Effect of Ultrasound-Guided Dry Needling Targeting Rectus Capitus Posterior Major on Individuals With Headaches

Headaches such as tension-type, migraine, and cervicogenic (neck-related) headaches are among the most common and disabling conditions worldwide. and are often associated with tight or sensitive muscles at the base of the skull, which can contribute to headaches. Dry needling involves inserting a very thin, sterile needle into tight muscle areas known as trigger points to relieve pain and muscle tension. When applied to the deep neck muscles, including those beneath the skull, dry needling may reduce headache symptoms. The suboccipital region contains important structures such as the vertebral artery, greater occipital nerve, and spinal cord, which requires precise needle placement to maintain safety. Many needling techniques used in this region have not been validated for accuracy or safety in living subjects. This study will use real-time ultrasound imaging to guide dry needling of the rectus capitis posterior major muscle and directly visualize nearby structures to minimize risk. The main goals of this research are to examine the effects of a single session of ultrasound-guided dry needling on headache symptoms and to confirm the safety, accuracy, and consistency of the proposed needling technique using ultrasound imaging.
