For a normative study of chronic low back pain (CLBP), 702 consecutive admissions to a large multidisciplinary CLBP treatment program were assessed at admission, discharge, and 1-month follow-up, using a variety of psychological and functional performance instruments. Both univariate and multivariate approaches to appraising success are evaluated. ⋯ Composite indices of improvement demonstrated favorable outcomes for no less than four in every ten, and as high as nine in every ten participants. Because of the large sample size, relationships both within and across measurement domains can be assessed statistically: the separate sets of outcome measures, with the exception of psychological profiles, are generally independent of each other.

[Percutaneous lumbar facet denervation. Indications and significance in chronic backache].
The lumber facet joints have been established as a source of low back pain which may radiate to the leg. Because there are no reliable clinical signs which confirm the diagnosis injections of an anaesthetic agent into the joints are necessary. Therapeutically a percutaneous radiofrequency destruction of the medial branches of lumbar dorsal rami may relieve such pain. Success rate, however, is depending on a careful selection of patients.

The Minnesota Multiphasic Personality Inventory (MMPI) profiles of 205 male and 157 female patients with acute and chronic low back pain (LBP) were studied for replicable homogeneous subgroups using three cluster-analysis procedures. Two normal and three clinically elevated profile subgroups were identified. The two normal subgroups were characterized by relatively normal musculoskeletal condition and were least disabled, but they differed somewhat from each other in duration of pain, presence of physical abnormalities, and daily functioning. ⋯ The fifth and most pathologic profile subgroup surprisingly consisted largely of acute-pain patients whose musculoskeletal condition and daily functioning were similar to those of the normal subgroups. Patients in the three abnormal MMPI subgroups were exposed to more LBP physical-risk factors in the workplace. Implications for psychological treatment with these different profile types are discussed.
