چکیده
پژوهش حاضر با هدف بررسی تأثیر تمرین راهبردهای قامتی بر تعادل زنان مبتلا به مولتیپل اسکلروزیس انجام شد. شرکتکنندگان این پژوهش 30 زن مبتلا به مولتیپل اسکلروزیس با میانگین سنی 03/5 ± 40/41 بودند. شرکتکنندگان به‌طور تصادفی به دو گروه تمرین و کنترل تقسیم شدند. گروه تمرین به‌مدت هشت هفته و هر هفته سه جلسه به تمرین راهبردهای قامتی متناسب با پروتکل طراحی‌شده پرداخت. گروه کنترل نیز فعالیتهای روزمرة خود را ادامه داد. برای بررسی تعادل ایستا و پویا و کارکردی شرکتکنندگان در پیشآزمون و پسآزمون، به‌ترتیب از آزمون شارپندرومبرگ، TUGو تعادل کارکردی برگ استفاده شد. نتایج آزمون تحلیل واریانس مرکب (2 * 2) نشان داد میانگین نمرات پسآزمون تعادل ایستا و پویای گروه تمرین در مقایسه با پیشآزمون کاهش یافت (0.001= p ) و این تفاوت معنادار در گروه کنترل مشاهده نشد (0.05< p ). مقایسة بین‌گروهی نشان داد بین نمرات تعادل ایستا و پویای گروه کنترل و تمرین تفاوت معنادار وجود داشت (0.001= p ).امتیازهای آزمون تعادل کارکردی گروه تمرین در پسآزمون در مقایسه با گروه کنترل افزایش معنادار یافت (0.001= p ). بین عملکرد گروه کنترل در مراحل پیشآزمون و پسآزمون تفاوت معنادار یافت نشد (0.05< p ).همچنین مقایسة بین‌گروهی نشان داد بین نمرات گروه تمرین و کنترل در آزمون تعادل کارکردی تفاوت معنادار وجود داشت (0.001= p ).نتایج نشان میدهد که هشت هفته تمرین راهبردهای قامتی به بهبود تعادل ایستا، پویا و کارکردی منجر شد. به‌نظر میرسد علت بهبود در تعادل متعاقب انجام‌شدن این تمرین‌ها، افزایش استقامت عضلانی، سازگاری عصبی-عضلانی و کاهش تنش عضلانی باشد.

چکیده [English]
The purpose of the present study was to investigate the effect of postural strategies training on the balance of women with Multiple Sclerosis. Thirty women with multiple sclerosis (mean age=41.4 ± 5.33) participated in this study. Participants were randomly divided into exercise and control groups. The training group performed practice for eight-week in accordance with the designed protocol, each week conclude three sessions. The control group continued its daily activities. To assess the balance of participants in the pre-test and post-test, functional balance test of Berg, TUG, and Sharpened Romberg test was used. The results showed that in the training group, the meantime of dynamic balance test in the post-test was significantly less than the control group (P=0.001). The dynamic balance test scores of the training group decreased in the post-test compared to the pretest (P=0.001), and the performance improved. There was no significant difference between the control group performance in the pretest and post-test stages (P>0.05). Static balance results also showed that the performance of the subjects in the training group was better than the control group (P=0.001). Also, the scores of functional balance tests in the training group were increased compared to the control group and performance improved (P=0.001). The score of functional balance test scores of the training group in the post-test was reduced to the pre-test and their performance improved. There is no difference between the control group performance in the pretest and posttest phases (P>0.05). The results revealed that eight weeks of postural strategies training improved static, dynamic, and functional balance. The reason for the improvement in the balance after this training seems to be due to an increase in muscle endurance, adaptation neuromuscular and reduction in muscle tension.
