There are hundreds of simple processes that can be done on injured or sick individuals to help them recover. These are called "assists."
An Assist works by restoring communication between the being (a spirit) and his or her body, or the environment. Assists can save lives.
For example, if you ever stumble upon someone who has just died — a drowning victim — perhaps, if you act quickly (before the brain is damaged from lack of oxygen) you can sometimes "bring them back" because the being is still in contact with the body. if you know the person's name, shout his name and command him loudly to "get back here and bring this body to life." The Bring Back to Life assist is shown in an LRH film entitled Assists which now can only be seen within the CoS. But there you go, I just gave you the tech of this VERY simple and easy to do assist that can save someone's life.
Some of the most well known assists include the Touch Assist, Locational, Nerve Assist, Body Comm, Hellos and Okays, and many more. There are also assists for people who have suffered a loss and even an assist for a couple (husband and wife) who has just had a fight (which can sometimes be traumatic).
Some day a Scientologist should open a center across from a hospital offering Assists to walk ins. They'd get plenty of traffic and help a lot of people since doctors frankly are not focused on restoring communication, yet this is a major issue in the recovery process.
There was a book published for Assists in the early 1990s which included more than 100 assists, explaining how to do each one all nicely indexed. This is a great book to have if you can find out.
