Is Your Problem Mobility or Flexibility?

Is Your Problem Mobility or Flexibility?

Have you ever watched a baby roll around and grab their feet and put their toes in their mouth.  

Their flexibility is incredible. I would love to have flexibility like that, and no, not to put my toes in my mouth :)

Flexibility VS Mobility.

Flexibility is the passive range of motion through a joint. For example if you were to bend your wrist back with the opposite hand, forcing it as far as it can go.

Orthotics - Are they necessary?

Orthotics - Are they necessary?

Orthotics are a custom made insert to help moderate the structure and function of your foot.  Whether they are necessary or not is something we will get into in a minute.

First off, all orthotics are not created equal.  They come in many different shapes and sizes, and can be made from different materials.  In some cases such as for diabetic patients, orthotics should be made with soft cushioning, and in other situations they may be as hard as a rock.

Low Back Pain in Dogs?

Low Back Pain in Dogs?

Determining where the root problem in a dog can be difficult.  They can’t explain to you what they are feeling and they don’t have fingers to point where it specifically hurts.

When I see injured dogs as an animal chiropractor, I am usually presented with a dog that has very common symptoms like limping or change in activity levels, but it usually comes with no diagnosis of what is happening… and I totally get why.

What is the difference between adjusting a dog and a human?

What is the difference between adjusting a dog and a human?

First off the principle of chiropractic care is the same for both.  A human and a dog both have a spine and nervous system. The function of their spine directly affects the function of their nervous system.  The nervous system is in control of muscles, organs and sensory function. In everyday life problems with this can show up in performance, mobility, or daily routine.

Should You Sit On An Exercise Ball?

The trend of swapping your office chair for an exercise ball seems to be fading a bit.  However, many patients still ask me if it is beneficial to sit on an exercise ball rather than a chair.  The exercise ball is an unstable surface that in theory should lead to increased trunk movement which aids in the nutrition of your muscles and vertebral discs and increases the activity of your core musculature.  There are other proposed benefits as well, but let’s find out if they outweigh the negative side effects.

A 2009 study published in the journal Applied Ergonomics, researchers compared an adjustable office chair with armrests to an exercise ball while the participants did a one hour typing task.  The chair and the ball were fit to the subject’s body size so when sitting their knee angle was 90 degrees.  As hypothesized by the authors they found 33% more global trunk motion when sitting on the exercise ball (not found to be significant).  They also found the average rate of change of lumbar EMG and amplitude of lumbar spine muscles to be 66% and 38% higher when on the ball.  Although increased spinal movement and muscle activation are good for spine health, they also increase forces on the spine, which can have detrimental effects on the intervertebral discs.  To test this, the authors looked at the compressive forces on the spine and found that spinal shrinkage was significantly greater when sitting on an exercise ball than the office chair.  Another implication of increased muscle activity is that it can lead to muscle fatigue which can increase your susceptibility of low back injury. 

Another study by McGill published in 2006 in Applied Biomechanics, looked at pressure distribution.  Comparing an exercise ball, an office chair, and a stool they found that the surface contact area was significantly greater with the exercise ball.  The increased contact area actually increases the level of discomfort when sitting on the ball.  This is because the soft tissue is now absorbing the pressure of sitting, when it should be on the boney part of your butt! 

In conclusion, although there seem to be benefits of sitting on an exercise ball, the benefits are outweighed by the significant negative effects to your spine.  For this reason use a traditional office chair at work or utilize an exercise ball for short periods at a time to limit the shrinkage of your spine!

If Your Dog is Fat, You Are Not Getting Enough Exercise

By this time next year I should be certified in veterinary chiropractic.  It's a year long course for both chiropractors and veterinarians. I'm excited to work with house pets like dogs, but I'm also excited at the opportunity to work with larger farm animals like horses.  

In light of my excitement and my love for animals I thought I would produce this post.  Enjoy!

