Randomized Controlled Trial Clinical Trial
False-positive rates of cervical zygapophysial joint blocks.
To determine the false-positive rate of anesthetic blocks of the medial branches of the cervical dorsal rami in the diagnosis of cervical zygapophysial joint pain. ⋯ Uncontrolled diagnostic blocks are compromised by a significant false-positive rate that seriously detracts from the specificity of the test.

The purpose of the present study was to examine factors that influence individual differences in treatment response after multidisciplinary pain management. ⋯ Changes in coping strategies and negative thinking may be important mechanisms related to improvement, or lack of improvement, in a range of outcome measures. Patients from families who are controlling and disorganized, and patients high on negative thinking at pretreatment may represent high-risk groups in need of further individually tailored interventions.

To develop a methodology for translating the McGill Pain Questionnaire (MPQ) into a Danish version, and to make comparisons to studies of patients speaking other languages. ⋯ The present methodology of translating the McGill Pain Questionnaire permits comparison of studies from English-speaking and non-English-speaking populations, thus facilitating international research exchange.

The study investigates the physiological responses of preterm infants to procedures that are routinely performed in intensive care nurseries. Changes in heart rate, respiration rate, and oxygen saturation were examined as indicators of the level of discomfort experienced by the infant during the procedures. ⋯ The outcome measures appear to be reliable indices of preterm infant responses to painful stimulation.
