Cervicogenic headache is a chronic, hemicranial pain syndrome in which the sensation of pain originates in the cervical spine or soft tissues of the neck and is referred to the head. The trigeminocervical nucleus is a region of the upper cervical spinal cord where sensory nerve fibers in the descending tract of the trigeminal nerve converge with sensory fibers from the upper cervical roots. Thi...

Cervicogenic headache is a chronic, hemicranial pain syndrome in which the source of pain is located in the cervical spine or soft tissues of the neck but the sensation of pain is referred to the head. The trigeminocervical nucleus is a region of the upper cervical spinal cord where sensory nerve fibers in the descending tract of the trigeminal nerve converge with sensory fibers from the upper ...

OBJECTIVE To evaluate postural performance and head stabilization of patients with chronic neck pain. DESIGN A single-blind comparative group study. SUBJECTS Patients with work-related chronic neck pain (n = 9), with chronic whiplash associated disorders (n = 9) and healthy subjects (n = 16). METHODS During quiet standing in different conditions (e.g. 1 and 2 feet standing, tandem standin...

objective: to investigate the effect of intracerebroventricular injection of histamine on pain induced by subcutaneous iniection of formalin in the left ear of rabbit and the effect of the amine on morphine analgesia and naloxone hyperalgesia. design: experimental study. animals: sixty - six male new zealand white rabbits weighing 2.640.16kg. procedure: intracerebroventricular injections of the...

This review was developed as part of a debate, and takes the "pro" stance that abnormalities of structures in the neck can be a significant source of headache. The argument for this is developed from a review of the medical literature, and is made in 5 steps. It is clear that the cervical region contains many pain-sensitive structures, and that these are prone to injury. The anatomical and phys...

OBJECTIVE To report on a patient found to have injury of the spinothalamic tract on diffusion tensor tractography following traumatic brain injury. CASE DESCRIPTION A 29-year-old male patient with head trauma resulting from a pedestrian car accident presented with pain in multiple areas (both subscapular areas, posterior head and neck, both upper trapezius areas, and the right arm and leg). H...

Our recent findings have demonstrated that rodent models of closed head traumatic brain injury exhibit comprehensive evidence of progressive and enduring orofacial allodynias, a hypersensitive pain response induced by non-painful stimulation. These allodynias, tested using thermal hyperalgesia, correlated with changes in several known pain signaling receptors and molecules along the trigeminal ...

The management of pain in dentistry encompasses a number of procedural issues, including the delivery of anesthetic and the management of postprocedural pain, as well as pain diagnosis, management strategies for orofacial conditions that cause pain in the face and head, and the management of pain in special populations. Given the extensive nature of the topic, this article reviews pain definiti...
