Publicación Acceso abierto Methodology for muscle recovery, through motor imagery techniques applying virtual reality(Institute of Physics, 2022) Ovalle, Christian; Cordova-Buiza, Franklin; Linares, Oscar; Auccahuasi, Aly; Romero Echevarría, Martha; Meza, Sandra; Urbano, Kitty; Barrera Loza, Ana; Figueroa Revilla, Jorge; Bernardo, Grisi“Recovery of movement is a long and hard process for patients. One of the most common problems that occurs is the so-called ““phantom limb““, which induces the body to feel strange due to the failure to use the injured limb. This process is due to the lack of use of the leg that in most cases is fractured and the long recovery time, so the use of crutches makes the body in conjunction with the brain understand that normal movement of the body is with the leg suspended and always with the help of crutches. In the present work a technique for the retraining of the brain is presented by means of which the brain is taught through the presentation of images if it corresponds to the right and left side of the arms and legs. This retraining makes it possible for the brain to understand the coordinated movement between the arms and legs. In addition to the use of virtual reality, through the OCULUS GEST II lenses, allowing maximum concentration, the results allow to improve the recovery time of patients, the technique can be used both in rehabilitation centers and in the patient's own home patient.“Publicación Acceso abierto “Methodology for the multichannel recording of upper limb muscle activity “(Institute of Physics, 2022) Ovalle, Christian; Cordova-Buiza, Franklin; Herrera, Lucas; Auccahuasi, Aly; Romero Echevarría, Martha; Rojas, Karin; Urbano, Kitty; Barrera Loza, Ana; Figueroa Revilla, Jorge; Herrera Salazar, José Luis“In the study of the functioning of the muscle, the study standard is to be able to analyze its behavior or functioning, this behavior is represented by a continuous signal where the muscle signal can be recorded and visualized, to perform this registration a designed circuit is required For the capture of electromyography signals, there are many options of these circuits in the market, depending on the application, the part of the body that is required to be analyzed, the best option can be chosen, in this work, we present a methodology for recording in Simultaneous 8 signals, for the characteristic use of the arm muscles, due to its special shape, which allows it to be placed in the form of a bracelet, the signals that are acquired simultaneously and individually, can be used in many applications depending on the problem and challenge, recommending for use on the arm and providing a clean signal allowing Being used in the design of detection mechanisms for some pathologies related to the arm muscles and in the design of control mechanisms for the design of prostheses. “
