[39] [40] Concentrations of protons (H +), bradykinin, calcitonin gene-related peptide, substance P, tumor necrosis factor-β, interleukin 1-β, serotonin, and norepinephrine were found to be significantly higher in the active trigger point group than either of the other two groups (latent trigger points and no trigger points).

In common sense, refractory period is the characteristic recovery time, a period that is associated with the motion of the image point on the left branch of the isocline ˙ = [B: 1] (for more details, see also Reaction–diffusion and Parabolic partial differential equation).
Symptoms of a myofascial trigger point include: focal point tenderness, reproduction of pain upon trigger point palpation, hardening of the muscle upon trigger point palpation, pseudo-weakness of the involved muscle, referred pain, and limited range of motion following approximately 5 seconds of sustained trigger point pressure.

In neuroscience and neurology, a trigger zone is an area in the body, or of a cell, in which a specific type of stimulation triggers a specific type of response.. The term was first used in this context around 1914 by Hugh T. Patrick, who was writing about trigeminal neuralgia, a condition in which pain fibers in the trigeminal nerve become hypersensitive. [1]
For many years, it was believed that the axon hillock was the usual site of initiation of action potentials—the trigger zone. It is now thought that the earliest site of action potential initiation is at the axonal initial segment: just between the peak of the axon hillock and the initial (unmyelinated) segment of the axon.

No, cannot distinguish between active and latent states. The majority of healthy individuals will have latent HHV-6B. This test helps identify the type of HHV-6 but not its activity. Not specified in the original table. No Immunohistochemical Testing Yes, can detect virus replication through protein expression.
The course of the action potential can be divided into five parts: the rising phase, the peak phase, the falling phase, the undershoot phase, and the refractory period. During the rising phase the membrane potential depolarizes (becomes more positive). The point at which depolarization stops is called the peak phase. At this stage, the membrane ...
Dry needling for the treatment of myofascial (muscular) trigger points is based on theories similar, but not exclusive, to traditional acupuncture; both acupuncture and dry needling target the trigger points, which is a direct and palpable source of patient pain. [1]
