چکیده

سابقه و هدف: پاسچر پشت­ تابدار یکی از شایع‌ترین ناهنجاری ستون فقرات در قشر جوان جامعه است که نسبت به ناهنجاری‌های چون؛ کایفوز، لوردوز و پشت صافی به خاطر ماهیت غیرفعالش با احتمال بیشتری کمردرد و کایفوز شوئرمن را به دنبال خواهد داشت. هدف از تحقیق حاضر ارائه و مقایسه تأثیر سه روش تمرینات اصلاحی بر راستای ستون فقرات افراد مبتلابه پاسچر پشت­تابدار می‌باشد.
مواد و روش ها: تحقیق حاضر از نوع تحقیقات نیمه تجربی می‌باشد. جامعه آماری تحقیق حاضر را دانشجویان مبتلا به پشت­تابدار و آزمودنی‌های تحقیق را 52 دانشجو با میانگین سن، 17/1±61/20، وزن، 34/12±47/67 و قد، 62/6±25/172 تشکیل می‌داد که به صورت هدفمند انتخاب و به‌صورت تصادفی در سه گروه 13 نفری تجربی و یک گروه کنترل تقسیم‌بندی شده بودند. راستای ستون فقرات در سطح ساجیتال توسط شاخص‌های؛ زاویه سر به جلو، زاویه کایفوز، زاویه لوردوز، زاویه تیلت لگن خاصره و زاویه تاب اندازه‌گیری‌ شد. گروه‌های تجربی 1، 2 و 3 برای مدت‌زمان 12 هفته، هر هفته 3 جلسه و برای 40 تا 80 دقیقه در تمرینات متمرکز بر ناحیه مرکزی بدن، تمرینات متداول و تمرینات ترکیبی شرکت نمودند و گروه کنترل طی این مدت‌زمان فعالیت‌های متداول روزانه خود را انجام دادند. داده‌های جمع‌آوری‌شده با روش آماری MANCOVA در سطح معنی داری 05/0 تجزیه‌وتحلیل گردید.
یافته­ ها: یافته‌های تحقیق نشان داد که هر سه روش تمرینی تأثیر معنی‌داری بر راستای ستون فقرات افراد مبتلابه پشت تابدار دارد، اما تمرینات ترکیبی نسبت به دو روش تمرینی دیگر اثربخشی معنی‌دارتری (بر اساس اندازه اثر) بر راستای ستون فقرات آزمودنی‌های مبتلابه پشت­تابدار دارد.
نتیجه گیری: لذا با توجه به اثربخشی بهتر برنامه تمرینات اصلاحی ترکیبی بر روی راستای ستون فقرات افراد مبتلا به پشت­تابدار می‌توان این تمرینات  را جهت اصلاح این عارضه توصیه نمود.

چکیده [English]

Background & Purpose: Sway back posture is one of the most common spinal deformity in the young population. This deformity, due to its passive nature, was more likely to be associated back pain and Scheuermann kyphosis compared with the kyphosis, lordosis and flat back. The aim of the present study was to compare the effects of three corrective exercise methods on the spinal alignment of individuals with sway back posture.
Methodology: the study subjects  included 52 sway back students with the average age, 20/61 ± 1/17, weight, 67/47 ± 12/34 and Height, 172/25 ± 6/62 that were purposefully selected and randomly classified into three experimental (each group with n=13) and one control groups(n=13). Pre- and post-exercise spinal postural alignment was measured by; forward head, kyphosis, lordosis, pelvic tilt and the sway angles.  Experimental groups 1, 2 and 3 received core, routines and combined exercises for 12 weeks, three sessions per week and 40 to 80 minutes per session and control group participated in their daily routine activities. Data were analyzed by MANCOVA method at the 0.05 significant levels.
Results: The findings showed that each of the three methods of exercise has a significant effect on spinal alignment of sway back people, but a combined exercise has a significant better effectiveness than two other methods (Based on effect size).
Conclusion: So, combined corrective exercise can be recommended to correct spinal alignment of sway back, due to the better efficiency of these exercises.
