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.

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.
