PERINEOMETER FOR DOMESTIC USE IN PREVENTION OF URINARY INCONTINENCE

Description

FIELD OF THE INVENTION

[0001] This invention relates to a novel perineometer for domestic use. More particularly, this invention pertains to a novel perineometer which can be used by a woman at home or in a non-medical environment for treatment and rehabilitation of pelvic floor muscles by pelvic muscle exercises (PME). The benefits include improved vaginal tone after childbirth, maintenance of sexual health, and prevention of some forms of urinary incontinence, specifically stress incontinence.

BACKGROUND OF THE INVENTION

[0002] Urinary incontinence is a major health problem that affects 50 to 70 percent of the institutionalized female elderly and up to 30 percent of all older female adults. The most common form is stress urinary incontinence. Stress urinary incontinence results from a sudden rise in bladder pressure that exceeds urethral resistance. This rise occurs under conditions such as coughing, sneezing or lifting. Appropriate pelvic muscle exercises have been found to strengthen the skeletal muscles, which increases the capacity of these muscles to exert pressure against the urethra, and thus reduce or eliminate urinary incontinence.

[0003] It has been estimated that one million Canadians, from all age groups, suffer from urinary incontinence and only one in five seek medical help. Because of this, the sale of adult diapers has ballooned into a multibillion-dollar industry in North America, with advertisements running on prime time television. Yet in most cases, urinary incontinence can be either cured or significantly improved. (Dr. Gary Naglie, a specialist in geriatric medicine at the Toronto Hospital, Toronto, Ontario, claims there are a variety of different treatments, including pelvic exercises, medication and surgery.) It is widely recognized among obstetricians and gynecologists that three treatments exist for urinary incontinence, including pelvic exercises, medication and surgery.

[0004] The number of people afflicted with incontinence is bound to swell with North America's aging population. But it can also strike those in middle age, particularly women whose pelvic muscles have been stretched by childbirth. Hormonal changes accompanying menopause can exacerbate the problem. Indeed, incontinence might well become the next-big health concern for many baby boomers.

[0005] There are three general categories of urinary incontinence - stress, urge and overflow. Each has a variety of causes and treatments. Learning techniques for better bladder control, or cutting back on caffeine, a bladder irritant, might be all that some patients require.

[0006] Certain drugs used to relax an overly sensitive bladder, which can be the underlying cause of urge incontinence, may cause unwanted side effects, including dry mouth, blurry vision, constipation and mental confusion. At the Toronto Hospital, Dr. Sidney Radomski said he and Dr. Naglie have found evidence that Nimodipine, a drug used to treat stroke patients, may relax the bladder without the unwanted side effects of other medications.

[0007] Surgery is another form of treatment for stress incontinence. Surgeons can now repair a sagging bladder by inserting miniaturized viewing equipment and surgical instruments through a few small incisions in the abdomen. Sometimes leaky bladders can be corrected with artificial sphincters or collagen injections. As a general rule, surgery should be avoided if other treatments are effective.

[0008] Arnold H. Kegel was among the first to document the positive effects of isometric exercises on the pelvic floor musculature (Kegel, 1948, 1952, infra.). Kegel recommended the use of perineometers for biofeedback in pelvic muscle training.

[0009] Simultaneous exercise with biofeedback has been proven successful and corroborated by several investigators. A large variety of perineometer units is available for clinical and physician office use. They generally use an intravaginal balloon to record vaginal pressure. Some form of visual or auditory feedback is displayed to the patient. This type of device is simple to use and is relatively inexpensive. A disadvantage is that careful training is required. Even so, the exercises may be performed improperly notwithstanding careful training. Patients who increase their intraabdominal pressure will also elevate their vaginal pressure. This falsely indicates the same measurable outcome as on isolated pelvic contraction. Thus, patients under professional care using perineometers must receive proper instructions and be evaluated professionally from time to time to ensure that their efforts result in a properly performed, isolated pelvic contraction.

