Cervical acceleration-deceleration (CAD) injuries, commonly known as whiplash, occur when the neck is forcefully whipped backward and forward during a vehicular collision. Even low-speed rear-end impacts can generate enough rotational torque to stretch cervical ligaments, herniate cervical discs, and strain paraspinal musculature.
Stages of Whiplash Recovery & Chronic Symptoms
While minor soft-tissue strains may improve within six to twelve weeks with conservative chiropractic care and physical therapy, a significant percentage of accident victims experience chronic whiplash syndrome lasting months or years:
- Acute Phase (Weeks 1 to 4): Severe neck stiffness, reduced range of motion, cervicogenic headaches, and muscle spasms.
- Subacute Phase (Weeks 4 to 12): Radiating pain into shoulders, upper back, or arms (cervical radiculopathy), numbness, and tingling.
- Chronic Phase (Month 3+): Persistent myofascial pain, sleep disruption, cognitive fatigue, and chronic migraines requiring specialized pain management.
Documenting Your Whiplash Injury for Insurance Claims
Insurance adjusters frequently dismiss whiplash as a “minor soft-tissue issue.” Overcoming this tactic requires objective medical documentation, including MRI imaging to detect facet joint damage or disc bulges, detailed physical therapy progress notes, and clear medical narratives from treating physicians linking the injury directly to the collision.
