EMT's often need to hold stabilization. This requires them to hold an injured body part in one place for long periods of time. However, often times EMTs need to hold stabilization on their knees. Being unable to move and holding still while on one's knees, is very uncomfortable and hurts a lot. As a result, EMTs often accidently move to find a position of comfort. This runs the risk of causing even more damage to the injured body part. Additionally, this causes a lot of knee problems for EMTs.
