  The "ring" muscles, or sphincter muscles, are groups of muscles that contract and relax simultaneously. When they all work together, we are in good health. but when they stop working correctly, our bodies fall out of balance. different exercises will have different reactions on each body, a practitioner will diagnose and detect the best exercises that better react to the ailing part of the patient's body. The principle of Sphincter-Gymnastics is based on Paula Garbourg's observation that in the healthy body all the sphincters work together as one unit. In the healthy body all the sphincters contract and relax simultaneously, activating the respiratory system, gastrointestinal system and the urogenital system.

Effectiveness of Circular Muscle Exercise (Paula Method) Versus Keel exercises for Urinary Stress Incontinence was tested in a randomized controlled trial comparing two methods of exercise for the treatment of stress incontinence (loss of urine after physical exertion) in women. We are comparing the Paula method of circular muscle exercise, in which circular muscles controlling sphincters of the body (such as the eyes, mouth and rectum) are exercised, with pelvic floor training (Kegel exercises) in women in the community. The study hypothesis is that the effectiveness of circular muscle exercises is equivalent to pelvic floor training among women with this disorder.
Methods: 200 women who chosen from the community and suffering from SI entered the study to one of two arms. The first arm is the Paula method of circular muscle exercises: these women will receive private lessons from a registered Paula instructor. The system is based on activating circular muscles in the body. The results showed equivalent in improving the SI with the edition of a good effect for those who suffered from backache in Paula method.

The Book - The Secret of the Ring Muscles by Paula Garbourg was first published in Israel in 1979, has now reached its 18th edition.
