چکیده
زمینهوهدف: ثبات پاسچرال، به معنی توانایی بدن در حفظ مرکز ثقل در محدوده ثبات است. بازیکنان فوتبال به یک ثبات عملکردی قاب لاطمینان وابسته هستند، بنابراین آسیب های مچ ممکن است باعث یک وقفه در بازی حرفه ای بازیکنان فوتبال شود. هدف ار پژوهش حاضر مقایسه ثبات پاسچرال بازیکنان فوتبال با آسیب مزمن مچ پا در آزمون عملکردی پرش- فرود بود. روشتحقیق: 28 بازیکنان فوتبال شامل 14 فرد با بی ثباتی مچ پا و 14فرد سالم در پژوهش شرکت کردند. برای بررسی ثبات پاسچرال و اندازه گیری متغیرهای زمان رسیدن به ثبات(TTS) و جابجایی مرکز فشار (COP)، آزمودنی ها فعالیت عملکردی پرش- فرود را بر روی صفحه نیرو انجام دادند.ارزیابی آسیب مچ پا به دو صورت، پرسش از خود فرد و پرسشنامه انجام گردید. برای تجزیه و تحلیل آماری از آزمون t مستقل در سطح معنی داری 05/pیافتهها: نتایج نشان داد که در پرش رو به جلو، متغیر COP در جهت داخلی- خارجی (002/p=0) و قدامی- خلفی (01/p=0) و همچنین در پرش جانبی، متغیر COPدر جهت داخلی- خارجی (008/p=0) و قدامی- خلفی (02/p=0) بین بازیکنان فوتبال با و بدون بی ثباتی مزمن مچ پا، تفاوت معنی داری دارد؛ به گونه ای که COP در بازیکنان با بی ثباتی بیشتر از بازیکنان سالم بود. در حالی که زمان رسیدن به ثبات در بازیکنان با بی ثباتی و بازیکنان سالم بسیار نزدیک به یکدیگر بود، و در متغیر TTS تفاوت معنی داری بین دو گروه وجود نداشت ( 05/p<0). نتیجهگیری: با توجه به نقش اساسی رباط های داخلی- خارجی مچ پا در ثبات پا، به نظر می رسد که آسیب این ناحیه در تغییرات مرکز فشار اثر می گذارد و بازیکنان فوتبال با آسیب بی ثباتی مزمن مچ پا، تغییرات بیشتری در مرکز فشار نسبت به بازیکنان سالم دارند. با توجه به نقش حس عمقی در کنترل پاسچر، ورزشکاران مبتا به آسیب دیدگی مچ پا می توانند با انجام تمرینات حس عمقی و افزایش قدرت اندام تحتانی خود تا حد زیادی نقایص ثبات و تعادل خود را برطرف کنند.

چکیده [English]
Background and Aim: Postural stability is defined as body’s ability to maintain the center of gravity in the range of stability. Soccer players needs to have stable and reliable performance, therefore ankle injuries may cause an interruption in performance of professional soccer players. The aim of this study was to compare the postural stability of soccer players with and without chronic ankle instability during the jump-landing functional test. Material and Methods: 28 soccer players include 14 people with chronic ankle instability (CAI) and 14 healthy people participated in study. Time to stabilization (TTS) and center of pressure (COP) of jump-landing functional test were measured by force plate device. Ankle injury was assessed by self reporting and also standard questionnaire. Independent sample t-test was used to analyze the collected data at significant level of p <0.05. Result: The findings showed that there was significant difference in the COP of sagittal plane jump-landing in medial-lateral (p= 0.002) and anterior-posterior (p= 0.01) directions and it was the same for frontal plane jump-landing in media-lateral (p= 0.008) and anterior-posterior (p= 0.02) directions between players with and without chronic ankle injury. In other words, the COP in players with chronic ankle injury was significantly greater than healthy players, but TTS was very close to each other in two groups (p <0.05). Conclusion: In attention to the importance role of media-lateral ankle ligaments in postural stability, it seems that the injury of these ligaments could affect in COP displacement, and also postural stability factors. Soccer players with chronic ankle instability had more COP changes than healthy players. According to the role of proprioception in postural control, recommended that athletes with ankle injury contributed defects your stability and balance with practice proprioception training to increase the strength of the lower limb.
