Previous studies suggest that trigger points (TrPs) contribute to migraine pain, but no data is available on the effects of TrPs pressure pain sensitivity. Our objective was investigate association between number and widespread hypersensitivity in women with episodic migraines.Ninety-five migraines participated. Clinical features migraines, is, intensity, duration, frequency, onset, were collected. Active latent bilaterally explored temporalis, masseter, suboccipital, sternocleidomastoid, upper trapezius, splenius capitis musculature. Pressure thresholds (PPTs) assessed over trigeminal area (i.e., temporalis muscle), extratrigeminal C5/C6 zygapophyseal joint), a distant pain-free point tibialis anterior muscle).Active trapezius muscles most prevalent. The active not significantly negatively associated PPTs: higher TrPs, lower PPT more generalized sensitization.This study found head neck shoulder suggesting potential contribution as contributors for sensitization processes migraines.
