A 1-year follow-up of Raynaud's patients treated with behavioral therapy techniques

The purpose of this study was to assess to what degree learned control of digital temperature and vasospastic attacks can be retained by Raynaud's patients over a full year period. Subjects were 19 patients suffering from diagnosed idiopathic Raynaud's disease who had undergone behavioral training. These patients had been trained to increase digital temperature using either autogenic training, biofeedback, or a combination of autogenic training and temperature biofeedback. Results indicated that the mean number of vasospastic attacks per day occurring 1 year after training was approximately equal to the number occurring at the end of the initial training (1.2-1.3 per day). Patient satisfaction with the treatment program was above average (3.5 on a 5-point scale). The patients' ability to maintain digital temperature during the cold stress challenge was impaired, however. At 1-year follow-up, digital temperature readings taken in the laboratory were identical to baseline levels.
