Whiplash Injury: Neck Pain, Stiffness, Headaches, and Treatment from Mild to Severe Cases

Whiplash-associated disorder (WAD) results from acceleration-deceleration forces (typically rear-end collision) causing rapid neck flexion-extension.

Symptoms (WAD Grades)

• Grade 0: No complaints, no signs.
• Grade I: Neck pain, stiffness, tenderness only.
• Grade II: Neck complaints + musculoskeletal signs (decreased ROM, point tenderness).
• Grade III: Neck complaints + neurological signs (decreased reflexes, weakness, sensory deficits).
• Grade IV: Fracture/dislocation.

Common Manifestations

• Neck pain, reduced range of motion
• Cervicogenic headache (occipital, frontal)
• Dizziness, tinnitus, visual disturbances
• Shoulder/arm pain, paresthesias
• Cognitive difficulties (concentration, memory)
• Psychological distress (PTSD, anxiety, depression)

Treatment

• Acute: Early mobilization (not collar immobilization), NSAIDs, heat/ice, education.
• Subacute: Physical therapy (strengthening, proprioception, posture), manual therapy.
• Chronic (>3 months): Multidisciplinary: CBT, graded exercise, pain management, possible referral for interventional procedures.
• Red Flags: Neurologic deficit, structural instability, myelopathy → urgent imaging/surgical consult.

Most recover within weeks to months; ~30–50% develop chronic symptoms. Early active management improves prognosis.
