background: the purpose of this research was to determine the relation between negative or positive qualitative troponin i test and the short term prognosis of patients presenting to emergency department with chest pain or angina equivalent symptoms. methods: we assessed the qualitative rapid troponin i in patients with chest pain or angina equivalent symptoms after at least 4 hours and then we...

purpose this preliminary study aimed to determine the intrarater reliability of the quantitative tests for the study of non-specific low back pain. methods test-retest reliability of the measurements of ratio data was determined by an intraclass correlation coefficient (icc), standard error of measurements (sems), coefficient of variation (cv), and one-way repeated measures anova using the valu...

Freedom from pain and physical distress is widely accepted as being a critical part of animal welfare. However, in order to minimize suffering by the animal we must first devise a scale with which to assess the degree of pain that it is feeling. There have been several important developments in animal research in the last twelve months pertaining to pain evaluation in animals. The aim of each o...

Pain drawings are often utilized in the documentation of pain conditions. The aim here was to investigate intra- and inter-rater reliability of area measurements performed on pain drawings consecutively, using the computer program Quantify One. Forty-eight patients with chronic nonmalignant pain had shaded in their experienced pain on the front and back views of a pain drawing. The templates we...

background several methods for assessment of severity of pain have been proposed but all of them are subjective. objectives this study evaluated the association concerning changes in electrical resistance (er) between two acupuncture points and severity of postoperative pain in order to define an objective measurement of pain. patients and methods in a cross-sectional study, 50 patients undergo...

BACKGROUND Opioid-induced hyperalgesia is a clinical syndrome whereby patients on long-term opioids become more sensitive to pain while taking opioids. Opioid-induced hyperalgesia is characterized by increased pain intensity over time, spreading of pain to other locations, and increased pain sensation to external stimuli. To characterize opioid-induced hyperalgesia, laboratory methods to measur...

Context Pain assessment, using an appropriate assessment tool, is a quality of marker1 2 and provides a method of evaluating the effectiveness of pain treatment. Best practice in the measurement of pain is patient self-report.3 Previous studies demonstrate that nurses do not routinely conduct pain assessment,4 pain tools are not used for assessment5 and that nurse and patient scores do not match.6

UNLABELLED Pain management outcomes assessment depends on valid measurement of pain. However, the validity of single-item scales, such as numeric or faces scales, with the assignment of ordinal numerical values to response scale categories, is questionable. The universal assumption that equal distances between response choices represent equal distances on the dimension being measured is essenti...
