The "centralization phenomenon" (CP) is the progressive retreat of referred pain towards the spinal midline in response to repeated movement testing (a McKenzie evaluation). A previous study suggested that it may have utility in the clinical diagnosis of discogenic pain and may assist patient selection for discography and specific treatments for disc pain. ⋯ Centralization is highly specific to positive discography but specificity is reduced in the presence of severe disability or psychosocial distress.

To identify and compare low back pain functional assessment tools and to determine their characteristics and the selection criteria for their use. ⋯ A "gold standard" to evaluate disability in low back pain does not exist, but only 4 tools (the Dallas Pain Questionnaire, Roland Disability Questionnaire, Quebec Back Pain Disability Scale and Oswestry Low Back Pain Disability Questionnaire) demonstrated strong qualities (content and construct validity, feasibility, linguistic adaptation and international use).

Comparative Study
Are the changes in postural control associated with low back pain caused by pain interference?
Voluntary limb movements are associated with involuntary and automatic postural adjustments of the trunk muscles. These postural adjustments occur prior to movement and prevent unwanted perturbation of the trunk. In low back pain, postural adjustments of the trunk muscles are altered such that the deep trunk muscles are consistently delayed and the superficial trunk muscles are sometimes augmented. This alteration of postural adjustments may reflect disruption of normal postural control imparted by reduced central nervous system resources available during pain, so-called "pain interference," or reflect adoption of an alternate postural adjustment strategy. ⋯ The results suggest that altered postural adjustments of the trunk muscles during pain are not caused by pain interference but are likely to reflect development and adoption of an alternate postural adjustment strategy, which may serve to limit the amplitude and velocity of trunk excursion caused by arm movement.

Translation and validation of the danish version of the Bournemouth questionnaire.
Translation, cultural adaptation, and validation of the Danish version of the Bournemouth Questionnaire (BQ). ⋯ The BQ was successfully translated and culturally adapted into Danish. The BQ was successfully tested for validity, consistency, and responsiveness against the Danish version of the SF-36 and RMDQ.

[Knowledge, practice and attitudes to back pain among doctors, physiotherapists and chiropractors].
In Norway, only doctors, physiotherapists and chiropractors are authorised to examine and treat patients suffering from low back pain. This study compares knowledge, attitudes and practice among these professional groups. ⋯ The chiropractors had the largest number of back pain patients in their practice and expressed the highest degree of professional interest in the field. We found no essential differences regarding knowledge between the groups. 77 % of the physiotherapists would refer acute sciatica to a doctor, while only 24 % of the chiropractors would do so. 65 % of the doctors and 10 % of the chiropractors would refer a chronic low back pain patient for physical therapy. Doctors and physiotherapists have a longstanding tradition of mutual cooperation, while chiropractors only seldom seem to refer to other care providers. One in five doctors and chiropractors, and 13 % of the physiotherapists, refer an acute unspecific low back pain to plain X-ray, which is not in accordance with the guidelines. Very few health care providers regarded low back pain as disabling. There are also few professionals who believe it possible to find an exact cause for the back pain in the individual patient.
