This invention is directed, inter alia, to methods for treating urinary incontinence or frequent urination in a subject in need thereof.
Urinary incontinence or the loss of bladder control is a common and often embarrassing problem. The severity of urinary incontinence ranges from occasionally leaking urine when one coughs or sneezes to having an urge to urinate that is so sudden and strong one does not get to a toilet in time.
The three main types of urinary incontinence are: stress incontinence: occurs during certain activities like coughing, sneezing, laughing, or exercise; urge incontinence: involves a strong, sudden need to urinate followed by instant bladder contraction and involuntary loss of urine; and overflow incontinence: occurs when the bladder cannot empty completely, which leads to dribbling.
Incontinence is most common among the elderly. Women are more likely than men to have urinary incontinence. Infants and children are not considered incontinent, but merely untrained, up to the time of toilet training. Occasional accidents are not unusual in children up to age 6 years. Young (and sometimes teenage) girls may have slight leakage of urine when laughing. Nighttime urination in children is normal until the age of 5 or 6.
Normally, the bladder begins to fill with urine from the kidneys. The bladder stretches to allow increasing amounts of urine. The first urge to urinate occurs when around 200 mL of urine is stored in the bladder. A healthy nervous system will respond to this stretching sensation by alerting the urge to urinate, while also allowing the bladder to continue to fill. The average person can hold around 350 to 550 mL of urine. Two muscles help control the flow of urine: the sphincter must be able to squeeze to prevent urine from leaking. The bladder wall muscle (detrusor) must stay relaxed so the bladder can expand. When it is time to empty the bladder, the bladder wall (detrusor) muscle contracts or squeezes to force urine out of the bladder. Before this muscle squeezes, the body must be able to relax the sphincter to allow the urine to pass out of the body.
The ability to control urination depends on having normal anatomy, a normally functioning nervous system, and the ability to recognize and respond to the urge to urinate.

Additional objects, advantages, and novel features of the present invention will become apparent to one ordinarily skilled in the art upon examination of the following examples, which are not intended to be limiting. Additionally, each of the various embodiments and aspects of the present invention as delineated hereinabove and as claimed in the claims section below finds experimental support in the following examples.
After each change (calibration, positioning) in configuration in the protuberances attached to the footwear, the patient was asked to walk a distance of 10 meters away from the therapist and then back in order to verify that the patient remains balanced and that the change in configuration resulted in a desired positive effect.
The device comprises 2 units of footwear: one for the left foot and one to the right foot. The footwear used is a light walking boot.
Prescription included a set of instructions to the patients. These instructions included: the length of wear the device per day (usually 30-60 minutes daily). Daily use included wearing the device during routine activities that may include watching TV, computer activities; eating activities, etc. Actual walking constituted 10-25% of 30-60 minutes. Thus, if the patient has worn the device for 60 minutes per day, total of 5-10 minutes were dedicated, accumulatively, to walking.
A 74 years old woman is presented to the treatment center with a main complaint of urinary incontinence during physical efforts.
Case History: The woman reported that incontinence started after the birth of her third son, and worsened after each birth (she had 5 vaginal births). She reported that for the last 4 years she uses pads since whenever she coughs sneezes or lifts a heavy object she faces uncontrolled urination (urine leaks). A written evaluation from an urologist specializing in incontinence described a positive stress test.
Questionnaires: I-QOL score was 62 at baseline.
Bulbous protuberances with B convexity and “soft” resilience were connected and fixed under the hind-foot and fore -foot of the left and right footwear.
Balancing: The device was calibrated and fine tuned during repeated clinical gait assessments while the patient is wearing the device. During this process care is taken to reduce the eversion and inversion during heel strike, loading response, mid-stance and toe-off.
Heel-Rise Timing: The patient was asked to walk 20 m in order to confirm that she is still balanced and the heel-rise is well timed in the gait cycle. There were no abnormalities observed in heel-rise timing.
Treatment Plan: The patient was briefed with safety instructions and was asked to wear the system at home for 45 minutes a day on each day of the first week of the treatment. During this time she was instructed to be seated for most (80%) of the time, getting up occasionally to do daily activities such as answering the phone or getting a drink. Accumulative weight bearing time per day in the first week was 7 to 9 minutes (20% of total time with the system). The patient was instructed to increase the total wearing time by 15 minutes per week maintaining an accumulative 20% of weight bearing time with the device. The patient was seen for follow-up consultations at the center 4 weeks after her first visit, 10 weeks after her first visit, and 5 months after his first visit.
