Present study was performed to elucidate whether EMG biofeedback assisted relaxation training might have any influence on painful respiratory muscle groups and respiratopry function, especially vital capacity(VC). Among 25 subjects who were painful in respiratory muscles, 18 subfects were incorporated into this training program. Apparatus : The apparatus for EMG-BFT and Spirometry were used. Procedure : The targets were intercostal muscles & abdominal muscle groups, diaphragmatic muscle, and shoulder, neck and back muscle groups. The numbers of relaxation training ranged 3-26(mean : 9). Two of each 7 minutes muscle relaxation training were performed. Respiratory function was examined before and after each relaxation training. Paired t-test was used for statistical analysis. Results : 1) EMG level was 5.2±4.6μV before EMG-BFT, and 4.12±3.2μV after EMG-BFT (p<0.05). 2) VC was 1877.4±716.0ml bofore EMG-BFT, and 2043.7±694.2ml after EMG-BFT (p<0.001). 3) There was no relationship between the me-an decreased EMG level and the mean increasd vital capacity. 4) The quality of life was examined with Hugh-Jones criteria which was usually applied for evaluation of dyspea. The subjects became more active after EGM biofeedback relaxation (p<0.05). Summary : It was suggested that EMG level in painful respiratory muscle groups with increase of vital capacity and improvement of physical activity.
