Chronic Neck Pain: Mobility, Sleep, Function

The goal of this observational study is to compare pain, cervical mobility, sleep quality, and functional status between individuals with chronic neck pain (CNP) and healthy individuals. The study focuses on understanding the complex relationships between these factors in individuals with CNP, with the aim of providing insights that could contribute to more effective rehabilitation strategies. The main questions it aims to answer are: * How pain, cervical mobility, sleep quality, and functional status differs between individuals with and without chronic neck pain? * What is the relationship between functional status and cervical mobility and sleep quality in individuals with chronic neck pain?
