Biofeedback eletromiográfico assistido eletricamente por corrente FES

Abstract

Technological innovations are considered as fundamental means of provided advances in current therapy. Electromyography surface-EMG's is defined as a technique that promotes the detection and analysis of electromyographic signals picked up by the noticeable contraction of skeletal muscles or not. The SENIAM protocol for placement of electrodes in electromyography has been corroborated by studies that evaluated the electromyographic activity of the knee extensors mainly indicate that must be followed to obtain the best muscle responses. The EMG-BFB-EMG biofeedback is a learning technique defined as a physiological event monitoring process. They pick up the electrical signal of the working muscles in microvolts (uV), and transfers it to a display that is displayed by the patient in the form of signs called electromyographic amplitude. Functional electrical stimulation (Functional Electrical Stimulation - FES), can be defined as a transcutaneous electrical stimulation technique of motor neurons, with characteristics similar to the physiological and in order to produce muscle contraction, they are used in clinical practice for muscle strengthening, as well as the recovery and functional preservation of weakened muscles. If justifying the need to pursue technological innovations that contribute to improving the efficiency and reducing health procedures costs, this research aimed to unite in an intervention method the BFB-EMG technologies with the assistance of FES current and, then conceived in one box, the synergy between them. The test proposed by this research assessed the BFB-EMG in a group of 10 volunteers, control group and also evaluated the BFB-EMG with current assistance FES other 10 volunteers, the intervention group, the research followed all ethical criteria and approves the committee ethics in research with human beings of UEPB, data collection was held at SESI-PB and equipment developed in the laboratory of researchers. All statistical tests projections showed relevance and alternative hypotheses different from zero, with differences between the most favorable medium for the intervention group made use of EMG-BFB with the current FES assistance for muscle recruitment. The team devised a device that united the EMG BFB-technologies with the current FES, which is in the final testing phase, with good response and functionality. More elaborate research needs to be encouraged to build this methodological and technological innovation for physiotherapy as to combine the two technologies the new method needs to be thoroughly tested and proven by the scientific community.