[0010] Arnold H. Kegel, in his article entitled "Progressive Resistance Exercise in the Functional Restoration of the Perineal Muscles", which appeared in the American Journal of Obstetrics and Gynecology, Vol. 56, 1948, disclosed the first design of perineometer. A pneumatic apparatus was devised specifically for the exercise of birth canal muscles, with measurement of each muscular contraction visible to the patient. A chart was provided to keep a record of the accomplishment of each exercise period and serve as a progress guide for both patient and physician. The apparatus consists of a simple, balanced-resistance pneumatic vaginal chamber operating at atmospheric pressure and connected by means of rubber tubing with a manometer calibrated from 0 to 100 mm. of mercury. In construction, the vaginal chamber is an anode-processed rubber cot of specified consistency, lightly stretched over a rigid slender core with a flange at each end. An air vent in the core connects the pneumatic chamber with the tubing and manometer. The base of the chamber is fitted with a round, semirigid rubber shield 8 cm. in diameter, which limits placement in the vagina and permits pivoting into position.

[0011] Two laboratory procedures have been developed for the evaluation and treatment of pelvic muscle functions. Burgio et al. (1986) inserted catheters into the bladder to monitor bladder pressure and pressure balloons into the anus and rectum to monitor anal sphincter and intra-abdominal pressure, respectively. Discrimination training involved contracting the anal sphincter, which is commonly innervated with the pubococcygeal and other pelvic muscles, while relaxing the abdominal musculature.

[0012] A second medical laboratory and physician procedure was used by Dougherty and her colleagues (Dougherty, Abrams & McKey, 1986). They developed a fluid-filled intravaginal balloon device that is inserted vaginally and is connected to a pressure transducer that provides digital and visual information regarding pelvic muscle contractions. They also developed a pressure-sensitive posterior balloon device that is placed in the fornix of the vagina (Dougherty, Bishop, Abrams, Batich & Gimotty, 1989) as a measure of intra-abdominal pressures. Using these devices, and in company of physicians, or other qualified therapists, patients learn to discriminate and enhance pelvic muscle contractions while minimizing counterproductive abdominal contractions.

[0013] While Dougherty et al. have reported excellent reliability and reproducibility using their technique, it is unlikely that their technique will find widespread clinical use because of its time-consuming nature. However, the technique may be an important adjunct in clinical trials using pelvic floor exercise as therapy for urinary incontinence.

[0014] H. Gordon et al., in an article entitled "Perineal Muscle Function after Childbirth", The Lancet, July 20, 1985, disclose a perineometer for measuring perineal muscle function in European women one year after childbirth. The perineometer consists of a thin rubber condom, without a terminal teat, which can be inserted vaginally and inflated until the subject is just conscious of pressure. This gives the zero reading and subsequent pressure change is recorded on the gauge in cm water. The condom can be changed for each subject so the need for sterilization is eliminated, and it can be inflated to take account of variations in vaginal capacity. Once initial pressure causes the condom to inflate, the subsequent pressure needed to increase the volume is very small.

[0015] A number of patents have issued over the years disclose various designs of instruments for use in measuring perineal muscle strength, among other things.

[0016] DE 41 39 241 A (J. Steindorf), 27 May 1993, discloses a biofeedback apparatus which includes a microprocessor (4) which is programmed by a physician (see Figure 1). The disclosed apparatus includes a probe (1) which is primarily intended for use in the anus (see Figures 10 and 11, particularly) . The probe (1) for anal use, as shown in Figures 10 and 11, includes an inflatable bulb (61). By means of this apparatus, contraction exercises can be prescribed by a physician for an incontinent patient, coupled with a rectal expansion stimuli, whereby the patient after each observed rectal expansion, makes a contraction of the anal sphincter muscle and the pelvic floor muscles. Figures 9 and 9A illustrate a profile of a variable length probe sensor (1) which has an onion shape sensing head (11), connected to a slender cylindrical sensing stem (12), a depth limiting plate (13) and a handle (14). This embodiment is theoretically adaptable for vaginal use, but the stem (12) is not inflatable. The device, by having at one end a bulb (11) of a diameter that is larger than the stem (12), and a covering mesh (63), coupled with the inability to inflate the stem (12), makes the device unsuitable for enabling a patient to conduct active vaginal muscle strenthening exercises at home by squeezing the stem (12).

