Objectives. The objective was to investigate whether a treatment with a needle stimulation pad (NSP) changes perceived pain and/or sensory thresholds in patients with chronic neck (NP) and lower back pain (BP). Methods. 40 patients with chronic NP and 42 patients with chronic BP were equally randomized to either treatment or waiting list control group. The treatment group self-administered a NS...

ABSTRACT BACKGROUND AND OBJECTIVES: It is possible that patients submitted to lumbar spine surgery present chronic pain and need a multidimensional assessment of postoperative due the variables influence pain. The objective this study was evaluate correlation between uni scales for assessment. METHODS: Longitudinal observational carried out in inpatient units an orthopedic reference hospital Sa...

Attitudes to pain medication are important aspects of adjustment to chronic pain. They are measured by the 47-item Pain Medication Attitudes Questionnaire (PMAQ). To measure those attitudes more quickly and easily, we developed and evaluated a 14-item PMAQ using data from 3 separate surveys of people with pain in the general population. In survey 1, participants (n = 295) completed the 47-item ...

A green-lipped mussel (GLM) preparation was evaluated in a randomized, double-controlled and double-blinded clinical trial. It was hypothesized that the treatment effect would be less than that of the positive control (carprofen) but more than that of the negative control (placebo). Forty-five dogs with chronic pain and a radiographic diagnosis of osteoarthritis that were randomly allocated int...

introduction: in order to study the alterations of beta 1 and 2 integrins mrna level in rat lumbar spinal cord following the induction of chronic pain and its effect on the development of tolerance to morphine analgesia, we examined the level of expression of these genes in the presence of chronic pain, which is an inhibitor of morphine tolerance. we used induction of chronic pain alone and in ...

In this article we consider a new derivation mode for generalized communicating P systems (GCPS) corresponding to the functioning of population protocols (PP) and based on the sequential derivation mode and a fairness condition. We show that PP can be seen as a particular variant of GCPS. We also consider a particular stochastic evolution satisfying the fairness condition and obtain that it cor...

The orthorectification accuracies of Bilsat Multispectral (XS) imagery using a rigorous and eight simple geometric models are presented. Majority of the selected test area was covered by the existing large scale digital orthophotos, which were used as the source to collect Ground Control Points (GCPs). For the orthorectification process, a DEM generated from stereo ASTER images was used. The de...

To generate an accurate digital elevation model (DEM), Interferometric Synthetic Aperture Radar (InSAR) requires precise orbit data and baseline information, which are not always available. An alternative approach is to apply quality ground control points (GCPs) into the InSAR processing. However, locating high quality GCPs can also be difficult task, due to the low spatial resolution and radio...
