Whiplash Injury Myth #2: No Damage = No Injury

Chiropractic treatment of whiplash injury
You can suffer a whiplash injury even when there is little damage to your vehicle.

If you read my last article, Whiplash Injury Myth #1, you’ll know that relaxing during a car crash is just about the worst thing you can do.  Now hopefully you’ll never be involved in a crash, but for the sake of argument let’s say that you are.  You’re sitting a red light minding your own business, and all of a sudden BAM!  Your head and neck snap back as you’re struck from behind by another vehicle.

You get out of your car to survey the Damage, but all you find is a little scratch on your bumper.  You breath a sigh of relief and realize how lucky you are, but two or three days later your neck starts to hurt… a LOT.  And people are looking at you funny.  There’s no way that little ding on your bumper could have caused a whiplash injury… is there??

No Damage = No Whiplash?  No Way!

At Eastside Chiropractic Group, we’re fans of information.  In my practice, I want to make sure people are well informed, so they can do what’s best for their health.  With car crashes, that can mean overcoming some deep-seated ideas. For instance, there is this long-held belief that if you are involved in a car crash and your vehicle sustains little damage, there is no way you could suffer a whiplash injury.  But this just isn’t true.  In fact, a lack of damage can make things worse.  When your car is struck by another, the striking car transfers energy to your vehicle.  If your bumper crumples it can absorb some of that energy.  If your bumper remains rigid (undamaged), that energy may be transferred to you instead.

Watch the video below.  It is courtesy of the Spine Research Institute of San Diego, where they have been studying these types of crashes for many years.  I recommend you watch it a few times and take note of how quickly the whole thing happens.  Watch how quickly and forcefully the driver’s head whips back and forth, and how he appears dazed for a few seconds after the collision.


After watching this video, it’s fairly obvious that this poor guy’s head and neck absorb quite a jolt.  So what speed did the striking car hit his vehicle at?  What’s your best guess?  You might be surprised. Take a look at this next video to see this collision in full view.


One thing to note in the video above, there is no noticeable damage to either vehicle.  That’s because the crash occurred at only 7.8 mph!  So how can such a slow collision cause such significant forces?

Whiplash Can Occur At Low Speeds

During a rear end collision, the vehicle being struck accelerates Forward.  If your bumper crumples, it absorbs some of the potentially damaging force of the collision.  If it remains intact, your car (and body) shoot forward more quickly, increasing the strain on your neck.  The more quickly your body accelerates forward, the more forcefully your neck and head whip backward.  Eventually your head has to catch up to the rest of your body (or leave it behind), which causes your neck to whip forward again.  All told, this takes place in just a fraction of a second.

Here is the same crash in super slow motion.  The first car strikes the second from behind, causing it to accelerate forward.  As the driver’s body is pulled forward by his seat, his neck bends back forcefully, and then whips forward again as it catches up to his body.  The numbers in this video also tell a story.  The first vehicle is traveling at 7.8 mph when contact is made.  The struck vehicle springs forward at 5.8 mph as a result.  And this generates 12.7 g of head acceleration.  That’s insane!!


Here’s a question to consider.  Why do people look for broken eggs, even when there’s no visible damage to the carton?  It’s because the contents are more fragile than the container.  The same can be said for cars and occupants.  Sometimes people get hurt in car crashes that leave their vehicles virtually unharmed.

Don’t let a lack of damage to your vehicle make you downplay an injury.  If you’ve had a car crash, get checked out.  Whiplash treatment is more effective early on, before your injuries become chronic, and that means less time spent in pain.