[0017] EP-A-0 219 410 (M. Duhem), 22 April 1987, discloses a monomeric catheter which is used, intsr alia, for active retraining of patients with urinary or anal incontinence. The catheter is designed for insertion into a body cavity (anus or vagina) and works in conjunction with the sphincteral muscle mass which is to be retrained. The catheter consists of a tubular, oblong elastically stretchable canula (7) framed by rigid anterior (4) and posterior (5) distal parts. The canula (7) contains an orifice connecting with an outside medium which is intended, when the catheter is functionally placed in the cavity, to be filled with a fluid which serves as a pressure transmission medium. The catheter includes a pair of electrodes (26) which are attached to the outside surface of the canula (7). The electrodes (26) contract and when charged with electricity cause the anal or vaginal muscles to contract. An apparatus (12) capable of monitoring electrical discharges from the two electrodes (26) is associated with the canula (7). A combination of the two electrodes (26) and pressurized fluid in the catheter (7) generates an outgoing signal. This signal is processed through electrical means and the magnitude of the signal is displayed on an illuminated display pad (26) corresponding respectively to pre-established pressure thresholds. The catheter (7) with the pair of electrodes (26), in combination with fluid filling the catheter, provides the correct electrical contact required for the transmission of electrical impulses to the adjacent muscular mass of the cavity, the electrical impulses being provided by electrical stimulation equipment.

[0018] The apparatus does not include a built-in training/exercise program. Moreover, the vaginal probe (catheter) requires exact positioning in the vagina because both ends are rigid and only the middle portion can expand under air pressure to provide resistance to the vaginal muscles. The Duhem apparatus also is deficient for home use because air pressure application is difficult, and potentially dangerous. No safety valve is provided. Also, it is debatable whether the syringe proposed as a source of compressed air can maintain 273 mm Hg pressure, as quoted.

[0019] A further shortcoming is that Duhem states a procedure where a given volume of air is placed in the bulb, and the resultant pressure is zeroed. It is not practical for the patient to begin exercises or tests at the same pressure. Large differences in response will result.

[0020] The present invention relates to a perineometer and accessories which can be used at home without direct medical supervision.

[0021] According to one aspect of the invention there is provided a perineometer for insertion in the vagina of a woman and enabling the woman to conduct pelvic muscle strengthening exercises under domestic conditions without direct supervision by a physician characterized by: (a) an elongate flexible non-electrically conducting pneumatically inflatable hollow vaginal muscular contraction resisting and pressure sensing bulb; (b) a flange associated with an end of the bulb; (c) a removable resilient silicone rubber or latex covering fitting on the bulb and the flange; (d) a manually pressurable air bulb with a pressure preset relief valve and manual air release valve connected between the manual pneumatic pressure bulb and the inflatable vaginal bulb for manually generating pneumatic pressure in the bulb; and (e) an instrument support connected to the vaginal bulb and pressurable air bulb, said support supporting a microprocessor, a source of direct electrical current, an electronic pneumatic pressure sensor, a manually manipulatable memory switch electronically connected to the microprocessor, an on-off switch controlling the transmission of electrical current from the electricity storage battery to the microprocessor, and an electronic digital readout display enabling a domestic user of the perineometer to monitor her performance on the perineometer.

[0022] The perineometer can include a program in the microprocessor which records past history of pneumatic pressure in the perineometer and enables the microprocessor to instruct the perineometer to return to the past pneumatic pressure level.

[0023] The microprocessor can include programming that enables the woman to monitor the strength, frequency and length of vaginal muscle contractions and rest intervals between contracting during the pelvic floor muscle strengthening exercises.

