Chronic non-specific low back pain is a common health problem that significantly affects the quality of life of individuals. Increased pain intensity leads to deficiencies in the body's sensory organization, resulting in decreased awareness. This can lead to dysfunction in body awareness, which is known as the ability of individuals to perceive the sensations and conditions of their bodies. Body awareness plays a critical role in pain management and mobility. Chronic pain causes constant stimulation in the nervous system, causing central sensitization, which is when the central nervous system becomes overly sensitive to pain signals. As a result, a decrease in the pain threshold, constant pain, and increased muscle tension occur. Increased pain intensity and decreased awareness can result in a decrease in the maintenance of optimal functions, affecting muscular endurance. Inadequate muscular endurance can increase low back pain and make it difficult for individuals to perform their daily activities. Therefore, this study aims to examine the relationship between body awareness, central sensitization, disability, and muscular endurance in patients with chronic non-specific low back pain.
