چکیده

مولتیپل اسکلروزیس یک بیماری مخرب میلین در قسمت‌های مختلف سیستم عصبی مرکزی از جمله سیستم حسی ـ حرکتی است که باعث اختلال تعادل در بیماران می‌شود. دراین‌راستا، هدف از پژوهش حاضر بررسی اثر بار شناختی تکلیف بر نوسانات قامتی بیماران مولتیپل اسکلروزیس نسبت به افراد سالم بود. بدین‌‌منظور، ۲۰ بیمار مبتلا به مولتیپل اسکلروزیس از انجمن ام‌.اس ایران (با دامنۀ سنی ۵۹/۱۲±۸۵/۴۱ سال و نمرۀ مقیاس پیشرفت ناتوانی ۵ـ۰) و ۲۰ فرد سالم (با دامنۀ سنی ۶/۸±۵۲/۴۶ سال) به‌صورت داوطلبانه در این پژوهش شرکت نمودند. آزمودنی‌ها سه تکلیف شناختی مختلف را بر روی دستگاه تعادل‌سنج ایستا اجرا کردند ومساحت نوسانات قامتی آزمودنی‌ها با دستگاه تعادل‌سنج ایستا اندازه‌گیری شد. برای تحلیل نتایج نیز از آزمون تحلیل واریانس با اندازه‌گیری‌های مکرر ((P≤0.05استفاده گردید. یافته‌ها نشان می‌دهد که تکلیف شناختی اثر معناداری بر افزایش مساحت نوسانات (P=0.001) در هر دو گروه داشته است و بین میانگین نوسانات قامتی در تمامی سطوح در دو گروه بیماران مبتلا به ام‌.اس و سالم تفاوت معناداری وجود دارد ((P≤0.05. نتایج بیانگر آن است که نوسانات قامتی در بیماران مولتیپل اسکلروزیس هنگام اجرای تکلیف شناختی نسبت به افراد سالم افزایش بیشتری داشته ‌است.

چکیده [English]

Multiple sclerosis is a demyelinating disease that due to the involvement of multiple areas in central nercous system, including sensorimotor system can impair the patients,balance. Purpose of this study was to evaluate the effect of cognitive task on postural sway in multiple sclerosis patients. Twenty volunteer men and women with multiple sclerosis (mean ±SD age: 41.85± 12.59 years old and EDSS score 0-5) from Tehran multiple sclerosis association and twenty healthy adults (mean ±SD age: 46.52± 8/6 years old) were participated in this study and area of postural sway measured in 3 different level by static stabilometer. Repeated measurment test were used for statistical analysis (P<0.005). area under the curve increased by cognitive task in multiple sclerosis and control groups (P=0.000) and there was a significant difference between two groups for area under the curve (P<0.005). The results of this study showed that performance cognitive task increased (%22, %35, %49) of center of pressure sway in multiple sclerosis patients. Also, there was a significant difference between postural sway two groups in all level of cognitive task.
