Osteoporosis and Chiropractic:

I see many older (and sometimes younger) patients in my San Diego chiropractic office who have been diagnosed with osteoporosis.  Osteoporosis is an insideous  disease.  Initially it developes without any clear symptoms, affecting the skeletons’ bone density.  Osteoporosis is usually discovered by special testing or bone weakening that leads to fractures which can result in falls, back pain, neck pain, etc.
I am always surprised that those diagnosed with osteoporosis know so little about it.  I did a search on line and found the following article that is worth reading.
Osteoporosis is a disease of bone leading to an increased risk of fracture. In osteoporosis the bone mineral density (BMD) is reduced, bone microarchitecture is disrupted, and the amount and variety of non-collagenous proteins in bone is altered. Osteoporosis is defined by the World Health Organization (WHO) in women as a bone mineral density 2.5 standard deviations below peak bone mass (20-year-old sex-matched healthy person average) as measured by DXA; the term "established osteoporosis" includes the presence of a fragility fracture.[1] Osteoporosis is most common in women after the menopause, when it is called postmenopausal osteoporosis, but may develop in men and premenopausal women in the presence of particular hormonal disorders and other chronic diseases or as a result of smoking and medications, specifically glucocorticoids, when the disease is called steroid- or glucocorticoid-induced osteoporosis (SIOP or GIOP).
Osteoporosis can be prevented with lifestyle advice and medication, and preventing falls in people with known or suspected osteoporosis is an established way to prevent fractures. Osteoporosis can be treated with bisphosphonates and various other medical treatments.
Osteoporosis itself has no specific symptoms; its main consequence is the increased risk of fracture. Osteoporotic fractures are those that occur in situations where healthy people would not normally break a bone; they are therefore regarded as fragility fractures. Typical fragility fractures occur in the vertebral column, hip and wrist.
The symptoms of a vertebral collapse ("compression fracture") are acute back pain, often with radiculopathic pain (shooting pain due to compression of a nerve) and rarely with spinal cord compression or cauda equina syndrome. Multiple vertebral fractures lead to a stooped posture, loss of height, and chronic pain with resultant reduction in mobility.
Fractures of the long bones acutely impair mobility and may require surgery. Hip fracture, in particular, usually requires prompt surgery, as there are serious risks associated with a hip fracture, such as deep vein thrombosis and a pulmonary embolism, and increased mortality.
The increased risk of falling associated with aging leads to fractures of the wrist, spine and hip. The risk of falling, in turn, is increased by impaired eyesight due to any cause (e.g. glaucoma, macular degeneration), balance disorder, movement disorders (e.g. Parkinson's disease), dementia, and sarcopenia (age-related loss of skeletal muscle). Collapse (transient loss of postural tone, with or without loss of consciousness, leads to a significant risk of falls; causes of syncope are manifold but may include cardiac arrhythmias, vasovagal syncope, orthostatic hypotension and seizures. Removal of obstacles and loose carpets in the living environment may substantially reduce falls. Those with previous falls, as well as those with a gait or balance disorder, are most at risk.
Osteoporosis requires special considerations in our office.  Chiropractic techniques involving little or no force have to be utilized to ensure patient safety.  In addition to variations in technique, nutritional suppliments are also encouraged, especially mineral supplimentation.  Osteoporosis treatment requires a multifaceted approach in order to see improvements.  Patients also must show patience with treatment as results are usually only seen with prolonged periods of care.

Doc

Stretching and Chiropractic

The headline of this article could be interpreted in a variety of different ways.  For the purposes of this blog post it will address our physical flexibility.  Flexibility is an important measure of our physical fitness.  Flexibility is just as important to our overall health as is strength, endurance, aerobic capacity and body composition.

One of the big problems that I encounter with my patients in my San Diego Chiropractic office is a lack of flexibility in the joints.  Strong muscles that span flexible joints are ideal for everything from mundane household chores to weekend athletic adventures.  A lack of stretching catches up to us when we perform movements beyond the normal for our lifestyles or activities.  In some cases, an extreme movement can be something as simple as reaching to the table behind you for your cup of coffee.  Neck pain, back pain, arm pain and leg pain can all occur as a result of injuries due to inflexibility.

