Lecture3 Flashcards
What percent of adults have TMD?
40-60%!!!
If the muscle is LATERAL to the joint, in which way is the deflection?
TOWARDS the involved muscle
Latowards!
If the muscle is MEDIAL to the joint, in what way is the deflection?
AWAY from the involved muscle
what is protective CO contraction?
movement to protect that area
CNS has identified what movement to avoid
The problem with this- the tolerance to this becomes LESS, then you’re crying. Decreases ability to tolerate that pain
Muscle splinting is another way to say it.
Patient will say their muscle seems to tire quickly.
What is myofascial pain?
VERY COMMON
Chronic pain for more than 6 months. The muscles have been triggered and are sore. THEY can be acute or chronic trigger points. The exact nature of those trigger points is not known
Describe the spray and stretch technique?
spray with a vapocoolant and lightly stretch them out!
what is a good way to ease trigger points?
18 inches away ish- Spray and stretch technique
Describe disc displacement- does the patient have normal range of motion?
yes, so the disc is elongated, the lateral pterygoid pulls a little more. When you open , you get a click, but it’s the same range of opening
You have thinning of the posterior segment
Describe disk location with reduction?
- Clicking and “catching sensation” GENERALLY just one click.
- LIMITED range of opening unless there is reduction.
- Loud pop might be heard when recapturing the disc
In what situation do you have a SINGLE click?
disk location with reduction
if you have limited opening of only 25-30 mm, normal movement on the ipsilateral side but restricted on the contralateral side what is happening?
Disc dislocation WIHTOUT reduction
Typically they have one side LOCKED and they go sideways and can’t go any further.
Loading of the joint with bilateral manipulation would be PAINFUL
Describe predispsing TMD factors of the articular eminence
-steepness of the posterior slope= MORE steep = greater condyle disc movement which can increase the risk of ligament elongation that leads to DDD
Describe the morphology of condyle and fossa that can lead to TMD
- Joint- quality of ligaments
- Females report more TMD an have more flexible joints that men cuz of estrogen.
- Attachemnt of the superior lateral pterygoid muscle. (if it’s attached more to the disc, then it can pull more**
So remember, the superior lateral pterygoid helps in closure?
**if the superior lateral pterygoid spasms, it will pull on the disc
T/F
If more muscle is attached to the neck of the condyle, less disc displacemetn tends to occur?
true
T/F If more muscle is attached to the DISC, more disc displacement tends to occur?
true
