Development And Implementation Of Biological Feedback Treatment System

This thesis discusses how to combine the EMG feedback technology with thecomputer technology to design and develop a biological feedback treatment system, whichis in accordance with the principles of biomedical science.Medical workers can selectscientific treatments for patients in the rehabilitation phase.This thesis has mainly done the following works. Firstly, we design thelower computer, using ARM7processor combined with circuitry.It is used to collect andamplified the EMG signal. ARM7through the RS232to send the collected EMG signal tothe upper computer.In the communication process, the data packets and the instructionpackets are separated, and this strategy can avoid the confusion and conflict. The ARM7processor outputs electrical stimulation signal by electric circuit, and the design of electricstimulation signal is in accordance with the national standard GB/T14710-2009,YYT-1095-2007etc, to ensure the safety and effectiveness of the treatment process.Secondly, we design the upper computer by using C#language design software, so theupper computer can collect and analysis the EMG signal.After that it draws the EMGcurve in graphical. Because the upper computer controls the lower computer effectively,the treatment process should be very intuitive, flexible and humanization. So, medicalworkers may have a scientific evaluation on therapeutic effect, and master the detaileddata of patients.The design of the system combines the traditional therapy, and joins the auxiliarycomputer technology.It has been recognized in the field of rehabilitation medicine, so ithas good prospects for development.
