چکیده

Nowadays, there is no doubt about the application of gait analysis in biomechanics especially assistive robotics such as prosthesis and exoskeletons. For these applications, Surface electromyography (sEMG) signals play an important role that can interact with users and predict their intentions. Two criteria that should be considered in every method of classification especially in human applications are accuracy and power of generalization. In this paper, the concept of one-dimensional Convolutional Neural Network (CNN) is employed to classify the gait cycle into two main sub-phases: swing and stance. Surface electromyography (sEMG) signals and Force-Sensing Resistor (FSR) data are collected from four locations of under knee muscles and sole respectively during level-ground walking. Then, these signals feed into CNN in an appropriate format. The power of prediction of this method (using only sEMG signals for gait event detection) is remarkable which is over ۹۰ percent. Consequently, the results of this research approve the theory that this method of classification has more preferences than methods that have been used in former researches.

اطلاعات بیشتر در مورد COI

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.

کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
