The effect of mobilization on cervical headaches

Headaches of cervical origin am often treated with mobilization. Mobilization of the upper cervical spine, occiput-C3, and effect on frequency, duration, and intensity of cervical headaches were studied utilizing an A-B-A single case design. Ten subjects who met the operational criteria of cervical headaches completed the study. A headache log was used to document headache frequency, duration, and intensity throughout all three phases (A-B-A). The baseline phase (A) lasted approximately 1 month, and no intervention was performed. The intervention phase (B) consisted of 9-12 treatment sessions, two times per week for 3 4 weeks. Visual analysis of data plots revealed a decrease in headache frequency, duration, and intensity from the baseline phase to the treatment phase. This improvement continued through the second A phase for frequency but leveled off for both duration and intensity. A one-way analysis of variance supported the findings from the visual analysis. In these 10 subjects, mobilization had a therapeutic effect on cervical headaches.
