مقدمه

هدف از پژوهش حاضر، ارزیابی اثر تمرین تصویرسازی حرکتی پس از جلسۀ تمرین بر تحکیم حافظۀ حرکتی سالمندان بود.

مواد و روش­ها

جامعه آماری پژوهش، سالمندان زن و مرد سالم ساکن در آسایشگاه‌های شهر مشهد بودند که 22 نفر از افراد واجد شرایط به صورت تصادفی در 2 گروه تصویرسازی حرکتی و کنترل (11 نفر هر گروه) قرار گرفتند. مداخلات درگروه آزمون شامل مراحل اکتساب، بازیابی پس از 24 ساعت و یک هفته بود. تکلیف حافظۀ حرکتی شامل اجرای یک توالی انگشتی بود که پس از آن تمرین مکمل تصویرسازی حرکتی برای گروه تجربی و مطالعه کتاب به مدت 15 دقیقه برای گروه کنترل اجرا شد. در توصیف آماری داده‌ها از شاخص‌های میاتگین و انحراف استاندارد و در تجزیه و تحلیل داده‌ها از تحلیل واریانس با اندازه‌های تکراری (تعیین اثر بخشی تمرینات تصویرسازی حرکتی) و نیز از آزمون تعقیبی بونفرونی جهت مشخص شدن تفاوت معنی‌دار در مراحل مختلف استفاده شد و جهت مقایسه دو گروه از آزمون تحلیل کوواریانس استفاده گردید.

یافته­ها

نتایج تحقیق حاضر نشان داد که در مرحله یادداری 2، بین دو گروه تصویرسازی حرکتی و کنترل تفاوت معنی‌دار آماری با برتری گروه تصویرسازی وجود دارد (F=9/87 و P=0/005).

نتیجه­گیری

نتایج پژوهش حاضر نشان داد که استفاده از تمرین تصویرسازی حرکتی موجب بهبود معنادار در مراحل مختلف شد؛ همچنین، تمرین مکمل تصویرسازی حرکتی در تحکیم و بهبود حافظه حرکتی سالمندان پس از یک هفته موثر است.

Introduction

The purpose of the present study was to assess the effect of motor imagery training after exercise on motor memory consolidation in the elderly.

Materials and Methods

The statistical population of the study consisted of healthy men and women in Mashhad nursing homes 22 persons were randomly assigned to 2 groups: motor imagery and control (each group included 11 participants). Interventions in experimental groups include acquisition, retention after 24 hours, and retention after one week(retention 2). Motor memory task included performing a finger sequence, after which a complete simulation Supplement practice of motor imagery for the experimental group and a book study was performed for the control group for 15 minutes. Statistical analysis was an analysis of variance with repeated measures (to determine the effectiveness of motor imaging practice) as well as Bonferroni's post hoc test to identify significant improvement and covariance analysis test to compare two groups (motor imagery and control).

Results

The results of this study showed that there is a significant difference between the two groups in retention 2 (F = 87.9, P = 0.005), and motor imagery protracted further gains in performance rather than the control group.

Conclusion

The results showed that the use of motor imagery practice as supplemental practice made significant improvements in different stages. Also, the results showed that motor imagery training is effective in improving motor memory consolidation in the elderly after one week.
