Physical therapy agents and deep cervical flexor muscle training will be applied to the patients. These will be administered a combination of transcutaneous electrical nerve stimulation, ultrasound, a hot pack, and muscle training 3 times a week for 4 weeks by the physical therapist. Training of the craniocervical flexor muscles is going to be focused on the deep flexor muscles such as longus capitis and longus colli muscles, making neck flexion, not the head.

Physical therapy agents and core stabilization training will be applied to the patients. These will be administered a combination of transcutaneous electrical nerve stimulation, ultrasound, a hot pack, and stabilization training 3 times a week for 4 weeks by the physical therapist.

Reedco's posture score will be used in posture evaluation. The score is a standard tool and it is administered by visual inspection of 10 postural traits viewed laterally (sagittal view including neck, upper back, trunk, abdomen, and lower back) or from behind (coronal view including head, shoulders, spine, hips, and ankles). The scores are marked as follows: a value of 0 equals poor posture or severe deviation, a value of 5 equals fair posture or minimal to moderate deviation, and a value of 10 equals good posture or normal alignment. The maximum score of 100 indicates good posture and a score of 59% or less is recorded as postural dysfunction.

Cervical ROM will be evaluated using a goniometer while the patient sitting on the chair with both feet on the ground. In the evaluation, after the goniometer is brought to the neutral position, the patient is asked to perform the desired movement with the head: flexion, extension, right and left lateral flexion, right and left rotation. A degree will be recorded for each neck motion and be used in the average analysis

Neck Disability Index will be used to evaluate daily activities and ability. The form contains of 10 questions related to pain intensity, lifting, concentration, reading, headache, self-management, driving, working, sleeping, and daily activities. The score of each question is 0-5 according to the options and the total score is recorded by adding the scores of all answers. The lower the total score of the test, the less the effect of pain on performance in daily activities. The higher the score, the greater the performance of daily activities is affected.
