Augmented Reality (AR) and Virtual Reality (VR) are emerging technologies that have increased their implementation in research. This has allowed the construction of interactive systems that have become part of modern teaching methodologies. The use of these technologies for the development of training systems provides opportunities for improvement in teaching environments, especially for children with Autism Spectrum Disorder (ASD). They require special education due to their different abilities. Previous research has developed learning systems for children with ASD with different approaches and methodologies. Thus, the present article provides a detailed review of AR/VR educational systems oriented to children with autism. We obtained 24 research papers on the topic from 2017 to 2022, which shows a lack of research works in AR and VR for special education of people with ASD.

Exoskeletons have been around since 1890 when a passive device was developed to assist movement. Although the exoskeleton initially focused on the whole body, it has become increasingly focused on a more specific area, which makes rehabilitation work more feasible and, consequently, less costly. Therefore, the purpose of the article is to present a systematic review of trends in the technical area of knee and ankle exoskeletons for rehabilitation purposes. The objective is to provide the interested researcher with a structured matrix that integrates essential components and mechanisms in the development of knee and ankle exoskeletons. As a methodology, specialized databases in biomechanics were used that aided in the collection of research conducted between 2019 and 2022. The filtering process resulted in the selection of 37 investigations. Finally, it was concluded that innovations in e...

In recent years, the development of prosthetic limbs has increased due to the various studies that have been carried out around Biomechanics. These technological advances have allowed many amputee patients to return to their daily activities and, in some cases, to recover their social life. However, there are still limitations for some types of prostheses such as passive prostheses, mainly those intended for people with transtibial amputations since they do not perform the physiological function of the joints. Therefore, in-depth research on transtibial prostheses has been carried out. The search period spans from the year 2018 to the year 2021. Information was considered in a simplified and well-structured manner on the design of a transtibial electromechanical prosthesis. Therefore, we will analyze its main features related to its design and application in the patient.
