Injury Analysis
The science of linking crash forces to occupant injuries. Soft tissue injury probability, cervical spine biomechanics, AIS scoring, MIST claims, airbag and seatbelt interaction, and the defensible way to evaluate whether a claimed injury is consistent with the crash.
A crash produces forces. The human body responds to those forces according to published biomechanical thresholds. Injury analysis is the discipline that connects the two. When it's done well, an adjuster knows whether a $75,000 soft-tissue demand matches a 7 mph rear-end, a defense attorney knows when to challenge causation, and a plaintiff attorney knows which injuries are defensible and which ones will get torn apart on cross-examination.
Most claims files don't get this analysis. They get medical records, a demand letter, and a narrative. The medical records describe the injury. The narrative describes the crash. Nothing connects the two except the plaintiff's say-so and the adjuster's experience. This is how claim severity gets mispriced in both directions — inflated soft-tissue demands on minor crashes, and serious injury claims discounted because the damage photos looked unimpressive.
The articles in this category cover how injury causation actually works. We explain the Abbreviated Injury Scale (AIS) and why insurers and attorneys should know it. We walk through cervical whiplash mechanics, lumbar disc biomechanics, rotator cuff mechanics in side-impact crashes, and airbag-induced injuries. We explain MIST cases (Minor Impact Soft Tissue) and the biomechanical thresholds that defense counsel routinely cite against them. And we publish the original research adjacent to the writing, because unsupported claims don't survive deposition.

Seatbelt Pretensioner Injury Causation Proof: 50ms Forces Behind $800K Rib Fractures
A 52-year-old restrained driver walks away from a 28 mph frontal collision with four rib fractures and a sternum contusion. The defense says it was degenerative. The pretensioner deployment data says otherwise. Here's how to prove it.
T-Bone Accident Side Impact Injury Causation Proof
A 42-year-old driver gets T-boned at 32 mph through a driver-side door. The ER documents a splenic laceration and three fractured ribs. Here's how crash physics builds the causation bridge between the impact and the injury, and why that bridge matters more in side impacts than any other collision type.
Life Care Planner Crash Injury Assessment: Future Cost Analysis
A life care planner just received a referral for a 34-year-old rear-seat passenger with an AIS 4 cervical cord injury from a 42 mph side-impact collision. The plaintiff's attorney wants a lifetime cost projection by next month. Here's how crash reconstruction data changes everything about that number.
Biomechanics Expert Witness: When to Hire One and What They Do
A biomechanics expert witness can make or break an injury case, but most attorneys and adjusters don't bring one in until it's too late. Here's what they actually do, when you need one, and how AI-driven analysis is changing the economics of biomechanical testimony.
Low Impact Collision Defense Strategy: Building MIST Cases with Delta-V
A strong low impact collision defense strategy starts with physics, not opinion. Here's how Delta-V data, crash pulse analysis, and biomechanical modeling give claims professionals and defense attorneys the evidence they need to evaluate MIST claims objectively.
Car Accident Injury Documentation for Claims
Proper car accident injury documentation for claims requires more than medical records. Here's how to connect crash physics to claimed injuries using biomechanical analysis, and why that connection makes or breaks claim outcomes.
Low Speed Car Crashes: Minor Damage Doesn't Mean Minor Injuries
A low speed car crash with barely a dent can still produce serious injuries. Here's the biomechanics behind why, and how claims professionals and attorneys get the analysis wrong when they equate cosmetic damage with occupant risk.
G-Forces in Car Accidents: Proving Soft Tissue Injury Claims
Soft tissue injuries are the most disputed claims in auto insurance, but g-force data tells the story that MRIs can't. Here's how crash physics provides objective, courtroom-ready proof of what an occupant's body actually experienced.
Frequently asked
What is the AIS scale and why do claims professionals care?
The Abbreviated Injury Scale ranks injuries from 1 (minor) to 6 (unsurvivable). It's the currency biomechanical engineers use to describe injury severity objectively. For claims professionals, an AIS score gives a defensible, non-medical anchor for severity discussion. An AIS 1 cervical strain does not produce lifetime treatment needs, and having that language in the file changes the negotiation.
Can crash photos really tell you if someone was injured?
Photos don't diagnose injury. What they do is establish the crash forces the occupant experienced, and from those forces you can calculate injury probability by body region using published biomechanical thresholds. It's not a medical opinion. It's a physics-based likelihood anchor that informs how plausible a claimed injury is given the crash.
What is a MIST case and why are they controversial?
MIST stands for Minor Impact Soft Tissue. It refers to low-speed crashes (typically Delta-V under 8-10 mph) with soft-tissue demands above what the crash physics predicts. They're controversial because the science says mild crashes rarely produce lasting injury, but the medical record says they did. Injury analysis is how the two sides reconcile the dispute.
