In order to determine the relationship between trigger point sensitivity and the referred symptoms of myofascial pain, VAS ratings of referred pain intensity and pressure algometer measures of myofascial trigger point sensitivity were taken pre and post treatment of the muscle containing the trigger point with passive stretch. The results in 20 subjects,(More)
Memory for the intensity of past physical pain depends critically on the intensity of present pain. When their present pain intensity was high, patients with chronic headaches of myofascial origin rated their maximum, usual, and minimum levels of prior pain as being more severe than their hourly pain diaries indicated. When their present pain intensity was(More)
Three studies are presented demonstrating the reliability of the pressure algometer as an index of myofascial trigger point sensitivity. The first study showed high reliability between and within experimenters when measuring marked trigger point locations. In study 2, significant between experimenter reliability in locating and measuring the same unmarked(More)
Receptors believed responsible for the diuresis of negative pressure breathing have been located by observing the effect on urine flow of a stepwise engorgement of the intrathoracic vascular bed. Dis-tension of the pulmonary arterial tree (injection of plastic beads) and of the entire pulmonary circulation (snares on the pulmonary veins) were without(More)
BACKGROUND & AIMS Molecules that regulate T-cell adhesion to hepatic endothelium and thereby recirculation of T cells to the liver are poorly understood. Because the adhesion molecule vascular adhesion protein-1 (VAP-1), which mediates lymphocyte binding to lymph node endothelium, is expressed on hepatic endothelium, it could play a role in regulating(More)
Several studies have shown that surgical patients cannot consciously recall or recognize events to which they had been exposed during general anesthesia. Might evidence of memory for intraoperative events be revealed through the performance of a postoperative test that does not require remembering to be deliberate or intentional? Results of the present(More)
Three case presentations illustrate that the clinical signs and symptoms of occipital neuralgia may be produced by myofascial pain. Assessment of myofascial trigger points is needed before making a diagnosis of occipital neuralgia. Myofascial trigger points can be effectively treated with minimally invasive procedures, thereby avoiding irreversible surgical(More)
OBJECTIVE The present study sought to derive an algorithm using factor analysis and structural equation modeling (SEM) to describe headache and orofacial pain patients using measures of behavioral and psychological functioning. This investigation further examined whether the underlying factor structure differed in 3 presumed distinct diagnostic categories:(More)
The effects of transcutaneous electrical nerve stimulation (TENS) on myofascial pain and trigger point sensitivity were assessed. Four modes of TENS and a no-stimulation control were compared in a double-blind design. Stimulation, carried out for 10 min on 60 subjects (12/group), showed significant pain reductions with 100 Hz, 250 msec stimulation followed(More)
