The authors investigated the effects of EMG biofeedback training on heart rate and subjective pain ratings during the cold pressor test.The subjects were 22 preoperative surgical patients who had been admitted to the National Cancer Cencer Hospital. All of them recieved the first cold pressor test (30 sec immersion of the ice water) one week before their surgical operation and the second cold pressor test after the following conditions were fulfilled. In two of teh thre conditions, patients were given EMG biofeedback training either for decreasing (Dec-BF) or for increasing (Inc-BF) EMG activities. Remaining condition was a no-training control. In Dec-BF, patients were asked to decrease their EMG activities before the second cold pressor test, while those in Inc-BF were asked to increase their EMG activities.Significant differences in heart rate and subjective pain ratinds were obtained among the three groups during the second cold pressor test. The largest difference on heart rate during the second cold pressor test was observed between Dec-BF and either Inc-BF or Control. Patients in Dec-BF showed a significant slowdown of heart rate during the second cold pressor test. The mean ratings of pain in the second cold pressor test for Dec-BF, Inc-BF and Control were 6.29,6.88 and 7.71 respectively. Difference between Dec-BF and Control reached significance.The above results suggest a possibility of clinical application of EMG biofeedback training to the control of pain reactions.
