Injury Prevention Work Zone from ATI

All postures, positions and repetitive movements need to be interrupted, even good or ideal ones. However, the frequency of interruption and special considerations of work performed is determined by the amount of stretching required, the amount of load (weight) and the consequential risk for injury, sprain/strain of repetitive disorder.

The critical factors are: 

1. the height of your hands
2. the distance your hands are away from your body
3. the amount of weight or force
4. the frequency of the task
5. the time spent in the position
6. the presence or absence of warning signs
