Craniovertebral angle
Introduction[edit | edit source]
The craniovertebral angle is identified as the intersection of a horizontal line passing through the C7 spinous process and a line joining the midpoint of the tragus of the ear to the skin overlying the C7 spinous process[1].Measurement of cranio vertebral angle, (CVA) is one of the common methods in assessing head posture.
Craniovertebral angle is also referred to as cervical angle and forward head angle.[2]
Clinically Relevant Anatomy[edit | edit source]
Craniovertebral Angle and Neck Pain[edit | edit source]
Forward head posture is characterized as pathologic when the craniovertebral angle (CVA) is ≥50° (even though such cutoffs lack rigorous validity). The greater the CVA the more the head is forward relative to the neck.[2]
In a study conducted by Kim et al, it was reported that forward head posture measurement according CVA can be used as a significant index in determining the resulting functional disability of the neck.[3]
