چکیده

زمینه و هدف: والگوس زانو حین فعالیت‌های پویا می‌تواند منجر به پارگی لیگامان صلیبی قدامی شود. هدف پژوهش حاضر بررسی قدرت ایزومتریک و دامنه حرکتی مچ پا در ورزشکاران دختر دارای جابه‌جایی زانوها به سمت داخل حین اسکات و مقایسه آن با گروه کنترل بود.
روش‌بررسی: برای انجام تحقیق توصیفی-مقطعی حاضر 40 زن سالم (20 نفرکنترل، 20 نفر دارای والگوس داینامیک زانو) بدون سابقه آسیب‌دیدگی اندام تحتانی در شش ماه گذشته بصورت تصادفی و با توجه به معیارهای ورود انتخاب شدند. حداکثر قدرت ایزومتریک با استفاده از داینامومتر دستی بر حسب کیلوگرم و دامنه حرکتی فعال با استفاده از گونیامتر استاندارد پلاستیکی و بر حسب درجه اندازه‌گیری شد. برای تعیین اختلاف دامنه حرکتی و قدرت بین دو گروه از آزمون-های t مستقل و آنالیز واریانس چند متغیره استفاده شد (05/0P≤).
یافته‌ها: نتایج نشان داد گروه دارای والگوس داینامیک زانو دامنه حرکتی دورسی فلکشن کمتر (000/0p=)، دامنه حرکتی اورژن بیشتر(024/0p=) و قدرت ایزومتریک پلانتارفلکشن کمتری (000/0p=) نسبت به گروه کنترل داشتند.
نتیجه‌گیری: با توجه به نتایج حاضر، برنامه‌های مداخله‌ای با تمرکز بر قدرت و دامنه حرکتی مچ پا می‌تواند باعث بهبود کینماتیک حین فعالیت‌های پویا شود.

چکیده [English]

Background and Objectives: Knee valgus during dynamic activities can lead to anterior cruciate ligament (ACL) tear. The perpuse of this study was to investigate range of motion and isometric strength of ankle joint between gilrs who exhibit medial knee displacement during squat in compraed to control group.
Methods: This cross-sectional and descriptive study was carried out on forty healthy females (control, 20 ; dynamic knee valgus, 20) with no lower-extremity injury in the past 6 months elected randomly according to inclusion criteria. Peak isometric strength was measured in kilogeram using a hand-held dynamometer and active range of motion was measured in degrees with a goniometer. Independent t- test and Multi-variate analyses of variance were used to determine differences in strength and range of motion between groups (P≤0.05).
Results: The reasults showed dynamic valgus group had the less dorsiflexion range of motion (P=0.000), increased eversion range of motion (P=0.024) and less plantarflexion strength (P=0.000) in compraed to control group.
Conclusion: According to present results interventions focusing on improving strength and range of motion of the ankle may improve kinematics during dynamic activities.