[0024] The vaginal bulb can include a non-electrically conducting resilient, hollow inflatable shell, and an internal elongated hollow air tube which enables air to be pumped into or exhausted from the interior of the resilient vaginal bulb. The shell of the vaginal bulb can have a sheath-like construction, with an opening at a first end, the opposite second end of the shell having in the interior thereof a semi-rigid resilient member for enabling the end of the hollow bulb to retain its shape in an inflated or non-inflated condition, and a semi-stiff resilient member at the interior region of the shell at the first end proximate the opening, and a seal sealing the opening of the vaginal bulb to the pneumatic pressure bulb. The vaginal bulb of the perineometer can include a flexible cover which removably fits over the shell.

[0025] The perineometer can include a flange mounted around the periphery of the air inlet and outlet tube adjacent the shell.

[0026] According to a second aspect of the invention, the manually pressurable air bulb is replaced by an electric air pump which is electronically connected to the microprocessor and enables the microprocessor to activate the electric air pump and pressurize the vaginal bulb to a pressure programmed into the microprocessor, a pressure preset relief valve being positioned between the air pump and the pressure sensing vaginal bulb.

[0027] The perioneometer can include a plurality of programmed pressure and relaxation sequences, which can be displayed on an electronic display panel, and can enable the domestic user to follow a program of perineal muscle contraction and rehabilitation procedures.

[0028] The perineometer can include an adjustable belt which can be worn by the domestic user to hold the vaginal bulb means in place in the vagina of the domestic user. The belt can include an adjustable length waist strap, an adjustable length crotch strap, and a means in the crotch strap for holding the vaginal bulb means. The waist strap and the crotch strap can have fasteners thereon which enable an end of the waist strap to be releasably secured to a body portion of the waist strap and an end of the crotch strap to be releasably secured to a body portion of the crotch strap.

DETAILED DESCRIPTION OF SPECIFIC

EMBODIMENTS OF THE INVENTION

[0030] Referring to the drawings, Figure 1 illustrates a schematic view of a manual perineometer according to the invention. This is suitable for home use. Written instructions, as well as optional video and CD-Rom instructions, are provided. Supervision by a physician, physiotherapist or other health care provider is not required. The perineometer is sold in association with detailed instructions for use, as well as an optional instruction video. The perineometer 2, of the invention, is constructed of a resilient inflatable vaginal bulb 4 which has a flange 6 which impinges against the vulva area of the woman. The flange 6 prevents the patient over-inserting the bulb 4 into the vagina and potentially causing physical injury. A manually pressable air bulb 10, with a high pressure relief valve and manual air release 12, is connected to the vaginal bulb 4 by first air tube 14. A digital readout board is connected to the air bulb 10 by second air tube 16.

[0031] The valved air bulb 10 and the relief valve 12 are important because they prevent any possibility of overinflation of the vaginal bulb 4, which a home use patient might do without professional supervision, even though full instructions are provided. This overinflation is especially possible with a patient who is commencing the program.

[0032] The readout board 8 has thereon a number of displays and manually controllable buttons. A manual on-off switch 30 can be manipulated by the home user to start or stop the electronics accompanying the perineometer 2. A manually manipulatable start-count button 42 enables the domestic user to start an electronic count to keep track of time in seconds and to count the number of vaginal contractions over a given time. The pressure of inflation of the flexible vaginal bulb 4 is disclosed in pressure readout 44. A running count of time in seconds is displayed in time display 46. The number of vaginal contractual counts is displayed on count 48.

[0033] As an option, the pressure indicator 44 can be programmed to monitor a prescribed inflation pressure and if the pressure exceeds that pressure, activate relief valve 12 until the pressure is rectified by lowering the air pressure to less than the specified pressure.

[0034] Figure 2 illustrates a detail schematic view of a perineometer exercise bulb 4 according to the invention. As seen in Figure 2, the vaginal bulb 4 is sheath-like and adapted for insertion into the vagina. It includes a semi-firm round-end cylindrical shell 17, which is sufficiently stiff that it will not collapse when inserted in the vagina. It can be constructed of a suitable plastic such as polyethylene or latex. The air impermeable, semi-flexible and inflatable shell 17 supports a removable covering 18, which is preferably constructed of or covered with a non-allergenic material such as silicone rubber. If need be, a conventional latex condom can be used, if allergies are not a problem. The shell 17 is open at one end and has extending therein an air inlet and outlet tube 20, which has a number of air ports 22 along its length. These allow air to pass into or out of the shell 17. Air inlet and outlet tube 20 is connected at the end opposite the vaginal bulb 4 to first air tube 14, as seen in Figure 1.

