“Dear Dr. Doperak, as I watched my son leave our home this morning it was clear his posture wasn’t normal. I’m concerned. Should I be concerned or is this okay?”


Dr. Doperak: “Great question! Yes, you should be concerned; as a twig is bent, so grows the tree.

Posture is the window to the spine and a growing spine is subject to a particular law that dictates how bones grow due to stress. This law, known as Heuter-Volkmanns, states compressive stress slows bone growth whereas a lack of stress accelerates growth. So, to answer your question, the weight of your sons backpack is creating specific compressive stresses causing his body to compensate to maintain balance; this is why his posture is distorted and why you should be concerned.

Let’s continue working through this scenario. For example, if your son carries his backpack on the right side of his body, the compressive stress on the right would slow bone growth. This is not okay. Also, because the weight on the right side would cause him to fall to the right, you’d expect to see his body shift to the left across midline for balance; this could result in a left high shoulder, a left thoracic spine translation, or worse yet, a scoliosis.

Let’s talk about a potential solution. The BETTER scenario is to have the weight of his backpack evenly distributed between the left and right side but also between the front and back. Another consideration is that a heavy backpack placed over his back/spine will cause him to lean forward whereas the same heavy backpack placed in front of his body will cause him to lean back. Both scenarios created center of gravity issues over time and will also influence the way his bones grow negatively.

Now, let’s talk about the best case scenario. In my opinion, the BEST scenario is to equally distribute the contents of his backpack into two separate bags allowing him to carry one bag in his left hand and one in his right. Now, with the weight equally distributed between the left and right, as long as he walks upright maintaining good posture and positioning between the front and back, his daily activity will be beneficial and strengthening instead of detrimental.

Not sure this is worth the effort? The authors of a 2012 study referenced below conclude, ‘backpacks increase the risk of back pain and the possibly of back pathology. The prevalence of school children carrying heavy backpacks is extremely high. Preventive and educational activities should be implemented in this age group.’ So, a simple backpack that causes postural distortions can certainly have serious consequences to a growing spine. Help ensure your son’s growing spine has a fighting chance. Some minor adjustment can go a long way to a healthy spine for a lifetime. This is Dr. Doperak, signing off.”

The Big Idea

A slip on the snowy sidewalk in winter is a small thing.  It happens to millions. A fall from a ladder in the summer is a small thing.  It also happens to millions. The slip or fall produces a subluxation.  The subluxation is a small thing. The subluxation produces pressure on a nerve.  That pressure is a small thing. That decreased flowing produces a dis-eased body and brain.  That is a big thing to that man (woman/child). Multiply that sick man (woman/child) by a thousand, and you control the physical and mental welfare of a city. Multiply that man (woman/child) by one hundred thirty million, and you forecast and can prophesy the physical and mental status of a nation. So the slip or fall, the subluxation, pressure, flow of mental images and dis-ease are big enough to control the thoughts and actions of a nation. Now comes a man (woman). And one man (woman) is a small thing. This man (woman) gives an adjustment.  The adjustment is a small thing. The adjustment replaces the subluxation.  That is a small thing. The adjusted subluxation releases pressure upon nerves.  That is a small thing. The released pressure restores health to a man (woman/child).  This is a big thing to that man (woman or child). Multiply that well man (woman/child) by a thousand, and you step up the physical and mental welfare of a city. Multiply that well man (woman or child) by a million, and you increase the efficiency of a state. Multiply that well man (woman/child) by a hundred thirty million, and you have produced a healthy, wealthy, and better race for posterity. So, the adjustment of the subluxation to release pressure upon nerves, to restore mental impulse flow, to restore health, is big enough to rebuild the thoughts and actions of the world. The idea that knows the cause, that can correct the cause of dis-ease, is one of the biggest ideas known.  Without it, nations fall; with it, nations rise. This idea is the biggest I know of.

“Health is the result of healthy living.  Health, or a lack thereof, is a progression taking place over time. Whether you grow stronger or slowly degenerate is largely determined by your everyday activities. Chiropractic care provides the positive stimulus your body requires to build healthy tissue and grow stronger. Make a bold and educated decision.  Start fighting against the negative effects of time, aging and gravity today!”
