Cervical Spine Examination and Intervention

Daemen College DPT Program

2

Objectives

• Review the anatomy, biomechanics, and arthrokinematics of the cervical spine.

• Introduce a sequence of examination tests and measures designed to arrive at a patient classification for cervical spine disorders.

• Analyze patient responses to repeated end range cervical motions to determine appropriateness of exercises based on direction of preference.

• Evaluate the cervical spine to determine the presence of hypermobility and instability.

• Apply appropriate exercise and manual physical therapy interventions designed to improve cervical spine mobility, stability, and function

3

Cervical Spine Examination

• History/Subjective• Structural • AROM• Repeated movements• PROM (PIVM)• Muscle performance

– deep neck flexor strength and endurance, muscle balance tests

• Neurological – dermatomes, myotomes, muscle stretch reflexes, neurodynamic testing

• Palpation• Special tests

4

Subjective Examination

• Area• Nature • Behavior • Mechanism of injury• Duration• Review of systems• Functional limitations/perceived level of

function

5

Neck Disability Index

• Vernon H, Mior S.• A modification of the Oswestry Low Back Pain

Index• Test-retest reliability was conducted on an initial

sample of 17 consecutive whiplash patients (r=0.89, p,>05)

• Concurrent validity was established through comparing NDI scores with McGill Pain Questionnaire (correlations 0.69-0.70)

6

Differential Diagnosis

• What is the first order classification?

• Is the patient’s condition warrant referral to another medical professional?

• What further tests/measures are indicated?

7

Medical Diagnosis Examples

• ICD – 9 – CM– 724 – unspecified disorder of the back– 839.0 – dislocation, cervical (closed)– 847 – sprains and strains of parts of the back

8

Associated with Spinal Disorders – Pattern 4F

9

Connective Tissue Dysfunction – Pattern 4D

10

Structural Examination

• Detailed examination of alignment and structure from anterior, posterior, lateral views

• Head tilt, torticollis• Examination of sitting posture• Correlation of symmetry to back pain –

Levangie PK. The association between static pelvic asymmetry and low back pain.

Spine. 2000;2551-2552.

11

AROM

• Quality and quantity of movement through goniometric measures and observation of quality of movement

• Flexion

• Extension

• Sidebending

• Rotation

12

Cervical Spine Repeated Movements

• Protraction• Retraction• Retraction with extension• Above testing in

weightbearing• Baseline prior to each

test movement• PDM or ERP• Deviations

• Retraction• Retraction with extension• Above testing in supine• Baseline prior to each

test movement• PDM or ERP• Deviations• Repeated sidebending

and repeated rotation tested in sitting if no effect from saggital plane movements

13

Assessment of patient responses to repeated movements

• Increased• Decreased• Increased/no worse• Decreased/no better

• Centralized• Peripheralized • Worse• Better• No effect

14

Neck Retractions, Cervical Root Decompression, and Radicular

Pain• Abdulwahab SS, Sabbahi M. JOSPT.

2000;30:4-12.

• Neck retractions appeared to alter H reflex amplitude. These exercises may promote cervical root decompression and reduce radicular pain in patients with C7 radiculopathy

15

Reliability of McKenzie Classification of Patients with

Cervical or Lumbar Pain• Clare HA, Adams R, Maher CG, J. Manipulative Physiol Ther. 2005; 28:122-127.• The reliability for syndrome classification was

k=0.84 with 96% agreement for the total patient pool, and k=0.63 with 92% agreement for cervical patients.

• The reliability for subsyndrome classification was k=0.87 with 90% agreement for the total patient pool, and k=0.84 with 88% agreement for the cervical patients

16

PROM

• Assessment of end feel (may avoid end range rotation in certain patients)

• Flexion • Extension• Sidebending• Rotation• What are the normal end feels for the cervical

spine?• What tissues are placed on stretch with

assessment of the end feel?• Are other passive tests indicated?

17

Passive intervertebral motion testing (PIVM)

• Also referred to as single segmental mobility testing (SSMT)

• Flexion, extension, sidebending, rotation in weightbearing and nonweightbearing positions

• Palpation between or lateral to spinous processes

• Poor to moderate kappa coefficients – cervical (Fjellner et al., 1999, Smedmark, Wallin, Arvidsson, 2000).

