Measuring craniovertebral (CV) angle is one of the common objective methods in assessing head posture [4,7]. Craniovertebral Angle Shoulder Angle Forward head posture (FHP) is the forward movement of the head that is caused by improper postural awareness and often results in muscular imbalance that causes pain. The second cervical vertebra (C2) is the most important vertebrae to exam at this level since it is the vertebrae that supports the weight of the cranium and distributes forces to the rest of the cervical spine. If the angle created is less than 135, it is considered pathological. The ligaments in the spine support and reinforce the joints between the vertebrae. It can be due to a congenital, developmental, or acquired cause. The longus colli (LCo) muscle is an important muscle to control head posture. The normal value of craniovertebral angle was 50 degrees,below this degree indicates forward head posture (9) Level of upper extremity function was determined by using the Quick-DASH questionnaire.
