Randomized Controlled Trial Comparative Study Clinical Trial
The placebo needle, is it a valid and convincing placebo for use in acupuncture trials? A randomised, single-blind, cross-over pilot trial.
The issue of what constitutes an effective and realistic acupuncture placebo control has been a continuing problem for acupuncture research. In order to provide an effective placebo, the control procedure must be convincing, visible and should mimic, in all respects, apart from a physiological effect, the real active treatment. The 'Streitberger' needle might fulfil these criteria and this paper reports on a validation study. ⋯ No major differences in outcome between real and placebo needling could be found. The fact that nearly 40% of subjects did not find that the two interventions were similar, however, raises some concerns with regard to the wholesale adoption of this instrument as a standard acupuncture placebo. Further work on inter-tester reliability and standardisation of technique is highly recommended before we can be confident about using this needle in further studies.

To compare patient, guardian and professional assessment of acute pain in children presenting to an Emergency Department, and to examine whether there was a correlation between the scores obtained using the Faces and linear scales for each group. ⋯ Professionals score pain lower than do children or guardians. Similar pain scores are obtained using both a Faces and a linear scale. This study offers no support for the introduction of a uniform pain assessment tool in a paediatric Emergency Department setting.

Comparative Study
A comparison of pain-assessment tools for use with elderly long-term-care residents.
The purpose of this study was to examine the psychometric properties (test-retest and interrater reliability, criterion concurrent validity) of 3 verbal pain-assessment tools (Faces Pain Scale, Numerical Rating Scale, Present Pain Intensity Scale) and a behavioural pain-assessment scale for use with an elderly population. The study used a repeated-measures design to examine the reliability and validity of the tools across 4 groups of participants with varying levels of cognitive impairment using a non-random stratified sample of 130 elderly long-term-care residents. The findings support the test-retest and interrater reliability of the behavioural pain-assessment tool across all levels of cognitive impairment, whereas the same measures of reliability for the verbal-report tools decreased with increasing cognitive impairment; however, the majority of elderly with mild to moderate cognitive impairment were able to complete at least 1 of these tools. The findings are discussed in relation to their clinical and research implications.
