Chronic neck pain is one of the musculoskeletal pain problems that can cause chronic disability. It is emphasised that individuals with chronic neck pain have difficulty during different activities in their daily lives, and that this problem is a very common health problem that can lead to disability. In the case of chronic neck pain, changes in the pain threshold cause central sensitisation and individuals become more sensitive to pain stimuli. This situation can affect the processing of proprioceptive information and lead to deterioration in proprioceptive perception. This situation leads to perceptual problems in body and neck awareness. Therefore, examining the relationship between the relevant parameters is important in the rehabilitation process. In this context, the aim of the study is to examine the relationship between body awareness and pain, central sensitisation, disability and proprioception in patients with chronic non-specific neck pain.
