Can poor posture

predict mortality?

Maybe so according to a recent study and that ain’t all! Turns out that posture (in this case thoracic HYPER kyphosis) is getting some attention in the literature and appears related to a wide range of ailments, of which increased risk of death is only one. Only problem is that chiropractors aren’t doing the research. OH NOOO!!!

Because while half of our profession has relegated spinal structure to the dustbin of chiropractic history in pursuit of more “sophisticated” theories, our MD and PT colleagues are more than happy to lay the scientific ground work relating spinal structure to a wide range of ailments. End Of Rant…promise.

First off…thanks to Dr. Roger Coleman at ScienceInBrief.com for making me aware of this research. For those of you who aren’t familiar with the ScienceInBrief.com
project, we review scientific articles on a wide range of subject which are of interest to chiropractors. Unlike this newsletter, very little of what we do at SIB is directly related to posture based chiropractic. But occasionally, I run across articles which are relevant for readers here at Postural Rehab. Here’s a recap of the article along with some thoughts on managing thoracic HYPERkyphosis.

Hyperkyphotic Posture Predicts Mortality in Older

Community-Dwelling Men and Women: a prospective study 1

The Facts:

a. The authors studied the association between thoracic hyperkyphosis and mortality in over 1300 individuals with a mean age of 73.

b. If the individual laid on their back and was unable to rest the head on the table without putting the neck into hyperextension they were considered to have thoracic hyperkyphosis.

c. Patients were followed for an average of 4.2 years.

d. Those “with hyperkyphotic posture had greater mortality rates. Increased severity of “kyphotic posture” appeared to be associated with a higher risk of mortality.

Discussion: Obviously, the inability to bring the head back to neutral resting position COULD be also caused by factors other than thoracic hyperkyphosis, but what’s important here is that POSTURE appears to be associated with early mortality. Interestingly, thoracic kyphosis was found to be twice as common in men (44%) as women(22%) in this study, which seems to be at odds with conventional thought that thoracic hyperkyphosis is commonly caused by osteoporosis, a condition much more common in women.

The “NORMAL” Thoracic Kyphosis

Obviously, a radiographic evaluation of the T spine gives us a much more accurate idea of the sagittal curvature.

Harrison defined the thoracic kyphosis as ELLIPTICAL in shape, having a Jackson’s (Cobb) angle of 44.2 degrees from T1-T-12. Realizing the difficulty of visualizing both T1 and T12 on the radiograph, Harrison recalculated the model to reflect a thoracic kyphosis of 33.3 degrees between T 3 and T10. 2

Vaz et al, define the average thoracic kyphosis as 47 degrees in healthy young adults. 3

Boseker et al, defined a range of “normalcy” between 20-50 degrees in healthy children. 4

So you can see that opinions vary as to what is actually normal. I encourage interested readers to come to do some reading and establish in their mind what they consider to be the appropriate upper limits of thoracic kyphosis. Personally, I generally tend to view curves in excess of 40 degrees (as measured from T3-T10) as suspect. That’s just my opinion based on my reading of the literature, but 40 degrees is an upper limit you will find frequently cited. Regardless of which value you consider appropriate, it is important to have some sort of firm upper limit, above which you will start considering clinical intervention.

Clinical Management:

A number of tools have been looked at for treating thoracic hyperkyphosis but definitive research is still sorely lacking. Some options you may want to consider are exercise, bracing, and spinal remodeling. Here are two simple, inexpensive tools I have found to be helpful.



Thoracic Rolls

One method of actively addressing the thoracic kyphosis is to simply place the patient over a large foam roll ( our Multipurpose Rolls in the 10-13″ range work well for this), have them raise their hips up, and then “roll” themselves up and down over the roll by alternately flexing and extending the knees. This does two things. First, it introduces a fulcrum effect into the mid T spine to help reduce the kyphosis. Secondly the rolling motion helps mobilize the spine and costovertebral articulations to promote a reduction of kyphosis.

Thoracic Arch

Another method is to simply allow the patient to passively rest over a foam roll or fulcrum for 20-30 minutes. This time frame allows for stretching of the paraspinal tissues to occur and for the spine to “remodel” into a reduced kyphosis. I use our Thoracic Archfor this purpose and we now have lots of doctors using these arches on a regular basis to remodel the T spine.

I generally start with the patient over the arch with the fulcrum at the apex of the kyphosis as shown above. Once they can comfortably relax for the full 20-30 minutes without any problems or soreness, I place a 1″ spacer beneath the arch to raise it up and increase the leverage effect into the mid thoracics. Occasionally, I may end up placing an additional spacer or two as needed to effectively introduce extension into the thoracics.

On-the-Job Back Pain Isn’t Going Away

Lifting boxes, pushing brooms, reaching for files, carrying supplies — is it any wonder that so many people suffer from job-related low back pain? No matter what your occupation, back pain can make your life miserable at any time. Chiropractor ambler, Ambler Chiropractor

But how big is the problem?

To answer that question, researchers analyzed claim data from three major sources: the Washington State Department of Labor and Industries; the Bureau of Labor Statistics; and a national workers’ compensation provider, over a period of 4-9 years. Results indicated that low-back pain claim rates decreased by 34% from 1987-1995, and claim payments declined by 58% over the same time period. But the problem isn’t going away, either. Just look at these numbers:

  • $8.8 billion was spent on low-back pain workers’ compensation claims in 1995.
  • Nearly two out of every 100 privately insured workers filed a low-back pain claim in 1995.
  • Payments for these claims accounted for almost a fourth (23%) of the total workers’ compensation payments in 1995.

So if you think you can avoid low back pain at the workplace, just look at these numbers, and think again. Better yet, help continue the decline in low back pain cases by getting regular adjustments at your ambler chiropractor
