Chronic low back pain (CLBP) with functional disability is a frequent and costly medical issue.1,2 Although LBP–related disability often impinges on physical, mental, and social well-being, the long-standing nature of the complaint is incompletely understood. However, numerous studies have elaborated on the issue and tried to link different types of factors to prolonged LBP. Sociodemographical factors (e.g., age, sex, work status, and smoking), behavioral factors (e.g., body mass index [BMI]), and illness-related factors (e.g., pain and mental distress) are suggested to influence disability. Others suggest that objective spinal pathologies (e.g., Modic changes [MCs] or annular tears) are prognostic or even causative factors of LBP
