Ultrasound therapy reduces persistent post-thoracotomy tactile allodynia and spinal substance P expression in rats.
Therapeutic ultrasound (TU) alleviates nerve injury-associated pain, while the molecular mechanisms are less clear. This is an investigator-initiated experimental study to evaluate the mechanisms and effects of ultrasound on prolonged post-thoracotomy pain in a rodent model. ⋯ The results of this study suggest an increase in mechanical withdrawal thresholds and subcutaneous temperature, as well as a downregulation of spinal substance P and IL-1β, in the group which received ultrasound treatment. The regulation of spinal substance P and IL-1β may mediate potential effects of this non-invasive treatment.

To linguistically and cross-culturally translate the Anterior Knee Pain Scale into French and to evaluate the reliability and validity of this translated version of the questionnaire. ⋯ A valid French version of the Anterior Knee Pain Scale is now available and can be used with confidence to better assess the disease burden associated with patellofemoral pain. It was successfully cross-culturally adapted into French. Implications for rehabilitation The results on psychometric properties of the French Anterior Knee Pain Scale are comparable with six validated versions obtained for the Finnish, the Turkish, the Chinese, the Dutch, the Thai and the Persian populations. The French translated version of the Anterior Knee Pain Scale is a reliable and valid instrument for assessing the functional limitations associated with patellofemoral pain. The test-retest reliability of the French Anterior Knee Pain Scale was excellent, the internal consistency was high and the construct validity was consistent. There were no floor/ceiling effects.

Randomized Controlled TrialImpact of patient choice for different postcesarean delivery analgesic protocols on opioid consumption: a randomized prospective clinical trial.
Choice of postcesarean delivery analgesic protocol may improve pain experience and reduce analgesic requirements. ⋯ Having a choice compared with no choice routine care did not reduce oxycodone requirements or pain scores. However, women have insight into their analgesic needs; women offered a choice and who chose the higher dose analgesic protocol required more oxycodone, and women who chose the lower dose protocol required less oxycodone. Despite providing additional analgesic (six times more intrathecal morphine plus gabapentin in high dose vs low dose protocols), we still did not equalize postcesarean oxycodone requirement differences between groups.

To determine the reliability and validity of self-reported questionnaires to measure pain and disability in adults with grades I-IV neck pain and its associated disorders (NAD). ⋯ The evidence supporting the validity and reliability of instruments used to measure pain and disability is preliminary. Further validity studies are needed to confirm the clinical utility of self-reported questionnaires to assess pain and disability in patients with NAD. These slides can be retrieved under Electronic Supplementary Material.

Normative data for common pain measures in chronic pain clinic populations: closing a gap for clinicians and researchers.
Normative data for chronic pain questionnaires are essential to the interpretation of aggregate scores on these questionnaires, for both clinical trials and clinical practice. In this study, we summarised data from 13,343 heterogeneous patients on several commonly used pain questionnaires that were routinely collected from 36 pain clinics in Australia and New Zealand as part of the electronic Persistent Pain Outcomes Collaboration (ePPOC) including the Brief Pain Inventory (BPI); the Depression Anxiety and Stress Scales (DASS); the Pain Self-Efficacy Questionnaire (PSEQ); and the Pain Catastrophizing Scale (PCS). The data are presented as summarised normative data, broken down by demographic (age, sex, work status, etc) and pain site/medical variables. ⋯ Scores tended to worsen with age until 31 to 50 years, after which they improved. Scores were worse for those who had a greater number of pain sites, were unemployed, were injury compensation cases, or whose triggering event was a motor vehicle accident or injury at work or home. These results and comparisons with data on the same measures from other countries, as well as their uses in both clinical practice and clinical trials, are discussed.
