This study was performed to examine the effect of muscle relaxation training on patients with insomnia complaints. The subjects were selected those who have taken poor sleep below 240-300 minutes per day, between 16~15ages, without organic brain syndroms. Using the Budzinski's muscle relaxation training tapes the patients have been gotten the muscle relaxation training daily during four weeks and examined the state anxiety with Spielberger's Trait-State Anxiety Scale, and investigated Sleep amounts, Blood pressure, Pulse rates, Respiratory rates before and after the muscle relaxation training. The results were as follow ; 1. The mean of the State anxiety after the muscle relaxation training(41.8+/-6.4) was significantly lower than that of before training (54.2+/-7.0) (p<0.001). 2. The mean of systolic blood pressure after the training (114.3+/-7.8mmHg) was significantly lower than that of before training (139.0+/-9.8) (p<0.001). 3. The mean of Pulse rate after the traing (89.2+/-3.0) was significantly lower: than that of before training (103.9+/-7.4) (p<0.001). 4. The mean of Respiratory rate after the training (18.6+/-1.0) was significantly lower than that of before training (22.8+/-1.3) (p< 0.001). 5. The mean of Sleep amount after the muscle relaxation training (459.8+/-52.4 minutes) was significantly increased than that of before training (287.3+/-30.3) (p<0.001).
