Anything that puts pressure on the abdomen can weaken or damage these pelvic muscles. Such conditions include pregnancy, childbirth, excess weight, hormonal changes, and aging.
Kegel exercises enable the PC muscles to better withstand increases in intra-abdominal pressure (pressure inside the abdomen). They make the bladder, urethra, and vagina more resilient, and improve bladder control and sexual relations.
Thirteen to 20 million American women suffer from urinary incontinence, primarily stress urinary incontinence (SUI)—urine leakage while laughing, coughing, sneezing, standing up suddenly, or exercising.
SUI occurs when intra-abdominal pressure increases and the urethral sphincter opens inappropriately. During pregnancy, the fetus puts pressure on the bladder and the sphincter may relax and leak.
Postpartum incontinence may result from muscle and nerve damage during childbirth due to delivery of a large baby, prolonged labor, excessive pushing, a forceps delivery, or an episiotomy (an incision made during delivery to prevent tearing of maternal tissue).
About 40% of American women suffer from incontinence after childbirth, and the incidence increases by about 12% following each birth. Childbirth also increases the risk for incontinence later in life.
During menopause, as a result of lower levels of estrogen, women with SUI may have thinning of the lining of the outer urethra, a sensation of having to urinate often, and recurrent urinary tract infections (UTIs). Beginning Kegels in midlife can help prevent urinary incontinence later.
By 1948, Dr. Arnold M. Kegel, a Los Angeles-area obstetrician and gynecologist, was having his patients practice vaginal contractions in preparation for childbirth. That same year he invented the Kegel perineometer, or pelvic-muscle sensor, to help prevent urinary incontinence (leakage) following childbirth.
Kegel’s perineometer was the first biofeedback machine designed for clinical use. Employing a vaginal sensor, an air-pressure balloon, and a tire gauge, it enabled patients to verify that they were performing Kegel’s correctly and to monitor their progress.
The patients continued their practice at home. Kegel published numerous papers on his work and claimed to have cured incontinence in 93% of 3,000 patients. He produced a documentary movie to teach the procedure to other physicians.
However, his perineometer was never marketed effectively and there was a widespread misconception that Kegels could not be performed without it. In the 1970s, more sensitive electromyography (EMG) perineometers became available for those with severely debilitated pelvic muscles.
- increased pelvic support
- restoration of vaginal muscle tone and improved vaginal health
- protection from the physical stresses of childbirth
- restoration of sexual function and improved sexual response and pleasure
- increased vaginal-wall thickness and lubrication after menopause (cessation of menstruation)
- prevention or reversal of urinary leakage and rectal incontinence
- relief from pelvic pain or pain of vulvar vestibulitis (inflammation of the vaginal opening)
Locating the PC muscles
The PC muscles can be felt by:
- stopping and starting urine flow to identify the forward PCs
- squeezing the vagina to identify the back of the PCs
- squeezing around two fingers placed in the vagina
- imagining sucking a marble up the vagina
- preventing a bowel movement or the passing of gas by tightening the muscles around the anus
There is a pulling sensation when the correct muscles are contracted. Weaker and stronger contractions are practiced until the PC muscles can be squeezed at will.
There are numerous suggestions for practicing Kegels, which include:
- Contracting the PC muscles for three to 10 seconds and relaxing them three to 10 seconds for five to 15 repetitions, three to 12 times per day.
- Contracting the PC muscles strongly for one second, then releasing for one second, 20 times, three times per day, speeding up the contractions until there is a fluttery sensation.
- While emptying the bladder, stopping the urine flow at least three seconds, 10 times during each urination, which provides 60–80 contractions per day.
The complete exercise requires muscle contraction from back to front. It may take three to eight weeks for noticeable improvement. Once good muscle tone is achieved, Kegels may be performed just once a day.
The PC muscles can be exercised at almost any time—while lying down, sitting (in the car at a stop light, at work, etc.), squatting, standing, or walking— and varying the exercise position is said to be most effective. Sitting or standing adds weight to the exercise.
It may be helpful to perform a Kegel squeeze before coughing, standing up, or lifting a heavy object. It may also be helpful to incorporate Kegels into a daily routine and keep a log. It is recommended that pregnant women practice Kegels regularly before, as well as after, childbirth.
Squeezing with two fingers in the vagina will confirm that only the vaginal muscles are contracting. Placing a hand on the lower abdomen is a reminder to keep the belly soft and relaxed, to refrain from tightening other muscles such as the stomach, buttocks, or leg muscles, or to hold the breath, all of which increase intra-abdominal pressure, working against the Kegels.
Brands include FemTone Weights, Kegel Weights, Kegel Kones, and Perineal Exerciser. Sequentially heavier cones are used until a maintenance program is established. This method automatically uses the correct muscles. Some of these products require a doctor’s prescription.
Biofeedback devices and electrical stimulation
Nerve damage may prevent some people from performing Kegels properly. Vaginal or anal sensors and EMG perineometers with computerized visual or auditory feedback displays can measure the PC contraction.
A handheld over-the-counter product (called the Myself pelvic muscle trainer) costs about $90. Another device can send mild electrical impulses to help locate the PC muscles.
With a vaginal sensor and biofeedback monitor, two 20-minute sessions per day for seven to nine months-with a specific goal such as holding 45-microvolts for 60 seconds—can relieve vulvar vestibular pain in the majority of women.
Insurance may not pay for EMG biofeedback therapy; however, Medicare will reimburse the patient if conventional Kegel exercises have failed.
Training may be provided before initiating a Kegels routine.
A temporary loss of muscle and nerve function following childbirth may make Kegels more difficult. Kegel exercises do not work if abdominal, thigh, or buttock muscles are contracted.
Furthermore, such contractions can increase pressure on the bladder, aggravating incontinence. Vaginal cones are not recommended in the presence of infection, neurological damage, diuretic medicines, or caffeine.
There are no side effects to Kegel exercises.
Research and general acceptance
When performed properly and consistently, Kegels are usually helpful. The United States Agency for Health Care Policy and Research recommends that behavioral methods, including Kegels and biofeedback, be utilized to treat urinary incontinence before initiating drugs or surgery.
Randomized controlled studies have shown that as many as 50–90% of women can reduce or overcome SUI with Kegels alone. However, reports of effectiveness vary since many people do not receive proper Kegel instruction. Consistent use of vaginal cones can improve or cure incontinence within four to six weeks in 70% of women.
The use of Kegels to improve urinary incontinence in men has not been extensively studied, although many clinicians report improvement. One study found that after the removal of a cancerous prostate, men who performed Kegels twice a day regained bladder control faster than those who did not do the exercises.
