Paperback book purchased from an internet site. ★ Purchase price: 1,320 yen ※ I accidentally bought two copies, so I will give one away to someone. (From the site description) This book, "Habits to Eliminate Sciatica," is compiled by Tetsuya Nakamura, a therapist who has supported sciatica patients for many years, to alleviate your pain and prevent recurrence. The "culprit" of sciatica that many people overlook is not the lower back or legs themselves, but a postural collapse called posterior pelvic tilt. The cause is the weakening of three muscles: the iliopsoas, the oblique abdominal muscles, and the latissimus dorsi. In this book, ・"5-minute emergency care" that can be done in the morning, afternoon, and evening ・Understanding "posterior pelvic tilt," which is essential for fundamentally improving pain ・"Hanedano-style high-voltage therapy" performed by experts are explained in an easy-to-understand manner with illustrations and examples.
