This is a very simple, indirect manual therapy technique.
It is painless if done right, and can be done safely even when there is inflammation, which makes it an excellent choice for treatment even a few days after most injuries.
After a traumatic event, the nervous system can go into panic mode, sending pain signals everywhere.
Essentially, a pain-free position is found in an injured area and held there for a period of time, giving the nervous system time to re-think the issue and sort the signal from the noise.
It is particularly helpful in the beginning stages of recovery to be able to locate the areas of actual injury and begin to treat them. Recovery times tend to be much shorter the sooner these areas can be identified and addressed.
