استفاده گردید یافته ها: مطالعه حاضر، اثر تمرینات ثبات عصبی عضلانی پویا بر شاخص‌های عملکرد حرکتی011/0، کینماتیکی راه رفتن001/0 و آسیب اندام تحتانی 012/0را معنادار نشان داد((0/05< P).

The effect of eight weeks of exercises (DNS) on movement performance indicators and walking kinematics of students with weak lumbopelvic control

چکیده English

The purpose of this study was to investigate eight weeks of dynamic neuromuscular stabilization exercises on movement performance indicators, walking kinematics and lower limb damage in students with weak lumbopelvic control. Methodology: 30 female students with a mean age of 16.65±0.75 years, height of 161.80±4.11 cm, weight of 62.70±5.64 kg who had weak lumbopelvic control were purposively selected and randomly divided into two experimental groups n=15 and control groups n=15. The experimental group performed the neuromuscular for eight weeks, three sessions per week for 60 minutes, while the control group did not receive the intervention to assess lumbopelvic control a biofeedback device was used for jumping, static balance was used for stork test, dynamic balance was used for Y test, landing error was used for landing Error Scoring System Test, and lower limb motor function was used for tests (single-leg jump test, triple jump test, 6 - meter jump test in time, and cross jump test results: The present study showed that the effect of DNS exercises on motor performance indices 0.012, gait kinematics 0.001, and lower limb injury 0.012 was significant P<0.05.
