15.5.1 Forward head posture vs Normal posture
Forward head posture, also called iPosture, iHunch, poking chin posture, wears neck,
computer neck, upper crossed syndrome, text neck, and dowager's hump, is the
common spinal problem of an excessively kyphotic (hunched) thoracic spine driving
neck pain and cervicogenic headache.
In a neck with perfect posture (as seen for instance in young children) the head is
balanced above the shoulders. In this position, the load on each vertebra of the
cervical spine is spread evenly between the two facets (apophyseal) joints at the back
and the intervertebral disc and vertebral body at the front.
The iHunch is characterized by a posture with vagi at the head sitting somewhat
forward of the shoulders (i.e., the ear lobe is anterior to a vertical line through the point
of the shoulder (acromion process)). This can be very marked, with the back of the
skull positioned anterior to the breastbone (sternum). The chin is poked forward.
