Firstly, am sorry that this book is out of print, for it provides critical information to people who wants to help their family members and friends recover from brain injuries that are happening so frequently throughout the world.
This book, and the information it contains, is a gift to humankind. For I have personally witness people who are functionally blind, mute and immobile got themselves to read, talk, & walk with the procedures described.
The book gives a good overview on the principles out of which treatment procedures are developed. These treatment methods are primarily formulated at the Institutes for the Achievement of Human Potential in Philadelphia. Many people around the world go to the Institutes for help. The programs are considered extremely challenging to do. It requires a lot of determination, love as well as pure & simple sanity.
