Answer

Behavior therapy, including temperature biofeedback and autogenic training, has been evaluated in the treatment of scleroderma-associated Raynaud phenomenon. In 1989, Freedman [84] demonstrated an improvement of finger blood flow and elevation of finger temperature with biofeedback training. A large, randomized, controlled trial, however, showed no clinical benefit with temperature biofeedback; however, this has been criticized because the patients may not have been adequately trained in the technique. [85] These researchers [85] claim that thermal biofeedback is efficacious if proper hand warming technique is used.
