Msk TMJ And cervical Flashcards
What are the three ligaments of the temporomandibular joint?
1-lateral ligaments ( helps restrain the jaw mov)
2-stylomandibular lig
3-sphenomandibular lig
What are some signs/symptoms of Osteoarthritis of the TMJ?
Degenerative changes
Diffuse pain
Decrease ROM
Stiffness on waking
Atrophy and weakness of mm of mastication
Crepitus
What are some signs/symptoms of disc displacement with reduction of the TMJ?
- Clicking w movement
- Double click:
1- reduction of disc
2-dislocation of disc
-anterior disc displacement most common
What are some signs/symptoms of disc displacement without reduction of the TMJ?
Jaw does not full open or fully close
How is the jaw Closed lock?
Locking on opening. Jaw cannot fully open more then 30mm. ( normal is 50mm)
Anterior displacement of disc
How is the jaw Open lock?
Locking on closing. Jaw can not close
Posterior displacement of disc
What is the sign for Hypomobility syndrome of TMJ?
Deviation towards affected side -ipsilateral
Decreased ROM
Signs of contracture
What is the sign for Hypermobility syndrome of TMJ?
Increased ROM
Pain w opening
Deviation towards unaffected side (contra lateral)
Noise at end range
What are the TMJ normal values for
Functional opening:
Maximal opening:
Lateral deviation:
Protrusion:
Retrusion:
Functional opening: 40mm
Maximal opening:50mm
Lateral deviation:9mm
Protrusion:9mm
Retrusion:1-2mm
What is the special test for functional opening of the Jaw?
The “ Knuckle test”.
Functional opening =2 flexed prox interphalangeal joint within open mouth
Maximal opening =3 flexed prox interphalangeal joint within open mouth
Positive test: if there is inability to fit the fingers
What are some interventions for TMj?
Education
Fascial m relaxation
Tongue proprioception and control
Jaw proprioception and control
Strengthening (can do isometric)
Manual therapy
Modalities ( us,laser,tens)
How is the joint manipulation technique for Anterior displacement disc?
Pull jaw down and foward
How is the joint manipulation technique for Posterior displacement disc?
Pull jaw down and back
How many cervical vertebrae?
How many nerve roots we have in the cervical?
How many intervetebral discs we have in the cervical?
7 cervical vertebrae
8nerve roots (c1-c8) nerve roots exit ABOVE the corresponding disc
6 intervertebral discs. No disc between C0-C1 and C1-C2.
What is cervical radiculopathy?
Group of signs and symptoms related to a compressed or irritaed nerve root.
Why should u test the dermatome or myotome?
If u wanna rule out nerve compression
How is performed the dematome procedure?
-area to be tested has to be exposed
-test an unrelated body party (face/leg) to check pt understanding
-ask pt to close eyes
-test the entire dermatome,proximal to distal
-test bilaterally at the same time
-start with light touch and if impaired progress to test with sharp/dull or cold/hot
Which muscles are activate when your jaw deviates to the LEFT?
Contralateral: pterygoides
Ipislateral: masseter and temporallis
So jaw deviate to Left side is left masseter and temporalis and right pterygoids.
Jaw deviation and muscles…
Contralateral of deviation: pterygoides
Ipislateral: masseter and temporallis
How to test the myotome?
To test the muscular function.
-pt is positioning usually sitting
-PT position joint to be tested in neutral position
-“hold this position and don’t let me move u”
-PT applies manual resistance for 5-8seconds while pts resists movement
-test bilaterally whenever possible
What is the position to test the Myotomes for C1-C2?
C1-C2: neck forward flexion
