Conclusions and Relevance Cannabinoid drugs may prevent the onset of pain by producing small increases in pain thresholds but may not reduce the intensity of experimental pain already being experienced ; instead , cannabinoids may make experimental pain feel less unpleasant and more tolerable , suggesting an influence on affective processes .
Cannabis-induced improvements in pain-related negative affect may underlie the widely held belief that cannabis relieves pain
Importance Cannabinoid drugs are widely used as analgesics , but experimental pain studies have produced mixed findings .
The analgesic properties of cannabinoids remain unclear .
Objective To conduct a systematic review and meta- analysis of the association between cannabinoid drug administration and experimental pain outcomes in studies of healthy adults .
PEDro. A database of randomized trials and systematic reviews in physiotherapy.
This paper describes PEDro , the Physiotherapy Evidence Data base . PEDro is a web-based data base of r and omized controlled trials and systematic review s in physiotherapy . It can be accessed free of charge at http://ptwww.cchs.usyd.edu.au/pedro . The data base contains bibliographic details and abstract s of most English- language r and omized trials and systematic review s in physiotherapy , and of many trials and review s in other language s. Trials on the data base are rated on the basis of their method ological quality so that users of the data base can quickly identify trials of high quality . Trials and systematic review s are extensively indexed to facilitate search ing . PEDro provides an important information re source to support evidence -based clinical practice
