There is a striking clinical similarity between migraine and attacks of vertebrogenic headache. The number of changes in function in the motor systém found in a group of 40 migraine patients may therefore be no mere coincidence. 13 of these patients were followed up for a longer period and the number of myofascial trigger-points (TrPs) at each control examination is given in Table 1. There is usually movement restriction in the corresponding segments or joints (1, 4). A strikingly significant number of TrPs was found in the diaphragm and the pelvic floor (2, 3).
