Differences in pain function and coping in Multidimensional Pain Inventory subgroups of chronic back pain: a one-group pretest-posttest study

摘要

BackgroundPatients with non-specific back pain are not a homogeneous group but heterogeneous with regard to their bio-psycho-social impairments. This study examined a sample of 173 highly disabled patients with chronic back pain to find out how the three subgroups based on the Multidimensional Pain Inventory (MPI) differed in their response to an inpatient pain management program.
