چکیده
در این مقاله به شبیهسازی رفتارهای بیمارگونه در گام برداشتن بیمارهای مغزی و نخاعی و تأثیر تکنیکهای توانبخشی در آنها پرداخته شدهاست. این شبیهسازیها به شکل قابلتوجهی موجب پیشرفت سطح دانش محققان در حوزهی توانبخشی عصبی درباره مبنای عصبشناختی ترمیم سامانهی عصبی بیماران مغزی و نخاعی در اثر تکنیکهای توانبخشی میشوند. با این وجود، این شبیهسازیها تاکنون بسیار محدود بودهاند و اغلب آنها به صورت موردی به مطالعهی برخی از آثار بیماریهای مغزی و نخاعی پرداختهاند. اما در این مقاله تلاش شدهاست که با وارد نمودن اثر اختلالات دادههای مغزی، رفتارهای بیماران دچار سکتهی مغزی و ضایعهی نخاعی با عمق بیشتری مورد مطالعه قرار گیرد. بدین منظور در سامانهی عصبی-عضلانی از معماری مشترک رفلکس و مولد الگوی مرکزی استفاده شدهاست، که روی دو مدل اسکلتی-عضلانی دو پا با یک بند و یک پا با دو بند پیاده شدهاست. سپس مدلهای راه رفتن فلج یکسویه و فلج پایینتنه با ایجاد اختلال در دادهی مغزی مولد الگوی مرکزی استخراج شدهاست. همچنین با استفاده از این مدلها اثر تکنیکهای توانبخشی در بیماران فلج پایینتنه بررسی شدهاند و با داده های تجربی به صورت کیفی مقایسه شدهاند، که همخوانی قابلقبولی را نشان میدهند.

چکیده [English]
In this paper the simulation of pathological behavior in gait locomotion of central nervous system (CNS) diseases and effects of rehabilitation techniques are investigated. These simulations noticeably deepen the knowledge of researches in neurorehabilitation realm about the neuroscientific basis of CNS treatment after a neural disorder. However, only a limited number of these simulations have been proposed in the previous works that issued some aspects of CNS diseases. Due to this limitation, in this paper, a more efficient simulation has been done on pathological behavior of neural disorders with including the brain signal disruption in the models. To do this, combinations of neural reflexes and central pattern generator (CPG) has been incorporated in the neuromuscular system and examined on two different msculoskeletal system containing two leg-one segment and one leg-two segment systems. Then, the locomotion of hemiplegia and paraplegia patients are simulated by inserting a malfunction in the supraspinal signal coming into the CPG. Moreover, the effects of rehabilitation effects on paraplegia patients have been investigated and qualititatively compared to the experimental data.
