To the Editor.— An additional diagnosis to consider in the case of persistent shoulder pain1 is reflex sympathetic dystrophy.For such diagnosis, the following special tests are useful: bone scan (scintigraphy), which may show hyperfixation of radioactive phosphate2; repetition of roentgenography of the shoulder, which may now show localized osteopenia (Sudeck's atrophy); and thermography, either telethermography or liquid crystal contact thermography,3 which may reveal either increased or decreased cutaneous temperature at the shoulder. In 27 cases of shoulder-hand syndrome, thermography results were positive in 18 of 25 studies of the back of the shoulder and in 11 of 18 studies of the front of the shoulder.3
