چکیده

مقدمه و اهداف
کنترل پوسچر اساس عملکرد حرکات بدن بوده و وجود آن برای بسیاری از فعالیت­های ورزشی، مورد نیاز و ضروری می­باشد. عوامل متعددی می‌توانند بر میزان کارایی سیستم کنترل پوسچر تأثیر منفی گذاشته و ثبات پوسچر را کاهش دهند که در نتیجه با افزایش نوسانات پوسچر همراه خواهد بود. از جمله این عوامل، می‌توان به اختلالات اسکلتی- عضلانی مانند کمردرد اشاره نمود؛ لذا هدف تحقیق حاضر مقایسه میزان نوسان پوسچر در ورزشکاران مبتلا به کمردرد مزمن غیراختصاصی در مقایسه با ورزشکاران سالم بود.
مواد و روش ها
 میزان نوسان پوسچر 68 ورزشکار ( 34 ورزشکار مبتلا به کمردرد مزمن غیراختصاصی و 34 ورزشکار سالم) به وسیله دستگاه توزیع فشار زبریس در دو حالت ایستاده با چشمان باز و بسته مورد بررسی قرار گرفت. به منظور انجام تجزیه و تحلیل داده­های آماری و نیز مقایسه بین گروه‌ها از روش آماری تی مستقل استفاده گردید.
یافته ها
نتایج تحقیق نشان داد که در هردو وضعیت ایستاده با چشمان باز و بسته در میزان نوسان پوسچر بین ورزشکاران مبتلا به کمردرد مزمن غیراختصاصی با ورزشکاران سالم تفاوت معناداری وجود دارد (05/0P≤).
بحث و نتیجه گیری
با توجه به نتایج تحقیق حاضر، مشاهده می­شود که ورزشکاران مبتلا به کمردرد مزمن غیر­اختصاصی در مقایسه با ورزشکاران سالم مشابه از نوسان پوسچر بیشتری در  دو وضعیت ایستاده با چشمان باز و بسته برخوردار بودند که این نتایج بیانگر وجود اختلال در کنترل پوسچر این ورزشکاران می‌باشد. پیشنهاد می‌شود با اندازه­گیری نوسان پوسچر در ورزشکاران مبتلا به کمردرد مزمن غیراختصاصی به شناسایی یکی از مهم‌ترین عوامل خطرزای آسیب‌های ورزشی در این افراد اقدام نمود.

چکیده [English]

Background and Aim: Postural control is the basic part of body movement performance and is needed for many everyday activities, particularly sport activities. Several factors can adversely affect efficiency of postural control system and decrease postural stability which results in increased postural sway. Among these factors, musculoskeletal disorders such as low back pain can be mentioned. Thus the purpose of this study was to compare postural sway in athletes with nonspecific chronic low back pain and healthy athletes.
Materials and Methods: Postural sway of 68 athletes (34 nonspecific chronic low back pain and 34 healthy individuals) was examined by Zebris force distribution system in two conditions of standing with open and closed eyes. The independent t-test was used to analyze the data and compare between groups.
Results: Results showed a significant difference between athletes with nonspecific chronic low back pain and healthy ones in standing with open and closed eyes (P≤0.05).
Conclusion: According to the results of this study, athletes with nonspecific chronic low back pain showed increased postural sway in two conditions of standing with open and closed eyes in comparison with healthy athletes. Measuring postural sway of athletes with nonspecific chronic low back pain is recommended to identify one of the most important risk factors of sport injuries in these athletes.
