25
causes autogenic inhibition-opposite of muscle spindles, causes relaxation with stretch
golgi tendon
26
nociceptors activate
sympathetic nervous system
27
joints and muscles acting on them have the same nerve supply
Hiltons Law
28
neuromuscular phenomenon that occurs when a joint dysfunction inhibits muscles that surround the joint
arthrokinematic inhibition
29
segments misalign to
proximal segment
30
1 in 3 patients that suffer whiplash will experience
TMJ symptoms
31
TMD affects what percent of the populaton
10-40% of general population
32
How long does it take to decrease TMD pain
at least 4 weeks
33
for every year of TMD, how long under care
1 month
34
TMJ depends on what 3 things
teeth size, position, occlusal surface alignment
35
TMJ Assessment involves
ROM (active, passive, active resisted) | observe deviation, pain, clicks, catches, etc.
36
why should you observe TMJ while seated
gravity and proprioception
37
when checking TMJ fossa, avoid pressing firmly due to
patient sensitivity
38
what are you feeling in TMJ palpation
glenoid fossa
39
finger falling in second is the
involved side
40
side the jaw initially deviates to is
involved side
41
measurement of left and right deviation
>7mm
42
protrusion and retraction measurement is
>6mm
43
on protraction and retraction RMT, what is the side of weakness
side that the mandible deviates to
44
what can be used for bilateral weakness o TMJ
helmet chin strap
45
TMJ is one of the most
muscle imbalanced areas in the human body (chewing on one side)
46
while muscle testing what are we looking for
weakness, failure to "lock"
47
usually side with greater motion is involved side because opposite side disc is
not impeding condyle's forward glide
48
know the 12 signs of TMS
look at packet
49
clenching involves what muscle
temporalis
50
grinding involves
pterygoid
51
what does the pterygoid do to the disc
pulls it forward
52
equal spacing of condyle in fossa means
neutral jaw
53
receeding gums due to
teeth grinding, leads to cavities
54
disc displacement due to
direct trauma intubation dental work big bite
55
long time muscle imbalances due to
chewing on one side AHS sleep posture resting head on hands
56
what can TMJ issues be disguised as
``` ear infection fullness in ear headache, toothache C1 subluxation sinus infection ```
57
superior posterior lateral TMJ
disc moved anterior inferior allowing condyle to occupy space
58
SPL ROM
jaw towards side of involvement until condyle bumps against anterior disc; may click
59
if there is clicking at the end of ROM
do not adjust. hypermobility. fix with exercises
60
TMJ with less than 3 signs/symptoms has
TMD
61
patient with 3 or more signs/symptoms has
TMS
62
SPL jaw LOD
Anterior, inferior, medial
63
pathonomonic sign of anterior inferior condyle (posterior disc)
inability to close the teeth together on side of involvement
64
anatomy of posterior disc/anterior condyle
disc displaced posterior, moving the condyle anterior, limiting closing mechanism
65
symptoms of posterior disc
malocclusion, may have sudden ear pain, can open more than 20 mm, do 2-3x
66
Bruxism mouthguard stages
1. ) teeth guard from drug store 2. ) heat moldable guard 3. ) custom one from dentist
67
acute injury
pain usually on involved side 2-3 months
68
chronic injury
pain is opposite side of problem
69
when should referral be considered
not getting better after 6 visits
70
post adjustment management
avoid foods tough to chew, icing with dixie cup 5 minutes 3x a day, exercises first two weeks twice a day in direction of weakness
71
what muscles should be considered
deep neck flexor weakness and SCM shortness
72
causes of grinding
misalignments, muscle imbalance, stress, parasites, posture, cervical issues
73
what muscles should be checked for shortening
SCM, scalenes, upper traps, masseter, pterygoids, temporalis
