Virtual Reality Application for Assessing Neck Movement and Position Sense

The goal of this observational study is to examine whether a virtual reality application developed by our team can be used to evaluate cervical range of motion (ROM) and joint position sense (JPS) in individuals with chronic neck pain.

The main questions it aims to answer are:

* Does the virtual reality application provide reliable measurements of cervical ROM? * Does the application accurately assess cervical JPS when compared with a standard clinical tool (Cervical Range of Motion device, CROM)?

Researchers will compare results from the VR application with results from the CROM device to see if the two methods give similar outcomes.

Participants will:

* Complete a demographic and clinical evaluation. * Perform standardized neck movements (flexion, extension, left/right lateral flexion, left/right rotation). * Be assessed using both the CROM device and the VR application for ROM and JPS.
