Diagnostic utility of the McGill Pain Questionnaire and the Oswestry Disability Questionnaire for classification of low back pain syndromes.
Verbal pain description and assessment of functional limitations are key components in the clinical evaluation of patients with low back pain syndromes. Using the McGill Pain Questionnaire (MPQ) to quantify the pain experience and the Oswestry Disability Questionnaire (ODQ) to quantify functional disability, a study was undertaken to determine the efficiency with which the MPQ and ODQ were capable of enhancing the differential diagnosis of three broad categories of low back syndromes. Three discriminative models were employed. ⋯ The greatest utility of the discriminant models was found to be ruling out nonspecific low back pain and ruling in radiculopathy, with and without neurological deficits. Subjective pain and disability appear to have the potential for successfully differentiating broad categories of low back pain. Further studies need to be performed to assess the discriminant power of the MPQ and ODQ for specific diagnostic entities.

Although patients with chronic pain are often psychologically distressed, it has been difficult to determine whether this distress is an antecedent of chronic pain or whether it is caused by the experience of living with chronic pain. The aim of this investigation was to develop a method that would allow individuals who are at risk for the development of chronic pain to be studied before their pain has become chronic. Patients with acute herpes zoster were assessed with demographic, medical, pain, and psychosocial measures. ⋯ Patients who developed chronic herpes zoster pain, however, had significantly greater pain intensity, higher state and trait anxiety, greater depression, lower life satisfaction, and greater disease conviction at the initial assessment than patients who did not develop chronic pain. In discriminant analyses, disease conviction, pain intensity, and state anxiety each made a unique contribution to discriminating patients who did and who did not develop chronic pain. This study demonstrates the feasibility of investigating psychosocial antecedents of the development of chronic pain by prospectively examining the longitudinal course of herpes zoster.

The purpose of this study was to determine the factors that are associated with child, parent, and nurse ratings of acute pediatric pain and distress during venipuncture. The behavior of eighty-five pediatric cancer patients during venipuncture was recorded by trained raters, and their observations were compared with ratings of pain and distress obtained from parents, pediatric patients, and pediatric nurses. Regression analyses indicated that ratings made by the child, parent, and nurse reflect different perspectives. Nurses' ratings were based upon overt distress, parents' ratings reflected their subjective perception of the child's pain, and the child's self-report was associated with the child's chronologic age.

Pain perception threshold (PPT), maximal pain tolerance (MPT) and pain discrimination of CLBP patients and controls were tested. Pain perception threshold was significantly higher in the patient group for two different pain stimuli (electrical and pressure pain). ⋯ It is concluded that CLBP patients have a decreased sensitivity for experimental pain. Two theories which might explain this decreased sensitivity are discussed.

Using a new electronic algometer, the mean values and standard deviations of pressure pain threshold and the intrarater and interrater reliability were evaluated on 13 muscles of the human head and neck region. The subjects were 40 healthy individuals, 21 females and 19 males. ⋯ Statistically significant correlation coefficients were obtained from the values of intra-examiners and inter-examiners in all muscles except the medial pterygoid and middle sternocleidomastoid muscle in male subjects (p < 0.05). This study showed that the electronic algometer could be recommended for evaluation of the pressure pain threshold of human head and neck muscles in clinical and experimental studies.
