 Epidemiological studies have shown that bad posture and poor body control occurs at puberty, with forward head posture FHP and rounded shoulders being the most common biomechanical deviations in sagittal plane. The FHP is defined as an anterior displacement of the head with hyperextension of the cervical spine and this is associated with a reduction in the length of the upper portion of the trapezius, posterior portion of the cervical extensor muscles, the sternocleidomastoid and the levator scapulae. FHP can be evaluated by measuring craniovertebral angle CVA which is defined as the angle between a horizontal line passing through C7 and a line extending from the tragus of the ear to C7.
