A Novel Active Rehabilitation Model for Stroke Patients Using Electroencephalography Signals and Deep Learning Technology

Abstract

The main clinical manifestations of stroke are motor, language, sensory, and mental disorders. After treatment, in addition to being conscious, other symptoms will still remain in varying degrees. This is the sequelae of stroke, including numbness, facial paralysis, central paralysis, and central paralysis. If the sequelae of stroke are not treated effectively, they can easily develop into permanent sequelae. Most of the affected people have sequelae, and most of them have symptoms of upper limb paralysis. Therefore, it is of great significance to study how to carry out effective rehabilitation training for stroke patients to reduce the disease and even restore their motor function. Based on this background, this research aims to use deep learning technology to design a stroke rehabilitation model based on electroencephalography (EEG) signals. First, the patient’s EEG signal will be preprocessed. Then, an improved deep neural network model (IDNN) is used to get the EEG classification results. The traditional DNN model construction process is simple and suitable for scenarios where there is no special requirement for the data format, but the generalization of a single DNN model is usually poor. Large margin support vector machine (LM_SVM) is an extension method of support vector machine (SVM), suitable for any occasion. By optimizing the edge distribution, better generalization performance can be obtained. Taking into account the advantages of DNN and LM_SVM and the high aliasing characteristics of stroke data, an improved DNN model is proposed. Finally, based on the EEG recognition result of the model, the rehabilitation equipment is controlled to assist the patient in rehabilitation treatment. The experimental results verify the superiority of the EEG classification model used, and further prove that this research has good practical value.

Construction of Bilingual Teaching Mode Based on Digital Twinning Technology

“…Research on the application of digital twin technology in the teaching process can broaden and deepen the teaching ideas, improve and optimize students' learning mode, shift from limited empirical learning to digital learning, and avoid the adverse effects of the wrong experience on actual production and processing. e digital twin digital model can easily solve the nonlinear and uncertain factors that the traditional mechanism model cannot solve, improve the production accuracy, and ensure the product quality so that digital twin technology can form an evolving system with machine learning [17][18][19] and deep learning [20,21].…”

“…is paper presents a prediction model of the teaching and learning effect of piano collective class based on DL (Deep learning) [4][5][6] network in order to realise the accurate prediction and evaluation of piano collective class instructional effect and promote the improvement of piano collective class instructional quality. Currently, many straightforward methods are used to assess the quality of instruction in colleges and universities, including the absolute evaluation method, relative evaluation method, rating method, comment method, realistic method, and comprehensive scoring method.…”

Image Composition and Semantic Expression of Traditional Folk Art Based on Evolutionary Computing Technology

“…Semantic patterns are, simply put, patterns and mechanisms that connect form and meaning. Digital image processing, multimedia information retrieval, machine learning and deep learning technology [14], multimedia database management, and many other related technologies [15] are all used in the image composition and semantic expression of folk art using evolutionary computing technology. is is an interdisciplinary subject, and the related research is crucial to image processing technology, signal processing technology, and information processing technology theory.…”
