Visual analogue scale will assess pain intensity.The visual analog scale (VAS) is a validated, subjective measure for acute and chronic pain. Scores are based on self-reported measures of symptoms that are recorded with a single handwritten mark placed at one point along the length of a 10-cm line that represents a continuum between the two ends of the scale- "no pain" on the left end (0 cm) of the scale and the "worst pain" on the right end of the scale (10 cm).

The measurements of the cervical range of motion, carried out with the CROM goniometer, The goniometer was placed on the subject's head and a magnetic collar was attached to their shoulders; it was always arranged in the same position with respect to the magnetic pole. During all the measurements, the subjects were seated, with their back straight, and looking ahead; their feet were supported on the floor. The subjects remained in the same sitting position from the moment the recording procedure was started.

The measurement was performed during "half a cycle" of the movement, i.e., from "the neutral" position to the final range of motion in a given plane.

Arabic neck disability index will be used to assess neck disability.The NDI has also been shown to be valid when comparing it to other pain and disability measures. Questions include activities of daily living, such as: personal care, lifting, reading, work, driving, sleeping, recreational activities, pain intensity, concentration and headache. Each question is measured on a scale from 0 (no disability) to 5, and an overall score out of 100 is calculated by adding each item score together and multiplying it by two. A higher NDI score means the greater a patient's perceived disability due to neck pain. The "minimally clinically important change" by patients has been found to be 5 or 10%
