Pregnancy weakens the ligaments that keep the pelvic bones together. If these ligaments become overloaded, pelvic instability can result, leading to pain around the joints that may last for weeks or even years. Cecile Röst, a physical therapist, has devised a treatment program that is simple to undertake and has a 90-percent success rate. Her book is in two parts. Part One uses over 100 illustrations to illustrate symmetry and stabilization exercises to control the pelvis, and the best positions for sitting, standing, lying, and other daily activities. The exercises do not cause any pain and can be done at home or under supervision. Part Two is for care providers and gives background information about pelvic pain, a protocol for a first consult, and advanced details of the therapy. In Holland, where this treatment originated, physicians and obstetricians are enthusiastic about the author s work, and many women buy the book to take to their care providers.
