Abstract

A method of improving the pelvic floor muscle strength of a person in a manner to lessen urinary incontinence includes placing surface electrodes of electromyographic measuring apparatus on the perineum of the person, measuring with said apparatus the bladder controlling pelvic floor muscle strength of the person while the person is tensing the pelvic floor muscles in a urine stopping manner to obtain an EMG signal, and adjusting the threshold value of a portable electromyographic measuring unit to enable the person to repeat the measurement at different times to attempt to obtain better EMG signals in a urinary incontinence reducing sense. The portable unit gives an audible and/or visual indication when an EMG signal above the threshold value is achieved.

Claims

1. A method of improving the pelvic floor muscle strength of a person in a manner to lessen urinary incontinence comprising;

placing surface electrodes of electromyographic measuring apparatus on the perineum of the person,

measuring with said apparatus the bladder controlling pelvic floor muscle strength of the person while the person is tensing the pelvic floor muscles in a urine stopping manner to obtain an EMG signal, and

adjusting the threshold value of a portable electromyographic measuring unit to enable the person to repeat said measurement at different times to attempt to obtain better EMG signals in a urinary incontinence reducing sense, said portable unit giving an audible and/or visual indication when an EMG signal above said threshold value is achieved.

2. A method according to claim 1, comprising;

measuring with said apparatus the bladder controlling pelvic floor muscle strength of the person while the person is at rest and not consciously tensing the pelvic muscles in a urine stopping manner to obtain a first EMG signal, while the person is tensing the pelvic floor muscles in a urine stopping manner for a short period of time to obtain a second EMG signal, and while the person is tensing the pelvic floor muscles in a urine stopping manner for a longer period of time to obtain a third EMG signal.

3. A method according to claim 2 wherein the threshold value of the portable electromyographic measuring unit is adjusted to a value which is from about 60 to about 80% of the best measurement while the person is tensing the pelvic floor muscles in a urine stopping manner.

4. A method according to claim 2 wherein the short period of time is in the range from about 2 to about 5 seconds.

5. A method according to claim 4 wherein the short period of time is about 2 seconds.

6. A method according to claim 2 wherein the longer period of time is in the range of from about 10 to about 30 seconds.

7. A method according to claim 6 wherein the longer period of time is about 10 seconds.

8. A method according to claim 2 wherein the short period of time is in the range of from about 2 to about 5 seconds and the longer period of time is in the range of from about 10 to about 30 seconds.

9. A method according to claim 8 wherein the short period of time is about 2 seconds and the longer period of time is about 10 seconds.

10. A method according to claim 1 further including;

repeatedly applying neuromuscular stimulation in the form of electrical pulses to the pelvic floor muscles to cause the muscles to repeatedly contract and relax and consequently grow and increase in strength to lessen urinary incontinence.

11. A method according to claim 10 wherein stress incontinence is to be treated and said electrical pulses have a peak current in the range of from about 10 to about 100 milliamps and a frequency in the range of from about 40 to about 60 Hz and are applied in pulses lasting from about 5 to about 10 seconds with an interval between pulses in the range of from about 5 to about 10 seconds.

12. A method according to claim 11 wherein said electric pulses have a peak current of about 40 milliamps and a frequency of about 50 Hz and are applied as pulses lasting for about 5 seconds with an interval between pulses in the range of from about 5 to about 10 seconds.

13. A method according to claim 10 wherein urge incontinence is to be treated and the electric pulses have a peak current in the range of from about 10 to about 100 milliamps and a frequency in the range of from about 10 to about 15 Hz and are applied as pulses lasting from about 5 to about 10 seconds with an interval between pulses in the range of from about 5 to about 10 seconds.

14. A method according to claim 13 wherein said electric impulses have a peak current of about 40 milliamps and a frequency of about 13 Hz and are applied as pulses lasting for about 5 seconds with an interval between pulses in the range of from about 5 to about 10 seconds.
