Study: NCT06642233

Intervention type: DIAGNOSTIC_TEST
Intervention: The Neck Disability Index questionnaire
Description: The NDI evaluates the effect of neck pain on activities of daily living and social relationships. It consists of 10 items with 6 response options that are scored from 0 to 5 points each for a total possible score of 50. The classification of disability is based on the total score obtained, with higher number indicating greater disability.

Intervention type: DEVICE
Intervention: Body composition analysis using TANITA device
Description: TANITA device - body composition analyzer, the proportion of muscle mass and fat in the upper limbs~* Body height will be determined using a SECA 217 stadimeter.~* General and segmental body composition using the eight-electrode body composition analyzer by TANITA.

Intervention type: DIAGNOSTIC_TEST
Intervention: Cervical spine AROM (Active range of motion)
Description: Measurement of cervical spine AROM can be performed using the CROM system (Performance Attainment Associates, Roseville, MN, USA). Flexion, extension, side bending to the right and left, and rotation to the right and left of the cervical spine are examined.~The CROM measuring equipment consists of a helmet-shaped structure with the shape of glasses. These glasses adjust to the nasal septum thanks to the velcro on the back to fit them on the head. Three inclinometers for measuring on 3 cardinal planes were placed in the plastic construction.

Intervention type: DIAGNOSTIC_TEST
Intervention: Sagittal plane UCS AROM (Upper cervical spine active range of motion)
Description: Measurement of sagittal plane UCS AROM can be performed using the CROM system. Flexion and extension of the upper cervical spine are examined.

Intervention type: DIAGNOSTIC_TEST
Intervention: Flexion-Rotation Test
Description: The flexion-rotation test can be performed using the CROM system. Rotation of the upper cervical spine is tested while the cervical spine is flexed.

Intervention type: DIAGNOSTIC_TEST
Intervention: Sidebending-Rotation Test
Description: The sidebending-rotation test can be performed using the CROM system. Rotation of the upper cervical spine is tested while the cervical spine is in a lateral tilt.

Intervention type: DIAGNOSTIC_TEST
Intervention: Axial rotation test C0-C2
Description: The Axial rotation test C0-C2 can be performed using the CROM system. Rotation of the C0-C2 is examined.

Intervention type: DIAGNOSTIC_TEST
Intervention: Tilting test C0-C1 and C2-C3
Description: The Tilting test C0-C1 and C2-C3 can be performed using a goniometer. Lateral tilt of the C0-C1 and C2-C3 are examined.

Intervention type: DIAGNOSTIC_TEST
Intervention: Craniocervical flexion test
Description: The test measures the level of activation of the deep neck flexors using a pressure biofeedback device, an air-filled manual pressure cuff (Stabilizer TM, Chattanooga Group, INC., USA).

Intervention type: DIAGNOSTIC_TEST
Intervention: Craniovertebral angle
Description: The test measure the craniovertebral angle using a telephone placed on a tripod and a computer program. The CVA measurement is defined as the angle a horizontal line passing the neural spine of C7 in relation to the line connecting the tragus and the neural spine of C7.