As a general rule, as our bodies age, our physical fitness degrades.  Regarding flexibility, we tend to loose it.  That is why it is very important to develop flexibility when we are younger and maintain it as we get older.  Even those of us in our forties or older must try to regain some and maintain most of our flexibility even though we are not 20 something anymore.

I always tell people to think about how much strength, endurance or in this case flexibility that they have lost in the last 10 or 20 years.  I know that I am not as physically fit as I was when I was 20 or even 30 years old.  There is no way that I want that same trend to continue over the next 20 years.  In order to prevent the atrophy of our bodies we have to maintain them through stretching and exercise.

In addition to perhaps regaining the ability to touch your toes, becoming more flexible will also help in the following ways.

1)    Helps Relieve Stress:  Flexible muscles are loose and relaxed muscles.  Loose, flexible muscles are less likely to tighten up during stressful, tense situations.
2)    Helps Improve Posture:  Loose muscles help your body maintain better posture.  Avoiding unnecessary postural stress will help you feel better.
3)    Helps Increase Circulation:  Increased circulation comes as a result of consistent stretching.  Improved circulation helps bring nourishment to your muscles while removing toxic build-up of lactic acid and other waste products.
4)    Helps Improve Coordination:  Stretching will improve your joints range of motion providing for better balance, mobility and coordination.  Improved coordination will help us with all athletic activities and help prevent falls as we age.

I always recommend stretching in the form of Yoga.  Stores like Target have many instructional DVDs on Yoga.  Linda and I have always found that Rodney Yee produces better than average DVD courses on Yoga.  If you are not experienced in Yoga you will need to start with a beginners course, many people look at Yoga and assume that it is easy.  THIS IS NOT THE CASE.  Yoga is not only a great stretch but an excellent work out and you can hurt yourself if you over-do it.

Some guidelines for safe stretching include:
1)    Warm up Before You Begin
2)    Don’t Bounce While Stretching
3)    Avoid Pain While Stretching – It Should Feel Like A Good Stretch – Not A Painful One
4)    Stretch Both Sides
5)    Stretch Both Before and After Exercise

