ReviewPathophysiologic and electrophysiologic mechanisms of myofascial trigger points.
To review recent clinical and basic science studies on myofascial trigger points (MTrPs) to facilitate a better understanding of the mechanism of an MTrP. ⋯ The pathogenesis of an MTrP appears to be related to integrative mechanisms in the spinal cord in response to sensitized nerve fibers associated with abnormal endplates.

Venous hemodynamics of the lower extremities in response to electrical stimulation.
To evaluate the calf muscle pump function using an air plethysmograph (APG) applied to the lower leg of subjects during three different tiptoe exercises. ⋯ Periodic single ES-induced calf muscle contractions produced significant muscle pump function and could be used to improve venous blood flow and reduce stasis in the lower leg. Continuous ES-induced contractions, on the other hand, could improve lower leg peripheral perfusion while eliciting the physiologic venous muscle pump. Higher RV and RVF after 10 ES-induced contractions in this sample of healthy subjects with normal VFI may be caused by an increase in arterial blood perfusion after repeated ES-induced contractions.

To determine what percentage of patients have none of the five nonorganic behavioral processes known as Waddell signs, and the relational pattern between Waddell signs and somatic complaints, disturbed functional performance, negative treatment attitudes, physical pathology, depression, generalized anxiety, and MMPI-2 validity scales. ⋯ Taken together, multiple Waddell signs and some of their correlates present various factors that might interfere with optimal response to treatment.

Case ReportsFlashback and nightmares after surgery under neuraxial anesthesia: a report of two cases.
Recall, awareness, flashback, and nightmares are reported complications of general anesthesia, but flashback and nightmares after regional anesthesia have not been described. Two patients underwent vascular and orthopedic surgery under spinal and epidural anesthesia, respectively. ⋯ In both patients the anesthetic course was uneventful, but the recovery process was complicated by flashbacks and nightmares leading to depression, physical complaints, and lengthy convalescence. Flashback and nightmares after neuraxial anesthesia are unreported and, therefore, their incidence is unknown.

Randomized Controlled Trial Clinical TrialCombined exercise and motivation program: effect on the compliance and level of disability of patients with chronic low back pain: a randomized controlled trial.
To assess the effect of a combined exercise and motivation program on the compliance and level of disability of patients with chronic and recurrent low back pain. ⋯ The combined exercise and motivation program increased the rate of attendance at scheduled physical therapy sessions, ie, short-term compliance, and reduced disability and pain levels by the 12-month follow-up. However, there was no difference between the motivation and control groups with regard to long-term exercise compliance.
