[Painful thoracic spinous processes-a quantative measure of pain?].

A study was conduced in 100 migraine patients and 100 control subjects who did not suffer from headaches to test Dung's hypothesis that the number of painful spinal processes in the throacic spine can be used as a quantitative measure of the degree of pain in the patient concerned. The results show significant differences in the frequency of painful spinal processes between the two study groups. This supports Dung's hypotheses. As it is easy to determine the presence of painful spinal processes the frequency of this phenomenon, the reasons for it and its significance should be the sujbects of further examination.
