Randomized Controlled Trial Comparative StudyThe effect of total synovectomy in total knee arthroplasty: a prospective randomized controlled study.
The apparent synovial hypertrophy in some cases of noninflammatory knee osteoarthritis suggests that total synovectomy may provide beneficial inflammatory and pain relief after total knee arthroplasty. The aim of the study was to compare the effect of synovectomy on the postoperative pain, bleeding and functional outcome after surgical treatment of knee osteoarthritis. ⋯ Performing synovectomy in patients with primary knee osteoarthritis does not seem to have any clinical advantage besides it might increase blood loss and recurrent hemarthrosis postoperatively. Thus, during arthroplasty surgery, it should not be performed routinely.

Randomized Controlled Trial Comparative StudyEstimation of minimum clinically important difference for pain in fibromyalgia.
To estimate the minimum clinically important difference (MCID) for several pain measures obtained from the Brief Pain Inventory (BPI) for patients with fibromyalgia. ⋯ In these analyses, the MCIDs for several pain measures obtained from the BPI were similar (∼2 points) and corresponded to a 30-35% improvement from baseline to end point. These findings may be beneficial for use in designing clinical trials in which the BPI is used to evaluate improvements in pain severity.

Electromyographic assessment of dexamethasone in treatment of post-tonsillectomy pain: randomized, placebo-controlled trial.
Surface electromyographic (sEMG) study of post-tonsillectomy swallow-evoked muscular reactions was performed to assess analgesic properties of dexamethasone. ⋯ If dexamethasone is administered, the reduction of the postoperative pain could be secondary to the reduction of edema. The sEMG might be used for quantitative evaluation of analgesics via assessment of neuromuscular reactions to analgesia.

Reliability and validity of a visual analogue scale used by owners to measure chronic pain attributable to osteoarthritis in their dogs.
To assess validity and reliability for a visual analogue scale (VAS) used by owners to measure chronic pain in their osteoarthritic dogs. ⋯ Although valid and reliable, the pain VAS was a poor tool for untrained owners because of poor face validity (ie, owners could not recognize their dogs' behavior as signs of pain). Only after owners had seen pain diminish and then return (after starting and discontinuing NSAID use) did the VAS have face validity.

Reference values of mechanical and thermal pain tests in a pain-free population.
Quantitative sensory tests are widely used in human research to evaluate the effect of analgesics and explore altered pain mechanisms, such as central sensitization. In order to apply these tests in clinical practice, knowledge of reference values is essential. The aim of this study was to determine the reference values of pain thresholds for mechanical and thermal stimuli, as well as withdrawal time for the cold pressor test in 300 pain-free subjects. ⋯ In conclusion, normative values of parameters related to pressure, heat and cold pain stimuli were determined. Reference values have to be stratified by body region, gender and age. The determination of these reference values will now allow the clinical application of the tests for detecting abnormal pain reactions in individual patients.
