TMJ Flashcards
What muscle stabilizes the disc in the TMJ
lateral pterygoid
How do we instruct a patient to perform a opening MET-agonist
Have pt give a 10% contraction attempting to open mouth wider
after 8 seconds the pt relaxes then takes a deep breath and yawns to stretch further
now the PT takes the patient further into opening and hold for 8 seconds while breathing
repeat
How to we instruct a pt to perform an opening MET-antagonst
Instruct pt to give light contraction to close
after 8 seconds the pt takes deep breathe and performs yawn
now PT stretches them into further opening, hold for 8 seconds while breathing
repeat
The __________ temporalis and masseter perform lateral deviation
the ________ medial and lateral pterygoid perform lateral deviation
ipsilateral
contralateral
How do we perform an agonist suboccipital MET?
Suboccipitals do ext, so therefore we are USING them in an agonist MET in order to STRETCH THE SAME MUSCLE we are using and improve flexion
Pt looks up with Cv ext against resistance (“look up with your eyes”
Now pt looks down with eyes (no resistance)
perform _________ before all TMJ mobilizations
distraction
What is the main muscle of protrusion at the TMJ?
lateral pterygoid
What is the optimal resting position of the mouth?
Tongue up, teeth apart, lips closed
TUTALC
how can you progress TUTALC for a patient
can progress to lips apart and keep tongue on roof of mouth
What are 3 exercises for suprahyoid facilitation
Tongue roll opening- Insruct pt to slowily open mouth while rolling tongue along palette towards the throat
N exercise- Open mouth and say the N sound while depressing the jaw (dont move cervical spine)
Tongue clicking
What TMJ exercise is good for forward head posture and tongue resting position
Tongue clicking
How can we cue the patient to get in the correct position for the tongue clicking exercise
Say “N”
How can we train a pt to have a normal opening pattern at the TMJ
Progression in order:
- Manually facilitate proper opening in front of mirror
- Provide tactile cues in front of mirror
- No tactile cueing, just visual feedback from mirror
- now have them open without being infront of mirror
How can you train lateral excursion strength
have patient bite down on stack of tongue depressors held together by rubber band and slide mandible side to side
Note: also works for protrusion/retursion if you slide forward and back
How to strengthen unilateral closing?
have pt bite down on stack of tongue depressors
How do you perform an antagonist MET for L lateral excursion
Bring pt to maximum L lateral excursion
Resist R lateral excursion from this point, 10% contraction for 5-10 seconds
Bring pt further into L lateral excursion
How do you perform an agonist opening MET?
have pt depress jaw to pain free barrier
resist pt on an isometric contraction into FURTHER OPENING, 10% contraction for 8-10 seconds
have pt perform yawn and relax into new barrier
How do you perform an antagonist opening MET
have pt depress jaw to pain free barrier
resist pt on an isometric contraction into CLOSING, 10% contraction for 8-10 seconds
have pt perform yawn and relax into new barrier
Which lateral pterygoid is performing L lateral excursion?
R lateral pterygoid
