Physical Therapy Expert Witness for Rehabilitation, Function, and Standard of Care Review
Expert witness services for litigation involving motor vehicle accidents, falls, concussion, traumatic brain injury, neurologic injury, orthopedic injury, and rehabilitation-related disputes.
Why a Physical Therapist Matters in Litigation
Physical therapists are the premier healthcare professionals for evaluating movement, functional capacity, and standard of rehabilitation care. In litigation, a Physical Therapy (PT) expert witness provides a unique and vital perspective that bridges the gap between medical diagnoses and real-world functional impact. While a physician may diagnose an injury, a physical therapist explains exactly how that injury restricts a person’s ability to work, perform daily activities, and maintain their quality of life.
Whether examining the standard of care in a clinical setting or analyzing the long-term functional loss following a traumatic event, my role as an expert witness is to provide objective, evidence-based analysis that translates complex clinical data into clear, actionable insights for legal professionals.
Case Types Where a PT Expert Witness Adds Value
Motor Vehicle Accidents
Analysis of whiplash, soft tissue damage, and long-term functional loss following collisions.
Falls & Balance
Evaluation of premises liability, gait instability, and age-related functional impairment.
Concussion & mTBI
Expert witness for traumatic brain injuries, vestibular dysfunction, and return-to-activity.
Standard of Care
Review of rehabilitation protocols, medical necessity, and clinical practice adherence.
Orthopedic Injury
Functional analysis of complex neck, back, and joint injuries requiring long-term care.
Neurologic Injury
Insight into recovery potential and functional decline for strokes and neurologic disorders.
Utilization Review
Verification of treatment frequency, duration, and billing compliance in therapy claims.
Future Care Projections
Estimation of ongoing rehabilitation costs and future functional requirements.
Motor Vehicle Accidents and Functional Loss
Motor vehicle accidents often result in complex multi-system injuries that directly impact a person's ability to perform activities of daily living. A physical therapy expert witness provides a critical link between medical diagnoses and real-world functional impairment.
- Standard of care in managing whiplash-associated disorders (WAD).
- Biomechanical analysis of movement patterns following orthopedic trauma.
- Objective measurement of functional loss and endurance deficits.
- Impact of soft tissue and neurologic injury on occupational and domestic duties.
By translating clinical documentation into objective functional terms, Dr. Mortensen helps counsel and jurors understand the magnitude of physical limitation resulting from an collision, ensuring that standard of care and medical necessity are accurately evaluated.
Falls, Balance, and Functional Impairment
A physical therapist is uniquely qualified to assess the interplay between a patient’s physical impairments and their environment. When a fall occurs, the central question is often whether it was an unpreventable accident or the result of a failure to address a known functional risk. My analysis provides clarity on balance metrics, gait mechanics, and the adequacy of safety interventions.
- Standard of care for fall risk assessments and prevention protocols.
- Clinical significance of balance testing scores (e.g., Berg Balance Scale, TUG test).
- Impact of neurologic or orthopedic deficits on postural stability.
- Analysis of gait deviations and use of assistive devices.
- Relationship between vestibular dysfunction and fall events.
Concussion and mTBI Cases
Mild traumatic brain injury (mTBI) and concussion cases often turn on functional evidence and the objective presentation of symptoms. As a vestibular and neurologic rehabilitation specialist, Dr. Mortensen provides expert analysis of whether the persistent functional deficits reported by a patient are consistent with established pathophysiological mechanisms of concussive injury.
Functional analysis includes the evaluation of balance, gaze stability, and motion sensitivity, providing legal teams with the objective data required to support or refute claims of permanent impairment. Analysis points include:
- Standard of care for post-concussion and vestibular rehabilitation
- Medical necessity of long-term neurologic physical therapy
- Objective measurement of balance and visual-vestibular dysfunction
- Analysis of return-to-activity and return-to-work readiness protocols
- Differentiating pre-existing balance disorders from injury-related mTBI symptoms
Functional Analysis and Movement Assessment
Physical therapy expertise is essential for translating medical diagnoses into the realities of daily life. While a surgeon may focus on the integrity of a joint or a neurologist on imaging findings, the physical therapist evaluates how these conditions manifest in movement, balance, and the ability to perform life tasks.
Technical Assessment Metrics
- Gait and postural stability analysis
- Dynamic balance and fall risk metrics
- Range of motion and musculoskeletal integrity
- Functional strength and lifting capacity
- Neuromuscular control and movement quality
- Standardized objective outcome measures
Dr. Mortensen provides objective, evidence-based analysis of functional impairment, determining how injuries impact a plaintiff’s vocational capacity, community mobility, and quality of life.
