Each exercise session lasts 50 minutes, consisting of 10 minutes of warm-up, 30 minutes of stabilization exercises, and 10 minutes of cool-down. Stabilization exercises will be selected from an exercise pool according to the individual's needs, with progression ensured throughout the program. The exercises will be administered face-to-face twice a week for eight weeks, and participants will be provided with illustrated brochures and instructed to perform a one-hour home exercise program daily.

In this group, in addition to these exercises, connective tissue massage will be applied, starting from the basic regions and gradually incorporating other regions.

Also, the electrotherapy program consists of 20 minutes of infrared therapy, continuous ultrasound will be applied to the right and left sides for 7 minutes each at an intensity of 2 W/cm², and 20 minutes of conventional TENS will be administered to the painful area.

To assess disability in neck pain, only the Neck Disability Index (NDI), which evaluates current pain and disability, was used. The NDI consists of 10 items grouped into 6 subdomains. Each item is scored on a scale from 0 to 5, with higher scores indicating greater levels of disability.

To evaluate deep neck flexor muscle endurance, the Deep Cervical Flexor Test was used. This test assesses the maximal contraction capacity of the deep cervical flexor muscles. It is performed in the supine position, with the participant lifting the head approximately 2.5 cm off the surface while maintaining chin retraction. The examiner places a hand under the participant's occiput. The test is terminated when cervical flexion is lost or the participant's head touches the examiner's hand, and the duration is recorded in seconds.

Cervical range of motion was assessed using a universal goniometer. The participant was seated in an upright position, and measurements were taken for cervical flexion, extension, right and left rotation, and right and left lateral flexion. For flexion and extension, the acromion was accepted as the pivot point, with the stationary arm held parallel to the ground and the movable arm aligned with the ear line. For rotation, a straight rod was placed between the participant's teeth, the midline of the head was accepted as the pivot point, the stationary arm was kept parallel to the ground, and the movable arm was aligned with the rod. For lateral flexion, the spinous process of C7 was accepted as the pivot point, the stationary arm was positioned parallel to the ground, and the movable arm was aligned with the spinous processes of the cervical vertebrae. Care was taken to ensure that the head was not rotated during the measurements.

The World Health Organization Quality of Life Instrument, Short Form (WHOQOL-BREF) was used to assess the quality of life of the participants. The WHOQOL-BREF was developed by the World Health Organization and consists of six domains. Since each domain independently reflects the quality of life within its own scope, domain scores are calculated on a scale ranging from 4 to 20. Higher scores indicate better quality of life.
