Neck pain

Background

• Two types:
  • 1. Musculoskeletal
  • 2. Radiculopathy/myelopathy

Clinical Features

• Musculoskeletal
  • Pain is deep, dull ache, episodic
  • History of excessive or unaccustomed activity
  • Pain is localized and asymmetric
  • Referred pain: head (upper cervical segments), limb girdle (lower cervical segments)
  • Symptoms aggravated by neck movement, relieved by rest
• Radiculopathy
  • Pain is sharp or burning
  • Radiates to trapzezial and periscapular areas or down arm
  • Numbness/weakness in myotomal distribution
  • HA may occur if upper cervical roots are involved
  • Symptoms aggravated by neck hyperextension (esp when head is toward affected extremity)
  • Gradual onset of shocklike sensations spreading down spine to extremities
  • Most common at level of 5th cervical vertebra (shoulder abduction, external rotation)

Diagnosis

• Musculoskeletal pain
  • Pain occurs on side away from head movement
• Radiculopathy
  • Spurling test
    • Apply gentle pressure to pt's head during extension and lateral rotation
    • May reproduce pt's radicular pain w/ radiation into ipsilateral upper extremity
  • Abduction relief sign
    • Placing hand of affected extremity on top of head leads to relief
    • Indicates soft disk protrusion