[0035] To ease insertion into the vagina by providing support, and for comfort, the sheath-like shell 17 has at the closed end thereof, in the interior thereof, a resilient end liner 24. A corresponding resilient inside liner 26 is contained within the end of the shell 17, proximate to the flange 6. This provides comfort in the area of the vaginal opening and eases withdrawal from the vagina. The covering 18 fits over the edges of flange 6, as shown at 19.

[0036] While not shown, the shell 17 and covering 18 may be of a laminated construction combining both strength and resilience, if such a design is required. It is also important that both the shell 17 and covering 18 have sufficient resilience that they can conform to the shape of the vagina of the individual patient, while at the same time, they have sufficient overall strength not to over inflate at any one particular region. Common balloons, for instance, have weak areas and can be made to inflate at certain areas, while other areas remain uninflated. This uneven inflation phenomenon is to be avoided with the bulb 4. However, the structure of the walls of the bulb 4 and shell 17 must be sufficiently flexible to ensure that the proper pelvic floor muscles are contracted or flexed on the bulb 4 and true consistent measurements are obtained.

[0037] The cover 18 should either be washable after single use or be removable and replaceable on a one-time use basis for reliability and hygienic reasons. It should also be of a material and design that it can be readily installed over the shell 17 and flange 6, and readily removable when desired.

[0038] Figure 3 illustrates a schematic view of electronics and instrumentation associated with the manual embodiment of the perineometer according to the invention. As seen in Figure 3, the electronics and instrumentation for the manual perineometer include a battery 28, which typically can be a rechargeable 2 to 12V cadmium battery, or a small large capacity long life 2V-12V lithium battery. The electronics should be such as to require only small voltage, for example 2 to 12 volts. Electrical low voltage current to operate the system can be delivered on an on-off basis via on-off switch 30, and electrical wires 32 to a microprocessor 34. The microprocessor 34 can be a conventional silicon chip type. The microprocessor 34 can be programmed using known programming techniques with operating instructions as well as a large almost unlimited number of alternative vaginal perineal muscle rehabilitation exercises if desired, or prescribed by a physician. For instance, one program can be a periodic series of five or ten second perineal muscle contractions, interrupted on a sequential basis by fifteen second pauses or relaxation periods. The length of each program in seconds and minutes can also be programmed into the microprocessor 34. Alternating periods of contraction and relaxation, the frequency thereof, and the pressure thereof, can be prescribed by a certified gynecologist.

[0039] The microprocessor 34 can also be programmed according to known techniques to record and display the perineal muscle rehabilitation history and progress of the domestic user. This program can be called up by manipulating memory switch 36. Program data, and history data are displayed on digital readout 8. A pressure sensor 38, which can be a conventional pressure transducer, with electronic converter, measures the air pressure in tube connection 40, which is connected to second air tube 16 as shown in Figure 1. A pressure safety limit can be programmed into the microprocessor 34 or can be built mechanically or electronically into the pressure sensor 38 or related hardware, according to known techniques.

[0040] Figure 4 illustrates a schematic view of an automatic perineometer 50 according to the invention. The automatic perineometer 50 as illustrated in Figure 4 does not require a manually manipulatable valved air bulb 10 (see Figure 1), and is entirely electronically controlled. A vaginal bulb 52, which is constructed in a manner similar to the bulb 4 that is illustrated and discussed in association with Figure 2, and a protective flange 54, are connected via air tube 55 to electronic readout board 56. The digital readout board 56 carries a trio of manually manipulatable pressure set buttons 58. These buttons 58 can be used to increase, decrease or maintain specific air pressures according to the needs of the domestic user or as prescribed by a qualified physician. A maximum pressure limit can also be programmed into the microprocessor for the safety of the home user.

