While Dr. Kegel's paper is very informative, it is also exhausting reading. Here's my layman's attempt at summarizing it:


A Nonsurgical Method of Increasing the Tone of Sphincters and their Supporting Structures

ARNOLD H. KEGEL, M.D., F.A.C.S.
Assistant Professor of Gynecology
University of Southern California School of Medicine
1948

 

Background

Through experience as a surgeon and research with cadavers, Dr. Kegel had noted that the pelvic muscles of women were often weak and thin from disuse. He theorized that just as we exercise other body parts to tone and improve the strength of weak muscles, surely there must be a way to repair these muscles that way as well-- instead of resorting to surgery, which was not effective long-term anyway.

He focused his attention on the pubococcygeus, nicknamed PG. He describes it as the most versatile muscle in the human body. It helps support all the pelvic organs, helps the muscles that control the openings, and is essential for maintaining the tone of the other pelvic muscles. The PG gives off countless fibers which interlock and insert themselves into the muscles of the urethra, middle third of the vagina and rectum.

When a patient's organs were in the right positions, the PG and its components would be found to be well developed. When the muscles were weak and thin, symptoms like uterine prolapse (uterus falling down), incontinence and sexual disfunction would occur. The next step is to test whether a patient can voluntarily contract various muscle groups. First he would have them retract and draw in the perineum (the diamond-shaped area corresponding to the outlet of the pelvis, containing the anus and vulva.) Next, the index finger is inserted to the middle third of the vagina (as above) and the patient is asked to squeeze it. A normal patient can immediately respond with a firm grip felt over a wide area. Others will state that they didn't know it was possible to contract those muscles. These patients will have the most weakened muscles.

Dr. Kegel would quantify this response using a device he developed called a Perineometer. It was inserted in the vagina and could measure the pressure exerted by contractions of the vaginal muscles. In a well developed vagina, a slight rise in pressure is detected when the device is inserted, without any patient effort. In weakened patients, this initial pressure is much lower. The pressure change caused by intentional contractions were then measured. Strong, immediate increases in pressure indicated a strong, well-developed PG. A weakened PG resulted in small or even imperceptible increases in pressure with attempted contraction.

Therapy

He points out that it is super important while doing these movements to make sure the patient is actually contracting the PG muscles and not just the muscles around the outer edges of the openings. He points out that women with poor PG function have compensated all their lives by depending on these external, surface muscles. So the goal is to focus more inward and upward, so that the inserted finger feels the contractions as these movements are made.
 

Most patients can learn pretty quickly to find these muscles, but some may require weeks of this practice. There is no point in further therapy until this can be done.

Diagnosis

A firm vaginal canal indicates that the fibers of the PG are well developed. Loss of tone and and prolapse of the vaginal walls indicates that the PG fibers are weak and thin. You can test the vaginal muscles by inserting an index finger into the vagina, up to about the second joint, so that you are feeling the middle third of the vagina. In a normal vagina, the canal is tight and the tissue resists from all directions. The walls naturally close around the finger. The walls feel firm and deeply attached to the surrounding tissue. On the other hand, if the middle of the vagina is roomy in all directions, regardless of whether the opening is wide or tight, and the walls offer little resistance to touch and feel thin and loose, this indicates that the PG fibers have weakened from lack of use. 

Education

The first step in therapy is to help the patient find and learn to activate the muscles. He found that 1/3 of patients could not contract their PG voluntarily on the first visit. He would use a process of pushing with a finger at different internal locations to prompt the patient to contract the correct muscles. He'd basically find a connected muscle that they could contract and then work from there towards the PG. This teaches the patient to find and feel these disused muscles. For continued practice, the patient is directed to squeeze the inserted finger, draw up and in the perineum, draw up the rectum as though checking a bowel movement and contract as though interrupting the flow of urine. 
 

Resistive Exercise

Dr. Kegel felt that patients were unlikely on their own to be able do continue to use the correct muscles without help and supervision. He also felt that without measurable results, they were likely to become discouraged and stop exercising. So he recommended his Perineometer for contraction practice at home. It provided resistance to the muscles that needed strengthening and provided measurable results. Patients were advices to use the device for 20 minutes, 3 times a day. They were also encouraged to do additional contractions without the device throughout the day. He found that 50% of patients would slip back into their old habit of using the external muscles, so he recommended weekly appointments for the first month to firmly establish proper technique. He found that most complaints of fatigue and aching muscles were due to improper technique. 

Results

Patients who dutifully did their exercises experienced the following changes: stronger and more sustained contractions, thicker muscles throughout the pelvic area, improved positioning of the pelvic organs, firmer and longer vaginal walls, and reduced uterus prolapse. Patients with urinary incontinence showed dramatic results. 212 patients with severe urinary stress incontinence were treated and 84% were able to establish good urinary control through the therapy. 

The widest application is for women with genital relaxation after childbirth since 30% of women complain of this condition. Previously, women had to just suffer through symptoms until after menopause when surgical intervention would be recommended. Dr. Kegel found that progress was a slower with these cases, probably because since their symptoms were less debilitating they are less motivated and more haphazard in their exercise. But patients who were diligent felt improvement after 2-4 weeks of exercise but exercises needed to be continued longer to build lasting, structural changes. 

Preventative use

Pelvic resistance exercise during pregnancy builds thicker, stronger muscles, resulting in easier postpardum repair and less postpardum relaxation.

Exercise is also recommended after any pelvic surgery to help return muscles to working condition.

 

Conclusion

I noticed this statement in his conclusion, "On the basis of therapeutic results achieved, it seems possible that other ill-defined complaints referable to the genital tract in women might profitably be studied from the standpoint of muscular dysfunction."
