TMJ and Myofascial Pain Syndrome Animation
The temporomandibular joint â€“ the TMJ is the joint between the lower jawbone the mandible and the temporal bone of the skull. The TMJ is responsible for jaw movement and enables chewing, talking and yawning. Temporomandibular disorders, or TMD, refer to a group of conditions characterized by pain in the jaw area and limited movement of the mandible. TMD may be caused by problems in the joint itself or in the muscles surrounding the joint. Problems in the joint include: arthritis, inflammation and internal derangements. When the problem is in the muscles, the condition is called myofascial pain syndrome. Myofascial pain syndrome is very common and can occur in patients with a normal temporomandibular.
Joint. The syndrome is characterized by presence of hyperirritable spots located in skeletal muscles called trigger points. A trigger point can be felt as a nodule of muscle with harder than normal consistency. Palpation of trigger points may elicit pain in a different location. This is called referred pain. Trigger points are developed as a result of muscle overuse. Commonly, the muscles of chewing, or mastication, are overworked when patients excessively clench or grind their teeth unconsciously during sleep. The medical term for this condition is â€œnocturnal bruxismâ€�. A trigger point is composed of many contraction knots where individual muscle fibers contract and cannot relax. The sustained contraction of muscle.
Sarcomeres compresses local blood supply, resulting in energy shortage of the area. This metabolic crisis activates pain receptors, generating a regional pain pattern that follows a specific nerve passage. The pain patterns are therefore consistent and are well documented for various muscles. Trigger points in the masseter refer pain to the cheeks, lower jaw, upper and lower molar teeth, eyebrow, inside the ear and around the TMJ area. Trigger points in the temporalis are also associated with headache and toothache from upper teeth. The main culprits of myofascial pain in the TMJ area are the pterygoid muscles. Trigger points in medial pterygoid refer pain to the TMJ region in front of the ear, inside.
The mouth and upper outside of the neck. They may also manifest as sore throat and difficulty swallowing. Pain from lateral pterygoid trigger points can be felt in front of the ear and on the upper jaw. Treatments aim to address bruxism, to relieve muscle spasm and release trigger points. Treatment options include: Therapies: stress management, behavior therapy, biofeedback to encourage relaxation. Dental night guards: Splints and mouth guards to protect the teeth from damage. Medication: pain relievers, muscle relaxants, botox injections. Trigger points release techniques such as needling and â€œspray and stretchâ€�.
Massage Tutorial Myofascial release for TMJjaw pain
I’m Ian Harvey, massage therapist. Today we’re going to talk about jaw pain, TMJ dysfunction, all this stuff that can go on with the clicking and discomfort. This is actually very common problem. If you ask any of your clients that have neck or headache or shoulder pain, quot;hey, do you also have jaw pain?quot; a lot more than you think are going to say, quot;oh yeah, I do have that.quot; We’re going to start with an anatomy review, we’ll talk about this very complex joint right here, and all the muscles that surround it. Then we’ll get a client on the table and I’ll show you some easy myofascial techniques.
That are very effective at reducing this pain and the dysfunction, without a lot of digging or discomfort. If you’d like to skip ahead to any section, please click on the timecodes down in the description. So, first of all, what is this temporomandibular joint, this TMJ? Well, let’s start by talking about the mandible. The mandible is your jaw right here, and it goes up in this broad flat surface of bone called the ramus, and the ramus has tw upward projections. The more anterior projection slides under this zygomatic arch here, this cheekbone, so it goes up under here and it makes contact with the temporalis muscle. We’ll talk.
About that more in a second. You can feel this projection if you open your jaw wide, which I don’t recommend if you’ve got jaw dysfunction yourself. There it is. And that’s called the coronoid process. Posterior to that we’ve got another projection upward of the ramus, this is called the condyle of the mandible, and this is the one that makes contact with the temporal bone forming that temporomandibular joint. Now this is both a hinging and gliding joint, it’s a very mobile joint, and that’s one reason why it can get into trouble. And, one reason why it’s so.
Mobile is because it’s got an articular disc in here. It’s this little disc of fibrocartilage that’s embedded within the joint space, and it allows this joint to do all sorts of fun tricks, like protrusion and sliding from side to side. And this disc actually interfaces with of your muscles of mastication, the lateral pterygoid muscle, and it can get pulled out of place, just during normal movements of mastication (otherwise known as chewing), or while you are unconsciously clenching your teeth or grinding your teeth, known as bruxism. Now, our mission isn’t to fix this disc, it.
Isn’t to shove this disc back where it belongs. It’s to reduce this high tension situation that’s happening across this joint. And by doing that, that disc will start resuming its normal function. I find that getting this high tension situation to calm down will do the work for us. There’s nothing specific that we need to do to change this joint. The two main muscles that we’re going to be worrying about today are the masseter, the masseter is actually a twoheaded muscle, we’re not going to worry about the individual heads. It originates from this zygomatic arch, and it goes down onto the entire ramus, and down to the angle.
Of the mandible. So it’s a very broad insertion. And it’s a very interesting and convoluted muscle. If you feel lumps and bumps and taut bands across here, don’t assume that you found a trigger point, this is just a very lumpy bumpy muscle. And we’ve also got the temporalis muscle. The temporals has a very broad origin up here on the lateral skull, it covers the temporal bone, and it’s in this temporal fossa. And the big broad fan of this muscle, it narrows narrows narrows down into a tendon that passes under that zygomatic arch and makes contact with that coronoid process. We’ve also got pterygoid muscles which are.
Less accessible, and that we’re going to be worrying about a little bit less today. Some of them are most easily accessed intraorally, so we would have to glove up and go into the oral cavity, and I don’t tend to do those, I find that I can get a lot done just working externally, and by working with all of this fascia that all these muscles are embedded in, we can get everything to calm down, without having to focus too much on any one individual muscle. By the way, in a past.