[0041] The digital display board 56 also carries a manually manipulatable memory button 60, which the domestic user can press to cause the electronic memory of the microprocessor to automatically set air pressure in the perineometer 50 to the same level as used by the domestic user during a previous exercise. A manually operated program button 62 can be used by the domestic user to call up any one of a number of preset programs that can be programmed in the microprocessor. A manually manipulatable on-off switch 64 can be pressed by the user to either turn on or off the perineometer 50. The readout board 56 also carries a digital display panel which displays pneumatic pressure 66, time 68, measured in seconds, and vaginal contraction counts 70. Thus the domestic user can keep track of vaginal muscle contractions and relaxation frequencies and intervals, as well as pressure. The program, pressure, time intervals, and the like can be changed at any time.

[0042] Figure 5 illustrates a detailed schematic view of the electronics and instrumentation of the automatic perineometer 50 according to the invention. As can be seen in Figure 5, the electronics for the automatic perineometer 50 include as a power source an electric battery 72, which can typically be a long life lithium battery or a rechargeable nickel cadmium battery of 2 to 12 volts. Alternatively, the automatic perineometer can be powered from a conventional 110 volt alternating current source, with an adapter and transformer to reduce and alter the electrical current to 6-12 volt direct current. The electrical power supply to the perineometer from battery 72 is controlled via an on-off switch button 64 and flows along wiring 74 to a microprocessor 75. The microprocessor 75 can be programmed using accepted program techniques with a wide variety of selectable exercise and rehabilitation programs according to the needs of the domestic user and as prescribed by a qualified physician. Memory switch button 60, which causes the microprocessor 75 to command that the perineometer return to a previous pneumatic pressure reading or give a previous history, is manually manipulatable by the domestic user.

[0043] Program switch button 62 can be used by the domestic user to call up any one of a number of alternative exercise and rehabilitation programs programmed into the microprocessor. These are displayed on readout 66. If the domestic user wants to change the pneumatic pressure, the user can change the pneumatic pressure accordingly by manipulating manual pressure set buttons 58. A pressure sensor 76, is connected to the microprocessor 75 by line 81. By reading electronic information data from the electronic pressure sensor 76, the microprocessor 75 is able to control the pressure in the automatic perineometer to a previous level, maintain the pressure, or decrease or increase the pressure according to commands from the pressure set buttons 58.

[0044] A preset safety valve 78, which is positioned between the air pump 80 and the pressure sensor 76, ensures that pneumatic pressures in the automatic perineometer 50 do not exceed predetermined safety levels. An electrically activated bellows type air pump 80 is used to generate pneumatic pressure in the automatic perineometer 50. As seen in Figure 5, the bellows air pump 80 is controlled via line 84 by microprocessor 75. Tube connection 82 connects the bellows air pump 80, and other components, to air tubing 55, which is illustrated in Figure 4.

[0045] Dougherty et al., in their article entitled "Graded Pelvic Muscle Exercise", the Journal of Reproductive Medicine, 0024-7758/93, utilized a pelvic muscle exercise regimen for determining the effect of such pelvic muscle exercise on stress urinary incontinence in middle-aged and elderly women. The protocol required 16 weeks of exercise, 3 times per week, for a total of 48 sessions. The PME protocol began with sessions requiring 15 repetitions of a 10-second contraction of the pelvic muscles. Ten repetitions were added every four weeks, resulting in 45 repetitions during level 4. An audio cassette tape recording was provided to guide PME sessions.

[0046] A similar regimen, as well as other programs, can be programmed into either the microprocessor 34 of the manually inflated perineometer 2 or the microprocessor 75 of the automatic perineometer 50.

