Cervical Spine Hypomobility Flashcards
1
Q
What are chronic neck pain factors
A
- age 40 and up
- coexisting LBP
- Bicycling (drop bars) as a regular activity
- a worrisome attitude
- poor quality of life
- less vitatlity
- loss of strength in the hands
2
Q
Mid and lower C/S and Upper Thoracic spine arhtrokinematics
A
- facets oriented at 45ºangle
- FB: facets slide up and forward
- BB: facets slide down and backward
- SB & rotation: coupled motion and always occur together - ipsilateral facets glide down and back while contralateral facets glide up and forward
3
Q
OA joint
A
- motions here: FB, BB, SB
- Convex occiptial condyles on concave atlas facets
- occiptial condyles - roll and glide opposite
- atlas always glides in direction the occiput moves
4
Q
Arthrokinematics of OA
A
- FB: occiput rolls anterior glide posterior; atlas pressed anterior
- BB: occiput rolls posterior, glides anterior, atlas pressed posterior
- SB: occiput rolls to SB side and glides in; atlas pressed to SB side
5
Q
AA joint
A
- atlas on Axis convex on convex
- AA motion is only rotation
- normal = 45º
6
Q
Arthrokinematics of
AA joint
A
- Axis always rotates in same direction occiput is moving
- during right Rotation: L alar ligament tightens and takes axis into Right rotation
- during SC RSB: L alar ligament tightens and takes axis into RR (alar ligament test)
7
Q
OA joint during rotation
A
- OA joint attempts to keep eyes level
- example: during head right rotation your eyes stay level
- so at OA subcranial Sb opposite SBL occurs to keep eyes level
8
Q
Functional side bending
A
- SB and rotation coupled - occur together ispilaterally go down and back on side rotating to
- ex: functional SB to right = couple motions down and back ipsilaterally (right)
- head/eyes drift a bit downward to right
9
Q
CS non-functional SB
A
- non-functional RSB is strictly in frontal plane
- head does not drift and stay looking forward
- this is due to AA rotation L opposite occurs allowing head/eyes to remain facing forward
- for every degree of functional SB in MC/LC have same degree of AA rotation opposite to keep head/eyes facing forward
10
Q
C/S protraction mechanics
A
- extension of upper cervical
- flexion of mid and lower cervical
11
Q
C/S retraction mechanics
A
- flexes upper cervical
- extends mid and lower cervical
12
Q
hypomobility causes
A
- some people are inherently tight
- post injury/surgery from protection/disuse
13
Q
Hypomobility can lead to
A
- adapative shortening - adhesions ‘loss of segmental motion
- degeneration of synovium
- nutrition of the disc reduced
- disuse atrophy of musculature
- liability to further injury
- developement of DDD, DJD (start DD=> DJD)
14
Q
Hypomobility
Presentation
A
- Limited CS A&PROM
- stiffness, tightness
- increased resistance at end range
- hard to turn/requiring more effort as approach end range
- pain at end range
- CS joint play & PPIVM restricted
- habitual FWD head posture leads to Hypomobility UC
15
Q
Hypomobility
Forward head, rounded shoulder posutre consequences
A
- tight suboccipital muscles cervicogenic headache
- flexion MC/LC stresses to posterior annuls disc = HNP
- DDD => cervical stenosis (spondylosis)
- Stiff U/T spine with dowagers hump kyphosis
- jaw drops/retracts = TMJ pain
- tight pecs; scalenes => elevation of 1st rib => Thoracic outlet syndrome
- shoulder impingement syndrome
