A 45-year-old woman with systemic lupus erythematosus presented with multiple arthralgia, coldness in fingers and toes, and Raynaud's phenomenon. Electroacupuncture (EA) therapy was performed in two courses (14 treatment sessions) 1 month apart. A needle was inserted in the proximal (or medial) side of the painful joint and another needle was inserted in the distal (or lateral) side of the same joint and a 50 Hz stimulus was applied (3 s bursts with 1 s gaps) for 15 min. A visual analogue scale was used to evaluate pain intensity. Cold provocation testing was conducted before and after EA sessions to determine the vasomotor response. Visual analogue scale scores were lower after EA sessions than before. Before starting EA, the skin temperature of the right mid fingertip was 27.9°C and that of the left mid fingertip was 28.3°C. In contrast, after the EA sessions, the skin temperature of the right mid fingertip was 34.8°C and that of the left mid fingertip was 34.7°C. In the last EA session, the patient reported that the cold in her fingers and toes had eased and Raynaud's phenomenon, in which nail colour tone changed from white to red, had disappeared. In the cold-provocation test, before EA, the temperature recovery rates of mid fingertips after cold exposure reached over 80% in 20 min. In contrast, after EA had been completed, the temperature recovery rate exceeded 80% in 10 min, thus the delay of temperature recovery was alleviated.
