1

opening pattern for DDwR deviation

 

C

1

What can be a RED flag in TMD patients?

 

Impairment of cranial nerves

2

J opening pattern

 

DDwoR deflection

2

Goal of active exercise for TMD:

to maintain midline position of mandible while increasing motion

2

What should be cleared when assessing TMJ

 

Cranial nerves and C-spine

3

TMJ OA joint feel/sounds

 

Hard/cracking clicks or noises throughout motion

4

TMJ opening pattern for muscle dysfunction/imbalance deviation

 

S

4

ptosis

 

drooping eyelid

a sign of impaired cranial nerves

6

TMJ: What do clicks imply?

 

abnormal movement between condyle, disk, and mandible

7

Impairment of cranial nerves indicates what in TMD pts?

 

RED flag

8

how can you quickly assess TMJ opening/depression?

 

Knuckle Test

9

Explain two clicks in DDwR

 

  1. Click One: Patients can have a single click that occurs during opening
  2. Click Two: If they have a second click (aka reciprocal click), it occurs during closing. It may need to be auscletated to be heard.

opening pattern for DDwoR deflection

 

J

11

TMJ: late clicking implies ______

 

a chronic problem

 

12

TMJ: How does mandible move during deviation?

  1. Mandible will pivot around restricted joint,
  2. deviation is to side of restricted joint.

13

facial palsy

 

drooping of the corner of the mouth

A cranial nerve impariment symptom

15

Describe DDwoR

Can have Closed lock or Open Lock:

  1. Closed lock (can't open). Condyle is posterior to disk
  2. Open Lock (can't close), 2 clicks on opening as condyle moves anterior to disk (onto disk, off other side)

16

TMJ Functional Opening

~30mm

17

Five common findings of cranial nerve impairment:

 

  1. Tinnitus
  2. ptosis
  3. facial palsy
  4. difficulty swallowing

19

TMJ: Early clicking implies _______

a developing problem

 

20

Primary goal for TMD intervention:

 

Restore normal opening

22

TMJ Normal opening

 

50-60mm

23

The 3 Hallmarks of TMD:

  1. orofacial pain
  2. restricted jaw opening
  3. joint noise

24

C pattern upon opening (TMJ)

 

DDwR deviation

25

Explain single click in DDwR

Patients can have a single click that occurs during opening.

 

26

TMJ: S pattern of opening

Muscle dysfunction/imbalance deviation
