영문 초록

A pilot study was done to investigate the biofeedback aided relaxation of frontalis muscle in normal subjects. The subjects were devided into Group A (N = 5,session =5, feedback modality= visual) and Group B ( N = 11, session =10, feedback modality= auditory), then baseline, false feedback and biofeedback were practiced every session to compare each other type of experiments. The experiment was carried by repetitive measure. The results were as follows; 1. Mean muscle potential was 2.28uv and 2.27 uv in Group A and Group B respectively, which were lower than those of other studies. 2. Group A showed statistically significant differece among different types of experiments, but Group B showed statistically significant difference among both types of experiments and session. There was no significant interaction between experiments and sessions in the former, but significant interaction was found in the later. 3. Comparing each other by types of experiments, significant difference was found between biofeedback and false feedback. The former had more relaxation effect than the later. 4. Comparing mean muscle potentials between biofeedback and false feedback by sessions, biofeedback aided relaxation effect was considered to be derived by specific effect rather than nonspecific effect, and the effect was thought to be more increased as the number of session increased. 5. Comparing mean muscle potentials of Group A and Group B by same type experiment, there was a significant difference in biofeedbacks but not in both baselines and false feedbacks
