It is ranked second as the most common cause of death globally. The \"World Health Organization\" estimates that about 15 million people suffer a stroke annually. Most stroke survivors have gait disorders, and most patients cannot walk without assistance. Physiotherapy is crucial for stroke patients to recover and maintain their mobility, functionality, and well-being. In the last 20 years, the replacement of physiotherapists with wearable robotics has become essential due to the developing technology, the need for economic growth, and the challenging health circumstances around the world, such as the COVID-19 pandemic recently. Lower Limb Exoskeleton (LLE) represents the solution for stroke patients under such circumstances, though its performance is a critical challenge paid attention to in the industry. This challenge has motivated the researchers to investigate the application of gait rehabilitation. This review presents and discusses the developments in the control system of LLE over the last decade. It also explores the limitations, new directions, and recommendations in LLE development according to the literature.","PeriodicalId":45233,"journal":{"name":"Mechanical Engineering Journal","volume":"1 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66401011","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In a shoe upper made of warp knitting, slits are made by discontinuously knitting the weft under a uniform arrangement of the warp fiber. In this study, the shoe upper is modeled as an orthotropic hyperelastic body in which the slit density is defined as the design variable for controlling the intermediate density for the maximum and minimum slit densities. Referring to a formulation of a topology optimization problem of the density variation type, an inverse problem for finding the optimum distribution of the slit density is formulated with the objective and constraint cost functions defined by the squared error norm between the actual and ideal contact pressures and the deviation of the rate of the material with the maximum slit density from a limit value, respectively. This problem is solved in the same way as a topology optimization problem. The validity of this method is confirmed by numerical examples using a simple finite element model, which resembles the domain around the big toe.","PeriodicalId":45233,"journal":{"name":"Mechanical Engineering Journal","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135600376","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
