This is a "proof of concept study" to test the hypothesis that pulsed radiofrequency, PRF, produces cell stress at the primary afferent level without signs of overt thermal damage. We assumed that cell stress would result in impairment of normal function, and used the expression of activating transcription factor 3, ATF3, as an indicator of cellular "stress". ⋯ PRF has a biological effect, unlikely to be related to overt thermal damage. It appears to be selective in that it targets the group of neurons whose axons are the small diameter C and Adelta nociceptive fibres.

(a) To investigate how widespread is the use of long term treatment without improvement amongst clinicians treating individuals with low back pain. (b) To study the beliefs behind the reasons why chiropractors, osteopaths and physiotherapists continue to treat people whose low back pain appears not to be improving. ⋯ Long-term treatment of patients with low back pain without objective signs of improvement is an established practice in a minority of clinicians studied. This approach contrasts with clinical guidelines that encourage self-management, reassurance, re-activation, and involvement of multidisciplinary teams for patients who do not recover. Some of the rationale provided makes a strong case for ongoing contact. However, the practice is also maintained through poor communication with other professions and mistrust of the healthcare system.

It is widely accepted that chronic pain is best treated by a multidisciplinary team. Team approaches are best facilitated if all members understand their own and each others role. Roles and responsibilities have inherent values and beliefs which need to be understood if the team is going to function optimally. Little is known about the attitudes and beliefs of the pain team or the individual professionals within it. All members of the pain team therefore need to critically examine the values and beliefs they bring to these teams. The aim of this study was to start this process for nurses. This was done uniquely by: finding out what components of pain management nurses endorse as important; investigating their beliefs about pain management; and exploring whether nurses' beliefs differ in relation to other service providers. ⋯ The findings of this study are congruent with emerging literature highlighting the complexity of health care. The high endorsement patterns seen in this study could be taken as support that nurses are, either tacitly or overtly, aware of this need to approach pain management in an open-minded and flexible manner.

We have compiled a comprehensive QST protocol as part of the German Research Network on Neuropathic Pain (DFNS) using well established tests for nearly all aspects of somatosensation. This protocol encompasses thermal as well as mechanical testing procedures. Our rationale was to test for patterns of sensory loss (small and large nerve fiber functions) or gain (hyperalgesia, allodynia, hyperpathia), and to assess both cutaneous and deep pain sensitivity. ⋯ There was no significant right-to-left difference for any of the QST parameters; left-to-right correlation coefficients ranged between 0.78 and 0.97, thus explaining between 61% and 94% of the variance. This study has shown that a complete somatosensory profile of one affected area and one unaffected control area, which will be necessary to characterize patients with a variety of diseases, can be obtained within 1 h. Case examples of selected patients illustrate the value of z-transformed QST data for an easy survey of individual symptom profiles.

Recent efforts to operationalize persons' readiness to adopt a self-management approach to chronic pain have met with promising, but somewhat limited, results. The current study describes the development and psychometric evaluation of a German version of Pain Stages of Change Questionnaire (PSOCQ). A new item pool was developed to attempt to improve in particular the discriminant validity of the scales and in order to obtain a shortened measure. ⋯ Both the concurrent and divergent validity indices and the relationships between scale scores and pain related variables proved to be consistent with the transtheoretical model. Confirmatory factor analysis using LISREL performed on the second half of the sample supported the goodness-of-fit of the structure model. Implications of these findings for future research exploring the relevance of the pain stages of change model are discussed.
