Myofascial pain syndrome and trigger points. Reasons

Trigger points are caused by muscle injury. Muscles can be injured suddenly in accidents, or damage can occur slowly, due to repeated movements or poor posture. A muscle is composed of tiny fibers, which contract and relax in response to messages from the brain.

When muscle fibers become injured or over stimulated, they cannot relax and form contraction knots. A trigger point consists of many contraction knots, where individual muscle fibers contract and cannot relax. Fibers, extending from the trigger point to the muscle attachments shorten, and form a tight band.

The persistent contraction of muscle fibers compresses blood vessels and decreases their blood supply, leading to oxygen starvation and the accumulation of waste products. This irritates nerves and causes pain. Activated pain receptors generate specific referred pain patterns, depending on nerve passage and muscle anatomy.

Finally....a simple video, that explains a lot! Thank you so

[Eva-ruen]

Wow that trigger point is exactly where my pain is!! After all these years, I believe I will finally be pain free, thank you!!

Dry needling is an effective, non-pharmacological treatment of MTrPs which has approached acceptance as the “standard of practice” for deactivating active MTrPs. It may be performed using either a superficial or deep dry needling technique. Elicitation of one or more local twitch responses (LTRs) is a goal of dry needling and often benefits those with pain secondary to MTrPs. Though the mechanism of an LTR is unknown, studies suggest a biochemical component. Five minutes after the induction of a single LTR, our group found a dramatic change in the biochemical milieu of the upper trapezius muscle. Within minutes of the LTR, the initially elevated levels of SP and CGRP within the active MTrP drastically decreased to levels approaching that of normal uninvolved muscle tissue. The reduction of these
biochemicals in the local muscle area may be due to a small, localized increase in blood flow and/or nociceptor and mechanistic changes associated with an augmented inflammatory
response[17, 18]. Though not designed as a treatment intervention, the results of these studies are provocative in that the substances analyzed are known to be associated with sensitization, persistent pain, and spinal facilitation. In an animal model, it appears that dry needling may, in fact, activate the descending inhibitory pain system and cause local deactivation of the MTrP[35].

Dry needling — peripheral and central considerations
Jan dommerholt

"Dry needling is a common treatment technique in orthopedic manual physical therapy. Although various dry needling approaches exist, the more common and best supported approach targets MYOFASCIAL TRIGGER POINTS.

From a pain science perspective, trigger points are constant sources of peripheral nociceptive input leading to peripheral and central sensitization."

Thank you for this explanation. It describes perfectly what I've been suffering with for a extremely long time

[gadineshkumar]

After a year long treatment, I have finally met a physiotherapist who understood that I had a myofascial muscle knot on my back and helped me relieve it. This video explains it beautifully. Thank you.

[williamwomack]

Graphics are amazing!!! Computer voice...not so much... couldn’t someone just talk? Great simple video.

[DumSpiroSpero]

This was by far the best visual for my issues with this.

[patriciaoreilly]

Interesting. I had it on my left side shoulder blade for two weeks very uncomfortable. I am more careful of Posture but the main thing I did was exercise my shoulders - arms with stretch many times a day. Pain has gone 3 days now & hopefully will never return. Slouching over Christmas Period add a little tension that's how I felt so bad 👎 Exercise & Positive Mind . Hope anyone suffering from this gets well soon its a horrible pain on the plus side I know do more daily arm stretching.

[ahmed_boukerma]

What is the solution? How do I untie this muscle knot?

[nawtmyrealnamelol]

Exact spot I have pain. The problem with self-massaging that spot is it tightens your muscles on the other shoulder, so you have to just go back and forth

[brendaechols]

Exactly the spot. Even medication hasn't released the muscle tension.

[youngblood]

I went to the doctors they couldn't help you tube what i was feeling an wow now i know what it is .i love YouTube

[vr]

This video came to me. One thing that was not noted. Trigger point of this nature can also be referred pain coming from the cervical region. To many subjected opinions.

[IamtheShiatsulady]

They were acupuncture points! Si12 ans Gb21.

[lovmuzik]

It could the way you sleep too.that was my issue

[prabhkaransingh]

I am suffering from this from a very long time.... Plz tell me how to treat it Please

[jordazmo]

Great... So how do i make it not happen?

[brodhax]

If you poke it but it does NOT causes pain somewhere else, is it a trigger?

I have tender spots but they dont cause pain in other places. So im so confused

[salilmahadik]

Good video with explanation. Can Epsom salt spray on the affected part help ? Thanks

[davidemazzotti]

Trigger point are NOT caused by injuries... not a nice start for a video that, otherwise, is quite accurate.
