Abstract
The effects of alpha rhythm feedback training on the relief of severe pain due to neoplasm were assessed in three patients. Each patient was trained to increase the amount of alpha rhythm by providing a feedback signal (tone) regarding the occurrence of activity in their electroencephalographic record. Each patient received eight 40-min. alpha feedback trainings following a progressive relaxation. 1) Case 1,Recurrent rectal cancer, female, 47 yrs, MAS 31. Her condition was good except the complains of upper abdominal pain. 2) Case 2. Recurrent uterus cancer, female, 57 yrs, MAS 27. Her condition was poor and complained low abdominal and lower limb pain. 3) Case 3. Recurrent gastric cancer, male, 25 yrs, MAS 25. His condition was poor and complained upper abdominal and back pain. The effects of training were as follows. 1) In two patients (Case 1 and 2) the significant pain relief, the increase of alpha rhythm by 50%, and the lowest pain threshold and tolerance were obtained. 2) In one patient (Case 3) pain was not effectively diminished and no change in the pain threshold and tolerance was observed. 3) Progressive relaxation facilitated the effectiveness of alpha training.
