(90 cards)
1
Q
What are risk factors for atraumatic neck pain?
A
- female sex
- prior hx of neck pain (50-85% experience recurrent neck pain within 1-5 yrs of an episode)
- potentially: older age, higher job demands, hx of smoking, low social support, prior hx of LBP, stress & anxiety
-older age and hx of other MSK disorders predicted greater chronicity
2
Q
What’s the prognosis for atraumatic neck pain?
A
- younger people have better prognosis
- poorer health with a modest effect on prognosis
- initial evidence suggests: general exercise at baseline is NOT related to prognosis, but one study suggests regular cycling may WORSEN prognosis
3
Q
What are WORSE prognoses linked to for for atraumatic neck pain?
A
worse prognosis linked to:
-poor psychological health
-lower social support and passive coping strategies
-low workplace control decision making
4
Q
What’s the prognosis for cervical radiculopathy?
A
favorable outcome usually regardless of intervention
- 75-90% good improvement w/o surgery
- pain, sensory deficit, and OBJECTIVE WEAKNESS used as decision to operate
- no clear evidence of better long-term outcomes with any intervention though specific populations may benefit from surgery
5
Q
What’s the prognosis for TRAUMATIC neck pain (WAD/whiplash associated disorder)?
A
- 42% mild problems with rapid recovery
- 40% moderate problems with incomplete recovery
- 17% severe problems without recovery
-trajectory not impacted by collision factors
6
Q
What’s the prognosis for CHRONICITY of traumatic neck pain?
A
Within 6 weeks of trauma, 5 factors predict chronicity of pain:
- Pain intensity >6/10 (pain severity)
- NDI >30% (disability/function)
- Pain catastrophizing scale >20 (pain catastrophizing)
- Impact of Events Scale - Revised > 20 (post-traumatic stress response)
- Cold hyperalgesia (multiple ways of assessing)
7
Q
What’s the prognosis for chronic disability in WAD?
A
Predictors of chronic disability in WAD are:
- high level of baseline disability
- self reported psychological distress
- passive coping strategies
- predicted recovery >6 months
- 6+ physical symptom complaints (e.g. pain, numbness, head feels heavy, dizziness, etc)
8
Q
What’s the primary movement of the O-C1 joint?
A
craniocervical flexion (nod)
9
Q
What’s the primary movement of the C1-C2 joint?
A
mainly cervical rotation
10
Q
What’s the coupled motion in the lower cervical spine?
A
C/S sidebend and ipsilateral rotation
- this closes the intervertebral foramen and extends (closes) the facet joint
11
Q
How do you test the facet jt?
A
with uncoupled motion- this takes away (opens) the intervertebral foramen. will feel stiff b/c it’s not the normal mechanics
ex: sidebending and contralateral rotation
12
Q
What anatomical variation of the cervical spine are children born with?
A
Children are born w/o uncinate processes and uncovertebral joints until ~9 years old
uncovertebral jts are distinct by ~33 y/o
13
Q
What percentage of asymptomatic people age 65+ have cervical DJD?
A
57%
- evidence of DJD on imaging doesn’t equal pain
14
Q
If imaging shows DJD/OA in people age <20, is this normal, and what would you suspect?
A
Abnormal. Suspect trauma (e.g. sports, child abuse, landing on head [gymnastics], sports that involve falling].
Or there could be hypermobility (EDS, Down Syndrome)
15
Q
Does pathology on imaging equal presence of pain or pain source?
A
no
16
Q

what is degenerative disc disease (DDD)?
-anatomic/structural changes within an intervertebral disc (IVD) causing a loss of function
-occurs naturally with aging, not always assoc. w/ pain
-loss of H2O content in nucleus and decreased disc height --> decreased space at intervertebral foramen + increased stress at facet jts --> higher potential for DJD and radiculopathy
61
what is DJD?
facet osteoarthritis (DJD)
-involves facet arthropathy and osteophytosis, can develop due to DDD
-pain is thought to be d/t cartilage destruction and decreased joint space
-pain can be local or referred to the proximal upper quarter
OA pattern: stiff in AM and after a period of immobility; worse pain in AM -> better midday-> worse by end of day
62
what is spondylolisthesis
slippage of one vertebra on another
-degenerative: most common type, due to DDD/DJD
-often presents with sxs of spinal stenosis/radicular or myelopathic sxs

Over 100% is Spondyloptosis, when the vertebra completely falls off the supporting vertebra
64
what is spinal stenosis? what is it typically caused by?
spinal stenosis= clinical diagnosis (Vs. only radiological finding) involving symptomatic narrowing of the spinal canal or intervertebral foramen causing pain and/or neuro sxs in the extremities
-typically caused by spondylosis (DDD/DJD with ligamentum flavum hypertrophy) or spondylolisthesis

greater likelihood of healing with a more severe injury
68
imaging does or does not always correlate with clinical outcome
does not
69

