Well, this is one of the great questions, for which everybody would like an answer.  I’ve written about a number of things in this space, but unfortunately, the source of everyone’s back pain will not be one of them.  What I would like to impart to readers is a very common risk factor for low back injuries.

I’d suggest sitting down before you read on, but that would just add to your risk… that’s right, sitting for long periods of time is a risk factor for low back pain and injury.

New Study on Fatigued Muscles

A recent study undertaken at the State University of New York at Buffalo determined that “the degraded force generating capacity of the fatigued muscles can be a significant risk factor for low back pain^[1].  The research showed that prolonged sitting causes creep (changing length) in muscles primarily responsible for posture and maintaining stability in the spine.  When the same muscles were recruited for lifting or carrying following sitting, they generated less force.  In other words, muscles that have stretched from prolonged sitting are weaker, less able to stabilize and move the spine, and more prone to injury.

Examples of how this phenomenon affects us include:

• taking packages out of the trunk of the car after a long drive,
• getting the newspaper off the ground after sleeping side lying,
• transporting luggage following an airline flight,
• or bending to lift anything at work after awhile at the desk.

The key in all of these situations is that the back muscles are experiencing an increased demanded for force at a time when the muscle is least capable.  This is when injury can easily occur in these back muscles.

Simple Recommendations to Avoid Back Pain

For similar reasons, I frequently recommend that patients avoid twisting the torso while bending and lifting.  These actions put considerable strain on spinal muscles, because tissues are being asked to stabilize and move the spine simultaneously, increasing the risk of overloading the muscles.  Sitting for a long period before doing the same work only increases the risk of injury further.  So remember to take frequent breaks from prolonged sitting and give your muscles time to adjust when asking your back to do work following sitting.

The risks of warming the couch maybe even greater yet.  A newly published article described how prolonged sitting, even when adults participate in physical activity, is a factor for reduced lifespan^[2].  I will examine this topic in a later post.

Proactive vs Reactionary Care

There seems to be two main groups of patients in my office. The first group always has an appointment scheduled and comes into the office for spinal adjustments on a regular basis, while the other population presents for care when they are in crisis.  These two groups illustrate two different models for healthcare.  The regularly scheduled patients are proactive and present for care to maintain their well-being.  Patients who present only when they are in pain represent care which is reactionary – this is how most Americans utilize healthcare.  Reactionary or crisis care means needing a root canal when flossing, brushing and regular cleanings would have preserved healthy teeth and gums; requiring ER services for any number of life-threatening conditions preventable with good diet and exercise; letting our automobile engines seize instead of regularly changing the oil; or visiting the doctor when back pain is too great to bear.

The Eventuality of Back Pain & Arthritis

Estimates indicate that about 80% of people will deal with significant low back pain at some point in their lives.  And a great many of us will eventually experience arthritis pain and stiffness.  Just witness the huge proliferation in products to treat joint discomfort, low back and arthritis pain as a testament to this expanding problem.  From the New England Journal of Medicine, a review found that a clear diagnosis could not be made in near 85% of low back injury cases^[1].  After careful examination, abnormalities could not be found.  Another study, with emphasis on imaging, determined that 97% of low back pain was mechanical in nature^[2].  Maybe degeneration is not pathological, but normal…

Pain, injuries and accelerated degeneration are the result of biomechanical stress.  Indeed, Wolff’s Law tells us that any bone, subjected to prolonged biomechanical stress will adapt to that stress^[3].  This is the same process that causes premature degenerative changes, osteoarthritis, and loss of joint motion.

How Do We Combat These Changes?

With treatments to resolve structural imbalances and support proper biomechanics.  Chiropractic maintenance care is effective because it allows patients to preserve good spinal biomechanics and smooth, pain-free joint mobility.

We know how to abide by a more sensible, preventative model.  We follow a similar paradigm in the maintenance of our teeth and automobiles.  Unfortunately, our spines are not something that can be replaced.  Start the new year off right and resolve to keep your spine happy and healthy for years to come.

Staying Well is Staying in Flow

Chiropractic is an alternative health discipline which aims to remove interruptions to the flow of normal nerve transmission. The spinal cord is the main pathway for nerve messages to and from the brain. These signals allow our brain to perceive sensations, control our heart, lungs, and other organs and allow us to direct movements of our body. The nerve branches, which bring signals to all parts of the body, exit the spinal cord through holes on either side of the vertebral column. Each of the 26 bones of the vertebral column are separated by discs, which form joints with the vertebrae above and below. These joints are what connect the spine and give it flexibility. The vertebral column also surrounds and protects the spinal cord.

Inhibiting Your Wellness

Should a vertebra move out of alignment, say from trauma, emotional stress or another cause, it is likely that the nerve signals will be compromised. The chiropractic profession believes that this compromise negatively impacts the ability of nerves to carry messages and therefore a person’s health. Likewise, emotional stress, muscle tension, and poor ergonomics can stress the body/spine and also reduce the transmission of normal nerve messages. Chiropractic medicine is based on the belief that the body has an innate ability to heal itself. Chiropractors work to remove impediments to spinal motion and normal nerve transmission to aid the body in self-healing. Chiropractors primarily use adjustments to improve spinal motion. In this way, patients can be relieved of back, neck or joint pain, and headaches without drugs or surgery.

Recognizing Your Health through Chiropractic Care

National Chiropractic Month is a consolidation of two previous observances: Correct Posture Month and Spinal Health Month. Since good posture and proper ergonomics helps to eliminate stress on the body and spine, training to improve and maintain good posture is one of the things I usually stress during treatment. Considering how integral posture and spinal health are to chiropractic, it is very fitting that these endeavors be recognized this month. Poor ergonomics and lack of joint motion today could be the cause of your back pain or headache tomorrow… Call to make an appointment and have your spine checked today!
