The Study Of The Relaxative Skill Training Instrument Based On Biofeedback

As the development and progress of the society, human beings are burdened with greater and greater pressure in the fields of working, studying, and living. A series of psychological diseases, which are thus triggered, are replacing the traditional physical diseases, and becoming the main factors to threaten human beings' health. Relaxing skill training instrument, which is based upon biofeedback, is invented on the above mentioned social background.By researching and investigating in related fields, a design of an instrument for multi-psychological relaxing skill training has been proposed in this paper. It is an instrument that is based upon biofeedback technology. It also combines with the traditional relaxing skill method, and makes good use of electrical and digital signal processing technology in the field of modern biomedicine. It has been proved through experimentation that this instrument will enable people to control and modulate their physical functions by training. Thus, the purpose of relaxing both psychologically and physically to cure psychological diseases will be fulfilled.The researching content of this paper mainly includes:1. the features of biofeedback technology, and the reasonableness of its application in psychological skill relaxing training.2. the introduction of self-adapting filter and RLS arithmetic, and their application in removing the signal noise and in picking up EMG in different frequency.3. the acquisition of feature value and evaluation method according to different body signals.4. the design of a multi-collecting system for biomedical signals.5. experimental design, research and result based upon biofeedback relaxing training method.This paper has prompted a new idea about biofeedback relaxing training method. It also gives a new look on the collection, analysis, and evaluation of body signals. This method together with the experimental researching result has provided valuable reference for the same kind of researching subject that may be done in the future. Therefore, it has a great value both in theory and practice.
