Hey everybody, it’s Jo. I got an emailfrom Barry and he was having some TMJ pain. TMJ stands for temporomandibular joint whichis your jaw joint right there. And I’m gonna show you today just some simple stretchesand strengthening exercises to get that TMJ feeling better. So we’re just gonna startoff, you want to start off gently with these exercises, you don’t want to push very hardbecause this joint is small and it can get irritated very quickly. The first one youwanna do is you’re gonna use the palm of your hand so you’re not pushing with your fingers,but you’re using just your palm. You’re gonna put your palm on one side, doesn’t matter becausewe’re gonna do both. And you gonna keep your
mouth and teeth aligned. So the jaw staysin one spot, your teeth stay aligned so they’re not going back and forth like that. You’regonna keep it nice and still and you’re gonna push your palm in that way. And just holdit in place. A nice little 5 second push. Good. See how my jaw’s not actually movingbut I’m just putting gentle pressure on one side. Then after your do that maybe 35 times,5 seconds a piece, then you’re gonna switch and do the same thing on the other side. Somake sure you don’t just do one side and not the other side cause you wanna keep it even.The next one really simply, you’re gonna open your mouth just a little bit and put yourfingers inside but make sure you don’t bite
your fingers. You’re not biting, your keepingagain your jaw still and pushing pressure down this time. So you’re gonna put your fingersin your mouth on your bottom teeth, and just push down. See again my jaw’s not moving.I’m not stretching it open, I’m keeping it in one spot. Again just start off with about5 seconds of gentle pushing and do that about 5 times. The last one is to stretch out thejoin back here. You’re going to put your palm on your chin and just push straight back.Again you wanna make sure that your teeth are in alignment. If your teeth are over hereor over here and your moving it, you’re going to irritate that joint. So just palm on thechin. And relax your jaw. And push straight
back. So those are the exercises to strengthenand stretch out your TMJ joint if you’re having some pain in your jaw. Just start off withabout 5 seconds and then build your way up, but make sure your not pushing too hard. Theseare gentle stretches for that small joint in your jaw.

Temporomandibular Joint TMJ Anatomy and Disc Displacement Animation
The temporomandibular joint 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 is the most used joint in the body. The TMJis essentially the articulation between the condyle of the mandible and the mandibularfossa a socket in the temporal bone. The unique feature of the TMJ is the articulardisc a flexible and elastic cartilage that serves as a cushion between the two bone surfaces.The disc lacks nerve endings and blood vessels in its center and therefore is insensitiveto pain. Anteriorly it attaches to lateral pterygoid muscle a muscle of chewing. Posteriorlyit continues as retrodiscal tissue fully supplied
with blood vessels and nerves.The mandible is the only bone that moves when the mouth opens. The first 20 mm opening involvesonly a rotational movement of the condyle within the socket. For the mouth to open wider,the condyle and the disc have to move out of the socket, forward and down the articulareminence, a convex bone surface located anteriorly to the socket . This movement is called translation. The most common disorder of the TMJ is disc displacement, and in most of the cases, thedisc is dislocated anteriorly. As the disc moves forward, the retrodiscal tissue is pulledin between the two bones.
This can be very painful as this tissue is fully vascular andinnervated, unlike the disc. The forward dislocated disc forms an obstacle for the condyle movement when the mouth isopening. In order to fully open the jaw, the condyle has to jump over the back end of thedisc and onto its center. This produces a clicking or popping sound. Upon closing, thecondyle slides back out of the disc hence another quot;clickquot; or quot;popquot;. This condition iscalled disc displacement with reduction . In later stage of disc dislocation, the condylestays behind the disc all the time, unable to get back onto the disc, the clicking sounddisappeared but mouth opening is limited.
This is usually the most symptomatic stage the jaw is said to be quot;lockedquot; as it is unable to open wide. At this stage the conditionis called disc displacement without reduction Fortunately, in majority of the cases, thecondition resolves by itself after some time. This is thanks to a process called naturaladaptation of the retrodiscal tissue, which after a while becomes scar tissue and canfunctionally replace the disc. In fact, it becomes so similar to the disc that it iscalled a pseudodisc..
