Motor Vehicle Accident Expert Witness for Rehabilitation and Functional Injury Analysis

Expert witness services for litigation involving motor vehicle accidents, whiplash injuries, concussion, mild traumatic brain injury, dizziness, vestibular dysfunction, and long-term functional impairment.

Why Physical Therapists Matter in Motor Vehicle Accident Cases

Physical therapists are often the primary providers for patients recovering from motor vehicle accidents. Because they see patients multiple times per week over several months, PTs possess the most detailed documentation regarding a patient’s functional trajectory, pain levels, and response to treatment. In MVA litigation, this documentation is critical for establishing the mechanism of injury, current functional limitations, and the long-term impact on the patient’s quality of life.

Dr James Mortensen provides expert analysis of these clinical records to bridge the gap between medical documentation and legal strategy, offering objective insight into injury severity and rehabilitation necessity.

Common Injuries in Motor Vehicle Accident Litigation

Successful litigation of motor vehicle accident cases requires a deep understanding of the objective clinical findings associated with common traumatic injuries.

Neurological Injuries
  • Concussion and Mild Traumatic Brain Injury (mTBI)
  • Whiplash-Associated Disorders (WAD)
  • Post-Concussion Syndrome
Sensory & Vestibular
  • Vestibular Dysfunction and Dizziness
  • Benign Paroxysmal Positional Vertigo (BPPV)
  • Balance Impairment and Fall Risk
  • Disc Herniations (Cervical, Thoracic, Lumbar)
  • Facet Joint Injuries
  • Chronic Pain and Functional Decline
Physical & Functional

Functional Limitations Often Seen After Car Accidents

Injuries sustained in motor vehicle accidents frequently result in measurable functional deficits that impact a patient’s ability to return to work, manage a household, or maintain their prior quality of life.

Reduced tolerance for sustained sitting and standing tasks

Impaired cervical and lumbar range of motion affecting driving

Difficulty with lifting, carrying, and overhead reaching

Reduced balance confidence and increased risk of falls

Persistent dizziness and loss of balance (Vestibular dysfunction)

Cognitive processing delays impacting occupational performance

Inability to tolerate screen time or light sensitivity (TPS/mTBI)

Dependency on assistive devices or environmental modifications

Concussion, Whiplash, and Hidden Functional Impairment

Motor vehicle accidents often result in rapid acceleration-deceleration forces that can cause both structural and functional injuries. While fractures and lacerations are readily identified, neurological and soft tissue impairments—such as concussion and whiplash—can be more difficult to quantify without specialized clinical analysis.

Dr. Mortensen provides expert analysis of common manifestations including:

  • Post-concussion syndrome and persistent dizziness
  • Cervicogenic dizziness and vestibular dysfunction
  • Visual tracking impairments and gaze instability
  • Whiplash-Associated Disorders (WAD) and chronic neck pain
  • Functional limitations in daily activities and vocational capacity
