TMJ and Myofascial Pain Syndrome Animation
The temporomandibular joint â€“ the TMJ isthe 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. Temporomandibulardisorders, or TMD, refer to a group of conditions characterized by pain in the jaw area andlimited movement of the mandible. TMD may be caused by problems in the joint itselfor in the muscles surrounding the joint. Problems in the joint include: arthritis, inflammationand internal derangements. When the problem is in the muscles, the condition is calledmyofascial pain syndrome. Myofascial pain syndrome is very common andcan occur in patients with a normal temporomandibular
joint. The syndrome is characterized by presenceof hyperirritable spots located in skeletal muscles called trigger points. A trigger pointcan be felt as a nodule of muscle with harder than normal consistency. Palpation of triggerpoints 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 unconsciouslyduring sleep. The medical term for this condition is â€œnocturnal bruxismâ€�. A trigger pointis composed of many contraction knots where individual muscle fibers contract and cannotrelax. 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 patternsare therefore consistent and are well documented for various muscles.Trigger points in the masseter refer pain to the cheeks, lower jaw, upper and lowermolar teeth, eyebrow, inside the ear and around the TMJ area. Trigger points in the temporalisare also associated with headache and toothache from upper teeth. The main culprits of myofascialpain in the TMJ area are the pterygoid muscles. Trigger points in medial pterygoid refer painto the TMJ region in front of the ear, inside
the mouth and upper outside of the neck. Theymay also manifest as sore throat and difficulty swallowing. Pain from lateral pterygoid triggerpoints 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. Treatmentoptions 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 asneedling and â€œspray and stretchâ€�.
Wrist and Forearm Pain with Curls AX JEFF
'HI, Jeff. This is Sorro from India, and my'AX Jeff' question is, Whenever I am doing my bicep curls, I get a very sharp and a naggingpain in this portion of my wrist. And it only happens during the exercise whichinvolves the Barbell Curl. The outer part aches a lot and I'm not able to twist it inthis direction. This is fine. This movement and this movement is, I'm havinga problem with that. So, thank you.' Thanks, my man, for the question. It's actuallya very good question because this is a common problem that guys will have when they're doingthe Curl especially with the barbell. And a lot of it is anatomical, and a lot ofit also has to do with how we're performing
the Barbell Curl. So, I'll tell you why it's actually, you'regetting that pain in that spot right on the inside part of the wrist maybe even radiatingdown into the forearm. And more importantly what you can do so youcan start doing Curls again and not have to suffer that pain. If you look at the anatomical part of this,right. We have two bones that make up our forearm. We have the radius here, and thenwe have the ulna on the other side. So, the radius anatomically, is longer thanthe ulna. So, you can see, right as I put
my fingers on the corners of those two bones,you can do this yourself, just hook right on the end of your wrist. You'll see that my middle finger here is ontop of the radius that's longer and further down than the edge and end of my ulna whichis right here, ok. What happens is, our body wants to equalizethat difference so there's a little bit of a cartilaginous disk that sits right in betweenthe end of the ulna and then into the carpal bones. So, we close that gap down of the length differencebetween the two sides. Keep that in mind because
now when we go grab a barbell, and we go try to do our Barbell Curls whathappens is, as you try to curl a barbell, think about what you might do. You might try to start lifting by gettingmore of your body english into the move to help you to lift that heavier weight. Well, what happens is, your elbows almostcome underneath a little bit because what you're trying to do is actually get a littlebit of help from your pecs as you squeeze them together.
You're almost doing a little bit of a crossoverunderneath and lifting that way. So, as you do that, you're getting your shoulders involvedtoo. As you do that, your wrists are actually feelingthis type of torque and force even though they're restricted by the straightness ofthe bar. But, as you do this, and you're pushing allthat weight down, you're also getting that supination here at the wrist. Well, take this,turn your wrist upside down, k, like this. Bend it back and pull down. And even guysthat don't have pain in the wrist are going to find that the inside portion of the wrist,right in that area where that disk is,
you feel some pain because you're basicallycompressing that and causing a pretty uncomfortable sensation. You do that over and over and over again,you could actually wear down and cause damage to that cartilage disk that's in between yourulna and your carpal bones. So, again, as you curl up and you're tryingto, you're getting that supination and downward force, and that causes that pinch. So, thetwo things you can do to fix it, number 1 are, lift a little bit lighter weightbecause if you're not having to do this and you can keep it nice and strict,