Treatment Progression: In the first follow up consultation the patient reported that she felt more comfortable performing indoors daily activities with the device than with her regular shoes. She reported that she found she did not have to get to the toilet quickly whenever she felt the need to urinate. Her I-QOL score was 74. She was then asked to increase the total wearing time of the system by 15 minutes per week and maintain the 20% accumulative weight bearing time. In the second follow up consultation the patient reached a total weight bearing time of 3 hours. She reported that she had significantly less episodes of incontinence when performing physical tasks such as lifting. Her I-QOL score further increased to 88. Her gait was clinically assessed and she seemed very well balanced. Her system was therefore calibrated so that the convexity of the anterior and the posterior right and left bulbous protuberances were increased to C level of convexity. She was asked to maintain the three hours of total wearing time for two weeks and then gradually increase the total wearing time up to 5 hours. She was also instructed not to limit her indoor activities while wearing the system, so that weight bearing time would potentially be more than 20%.
In the third follow up consultation she reported she has ceased to use pads for incontinence. She was wearing the system for 5 hours daily during indoor activities and reported she found it very comfortable. Her I-QOL score reached 96.
A 68 years old man is presented to the treatment center with a main complaint of increased urinary frequency and urgency.
Case History: The patient reports that he was diagnosed with a benign enlargement of the prostate 2 years ago. Since then he has an increased frequency in the need to urinate and reports that if he does not get to the toilet quickly he is incontinent.
Questionnaires: I-QOL score was 75 at baseline.
Bulbous protuberances with B convexity and “soft” resilience were connected and fixed under the hind-foot and fore -foot of the left and right footwear.
Balancing: The patients system was calibrated and fine tuned during repeated clinical gait assessments with the device. During this process care is taken to reduce the eversion and inversion during heel strike, loading response, mid-stance and toe-off.
Heel-Rise Timing: The patient was asked to walk 20 m in order to confirm that he is still balanced and the heel-rise is well timed in the gait cycle. A bilateral early heel-rise was observed. In order to correct this, a 2 mm hard spacer was fixed between the left posterior bulbous protuberance and the outsole of the left shoe in order to bring the left foot to a slight plantar-flexion, thus bringing the left foot into a more plantar flexed position. The patient was reassessed walking with the system and it was noted that the timing of the left heel-rise was normalized. At this phase a 2 mm hard spacer was placed between the right posterior bulbous protuberance and the outsole of the right shoe in order to bring the right foot to a slightly more plantar-flexed position. The patient was observed walking with the device and the timing of the right heel-rise was noted to be normalized as well.
Treatment Plan: The patient was briefed with safety instructions and was asked to wear the device at home for 45 minutes a day on each day of the first week of the treatment. During this time he was instructed to be seated for most (75%) of the time, getting up occasionally to do daily activities such as answering the phone or getting a drink. Accumulative weight bearing time per day in the first week was 9 to 12 minutes (25% of total time with the system). The patient was instructed to increase the total wearing time by 15 minutes per week maintaining an accumulative 25% of weight bearing time with the device. The patient was seen for follow-up consultations at the center 5 weeks after his first visit, 10 weeks after his first visit, and 6 months after his first visit.
Treatment Progression: In the first follow up consultation the patient reported that he felt comfortable performing indoors daily activities with the system. He reported the urgency to urinate reduced. His I-QOL score improved to 81. He was then asked to increase the total wearing time of the system by 15 minutes per week and maintain the 25% accumulative weight bearing time. In the second follow up consultation the patient has reached a total weight bearing time of 3.5 hours. He reported that he had significantly less episodes of incontinence and frequent urination and was able to restrain himself for longer periods of time. His I-QOL score further improved to 90. His gait was clinically assessed and it was found that he was very well balanced. The device was therefore calibrated so that the convexity of the anterior and the posterior right and left bulbous protuberances was increased to C level of convexity. He was asked to maintain the three hours of total wearing time for two weeks and then begin walking outside for 10 minutes in addition to the indoors wearing time. He was asked to increase outside walking by 5 minutes each week to a maximum of 40 minutes.
In the third follow up consultation he reported another substantial decrease in urinary urgency and incontinence. He was wearing the system for 3 to 4 hours a day during indoor activities and walked outside for approximately 35 minutes a day while wearing the system. His I-QOL score was 100. He was asked to continue using the system and return for a follow up consultation in six months time.
These examples present the unexpected benefit of the device in treating urinary incontinence and frequent/urgent urination.
