A review is made of recent studies on myofascial trigger points (MTrP) and their mechanism is discussed. Clinical and basic science studies have shown that there are multiple MTrP loci in a MTrP region. A MTrP locus contains a sensory component (sensitive locus) and a motor component (active locus). A sensitive locus is a point from which tenderness or pain, referred pain, and local twitch response can be elicited by mechanical stimulation. Sensitive loci (probably sensitised nociceptors) are… 
Probable Mechanisms of Needling Therapies for Myofascial Pain Control
TLDR
Clinical and animal studies of remote AcP for MTrPs and the possible mechanisms of remote effectiveness are reviewed and discussed.
Needle Electromyographic Activity of Myofascial Trigger Points and Control Sites in Equine Cleido-Brachialis Muscle – An Observational Study
TLDR
Equine myofascial trigger points can be identified, and have similar objective signs and electrophysiological properties to those documented in human and rabbit skeletal muscle tissue.

PATHOGENESIS AND CHARACTERISTICS OF MYOFASCIAL LOW BACK PAIN
TLDR
It is important to determine and treat the underlying pathological lesions in order to avoid recurrence of myofascial LBP and to provide appropriate management based on the best knowledge.
Myofascial pain and dry needling for the trapezius muscle
TLDR
Trigger point dry needling is a good therapeutic option for addressing and managing my ofascial trigger points and myofascial pain in the trapezius muscle.

Acupuncture and Trigger Point Injections for Fibromyalgia: East-West Medicine Case Report.
TLDR
A case report is presented of a patient with fibromyalgia who was successfully treated with an integrative approach that combined acupuncture with trigger point injections that provides improved clinical outcomes.
Injection of Remote Myofascial Trigger Points for Pain Control: A Case Report
TLDR
After injection to the MTrPs in bilateral extensor carpi radialis longus, extensor indicis, and first dorsal interosseous muscles, the effectiveness of MTrP injection to bilateral upper trapezius muscles remarkably enhanced and this patient finally became almost pain free.
Dry Needling to a Key Myofascial Trigger Point May Reduce the Irritability of Satellite MTrPs
TLDR
Evidence is provided that dry needle–evoked inactivation of a primary (key) MTrP inhibits the activity in satellite MTrPs situated in its zone of pain referral, which supports the concept that activity in a primary MTrp leads to the development of activity in satellites MTrps and the suggested spinal cord mechanism responsible for this phenomenon.

Current Research on Myofascial Trigger Points–Pathophysiological Studies
TLDR
A clinical MTrP characteristically exhibits a sensory component [sensitive locus] and a motor component [active locus], which is the site from which spot tenderness, referred pain, and local twitch response [LTR] can be elicited by mechanical stimulation.

TLDR
The trigger point is a common pathogenic pathway of muscle pain from different causes and is usually activated by acute or chronic injury to a muscle, tendon, ligament, joint, disc or nerve.

This article presents a proposed technique of myofascial trigger point [TrP] injection modified from tha described by Drs.
Concomitant Sympathetically Mediated Pain and Myofascial Trigger Point Pain
TLDR
It is stressed that for the successful treatment of RSDS early diagnosis is essential and it is essential to search for myofascial trigger points and, when present, to deactivate these by means of acupuncture stimulation of A-δ nerve fibres present in the skin and subcutaneous tissues at the trigger point sites.

TLDR
Modulation of sensory inputs by use of many techniques may reduce pain more than by surgically interrupting the sensory input.
Distribution of Sensitive Loci Where Localized Twitch Response Can Be Elicited in Rat Skeletal Muscle
TLDR
It was found that, although some sensitive loci were distributed in the periphery, most of the sensitive loca were concentrated in the endplate zones, with statistical significance, which may further support the hypothesis that MTrPs are related to abnormal endplates.
Pressure Threshold for Referred Pain by Compression on the Trigger Point and Adjacent Areas
TLDR
It was found that the referred pain could be elicited with a higher incidence at site A than at site B, and the threshold of the pressure sufficient to induce local pain, referred pain and intolerable pain at site C.