The health benefits of having a dog are obvious.  Mentally they make you laugh and give you unconditional love when you are only gone for 30 minutes, they make it seem like you have been gone for 30 days.  But first I’m going to touch on the physical health benefits. Whether it is play, walking or jogging, you are forced to get off the couch and move.   Many studies have shown that owning a dog can help to avoid a sedentary lifestyle.  Increasing regular exercise, such as leisure walking can help to decrease the risk of certain cardiovascular conditions.  One study showed that pet owners have lower systolic blood pressure which is the driving force of the contracting heart, than non-pet owners.  Another study showed lower plasma cholesterol levels, as well as triglyceride levels in pet owners.   It is even reported that dogs may show adverse behaviour if their Type 1 diabetic owners are having hypoglycemic episodes which could help their owner avoid an adverse health event.   Finally, pet owners who suffered a heart attack had higher 1 year survival rates than their non-pet owning counterparts.   

More intriguing perhaps than the cardiovascular benefits are the psychological benefits of owning a pet.  Most pet owners do not get a pet to reduce sedentary behaviours but rather to have companionship and an improved quality of life.  In a study that followed just under 1000 participant for one year, it was found that pet owners had fewer doctor contacts than their counterparts without pets.  It has also been reported that certain populations of people that own pets suffer less from depression.  

The authors of one article proposed a theory of how pet companionship can improve cardiovascular health, by reducing emotional stress.  Increased emotional stress leads to a barrage of negative effects on the body.  This is caused by increased sympathetic nervous system function.  We developed this over thousands of years when we had to worry about Saber Tooth Tigers.  If you turned a corner and met up with a tiger you would instinctually fight back or run away (fight or flight).  Nowadays the Saber Tooth Tiger comes in the form of commuting, work deadlines, family stressors etc.  Short durations of this type of emotional stress is good because it can help us get away from the Tiger.  However, when long lasting, this type of stress can lead to chronic disease.  Among other things like exercise, owning a pet can psychologically decrease or limit stressful sympathetic activity.  This decreases potential endothelial dysfunction, chance of cardiac arrhythmias and sudden death, as well as high blood pressure through decreased kidney activity. 

If you train with your pet make sure that they are getting adequate rest and recovery. And for the same reasons that you should be taking care of your health by visiting a chiropractor, you should also be taking your dog to an animal chiropractor.

Until next time, stay healthy my friends!

Setting Up a Work Station

Many people suffer from the constant strain of poor posture.  This article will give you the optimal set up at your work station.  However, it is important to understand that any posture will at one point lead to fatigue.  Therefore small changes in posture and micro-breaks throughout your workday will give you most relief. The following information is from the Ontario Ministry of Labour website.

Computer monitor should he at a height to allow your neck to be straight (top of screen at eye level).  If you wear bifocals the screen should be slightly lower so head is neutral when reading the top line on the screen

There should be a 90 degree bend at your elbows, with your arms hanging naturally at your sides

Your hands should be in line with your forearms, so there is no bending of your wrists

Your thighs should be parallel to the floor, allowing your feet to rest flat on either the floor or a footrest

Your chair should have a lumbar (low-back) support to help maintain your natural lumbar curve in the seated position

Your mouse hand should be supported so there is no bend in the wrist

Use a document holder that is adjustable, to the same height as your monitor

 

Although the above is helpful, less people are using desktop computers as the popularity of laptops increase.  With the screen and keyboard connected, the screen will be too low, the keyboard will be placed too high or a little bit of both.  This means the importance of micro-breaks increase, and more frequent changes in posture will be needed.  

If you follow the above protocol you will put yourself in a less compromising position.  However, you still will put your neck in a compromising positioning.  Losing the normal curve in your neck can cause headaches, neck stiffness, numbness and tingling into the arms and hands as well as shoulder pain. If you suffer from any of these symptoms you should seek out a corrective care chiropractor who can assess your neck and let you know if you would do well under care.
