چکیده
مقدمه و اهداف کایفوز یکی از ناهنجاریهای شایع ستون فقرات به خصوص در دختران نوجوان است و روشهای اصلاحی که برای اصلاح این ناهنجاری در سنین کودکی و نوجوانی اعمال میشود، محدود میباشد و یا اینکه سازگار با این افراد نمیباشد. هدف از تحقیق حاضر بررسی تاثیر هشت هفته بازیهای اصلاحی بر میزان انحنای کایفوز دختران نوجوان است. مواد و روشها مطالعهی حاضر از نوع نیمه تجربی است و بر روی 20 دانش آموز دختر 13 تا 17 ساله (با میانگین سنی 3/1±4/14، قد 8/4±8/159، وزن 6/7±3/48 و BMI 5/2±8/18) با ناهنجاری کایفوز وضعیتی (زاویه ناهنجاری بزرگتر از 40 درجه) صورت گرفت که بهطور تصادفی و مساوی به دو گروه کنترل و تجربی تقسیم شدند. برنامه تمرینی گروه تجربی شامل 80-60 دقیقه تمرین, سه جلسه در هفته به مدت هشت هفته بود و اندازهگیری انحنای کایفوز قبل و بعد از برنامه تمرینی با استفاده از خطکش منعطف انجام شد. در تحقیق حاضر از آزمون t زوجی برای بررسی تفاوتهای درونگروهی و از آزمون تحلیل کوواریانس برای بررسی تفاوتهای بین گروهی در سطح معناداری 05/0 استفاده شد. یافته ها تجزیه و تحلیل اطلاعات نشان داد که بین گروه کنترل و تجربی تفاوت معناداری در میزان انحنای کایفوز وجود دارد (03/0p=). همچنین میزان انحنا در گروه تجربی بهطور معناداری به میزان 5/5 درجه کاهش یافت (004/0 P=) ولی در گروه کنترل اختلاف معناداری مشاهده نگردید (56/0P=). نتیجه گیری تحقیق حاضر نشان داد که بازیهای اصلاحی تاثیر مثبتی بر میزان انحنای کایفوز در دختران نوجوان دارد. بنابراین میتوان انجام این تمرینات را به این گروه از افراد برای بهبود انحنای پشتی توصیه نمود.

چکیده [English]
Background and Aim: Kyphosis is one of the most common abnormalities of spinal cord, especially in teenager girls and corrective methods that are used to correct this abnormality in childhood and teen years are limited, or they are not adaptable with these people. The aim of the present study was to investigate the effect of eight weeks of corrective exercise on the kyphosis curvature in teenager girls. Materials and Methods: The present semi-experimental study was conducted on 20 students aged between 13 to 17 years (mean age: 14/4±1/3, mean height 159/8±4/8, mean weight 48/3±7/6, and BMI 18/8±2/5) with functional kyphosis (the angle more than 40 degrees). The participants were randomly divided into two groups: control group (n = 10) and experimental group (n=10). The exercise plan included 80-60 minutes training, 3 sessions per week for 8 weeks and kyphosis curvature measurements were performed prior to and after the training program using flexible ruler. The paired sample t-test and covariate were run to find the difference at significant level of 0/05. Results: The results showed that there was a significant difference in curvature kyphosis between the control and experimental groups (P= 0.03). Also there was a significant decrease in the curvature degree in experimental group (P= 0.004), but no significant difference was observed in the control group (P= 0/56). Conclusion: The present study indicated that the corrective exercise is a convenient and easy approach to improve functional kyphosis curvature. These exercises are recommended to this group of people to improve the curvature of their back.
