Affective Regulation On The Rehabilitation Of Stroke Patients Based On Physiological Signal

After the central nervous system coloboma caused by brain damage defects, stroke patients lost the function of dominating their bodies. Traditional rehabilitation is to train the patients’muscles and joints under the guide of doctors, so as to improve the strength of muscles and restore the motor function of joint. For the stroke patients are commonly depressed, lonely and irritable, they may easily generate negative emotions during the rehabilitation process. Traditional rehabilitation merely aims to help patients physical function recovery, and ignore the impact on rehabilitation by emotion. Affective regulation should be added to the stroke rehabilitation in order to make patients exercise with high intrinsic motivation, then the treatment effect will be improved.The ultimate goal of this thesis is to make the stroke patients have a high intrinsic motivation to do rehabilitation exercise. The specific objectives include (1) establish a kind of personalized emotional model based on physiological signals, (2) design intervention projects and an intelligent interface which are combined to regulate the emotion of subjects, (3) develop a test-bed to verify the effectiveness of affective regulation.The study has concluded that (1) character or personality has an impact on emotion, so different intervention material should be applied to different subjects. (2) as a means of intervention projects, music can effectively adjust the negative emotions of the subjects, and the rate of regulation among three types of negative emotions (Fatigue, Frustrating and Denial) are 8.49%,13.79% and 16.76%, respectively. (3) music intervention is proved to improve the intrinsic motivation of the subjects, and the change rate of interest/enjoyment is 15.88%.The main contributions of this thesis are (1) considering the impact of character into emotional model which is established based on physiological signal to identify the emotional state of the subjects, (2) adding affective regulation to the traditional stroke rehabilitation process, and proving music intervention can improve the intrinsic motivation of the subjects through experiment.
