Your Child’s back pack and postural hygiene

Parents may not be aware of the hazards in selecting the wrong backpack for their children. There are many hazards which include; internal rotation of the shoulders, which leads to long term poor posture, muscle strain and localised irritation to the spine and ribcage, changes to the natural curve of the spine and an increased risk of falls because the child is forced to lean forward due to heavy or off balanced load.


  1. Backpacks should be 15-20% of your childs own weight. For example if your child is 25kg then the back pack should not exceed 5kg. (If your child is slumping forward its a sign the pack is too heavy)
  2. Make sure you distribute the weight evenly. Pack heavy items at the bottom to ensure that the heaviest load is carried lower and closer to your child’s core area.
  3. Padded shoulder straps prevent the strap from digging into their shoulders and back.
  4. Adjust the back pack to fit close to their body, but do not over tighten to pull on shoulders.
  5. Carry the backpack on both shoulders. Carrying a bag  over one shoulder forces other back muscles to compensate for the uneven weight distribution. As the spine leans to the opposite side to counter balance the weight. Over time this muscle imbalance will cause muscle strain and back pain. Neck muscles can also be affected, which may lead to neck pain and headaches.
  6. The top of the backpack should be below the neck and 5-7cm above the waist.
  7. Be aware of the contents of their backpack. Limit items to what is needed for that day. Kids tend to accumulate items in their backpacks without realising it.
  8. Place odd-shaped items in the front section of the backpack to avoid direct contact with your child’s back.
  9. Encourage your child to lift the backpack with his or her leg muscles and avoids bending the back.

Smoking and your spine

Smoking and the use of nicotine negatively affects all systems and tissues in the human body. People know of the dangers such as heart disease, lung disease, stroke and increased risk of cancer. What is less know is that smoking damages the vertebral column and spine, causing intervertebral disc disease and accelerating osteoporosis.

The intervertebral disc?
the intervertebral disc connects adjacent vertebral bones. These discs are shock absorbers between each vertebrae. The disc provides alignment and spinal stability, while absorbing compressive forces and enabling movement between spinal bones.

Nicotine use and degenerative disc disease:cairnschiropractor-osteoporosis
The connection between smoking and back pain in adults has been prove by decades of research.
Degenerative disc disease is a condition where the vertebral discs are compromised and weakened, Their function to act a s a cushion between vertebrae has been significantly reduced. The discs become softer, less efficient and more susceptible to injury. Degenerative discs can develop naturally as part of the ageing process or as a result from injury. Degenerative discs usually commence with micro annular tears, which do heal but leave scar tissue, which is not as strong as the original disc wall. Over time, the process of tearing and scarring ultimately weakens the disc wall. The inner portion of the disc known as the nucleus is fluid rich and its this hydrated structure that functions as a shock absorber. The nucleus can collapse causing the spinal bones to move closer together, resulting in improper alignment. This improper alignment can lead to arthritic changes, bone spur formation, herniated discs and pinched nerves, all of which cause pain.
The use of nicotine may be directly responsible  for disc degeneration, by causing damage to the nucleus and annuls. This impacts the long term health and functional ability of the discs. All these harmful changes mean that smokers not only damage healthy discs but also accelerate the degeneration in pre-existing damaged discs.

Osteoporosis and smoking:
Osteoporosis arises from the Greek term “porous bone” It is a bone thinning disease identified by loosing too much bone and replacing enough new bone. This decrease in bone tissue leads to frail weak bones which are at risk of fracture.
Spinal fractures are the most common types of fractures as a result of osteoporosis.

Many studies have associated smoking with decreased bone health. Tobacco smoking has been proposed to inhibit the activity of osteoblasts. Smoking is an independent risk factor for osteoporosis. Smoking also has secondary affects upon advancing osteoporosis. It increases the breakdown of exogenous estrogen, lower body weight and causes earlier menopause, all of which contribute to lower bone mineral density.
Studies have found that females who smoked more than a pack per day throughout adulthood had on average 5-10% lower bone density than non-smokers in the low back by the time they reached menopause. Second hand smoke has been shown to reduce bone mineral density. Smoking accelerates the loss of bone density in all bones, and the rate of loss is related to the daily number of cigarettes smoked and years of exposure. This is an independent risk factor from other factors that contribute to bone health such as sex, age, weight, BMI, and unhealthy lifestyle habits. For smoking alone, the risk of a spinal fracture is increased by 32% in men and 13% in women. Smoking also delays fracture healing. This is caused the toxic activity of nicotine which inhibits the growth of cells essential for healing and reduces blood and oxygen supply to the injured tissue.

Quitting smoking can be difficult. These five steps be the START of every successful plan to quit smoking.
•    Set a quit date.
•    Tell family, friends and co-workers you plan to quit.
•    Anticipate and plan for the challenges you will face while quitting.
•    Remove cigarettes and other tobacco products from your home, car, and workplace.
•    Talk to your doctor about getting help to quit.

Chiropractic: Joint “cracking”

Chiropractor Cairns often gets asked, “is cracking knuckles bad for you and what is the popping sound”?

Even though it sounds like it, no bone is actually breaking. People think this because we use words to describe what something sounds like.

As this video indicates “cracking” or joint separation is a rapid creation of the gas filled joint space, this vacuum formation results in an audible popping sound, due to the collapsing bubble.

Synovial joints throughout the body are very similar and they include neck and back joints.

It takes about twenty minutes for the gas to regenerate in the joint cavity before it can be popped again.

There is no evidence to suggest popping or cracking joints can lead to arthritis.

Cairns Chiropractic would like to illustrate the structures involved with sciatica.

The Sciatic nerve (L4,L5,S1,S2) descends between the ischial tuberosity and greater trochanter of the femur.

Symptoms may include weak hamstrings, leg and foot muscles. Sensory loss may also occur in thigh, leg and foot. Pain is associated with sciatica in thigh, leg and foot.
