How did this happen? At times you expect it. After hours of stacking firewood, shovelling the driveway or trying to lift something too heavy you're not surprised to feel painfully stiff and sore. The injury makes sense to you, and while the pain can be severe you're pretty sure you know why it happened.  Better yet, you think that by knowing what caused the injury you'll be able to avoid it in the future. If you just pay someone else to shovel the driveway or stay away from lifting furniture, you can avoid the next episode. But, at other times the pain comes without warning and without provocation. Everything seems to be going smoothly when, for no good reason, something goes horribly wrong.  Maybe you sneeze, or you bend over to pick up a sock and suddenly feel severe pain.

How did this happen and how can you avoid the pain if it comes on randomly? These are questions I hear frequently, and unfortunately many reading this article can relate all too well.  Well, there might actually be some logic underlying these painful episodes, and understanding why they happen is your best chance at avoiding them in the future.

There are several different factors that play a roll, but the three primary factors in this equation are strength, endurance and coordination so lets take a look at each one.

Strength: Lack of strength and excess strain, such as simply lifting something too heavy, is an obvious way to pull a muscle or rupture a disc. Surprisingly, however, simple overload is the least common cause of injury.

Endurance:  Endurance, or lack thereof, might be the most common cause of back injuries  Lifting 50 small boxes can do just as much damage as one big box because fatigue can make you sloppy.  As you get more and more tired your technique starts to suffer, you start bending awkwardly and that is when the injury happens.

Coordination: Poor coordination or proprioception is another significant injury trigger and often the cause of those unexpected episodes. Proprioception is the ability to know where your body is without looking – its what allows you to touch your finger to your nose with your eyes closed.  Imagine driving your car, with good control you stay in the middle of your lane and watch for traffic. However with poor control you might end up swerving to the edge of the ditch at one point, then almost into the guardrail the next.  It's obvious which one is more likely to end up in a crash if a car pulls out unexpectedly. Your back can suffer exactly the same way.  With good coordination you hold the joint safely as you bend to get that shoe from the back of the closet, but with poor proprioception you might think that you are bending in a safe way, but actually you have put your back in a risky position, one were the slightest nudge or slip can push you over the edge.

The last part of the puzzle is simply luck, or in scientific terms probability.  To go back to our car accident analogy – you might drive to work every day for 10 years without ever having a problem, but then one day someone runs a light and hits your car.  You ask “Why me? What did I do?” In reality you did nothing wrong at all, but probability tells us that everything comes with a risk and sometimes accidents just happen.  Your body is much the same. We regularly do things that might be risky, most of the time getting away with it, but eventually we get caught.

When you add all the factors together you can sum up your overall risk of injury, however none of the factors are black/white options.  As you fatigue the risk of injury goes up, if you are strong the heavy box is relatively easy to lift, with better coordination you are less likely to get hurt.  Add in probability and even the simplest activity could result in an injury if its just not your day!

The good news is that with the right exercises each factor in the equation can be improved.  We can build core strength and endurance and improve coordination with proprioceptive training to make sure you're as ready as you can be when life just happens.