Persistent regional neck pain w/ trigger points.
-think of common muscles w/ trigger points
-often limited in ROM
-trigger pts can refer pain to the upper quarter
75
what is cervical dystonia?
SCM causing pain due to spasm or spasticity
-presents as anterior/lateral neck pain, often with rotated/tilted position of the head
-painful form of torticollis
76
what other joints can refer pain into the neck?
TMJ, shoulder, thoracic spine
77
what are some recommended patient recorded outcome measures for neck pain?
NDI (validated in many languages);
PSFS;
McGill Pain Questionnaire; Oswestry for axial pain;
outcome measures for yellow flags;
consider using Radar plot for pain domains
78
characteristics of Neck Pain with Mobility Deficits
-primarily motion limitations in cervicothoracic spine related to joint or muscle stiffness
-NO radiating pain or trauma, likely cntral or unilateral cervical pain that pay or may not refer to shoulder and upper quarter but NOT into the distal UE. should have (-) neuro screen.
-sxs usually elicited by A/PROM and/or segmental testing (PAIVMs, PPIVMs, up/downglides, lateral glides)
-may have weak neck and scapular muscles if condition is subacute or chronic
79
what's a helpful special test for neck pain with mobility deficits?
cervical rotation lateral flexion (CRLF)
(if 1st rib is elevated, it'll feel stiffer/blocked)
-The test is performed with the patient in a sitting.
-The cervical spine is passively and maximally rotated away from the side being tested.
-While maintaining this position, the spine is gently flexed as far as possible moving the ear toward the chest.
-A test is considered positive when the lateral flexion movement is blocked.
80
what are characeristics of Neck pain with movement coordination impairments?
-whiplash or traumatic onset
-pain primarily related to motor control issues
-neck pain, shoulder girdle pain or referred UE pain, dizziness, nausea, concussive sxs, HA, difficulty concentrating, light sensitivity, heightened affective distress, general hypersensitivity to stimuli
-reduced mm recruitment in C/S and shoulder girdle, degeneration of posterior cervical mm; proprioceptive deficits, sensory hypersensitivity or reduced pain thresholds, psychosocial disturbances-- depression, anxiety, fear of mvmt
81
What are helpful special tests for neck pain with movement coordination impairments?
1. craniocervical flexion test (the one with the BP cuff),
2. neck flexor muscle endurance test (chin tuck + lifting head up an inch, then holding),
3. pressure pain threshold (uses a digital pressure algometer)
--use for allodynia or hyperalgesia, central sensitization
--lower thresholds locally -> local mechanical sensitivity
--widespread lower thresholds -> suggest central nociceptive processing disorder [central sensitization]
82
What is the norm for the neck flexor muscle endurance test for people with neck pain, and people without neck pain?
Norm for ppl w/ neck pain: 24.1 sec
Norm for ppl w/o neck pain: 38.95 sec
83
What are characteristics of neck pain with cervicogenic headache?
-Intermittent, UNILATERAL "ram's horn" presentation from occiput to temporal region
-related to changes in mvmt of the neck and jaw

84
What's the diagnostic cluster for neck pain with cervicogenic HA?
-Decreased cervical AROM
-Impaired craniocervical flexion test
-Provocative and/or hypomobile PAs Occiput-C3
85
What's a helpful special test for diagnosing neck pain with cervicogenic headache?
cervical flexion-rotation test (highest specificity)
-pt is supine
-you flex their neck (hold with your hands & belly)
-rotate to one side, then the other
-inclinometer/goni to measure
86
What's a positive cervical flexion rotation test?
either < 32 deg of rotation, or a 10 degree reduction when comparing side to side
-note: if ROM >45, pt likely came out of flexion or started to sidebend
87
What are characteristics of neck pain with radiating pain?
Pain or parethesias that radiate to DISTAL UE or medial scapular border
-neuro screen (DTRs, myotomes, dermatomes C5-T1): not great at determining location of disc herniation, but tells us if there's generally a nerve root compromise
-Valsalva maneuver (increased sxs with cough/sneeze)
88
what's the diagnostic cluster for neck pain with radiating pain?
-Cervical rotation <60 deg on affected side (specific)
- (+) ULTTa (most sensitive)
- Positive Spurling's (specific)
- Positive distraction (specific)
- 4 of 4 = 90% post-test probability
- 3 of 4 = 65% post-test probability
89
describe/practice the ULTTa. what is a positive test?
1. prevent scapular elevation (block it)
2. shoulder ABD 90 deg + elbow flexion
3. forearm supination, wrist and fingers extension
4. shoulder ER
5. elbow extension
6. contralateral and then ipsilateral sidebending of neck
Positive test:
1. reproduce sxs
2. side to side difference >or = 10 deg in elbow or wrist
3. contralateral SBing increases sxs
4. ipsi SBing decreases sxs
