Biofeedback treatment of Raynaud's disease and phenomenon.
Six Raynaud's disease and four Raynaud's phenomenon patients were treated with 12 sessions of finger temperature biofeedback. The mean frequency of vasospastic attacks was reduced to 7.5% of that reported during the pretreatment baseline and was maintained for a 1 year follow-up period. Significant control of digital temperature was demonstrated during laboratory training sessions. Raynaud's phenomenon patients showed significantly greater temperature increases during feedback periods than Raynaud's disease patients. Correlations between finger temperature and other physiological measures suggested that results could not be attributed to general physical relaxation. The role of imagery in self-control of digital temperature is considered.
