چکیده

مقدمه و اهداف
افزایش سن با کاهش پیچیدگی در سیستم های بیولوژیکی از جمله سیستم کنترل پاسچرال همراه است. سیستم سوماتوسنسوری نقش مهمی در پیچیدگی این سیستم دارد که با افزایش سن از قابلیت اطمینان ورودی های این سیستم کاسته می شود. بنابراین مداخلاتی که با افزایش ورودی های حسی، پیچیدگی فیزیولوژیکی سیستم کنترل پاسچرال را افزایش دهد؛ می تواند باعث افزایش عملکرد تعادلی و کاهش خطر افتادن شود.
 مواد و روش ها
در این مطالعه 8 فرد سالمند با سابقه افتادن با متوسط سنی (53/3±) 25/66  سال به روش نمونه گیری غیر احتمالی ساده انتخاب شدند و پیچیدگی نوسانات مرکز فشار آنان در وضعیت های مختلف با و بدون کفی و با چشم باز و بسته با استفاده از متغیر آنتروپی تقریبی اندازه گیری شد.
 یافته ها
استفاده از کفی بافت دار افزایش معناداری در مقدار آنتروپی تقریبی در جهت داخلی-خارجی در سالمندان با سابقه افتادن ایجاد کرد. آنالیز Post-hoc بین آنتروپی تقریبی داخلی- خارجی شرایط مختلف وضعیتی نشان داد که پارامتر آنتروپی تقریبی داخلی- خارجی افزایش معناداری را در وضعیت چشم بسته با کفی نسبت به وضعیت چشم بسته بدون کفی داشته است (004/0=P). این پارامتر در وضعیت چشم بسته با کفی نسبت به وضعیت چشم باز بدون کفی نیز افزایش معناداری داشت (001/0=P).
 نتیجه گیری
از آنجایی که استفاده از کفی بافت دار پیچیدگی نوسانات پاسچرال را افزایش داد، می تواند در سالمندان با سابقه افتادن به عنوان یک مداخله تعادلی جهت کاهش خطر افتادن استفاده شود.

چکیده [English]

Background and Aim: Aging is associated with reduction in the complexity of biological systems such as postural control system. Somatosensory system plays an important role in the complexity of the postural control system which its inputs reliability is reduced with age. Therefore, the interventions that improve complexity of postural control system by increasing sensory input can improve balance performance and reduce risk of falling.
Materials and Methods: In this study 8 faller older adults with the average age of 66.25 (±3.53) years were selected by simple non-probability sampling method. The complexity of the center of pressure (COP) sway was measured by approximate entropy in medial-lateral and anterior-posterior directions in different conditions: using textured insole [with and without textured insole] with open and closed eyes.
Results: Textured insole significantly improved medial-lateral approximate entropy values in faller older adults. The post-hoc analysis of medial-lateral approximate entropy of different postural conditions showed the approximate entropy in eyes closed with textured insole condition increased significantly compared with  eyes closed without textured insole condition (p=0.004). This parameter also increased significantly (p=0.001) in eyes closed with textured insole condition compared with eyes open without textured insole condition.
Conclusion: Since textured insole increased complexity of postural sway, it can be used as an intervention which may reduce the risk of falling in older adults with a history of falling.
