LIDOCAINE INJECTION VERSUS DRY NEEDLING TO MYOFASCIAL TRIGGER POINT: The Importance of the Local Twitch Response
  • C. Hong
  • Medicine
  • American journal of physical medicine…
  • 1 July 1994
TLDR
It is essential to elicit LTRs during injection to obtain an immediately desirable effect, and TrP injection with 0.5% lidocaine is recommended, because it reduces the intensity and duration of postinjection soreness compared with that produced by dry needling. Expand
Interrater reliability in myofascial trigger point examination
TLDR
An initial attempt to establish the interrater reliability of the trigger point examination that failed, and a second study by the same examiners that included a training period and that successfully established interRater reliability in the diagnosis of the MTrP are reported. Expand
Immediate effects of various physical therapeutic modalities on cervical myofascial pain and trigger-point sensitivity.
TLDR
Ischemic compression therapy provides alternative treatments using either low pressure and a long duration (90s) or high pressure (the average of pain threshold and pain tolerance) and short duration (30s) for immediate pain relief and MTrP sensitivity suppression. Expand
Pathophysiologic and electrophysiologic mechanisms of myofascial trigger points.

  • Medicine
  • Archives of physical medicine and rehabilitation
  • 1 July 1998
TLDR
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. Expand
The Myofascial Trigger Point Region: Correlation Between the Degree of Irritability and the Prevalence of Endplate Noise
TLDR
The irritability of an MTrp is highly correlated with the prevalence of EPN in the MTrP region of the upper trapezius muscle, and the assessment ofEPN prevalence in an MtrP region may be applied to evaluate the irritability. Expand
Pathophysiology of myofascial trigger point.
  • C. Hong
  • Medicine
  • Journal of the Formosan Medical Association…
  • 1 February 1996
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. Expand
Myofascial Trigger Points: Pathophysiology and Correlation with Acupuncture Points
TLDR
There are many similarities between MTrPs and acupuncture points including their location and distribution, pain and referred pain patterns, local twitch responses (de qi), and possible spinal cord mechanism. Expand
Endplate Potentials Are Common to Midfiber Myofacial Trigger Points
TLDR
Endplate noise was significantly more prevalent in myofascial trigger points than in sites that were outside of a trigger point but still within the endplate zone, and endplate noise seems to be characteristic of, but is not restricted to, the region of a myofAscial trigger point. Expand
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.

Difference in pain relief after trigger point injections in myofascial pain patients with and without fibromyalgia.
  • C. Hong, T. Hsueh
  • Medicine
  • Archives of physical medicine and rehabilitation
  • 1 November 1996
TLDR
Trigger point injection is a valuable procedure for pain relief for patients in both group and patients with FMS are likely to experience significant but delayed and attenuated pain relief following injection of their active TrPs compared to myofascial pain patients with similar TrPs but without FMS.
