The study investigated a relationship between the presence of active trigger points (TrPs) craniocervical posture and clinical features in patients with migraine. Patient postural assessments and radiographs were analyzed for head and neck posture. The results showed patients with migraine had active or latent TrPs in all muscles. The suboccipital, upper trapezius, SCM and temporalis muscles are the most affected. There is a relationship between the number of active TrPs and x-ray assessment particularly loss of cervical lordosis. This study also demonstrated no association between the number of active TrPs and the clinical features of migraine. However there appears to be an association with reduced lordosis and head extension.
