Movement Impairment Diagnoses
of Cervical Spine
Extension
Rotation
Flexion
Rotation-extension
Rotation-flexion
Treatment directed at
adjacent regions for neck pain
Adjacent regions critical to consider – examination of patient
with neck pain:
1. Alignment of the thoracic spine, scapulothoracic joint.
2. Weight of the upper extremities and their affect on
cervical rom and pain.
Van Dillen LR, et al.. Clin J Pain. 2007
Andrade GT et al. JOSPT. 2008
3. Movements of the upper extremities and how they
affect compensatory movements at the neck

• The syndrome is identified by the direction of
the movement that most consistently is
associated with pain.
• Correction of the movement decreases or
eliminates the symptoms.
Dx & Tx Premise
• Deviations in cervical spine alignment and
movement patterns from the normal
standards contribute to microtrauma and
eventually to macrotrauma.
• Deviations are induced by repeated
movements and sustained postures that
alter the participation of muscles and the
support provided by joint structures.
Normal Cervical Spine Alignment
• Inward curve
• Influenced by length
– intrinsic muscles of
cervical spine
– muscles of shoulder
girdle that attach to
cervical spine
• Alignment of the
thoracic spine
Kendall et al 1993

Alignment
Common Impairments
• Intrinsic neck muscles become weak or long compromise fine control of vertebral motion
• Extrinsic muscles become dominant adding to
compressive, rotational, & shear forces
exerted on the cervical spine
Treatment: Correcting Thoracic Flexion
> improves cervical alignment
Black et al. Spine.96
Neck Flexors
• Intrinsic muscles
• Longus capitis
• Longus colli
Deep Neck Flexors
Impairment

the deep neck flexors

• Pure sagittal
rotation

 Common muscle
impairment in patients
with neck pain
DeRosa & Porterfield
Poor performance of
deep neck flexors
Deep Neck Flexors Impairment
Implications for treatment
• Weakness of the deep neck flexors
results in translation of cervical spine
• Dominance of Sternocleidomastoid and
Anterior, Middle Scalene
Poor performance of
deep neck flexors
• Translation greater than sagittal
rotation
Forward head with increase
upper thoracic flexion
Flexion – lower spine remains
extended

Head and Neck Extensors
Intrinsic muscles

semispinalis cervicis
pure sagittal rotation
Head & Neck Rotators/extensors
• Intrinsic muscles
• semispinalis cervicis
• superior oblique
inferior oblique
• rectus capitis
cervicis
Attached to C2
DeRosa & Porterfield
Splenius & Levator Scapulae
DeRosa & Porterfield
Neck Extensors - Extrinsic
• Rotate head
• Upper Trapezius
• Extend neck
• Levator Scapulae
and neck to
same side
– Cervical spinous processes to scapula
– Cervical transverse processes to scapula
DeRosa & Porterfield
Attachment of Cervicoscapular Muscles
• Trapezius - Levator Scapulae
Movements of the Upper Extremities - Cervical
motion induced by shoulder motion
 Shoulder flexion of the upper extremity
can impose excessive motion of
cervical vertebrae
Takasaki H Spine 2009
 Upward rotation of scapula stretches
levator scapulae muscle and cause
rotation of a more flexible cervical
vertebrae.
 Contraction of upper trapezius can
cause rotation of a more flexible
cervical vertebrae – [next slide]

Cervical rotation to the right during left shoulder flexion
Upper trapezius rotates head & neck to opposite side
Right shoulder flexion – no
detectable movement of the
cervical spine
Left shoulder flexion –
detectable movement of the
cervical spinous process to the
left
• Indicative of excessive
mobility of cervical vertebrae
Kendall 1993
Upper trapezius attachments to ligamentum nuchae

Lower Cervical Range of Motion
Orientation of Facet Joints
• upper cervical
– horizontal motion
• lower cervical
– superior motion
Porterfield & DeRosa
Vertebral Motion During Flexionextension
• Flexion - anterior translation 1.9 mm
• Extension - posterior translation 1.6 mm
– retrolisthesis (narrows canal)
Porterfield & DeRosa
Cervical Motion Restricted by Shoulder
Girdle Muscles
• Restricted rotation range of motion
• Passive elevation of shoulder girdle increases
the rotation range of motion
copyright S Sahrmann & Associates
Activities That Contribute
• Holding telephone with shoulder
• Sitting with head turned watching TV
• Sleeping prone with arm overhead and head
turned to opposite side
• Sleeping on couch with head resting on arm
rest
• Falling asleep sitting up
• Bifocals and computer screen
Cervical rotation limited by
trapezius and levator scapulae muscles
Maximum rotation
Shoulders passively elevated

Cervical rotation limited by
upper trapezius & levator scapulae muscles
Maximum rotation
Rotation with shoulders elevated
Cervical Extension Syndrome
• Pain with extension
• alignment: cervical
lordosis
• forward head with
DDD
• muscle changes
– short extensors
– long flexors
Forward Head and Forward Shoulder
Initial rotation
Cervical extension elicited
by stretch of levator scapulae
Neck pain decreased by supporting shoulders &
decreasing cervical lordosis

Post examination

Contributing factors: long trunk, short arms,
large breasts with bras straps adding to downward
pull of trapezius and levator scapulae muscles
Neck pain

History
• 48 Year old female, Neonatal nurse
• Onset 25 years ago
• Severity: 5 – 10/10; 1½ years ago in bed for 1
month; headache 4x/week, 3 awful
• All forms of treatment; lots of drugs
• Observations:
– Laxity; very forward head, thoracic kyphosis,
swayed upper back; exaggerated by body
language;
•
•
•
•
•
Physical Examination
Markedly forward head
Thoracic kyphosis
Swayed upper back
Body language that exaggerated the above
Passive elevation of shoulder
– Decreased the pain in her upper trapezius area
– Increased cervical rotation ROM
Physical Exam
• Standing: post quadruped rocking: alignment
improved
• Standing: facing wall: shoulder flexion with
scapular posterior tilt at completion of flexion
• Standing: back to wall: shoulder flexion:
Physical Exam
• Swayback posture: postural related activity in
abdominal muscles
• Swelling in area of insertion of scaleni
• Forward bending: increased thoracic kyphosis
• Shoulder flexion: 180 deg but decreased posterior tilt
of scapulae
• Supine: neck flexors 4/5, shoulder flexion WNL,
limited chest expansion with deep breath
• Pectoralis minor: stiff L>R
• Shoulder medial rotation: scapular anterior tilt
Diagnoses
• Cervical rotation-flexion with compression
– From scaleni (abdominals)
– From upper trapezius, levator scapulae
• Scapular depression
– Take deep breath to expand rib cage

Progress
• Returned two weeks later, markedly improved
• Posture was notably improved and had
stopped body language habits
• Only 1 severe headache and she knew she
triggered it by lifting heavy object
• Supporting arms stops development of any
early symptoms as does performing exercises.

Treatment Program
• Stop body language
• Correct alignment: stop sway back
– Decrease abdominal muscle activity
• Improve neck flexor strength
• Improve extensibility of scapular depressors
and abdominal muscles and structures
affecting rib cage
• Decrease thoracic kyphosis
Treatment Program
• Quadruped Rocking with relaxation of thoracic spine;
correct support of head and neck
• Standing facing wall; shoulder flexion with shrug
when shoulders are flexed 90 deg
– Scapular posterior tilt at end of range
• Standing back to wall; shoulder flexion, take deep
breath at completion of flexion
• Support arms when sitting; practice cervical rotation
