Based on the reviewed literature, Core Stabilization Exercises (CSEs) have been shown to have positive effects on patients with low back pain. To our knowledge, very few studies have examined the impact of CSEs on neck pain, particularly in patients with forward head posture (FHP), despite that several authors suggested that FHP may be caused by lumbopelvic malalignment.

Therefore, the purpose of the study is to assess how CSEs may affect the cervical sagittal balance parameters (CSB) in patient with FHP.

After the patient fills the consent form, the Craniovertebral angle will be measured by taking a photograph, then this photograph will be analysed by the KINOVEA software.

If the CVA is less than 50 degrees, he/she will have a lateral x-ray on the cervical spine to measure the radiographic variables of the CSB parameters. These variables will be assessed and quantified by Image J software.

The patients will be classified randomly into 2 groups, the intervention and control groups. The intervention will receive CSEs program and Postural Correction Exercises (PCEs) program, but control group will receive only PCEs program.

Both programs will be implemented for 6 weeks 3 times/ week and after 6 weeks, patients will be reassessed again to determine the difference.

Inclusion Criteria:

• CVA less than 50 degrees/ neck pain for about 4 weeks

Exclusion Criteria:

• Vertebrobasilar insufficiency/ cervical surgery/ cervical or TMJ fracture
