A group of patients with CLBP and WMP (CLBPWMP group, n97) was compared with a group of individuals who were pain-free and without a history of musculoskeletal problems (control group, n97) and with a group of patients with CLBP but without WMP (CLBP-only group, n52). The mean age of the participants was 42.9 years (SD8.74); 76% were women, and 24% were men.