Computer Ergonomics, Work Postures and Injury

Computer Ergonomics, Work Postures and Injury
My chiropractic clinic is located in San Diego, California.  For whatever reason, we see many patients suffering from neck pain, back pain, shoulder pain, wrist pain and hand pain as a result of computer work.  As we spend increasing amounts of time at our computer workstations, we need to be aware of how the design and arrangement of our equipment can impact our chances of injury.   Computer ergonomics is the study and / or implementation of work station design with the purpose of reducing or eliminating physical stress.
My interest in repetitive stress syndromes began approximately 10 years ago when my practice started seeing a much greater number of people suffering from the effects of computer / keyboard work.  Despite all of my training and continuing education related to these types of injuries, I quickly realized that traditional treatment for this type of injury was marginally successful at best.
Any type of therapy was going to have to include the application of basic ergonomic principals to the patient’s work environment.
I am of the opinion that treatment alone or application of ergonomic principals by themselves was not going to resolve a repetitive stress injury.   
This article will address the implication of work station ergonomics and injury resulting from postural stress secondary to use of the computer mouse.
Specifically, the following will be addressed:
1)    What repetitive stress injuries are
2)    What role do work station ergonomics play in injury
3)    How reaching for the mouse sets the stage for injury
4)    What are the symptoms of repetitive stress injury
5)    How one can avoid mouse reaching injuries
What Exactly is a Repetitive Stress Injury?
Repetitive Stress Injury is a kind of catch all phrase for many conditions.  Carpal Tunnel Syndrome, Tenosynovitis / DeQuervain's Syndrome, Tendonitis, Thoracic Outlet Syndrome, Trigger Finger, Myofascial Pain Syndrome and Chronic Sprain / Strain are some of the actual diagnosis that are rendered in my office.  All of these conditions are serious and in many cases can cause great pain, permanent disability and sometimes loss of employment.
Repetitive Stress Injuries occur from repetitive movements involving a specific set of muscles and joints.  RSI injuries are the result of an accumulation of stress and strain that causes irritation, inflammation, and eventually pain or other disability.  A good analogy used to characterize the onset of RSI would be the “straws on the camels back” saying.
Initially, RSI affects the soft tissues of the involved joint(s).  Soft tissues include muscles, nerves, ligaments and tendons.  However, if left untreated for long periods of time, the involved joint can become arthritic and form bone spurs resulting in permanent damage to the joint.
While various occupations ranging from meat cutters to construction workers develop RSIs that result from the typical duties of their professions, the most frequent cause of these injuries involve computer work.  The constant demand of keyboarding and mousing combined with the postural stress of confinement in an office chair with one’s neck and back held in prolonged fixed positions has resulted in an epidemic of injuries that includes hand pain, wrist pain, arm pain, neck pain, back pain and shoulder pain. 
Work Station Ergonomics 
The study of workstation ergonomics tells us that the objects that are used most often should be located closest to your body and accessed easily, without awkward body positions.  Repeated reaching or prolonged postures that involve leaning forward from your chair are particularly stressful and fatiguing.
Many people are aware of computer ergonomics and thus have an ergonomic mouse.  An ergonomic mouse is of little use if it is positioned in an area that requires reaching and stretching in order to operate it.   Limiting reaching and stretching for desk items is essential to maintaining a healthy ergonomic environment.
The most frequent complaint that I have seen in my office is due to computer work is the combination of mousing and its’ inherent postural stress.
Most computer stations are designed in a way that involves the worker operating the computer mouse on a pad on the desk.  Reaching to the desk for the mouse places direct stress on the joints and soft tissues of the neck, shoulder, elbow, wrist and hand.  Additionally, reaching forward for the mouse stresses the lower and middle back.
So How Does Reaching for the Mouse Set the Stage for Injury?
Reaching for the mouse causes you to lean forward in your chair, extend your arm and support the weight of your body through your extended arm.  The following section will discuss the particulars of each of these positions.
The stresses placed on the human frame when reaching for the mouse are easily explained.  Contrary to popular belief, sitting, which most people believe is relaxing, is hard on the back. Sitting for long periods of time can cause increased pressure on the intervertebral discs of the spine.
In recent years, ergonomisist have told us that proper sitting posture would have us sitting upright with our hips flexed at 90 degrees.  As it turns out, the most up to date studies show that a slightly reclined sitting posture with the hips flexed at 100 to 115 degrees is ideal if you have to sit at a desk.  If your mouse is not positioned close enough to your body, you will have to reach for it.  Reaching for your mouse stresses your back by reducing the angle of your hips.
Next, we have to look at the effects of reaching on the neck and shoulder.  When the mouse is being operated at a distance that makes the operator reach, the shoulder extends forward and the shoulder blade abducts (rotates forward).  This position stretches the muscle groups that connect the medial portion of your shoulder blade to your spine and the superior portion of your shoulder blade to your neck.  In the short term, this stretch aggravates the affected muscle groups causing spasm, fatigue, headaches and stiffness in the neck and shoulder.  In the long term, this position creates a condition called a “stretch weakness” resulting in muscular imbalance, trigger points and chronic variations of the conditions listed in the prior sentence.    
Lastly, placing the mouse too far away, too low, or too much on one side can cause shoulder, wrist, elbow, and forearm discomfort. When the operator is forced to reach for the mouse, his / her body weight shifts forward and ultimately results in weight bearing stress on the extended arm.  Spending prolonged periods of time leaning on an extended arm is an unnatural and destructive posture that will eventually lead to the development of a repetitive stress syndrome; likely resulting disorders would include tendonitis of the wrist, elbow or shoulder.
What are the Common Symptoms?
•    Tightness, discomfort, stiffness, soreness or burning in the hands, wrists, fingers, forearms, or elbows
•    Tingling, coldness, night pain or numbness in the hands, especially around the base of the thumb
•    Clumsiness or loss of strength in the hands
•    Pain in the neck, shoulders, wrists, hands or back that is associated with using the computer
How Can You Avoid Injuries Related to Reaching for the Mouse?
The following recommendations are applicable to both home office ergonomics as well as ergonomics in the office.
1)  Placing the input device directly in your immediate reach zone offers natural comfort and maximum hand-eye coordination.  The use of a platform for the mouse is preferable.  Some models of mouse platforms attach directly to your chair.
2)  Your chair should have arm rests that are adjustable.  
3)  Your wrist should be either in a neutral position or flexed slightly downward when operating both your mouse and your keyboard.   For this reason, if you select a mouse platform that attaches to your chair, adjustability of the platform is of primary importance.
4)  Consider using a high quality office chair with adjustable armrests and lumbar supports.  It should also allow some degree of recline.
5)  Make sure that the upper arm and elbow are as close to the body and as relaxed as possible for mouse use - avoid overreaching.
6)  Hold the mouse lightly, don't grip it hard or squeeze it. Place the pointing device where you don't have to reach up or over very far to use it.  The closer you can place it to your body the better.

