Pericranial Muscle Tenderness And Pressure Pain Threshold In The Temporal Region Of Migraine Patients
Published 1987 · Medicine
Material and Methods: 25 patients have beenmeasured outside of attacks and 15 of these also durina attacks. 9 healthv volunteers served as controls. The patient was fi&t seen by one inveitigator who scored muscle tenderness on a. 4'point arbitrary scale. Thereafter PPT was determined in both temporal regions of the.tupine patient by another investigator. The pressuse-algometer consi,sted.of a pressure-sensitive strain-gauge at the 0.5 cm tip of an. acrylic handle; The pressure against the temple is gradually increased with a constant loading ratc.until the patients signaled with a push button that the sensation of pressure had changed to include pain. The pressure reading at this time, read from a pen recorder, was termed the pressure-painkthreshold (PPT). Results: ‘Preliminary evaluation of the first.15 patients outside of attmdicate a lower PPT forpatients with common migraine (147 kPa), whereas patients with common migraine had a PPT of 233 kPa, very similar to the controls (244 kPa). The...tenderness score was significantly increased during attacks. Discussion: If common migraine patients in the final, larger material show a similarly low PPT eompare.d to classic migraine patients and controls, it may be of pathophysiological importance for the development of common migraine attacks.
