Child Car Seat Safety

Recently the American Academy of Pediatrics changed its position on car seats by increasing the age to two years old that we should keep our children in rear facing seats.  Here is part of their statement on the subject:

A rear-facing child safety seat does a better job of supporting the head, neck and spine of infants and toddlers in a crash, because it distributes the force of the collision over the entire body,” Dr. Durbin said. “For larger children, a forward-facing seat with a harness is safer than a booster, and a belt-positioning booster seat provides better protection than a seat belt alone until the seat belt fits correctly.”


While I am happy to see an organization in the USA make this recommendation they could have gone further. After reviewing the literature I firmly believe that we should keep our children in rear facing seats as long as possible.  In a number of European countries it is commonplace to keep children in rear facing seats until they are 5 years old or up to 55lbs.  Their standards are based on protecting the fragile neck and spine of children that are in greater risk in a forward facing seat than a rear facing one.  In high speed collisions a child is more likely to suffer spinal injuries or even death in a forward facing seat than in a rear facing seat.  Rear end collisions are not as big of a concern because in high speed rear end crashes the car should absorb most of the impact force and protect its occupants.  Here is a video with animation that shows the difference between the two car seats. 

You can say that this is just an animation and might not depict what would actually happen, but this animation is directly from impact tests done in Europe.  Did you know that in the US side impact testing is not required of child safety seats?  That fact alone shows that the US regulation of car seat safety is lacking far behind its European counterparts.

Most people who have reservations about this usually mention two things; first is that it can not be comfortable for a child to sit cross legged or with their knees in their chest, the second is the child might injure their legs or break a leg in a crash. This first concern might be true for an adult, but a child does not share our in flexibility in the hips so they should be comfortable facing rear especially if that is all they know. You might have a problem transitioning them to a rear facing seat after a year or more of forward facing.  As for injuring or breaking a leg, there is little to no evidence of this occurring in a rear facing seat, but there is numerous evidence for severe neck and spinal injuries in forward facing seats. Even if your child might break a leg in a crash, wouldn't that be better than breaking their neck? 

I bring this up on memorial day weekend, not to scare parents but to help them make informed decisions about their family's health.  European safety standards are far better than ours and it is not a wonder why.  In the US there are too many too powerful special interest groups that have control over regulation.  It was a bold move for the AAP to change their recommendations but it has come long after parts of Europe and does not go far enough.  If anything I hope that this article starts a little fire to get better informed on your child's safety as they travel in your cars. To be honest I wish I could say we kept our kids in rear facing until they were 5 years old but we did not, we did make it to about two years old though with each of them.  Today we have them in booster seats that have backs to them, backless boosters are not safe but that is a topic for another day.

Here are a few other Internet sources to read to help you decide the best actions for your family.

This a a car safety website that has extensive info on rear facing car seats.

This link, and this other one are some blogs that have not been updated in a while but still have good personal information from people who keep their children in rear facing seats.

Chiropractic Manipulation as good as surgery for Sciatica

In reviewing recent research on chiropractic care I came across this paper,Manipulation or microdiskectomy for sciatica? A prospective randomized clinical study., published in the October 2010 Journal of Manipulative and Physiological Therapeutics.  This is a link to just the abstract, but even that is good enough to see what was accomplished with this study. 
The researchers divided 40 participants who had failed nonoperative management including PT, massage, lifestyle modification, and acupuncture for the treatment of sciatica.  Of the 40 some underwent microdiskectomy, which is a minimally invasive surgical procedure that involves removing a portion of the spinal disc that is placing pressure on either the spinal cord or spinal nerve root.  The other participants underwent a course of care involving chiropractic spinal manipulation.
Ultimately both groups showed significant improvement to about the same degree, which shows that chiropractic spinal manipulation or adjustments can be just as effective as surgery for sciatica. 


This study positively shows that in some cases of sciatica chiropractic care can be effective and in the few cases it is not the delay in surgery did not negatively effect outcomes.  When you pair this study with a few other recent ones a picture starts to develop that a trial of chiropractic care for low back pain and sciatica may be the best place to start as opposed to "medical" care.  The "medical" conservative management of low back and sciatica care that includes PT, lifestyle modification, pain medications, and home exercises have shown to not be as effective as chiropractic care in some very recent studies. A recent study on cost found that care for low back pain is less expensive when starting with a chiropractor than when you start in the ER, UC, or family doctor.

Sciatica is not always caused by a bulging disc although a bulging disc may be involved in these cases treating the bulging disc does not always eliminate the pain. What we do is work to stabilize the lower back that eliminates inflammation around the sciatic nerve and that eliminates the pain as well as helps to prevent it from returning.  This has been made easier with our BStrong4Life system, if you have any questions about this give us a  call or email me with them.