The Computerized Office and Its Effects on Workers

The Computerized Office and Its Effects on Workers
 Hundreds if not thousands of books and articles have been written that deal with the short and long term negative effects of working with computers.

As a chiropractor practicing in San Diego, I see a constant flow of new patients who complain of neck pain, shoulder pain, arm pain, wrist pain and hand pain as a result of long work days that mostly consist of sitting at a computer.  It doesn’t stop there.  Because sitting is especially stressful for the lower back we see plenty of computer operators who complain of low back pain as well.

It seems that the computer spares no body part from pain, discomfort and sometimes disability.

The most damaging characteristics of computer work can be summed up in two related triggers that stimulate our bodies to react to this type of work.

The first of these triggers involves the way the muscles of our necks, upper backs, arms and hands are used during computer work.

Whenever we are working on our computers our fingers are moving a mile a minute while the rest of the muscles of our upper extremities are in a static contraction.  Muscles are designed to move joints through an entire range of motion.  When we work at our computers these muscles simply contract to hold joints in a fixed position.  When muscles act in this way they build up lactic acid, become irritated and inflamed and eventually fatigue and become painful.  The long-term effects of this process include tendonitis, carpal tunnel syndrome, trigger finger, etc, etc.

The second trigger involves postural stress.  It is human nature to lean forward into our work.  Leaning forward improves our ability to see what we are working on.  This posture typically includes bending forward at the waist, rounding our shoulders forward and craning our necks forward.  Each of these body positions by themselves is capable of causing pain and discomfort.  When we are doing computer work it is not unusual to have all three of these postural stresses working on us at the same time.

Controlling these stresses is of utmost importance in order to prevent injury.  Taking short one or two minute stretching breaks for the arms and hands every twenty or thirty minutes is very helpful.  Icing the painful areas is helpful as well.  Finally, becoming aware of your posture and doing what you can to eliminate postural stress will help.

The Single Most Important Thing You Can Ever Do For Yourself!

