Background:
The aim of this review is to synthesize the existing knowledge regarding headaches attributed to external physical stimuli, as classified by the ICHD-3 (Group 4.6). Two forms can be distinguished in this group: (1) headache attributed to external compression and (2) headache attributed to external traction.
Methods:
A comprehensive literature review was conducted using the Medline (PubMed) database and other relevant academic sources. All English-language articles were subjected to a relevance assessment.
Results:
The prevalence of the two types of headache varies considerably, with a higher incidence observed in women or in the presence of predisposing factors (e.g., work with compulsory helmets or long hair). An external-compression headache is typically described as a pressing sensation, whereas an external-traction headache is characterized by a sensation of pulling. The headaches typically persist for less than an hour after the stimulus has ceased, and the intensity is typically reported as mild to moderate. Apart from avoiding the trigger, which is not always possible, effective therapies have not been established.
Conclusion:
Both types of headaches are relatively common, yet they remain underrepresented in the scientific literature. Furthermore, there is a dearth of comprehensive overviews. If the triggering factor cannot be eliminated, both types of headaches can interfere with daily living and working.

The bilateral sternocleidomastoid, or SCM, and the suprahyoid and infrahyoid muscles are significant head flexors. The SCM muscles originate at the sternum and clavicle and attach to the mastoid process of the temporal bone. The SCM contracts bilaterally to bend the head forward, whereas...

01:14Cranial Bones: Superior and Posterior View
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...
