Cervical Spine Hypomobility Flashcards
What are chronic neck pain factors
- 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
Mid and lower C/S and Upper Thoracic spine arhtrokinematics
- 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
OA joint
- 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
Arthrokinematics of OA
- 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
AA joint
- atlas on Axis convex on convex
- AA motion is only rotation
- normal = 45º
Arthrokinematics of
AA joint
- 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)
OA joint during rotation
- 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
Functional side bending
- 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
CS non-functional SB
- 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
C/S protraction mechanics
- extension of upper cervical
- flexion of mid and lower cervical
C/S retraction mechanics
- flexes upper cervical
- extends mid and lower cervical
hypomobility causes
- some people are inherently tight
- post injury/surgery from protection/disuse
Hypomobility can lead to
- 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)
Hypomobility
Presentation
- 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
Hypomobility
Forward head, rounded shoulder posutre consequences
- 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
Hypomobility
CS exam: UQS
- UQS
- additional movements can be added: FB nod, BB nod, SB nod
- cervical repetitive movements; OP if not too acute/painful - protraction & retractions, FB/flexion, extnesion, SB rotation
What to assess with motion for the C/S
- Quantity: normal vs limited C/S ROM or hypermobile
- quality: normal smooth segment recruitment without aberrant movemtns, compenstations
Hypomobility
Facet capsular pattern M/S, LC and UT
with left facet restriction
- FB see deviation toward tight side (left)
- SBR: is restricted - left facet cant upglide
- Right rotation: restricted as left facet cannot upglide
SBL = relatively free
RL relatively free
C/S joint play
- if motion limitied perform mobility testing
- joint play and PPVIM: to asses segmental motion
- normal = a firm stop with an element of creep
- hypomobilty = hard end feel before the expected range
Hypomobility exam
palpation assessment
- C/S facets joints and musculature
- observe and palpate for position and alignment
- palpate for tissue condition - tender facets, swelling/pain, increased muscle tone, guarding, spasm, trigger points, taut bands in musculature
- muscle length/tightness: subocciptials, Upper traps/leator, SCM, Scalenes
Hypomobility
treatment
- STM
- inhibitive distraction
- CS joint mobs
- Upper thoracic joint mobs
- TS thrust for mechanical neck pain
- CS roms, MM stretching
- neuromuscular control
- education.- posture
Clinical prediction rule for neck pain and success with T/S thrust
- no Symptoms distal to shoulder
- symptoms less than 30 days
- looking up down not aggravate symptoms
- score of < 12 on the FABQPA
- decreased Upper T/S kyphosis
- cervical extension < 30º
4/6 = 93% sucess; 3/6 = 86% sucess