Each day patients come to my Chiropractic Office in San Diego complaining of pain.  It may be neck pain, back pain, headaches, leg pain, arm pain etc. etc. etc. – you get it.
For the most part, these patients are not really responsible for the cause of their pain.  They were injured by a fall, a whiplash accident, a work comp related accident a sports injury or some other sort of accident.
That being the case, some are directly responsible for their pain – which takes me back to the title of this article – and the answer.  THE SINGLE MOST IMPORTANT THING THAT YOU CAN EVER DO FOR YOURSELF IS TAKE RESPONSIBILITY FOR YOUR ACTIONS!  INCLUDING YOUR HEALTH!
I will follow this statement by admitting that even though I have been treating patients and handing out advise on health for over 15 years that I do not always make the wisest choices regarding my own health.  I find this frustrating.  A recent example involves a soda that I bought the other day.  I succumbed to a craving. 
That soda was the inspiration for this blog post.
In the past, I have written at least one article on the ill effects of soda.  When I do cave in to my occassional desire to drink a soda, I usually hit the internet to review the reasons why it is so bad for us.
Years ago, I had given up coffee – all coffee – even decaf.  What I didn’t give up was caffiene.  I got my daily caffiene fix from diet Coke.  It took me awhile to figure it out but eventually I recognized that soda made me anxious.  Especially regular soda.  There came a time that I knew I had to give it up – for the sake of my health. 
For over five years I drank no coffee or soda.  I felt pretty good as a result.  My digestion was better, my anxiety faded and my feelings regarding my own health improved.
At this point I do have a soda once in awhile – which aggravates me to no end.
In researching the current literature for the ill effects of soda, I found an article that links soda to gout.  This article sited studies that indicate that drinking regular soda, not diet soda, has a significant effect on your chances of developing gout.  The study found that consumption of two or more soft drinks each day upped gout risk by 85%.  The same study found that one soft drink each day upped gout risk by 45%. Beer raises gout risk by 49% per daily serving. A daily serving of spirits raises gout risk by 15%.
For those of you who do not know, Gout is an extremely painful form of arthritis in which uric acid crystals accumulate in the joints.  It most commonly affects the big toe but commonly affects other joints in the leg.  While men are more likely to suffer gout than are women, a woman's risk greatly increases after menopause.  About one in 10 people over the age of 60 develops gout.
A gout flair up can cause weeks of suffering.  It is very severe pain.  I had a gout attack in the early 1990s and I can say that it was the worst pain I have ever had to endure.  My gout attack affected my big toe and recall excruciating pain with any kind of contact on that toe – sleeping was a nightmare.  Anytime the sheet touched my toe it sent me through the roof!  
Gout causes intense pain and swelling, one of the worst pains you can suffer.
This study has been significant because it is the first one that links these commonly consumed drinks to gout.  That being said, the study definitely links soft drinks to gout risk, but it does not prove that cutting back on soft drinks will lower that risk.
Wheather or not your family history predisposes you to gout formation or not, you have to realize that high-fructose carbonated beverages don't have any nutritional benefit what so ever. 
The association of gout with soda consumption is just one more reason to eliminate soda from our diets. 
The point of this article is to draw your attention to the fact that we have a tremendous amount of control of our own health.  By using the information that is readily available we can take responsibility for our health by making wiser decisions.  

•    Five or six soft drinks each week upped gout risk by 29%. The men who drank the most soft drinks had twice the gout risk of the men who drank the fewest soft drinks. That's comparable to the gout risk of men who drink two to four alcoholic beverages a day.

Sitting, Reaching and Posture

Sitting and reaching have a profound impact on your posture.  Both sitting and reaching stress the spine.  Reaching stresses both the spine, shoulder, elbow and wrist.  Sitting and reaching contribute to poor posture that can cause neck pain, shoulder pain, back pain and wrist pain.

Sitting has a negative impact on your back for several reasons.  Since our spines were made to move, it should come as no surprise that hours on end of sitting in a static position leads to injury.  

In addition to a lack of movement, the sitting posture itself is structurally stressful to the spine.  When we are standing upright, the lower back should have a sweeping forward curve which promotes stability by reducing pressure on the discs that separate our vertebra.  Sitting reverses the normal curve in our lower backs and increases the pressure on the discs leading to an increased chance of injury.

From a postural standpoint, the sitting position can promote rounded shoulders, slumping forward of the upper back and jutting forward of the jaw.  Not only are these postures unattractive but they contribute to the development of tendonitis and result in stretch weakness of the involved muscles.

There are volumes of information regarding ideal sitting postures both on the web and within other posts on this site.  Sorting out your posture with the use of a good ergonomic chair will help you maintain good posture and spinal health.  

Reaching at or beyond your normal arc of motion also contributes to poor posture and cumulative trauma type injuries, especially of the neck and shoulder.  It is vitally important to the health of your frame to keep objects that you use on a regular basis within easy reach.  Your phone, the mouse, stapler, etc., if used frequently through the course of your day, should be within your immediate reach.  Objects that are used less frequently can be kept farther away, closer to the edge of your comfortable reach. 

Take a good look at your work space.  Making a few simple changes will help save your posture and your spinal health.
