Feature Article: "BACK UP" - Tips on Back Safety
 
The spine is an integral part of our bodies. Not only does the spine allow us to stand upright and move as we do, but it is also the housing for our entire nervous system. Damage to the vertebral column can lead to decreased mobility and potential nerve damage to extremities. Your spinal column is at its lowest risk when it maintains an upright "S" curve. This posture allows an equal distribution of pressure on the intervertebral discs and allows muscle groups to be in their strongest position. Each vertebra is separated by intervertebral discs, which are made up of tough fibrous tissue with a fluid filled core. As we over-exert our bodies and put continuous demands on our spine we start to degrade the integrity of these discs. The beginning stages of disc degeneration affects the fibrous tissue. This tissue starts to loose water causing the discs to become brittle, flatter and not as strong. As disc degeneration progresses the "viscous internal fluid" from the core of the disc can rupture through the fibrous tissue (i.e., often known as disc herniation). This can lead to pressure on the spinal cord or the nerves that supply our body. (Grandjean, 1988) In order to extend the "life" of our spine we should try to maintain an optimal back posture at all times. The following are several "BACK UP" tips for work and home:
 
Standing:
  Stand shoulder width apart with one foot ahead of the other
  Keep stomach muscles firm
  Maintain the neutral "S-curve" of the spine
  Don't stand with legs locked
  Wear appropriate footwear with supportive soles or inserts
  Use a foot support or elevate one foot to relieve back pressure
  Stretch - give your back a break (MASHA, 2000)
Sitting:
  Ensure that back is upright
  Position lumbar support in the small of the back
  Place feet firmly on the floor or on a foot rest
Driving:
  Avoid "slumping over" when driving
  Maintain the "S-curve" in your back
  Position the seat to allow for adequate leg room
  Avoid over reaching for the steering wheel
  Relax your shoulders while driving
  Use a cushion or a rolled up towel to support the small of your back
  On long trips stop and stretch
Sleeping:
  Mattress should be soft for the first few inches and firm underneath
  Sleeping on your back - place a small pillow under your knees
  Sleeping on your side - knees should be at 90° and a pillow should be placed between knees to reduce twisting of the spine
  Sleeping on you stomach - should be avoided, however by placing a pillow between your hips and shoulders and using a small pillow or no pillow will help reduce strain on muscles and ligaments
Lifting/Carrying:
  Grip the load and lift with a straight back and bent knees  
  Keep the load as close to the body as possible    
  Lifting should occur between knee and shoulder height    
  Avoid rotating or twisting    
  Lift and carry the heaviest part of the load close to the body    
  Loads should have handles or allow for a good, secure grip    
  Whenever possible, use an assist (hoist, trolley etc.)    
  Ask for help when loads are heavy    
  Stabilize your body and prepare for the lift    
  Do not jerk loads - lift using a smooth motion    
  Test your load - know what you are lifting    
  Review your surroundings and plan you route    
Lifting/Carrying:    
  Whenever possible, push rather than pull to reduce strain on the spine    
  Keep body close to the cart/object    
  Do not lean into the cart; maintain a neutral posture    
  Use both arms to push a load    
  Keep stomach muscles tight (MASHA, 2000)    
Workplace Solutions:    
  To reduce bending for loads, use height adjustable pallet lifters, tables and / or carts    
  Avoid manual lifting - use hoists, cranes, carts, pallet trucks or fork lift trucks    
  To minimize reaching, place large bins on turn tables    
  Use bins with fold down or removable sides    
  Avoid storing heavy items below the knee or above the shoulder    
  Use conveyors, air tables, chutes, ramps, slides or easy glide surfaces to help move loads
