DiscoTherapy - A game for upper limb motor rehabilitation based on motion capture and muscle activation
Competition "Inovações em Eletromiografia e Cinesiologia" - COBEC-SEB 2017
According to the Ministry of Health, stroke is the leading cause of death and disability in Brazil, with an annual incidence of 108 cases per 100,000 inhabitants. Among the main sequels presented by individuals who are affected by stroke, complications related to motor function are highlighted, with hemiparesis being the most common. In this context, only 50% of stroke survivors are predisposed to recovery from functional use of the affected upper extremity, which is one of the investment in improved rehabilitation techniques. In search of efficient rehabilitation protocols for post-stroke subjects, studies indicate that intensive therapies bring good results. They make use of repetitive and specific movements, however they can become monotonous and tedious and can only be performed in a clinical setting. In this way, new therapeutic approaches have been object of study, involving from recreational therapies to strategies with visual or sonorous feedback, as in games and environments of virtual reality. These games can be controlled by a controller, such as Nintendo Wii and PlayStation Move games, or by camera monitoring, such as Kinect games. Different sets of these platforms can be used for the rehabilitation of patients with varying degrees of motor impairment, as suggested by. However, in the researched literature, no studies were found that study in depth the viability and the impacts of game use in rehabilitation in general. In this sense, these aspects still need to be explored in order for these games to gain more space in the clinical setting. In this context, the use of games presents some interesting advantages, from a greater motivation of the patient, key piece in the search for good results, to the offering of immersive feedback, which tends to facilitate a cortical reorganization. However, when using games designed for recreation purposes during patient rehabilitation, little adaptability to the various situations is guaranteed. In general, such games do not allow adjustment in game settings, such as game speed and difficulty. In addition, control games are limited by requiring the patient to hold the control and press small buttons. Already the main limitation of the games of tracking by camera is in the interference of other objects and individuals in the vision of the camera, besides often they do not detect fine movements of pulse and hand, for example. Considering the limitations presented by the games used for the rehabilitation of post-stroke patients, this article presents the development of a rehabilitation dance game that is adjustable to the patient in such a way that the therapist is free to adapt it according to his need. In the game, it is possible to make a character dance according to two parameters: joint movements of the limbs and myoelectric activity of a given muscle. The first is defined by an inertial sensor containing accelerometer and three-axis gyroscope and the second by an electromyography (EMG) sensor. The therapist can perform training and calibration steps, in which it is possible to adjust the amplitude of the movements and the EMG signal that will be used as parameters for the dance steps of the character. The system in question can be used for motor rehabilitation purposes in different regions of the patient's body, but in the current work there is a greater focus on upper limbs.

Artificial Hand Prototype Using Sensors and Arduino Microcontroller
10ª Edição do 10º Congresso Latino Americano de Órgãos Artificiais e Biomateriais - COLAOB
Abstract
Upper limb prostheses are constantly evolving, but are lagging behind in performing certain motor functions, as well as not allowing the user to recover their tactile sensations. In search of a robotic hand that aims to meet the expectations of amputees in regaining senses of touch, Italian and Danish researchers from the Federal Polytechnic School of Lausanne in Switzerland have developed a bionic hand that has tactile sensors on the fingers. The present work aims to study the way the electrical signal is translated from the prosthesis to the nervous system, through the construction of an anatomical model with temperature and pressure sensors. The molding and construction of the hand was done with type II alginate paste and gypsum, which were wrapped in a thin fabric glove. The LM35 temperature sensor was attached to the index finger, and the piezoelectric tablet used as a pressure sensor in the palm of the hand. Both were connected to the Arduino microcontroller, which transmitted the signals received to the computer. The prototype was subjected to different temperatures and pressures. At the monitor was able to follow the changes, make comparisons and understand the operation of human skin receptors, Merkel's tactile corpuscles (tactile), the lamellar corpuscle of Pacini (deep pressure) and Ruffini's corpuscle (heat). The original prosthesis receives similar signals, which are translated into electrical peaks, mimicking the language of the nervous system, and then delivered to the nerves. To finalize the work, we intend to create a system where it is possible to reproduce and process the electrical peaks of the nervous system. There is also the intention to modify the anatomical model of the hand using a 3D printer, making it more mobile and articulated. The realization of the prototype made teaching anatomy and artificial organs more didactic, a great tool for students and teachers alike.
The Problem of Geometry of Discrete Molecular Distances
XVII Semana de Matemática e VII Semana de Estatística - 2017
Abstract
Distance Geometry is the study of geometry based on the concept of distance. It appears in applications where the input data consist of an incomplete set of distances, and the output is a set of points in the Euclidean space, which realizes the given distances. An important subclass of problems in Distance Geometry has its origin in an application in biochemistry. In this type of problem we have a set of incomplete input data, related to the structure of a given protein, and we want to reproduce the structure of the protein obtaining as output the complete set of data needed to achieve this goal.
Keywords: geometry, distances, proteins.
