Resumo
Copyright © 2017 by SCITEPRESS – Science and Technology Publications, Lda. All rights reserved.Parkinson’s Disease (PD) is a neurodegenerative disorder that affects mostly elderly people. Approximately 2% of world population, over 60 years old, lives with PD. This pathology is recognized not only by motor symptoms such as tremor, postural gait and rigidity, but also, nonmotor symptoms as depression and sleep abnormalities may be developed as well. In Brazil, according to the Ministry of Health, 200,000 people face the challenge to develop day-by-day activities due to PD. More than just a disease causing motor disturbances, PD brings to patients uncertainties about their ability to take care of themselves independently. In this context, assistive technologies assume an important position in order to bring back life quality and self-trust to PD patients. This work aims to study techniques, develop hardware and software for a better approach in tremor suppression in order to bring back life quality to PD patients. This study approaches the problem of flexion/extension carpi radialis tremor suppression using two different strategies. The first is a mechanical suppression based on a servomotor opposing to tremor movement. The second strategy is a functional electrical stimulator. Both systems are triggered by electromyogram (EMG).
