Forward head posture (FHP) increases extension of the atlanto-occipital joint and the upper cervical vertebrae as well as flexion of the lower cervical and upper thoracic vertebrae. Furthermore, this posture causes persistent and abnormal contraction of the suboccipital, neck, and shoulder muscles. Additionally, the muscles around the head and shoulders, including the trapezius, sternocleidomastoid, suboccipital, and temporal, are affected by FHP, which further worsens postural deformity. FHP is the most common deviation from ideal head posture and is characterized by the head projecting forward into the sagittal plane such that it is anterior to the trunk. Head in forward posture can add up to thirty pounds of abnormal leverage on the cervical spine, which pull the entire spine out of alignment, in addition, loss of the physiological lordosis could be a possible cause of pain due to muscular imbalance.
see if there is no statistical significant difference between the effects of Pilates mat versus cervical stabilization exercises on myoelectric activity of cervical muscles in young adults with forward head posture.
