Q

kinetics

A

TMJ, teeth and c-spine are intimately related

cervical posture affects mandibular path of closure

  • FHP=posterior occlusion
  • retracted c-spine= anterior occlusion

Q

closing

A
  • reverse of opening
  • *also 2 phases

posterior translation in superior joint space
-disc pulled back by tension in superior retrodiscal lamina, posterior fibers of temporal is; controlled by eccentric lateral pterygoid

rotation in inferior joint space
-muscles of mastication

17
Q

exam and eval subjective

A

onset of symptoms

incidence of joint locking-open or close

presence of joint noise

  • joint click hallmark of disc derangement
  • click on opening
  • click on closing

history of surgery

pain (intensity, frequency, location)

outcome measure
-TMD disability index

18
Q

pain examination (palpation)

A

mandible, hyoid, TMJ
-palpate posterior TMJ and capsule (through ear)-tender w/ swelling

relevant joints of upper quadrant, cervical and upper thoracic spine

muscles

relevant trigger points and tender points

19
Q

mobility impairment exam

A

active and passive physiologic ROM of cervical and thoracic spine

TMJ: A/PROM- vertical opening, lateral excursion, protrusion

TMJ translation and rotation SYMMETRY!!

joint play assessment (distraction, medial and lateral glide, compression)

muscle tests (length, test, control)

mobility of nervous system (if indicated)

20
Q

classification of TMDs

A
  • capsulitis/synovitis
  • capsular fibrosis
  • disorders of the muscles of mastication
  • hypermobility
  • anterior disc displacement w/ reduction
  • anterior disc displacement w/out reduction
21
Q

capsulitis/synovitis S/S

A

=micro/macro trauma

  • tender to palpate lateral condyle or post compartment
  • pain w/ contralat biting
  • pain w/ retraction OP
  • pain w/ end range accessory motion testing
22
Q

capsulitis/synovitis Rx

A
  • ionto (dex or xylocane)
  • manual therapy (STM, non-thrust mobs)
  • postural and TMJ proprioception ex
23
Q

capsular fibrosis

A

=chronic inflammation, trauma, immobilization, entrapped disc

24
Q

capsular fibrosis S&S

A
  • typically <25mm opening
  • limited accessory motion
  • no joint sounds
  • ipsilateral deviation of mandible when opening
25
Q

capsular fibrosis Rx

A
  • heat
  • TMJ mob/manip, prolonged stretching
  • AROM, proprioception exercise
26
Q

disorders of muscles of mastication

A
  • commonly tendonitis of temporalis muscle

* overuse

27
Q

mastication muscle disorder S/S

A
  • painful to palpate muscles (TrP may be present
  • possible alteration in mandibular active control
  • parafunctional oral behaviors
  • pain w/ ipsilateral biting
28
Q

mastication muscle disorder rx

A
  • heat
  • controlled opening/closing muscle re-ed
  • intraoral and extraoral STM
  • pt ed., activity mod (gum chewing, grinding)
29
Q

hypermobility

A
  • opening >40 mm w/ click at end range opening
  • can be asymptomatic
  • collaterals loosen
  • hypothesized pre-cursor to disc displacements
30
Q

hypermobility S/S

A
  • excessive opening ROM

- hypermobility noted on accessory motion exam

31
Q

hypermobility rx

A

avoid end range positions

  • tongue on roof of mouth-yawning
  • avoid taking large bites

exercise

  • proprioception
  • stabilization
32
Q

articular disc displacement w/ reduction S/S

A

=laxity in collaterals and retrodiscal lamina

  • pain if recent dysfunction
  • abnormal mandibular motion maybe
  • on closing, disc does not come back and condyle slides posteriorly-click
  • on opening, the condyle re-captures the disk-click
33
Q

articular disc displacement w/ reduction rx:

A
  • TMJ mob
  • STM
  • posture ROM, isometric stabilization exercises
  • splints
34
Q

articular disc displacement w/out reduction

A

=history of disc displacement w/ reduction (joint clicks)

  • disc remains displaced anterior to condyle
  • opening <25mm, ipsilateral deviation
35
Q

articular disc displacement w/out reduction rx

A
  • TMJ mobs
  • c-spine mob/manip
  • posture, c-spine exercises
  • pt ed (soft foods, parafunctional habits, tongue resting position, relaxation, activity mod)
36
Q

TMJ OA

A

often accompanied by disc perforation

=joint pain and crepitus

37
Q

TMJ OA rx

A
  • TMJ mobs
  • A/PROM
  • STM
  • postural exercises
38
Q

proprioceptive exercises

A

rubber rube

phase 1: active lateral deviation away from painful side

phase 2: lateral deviation, bite for 5 sec, release, return

phase 3: lat dev, bite and maintain to return

phase 4: protrusion

phase 5: protrusion, bite, relax, return

phase 6: protrusion, bite and maintain to return

final: gently pull tube (resist protrusion and lat dev)

39
Q

rocabodo’s 6x6

A

6 exercises
6 reps
6x/day

1: tongue rest and nasal breathing
2: controlled opening
3: rhythmic stabilization (isometric)
4: craniocervical flexion (nod)
5: cervical retraction
6: shoulder retraction (retract and depress)

40
Q

hypermobility

A

head and/or ice if condition is painful

muscle performance:

  • TMJ rotation and translation control
  • proprioception, strengthening and stabilization exercises
  • isometric or static exercises initially
  • progress to dynamic and functional exercises
