This study seeks to address the identified research gap by objectively investigating the effect of Mulligan Cervical SNAGs on postural stability in individuals with chronic neck pain and mobility impairments. The findings aim to provide evidence-based insights into whether restoring joint mobility through this manual intervention can effectively enhance sensorimotor control and balance performance. The study aims to determine if adding SNAG to a conventional exercise program provides superior improvements in balance indices (OSI, APSI, MLSI), Pain, functional disability, Range of motion, Joint position sense, and kinesiophobia compared to exercise alone. The primary purpose of this study is to answer the following research questions:
* Does the application of cervical SNAGs lead to a significant improvement in the postural stability of patients with chronic neck pain with mobility deficits?
* Is there a correlation between the improvement in cervical range of motion (ROM) following SNAGs and the enhancement of postural control performance?
