چکیده

هدف پژوهش حاضر، تعیین تأثیر مشاهده‌عمل و تصویرسازی‌حرکتی بر تعادل و طول، سرعت و ریتم گام سالمندان مبتلا به سکته مغزی بود. 24 نفر از سالمندان مبتلا به سکته مغزی به صورت داوطلبانه در این پژوهش شرکت کردند. از آزمون‌های لک‌لک، زمان برخاستن- راه‌رفتن و نرم‌افزار تحلیل دو بعدی کینوا استفاده شد. مرحله تمرین شامل 16 جلسه (3 جلسه در هفته و هر جلسه ، 45 دقیقه‌) بود. نتایج آزمون تحلیل واریانس مرکب نشان داد که تعادل ایستا، سرعت و طول گام نسبت به پیش آزمون پیشرفت معناداری داشتند. تصویرسازی-حرکتی و مشاهده‌عمل منجر به بهبود تعادل پویا در مقایسه با گروه کنترل شد. سرعت گام گروه تصویرسازی-حرکتی بیشتر از گروه مشاهده‌عمل و کنترل بود، در نهایت، ریتم گام در گروه مشاهده‌عمل، نسبت به پیش آزمون پیشرفت داشت. یافته‌های پژوهش پیشنهاد می‌کنند که مشاهده و تصویرسازی حرکتی می‌توانند تعادل و پارامترهای راه‌رفتن را در سالمندان مبتلا به سکته مغزی بهبود بخشند.

چکیده [English]

The purpose of present study was to determine the effects of action observation and motor imagery on balance, gait length, speed and rhythm in elderly post stroke. Twenty- four elderly post stroke participated voluntarily in the study. Stork test, Timed Up and Go test (TUG) and KINOVEA software were used in pretest and post-test. Mixed ANOVA revealed that static balance, speed and length of step improved significantly compared to pretest. Motor imagery and action observation resulted in a significant improvement in dynamic balance compared to control group. Speed step of motor imagery group was more than action observation and control group significantly and action observation group experienced significantly improvement in step rhythm compared to pretest. Finding suggested that motor imagery and action observation improves balance and gait parameters in elderly post stroke.
