Treatment of Raynaud's disease with temperature biofeedback.

A 40-year-old white woman who for 15 years had had Raynaud's disease--a vascular disorder characterized by poor blood circulation and coldness in the extremities--was treated with temperature biofeedback. In treatment sessions over a 13-month period she was provided with continuous, moment-to-moment information about the rise and fall of fingertip temperature. Gradually she was able to learn to raise her peripheral temperature and to gain some volitional control over a highly complex physiologic response.
