Reader Reactions (from Amazon reviews)

Since its release, Amazon has received numerous reviews from physical therapists and readers who have suffered from lower back pain for many years.

"Even from my perspective as a physical therapist, the content was easy to understand, and I finished reading it in one sitting."

"As I've gradually practiced the self-care methods introduced in this book, I can feel my lower back pain definitely lessening. I am truly grateful to have found this book."

"I was expecting it to be technical content and braced myself, but it was surprisingly easy for general readers to understand, and I learned one surprising thing after another."

In this book, the author, a physical therapist and head director of "Seituin Fukka," a clinic specializing in pain, explains the latest treatment methods for freeing oneself from lower back pain, based on his experience treating over 50,000 people. Focusing on the "true cause" that cannot be seen on X-rays or MRIs, he presents an approach to fundamental improvement from three perspectives: "muscles," "joints," and "brain's assumptions." This book is highly recommended for those who want to be freed from lower back pain and graduate from a daily life of masking pain with patches and medication.