18

Lateral mobility, A-P, and P-A Tests

• Lateral mobility also referred to as position testing

• Lateral translation (sidegliding) in neutral, flexion, extension

• A-P segmental mobility

• P-A segmental springing from prone

19

Muscle Performance

• Isometric resistive testing

• Specific Manual muscle tests

• Muscle performance – strength and endurance of the deep neck flexors

20

Neurological testing

• Dermatomes

• Myotomes

• Muscle stretch reflexes

• Tests for Adverse neural tension

21

Adverse neural tension testing

• Upper limb tension tests (ULTT) – median, radial, ulnar

• Brachial plexus tension test

• Elvey test

22

Neurodynamic testing

• Based on adverse neural tension test

(Brachial plexus stretch, Elvey’s)

• Assess upper cervical flexion mobility for range and reproduction of symptoms

• Return to cervical neutral and place patient in Elvey’s position

• Reposition patient in upper cervical flexion and observe response.

23

Special tests

• Compression• Foraminal compression• Distraction• Vertebral artery• Quadrant test• Tests for space occupying lesion Valsalva, DeJorines Triad (coughing,

sneezing, straining)

24

Palpation

• Tissue texture abnormalitiesSkin rollingSkin puckeringToneLigamentous tenderness

• Positional faults, symmetry

25

Palpation

• Articular pillars

• Spinous processes

• Transverse processes

• External occipital protuberance

• Soft tissue tone

26

Assessment/Diagnosis

• Positive findings with repeated movements may indicate derangement

• Positive findings with passive movements may indicate joint

• Positive findings with resistive movements may indicate a muscle lesion

27

PT Diagnosis

• Musculoskeletal practice pattern?

• Acute/subacute/ chronic?

• Postural• DysfunctionHypomobilitySoft tissue

dysfunction• Hypermobility

• Derangement (centralizers vs. noncentralizers

AnteriorPosteriorPosterolateralFar lateral• Muscle length/

strength• Myofascial

28

Classification

• Postural

• Derangement

• Dysfunction

• Joint dysfunction

• Muscle lesion

• Ligamentous sprain

• Hypermobility/instability

29

Cervical Derangements

• #s 1-6 are posterior• #s 1,3,5 no deformity• #s 1,2 central/symm• #s 2,4,6 deformity

#2 – acute kyphosis

#4 – torticollis

#6 - torticollis

#5,6 pain below elbow

• Goal is to get patient to perform retraction in sitting throughout day

• May need to utilize

nonweighting retraction and extension, sidebending, rotation

30

Treatment of derangement

• Postural correction

• Exercises in direction of preference

• May begin in weightbearing or non-weightbearing position

• Recovery of function

31

PT Intervention

• Intervention directed toward patient classification• Postural syndrome – postural correction• Derangement – exercises according to direction of

preference• Dysfunction – passive stretching, soft tissue mobilization• Adverse neural tension - neuromobilization• Hypomobility - manual physical therapy• Hypermobility – cervicial spine stabilization• Muscle lesion – muscle re-education, therapeutic

exercise• Manual or mechanical traction

32

Manual Physical Therapy

• Risk vs. Benefit in cervical spine (Rivett, DiFabio)

• Progression of patient generated forces (McKenzie)

• Grades of mobilization I-IV (Maitland)

• PACVP• PAVP• TVP• High velocity thrust Safe practice through

Premanipulative testing, Grades of mobilization, Positioning (Meadows), Component technique (Hartman)

33

Upper Cervical Spine Examination

• Subjective• Functional questionnaire

– Neck Disability Index (NDI)

• Gait analysis• Structural exam• AROM - midcervical quality of motion quantity of motion

• Repeated movements – midcervical

• If no effect: • AROM – upper cervical• Passive intervertebral

motion – upper cervical• Motor performance• Neurological• Palpation

34

Examination of upper cervical spine

• Presence of upper cervical pain, headaches, trauma

• Failure to respond to cervical spine examination

• Association with TMD

35

43

Assessment of deep neck flexors

• Strength: Cranio-cervical flexion test Pressure biofeedback unit inflated to 20 mm,

testing at initial pressure of 22 mm held for 10 seconds (Jull et. al., 2000).

(Krout and Anderson, 1966, Childs et. al., 2003)

44

Initiation of Guidelines

• Hypomobility vs. Hypermobility

• Vestibular component of treatment

• Cervical component of treatment

• Initiation of standardized outcomes

• Evidence-based

• Retrospective analysis