[0047] G. Elia et al., in an article entitled "Pelvic Muscle Exercises: When Do They Work?", which appeared in the American Journal of Obstetrics and Gynecology, Vol. 81, No. 2, February 1993, reported the results of an evaluation conducted during a 6 month period on 36 women with genuine stress urinary incontinence. Following clinical and urodynamic evaluation, the patients started an active Kegel exercise program. This was conducted by an experienced physiotherapist who enhanced motivation by working on positive clinical feedback and establishing a friendly sympathetic relationship. The subjects were instructed to contract the pelvic muscles for 10 seconds and then relax for 10 seconds. Each cycle of contraction/relaxation was performed in three different positions. The patients first would contract the pelvic muscles standing on their toes, then standing with legs abducted and elbows resting on a chair, and last in the supinedecubitus position with both hands on the abdomen to feel for abdominal muscle contractions. The purpose of the different positions was to avoid Valsalva-type efforts. The adequacy of the contractions was checked on a one-to-one basis by pelvic examination and perineometer; when the patients were considered ready, they started the group sessions. The training program lasted for 3 months and consisted of biweekly group classes for 1.5 hours during the first 6 weeks, and weekly sessions thereafter. The women were asked to perform the exercises at home for 15 minutes four times a day.

[0048] Similar programs, as well as other programs, can be programmed into either the microprocessor 34 of the manually inflated perineometer 2 or the microprocessor 75 of the automatic perineometer 50.

[0049] L.J. McIntosh, et al., in an article entitled "Pelvic Floor Rehabilitation in the Treatment of Incontinence", reported in the Journal of Reproductive Medicine, Vol. 38, No. 9, September 1993, reported the results and effectiveness of a pelvic floor rehabilitation program conducted on a sample of 48 women with follow-up interviews from 6 to 3 years. Patients with genuine stress urinary incontinence, unstable bladder and mixed incontinence showed 66%, 33% and 50% respective improvement rate. The strength and duration of pelvic muscle contraction was significantly greater between the first and last visits of all patients, regardless of the subjective improvement. The study concluded that a pelvic floor rehabilitation program was an effective alternative to surgical intervention in reducing the frequency of urinary leakage.

[0050] The original perineometer proponent, Arnold H. Kegel, in an article entitled "Early Genital Relaxation, new technic of diagnosis and nonsurgical treatment", which appeared in the November 1956, Vol. 8, No. 5, issue of the American Journal of Obstetrics and Gynecology, recommended the following regimen for using his original design of perineometer. After 5 to 10 correct contractions, the perineometer is inserted, and both physician and patient watch the manometer to note the results of her efforts. The woman may practise exercises with the apparatus in the office for 5 or 10 minutes, during which time the physician has an opportunity to check whether she is contracting according to instructions. The patient is instructed to exercise with the aid of the perineometer for 20 minutes, 2 or 3 times a day. Since frequent repetition is essential for establishing a new reflex pattern, the woman is advised to contract the same muscles without the apparatus 5 to 10 times every half hour, throughout the day, and to interrupt the flow of urine several times whenever she voids. Any of these programs, and others as well, can be programmed into the microprocessor 75 of the automatic perineometer 50 or the microprocessor 34 of the manual perineometer 2.

[0051] Some patients using the manual perineometer 2 may find they have some difficulty holding the perineometer 2 in position in the vagina while they are operating the air bulb 10 and doing their exercises. In this case, the patient may wish to use a belt to hold the perineometer in position.

[0052] Figure 6 illustrates a front view of perineometer support belt according to the invention. Figure 7 illustrates a perspective view of an assembled perineometer support belt according to the invention. As seen in Figure 6, the belt 86 is constructed of a flexible waist strap 88 and a right angle crotch strap 90'. A conventional hook and pile (Velcro™) fastener 94 is located at the free end of the crotch strap 90 and enables the user to secure the strap 90 snugly about her crotch. A slit 96 is located in the mid-region of the crotch strap 90. This slit 96 fits over the flange 6 of the bulb 4 and holds the flange 6 against the surface area of the vagina and the bulb 4 inside the vagina. The slit 96 also enables the tube 20 of the bulb 4 to protrude through the slit 96 and be connected to the perineometer. The belt 86 can be constructed of any number of flexible materials such as leather, plastic or cloth. Nylon woven belting that does not stretch is especially suitable.
