Today, pelvic floor muscle assessment and training has been popularized in developed countries and regions such as Europe, America, Japan and Korea. In particular, pelvic floor muscle training is routinely performed for maternal, obese and elderly women, thus greatly reducing the incidence of pelvic floor dysfunctional diseases such as pelvic organ prolapse and urinary incontinence. At the same time, the nerves and muscles of the pelvic floor are awakened, so that the vagina can return to a tighter state, thus improving the quality of sexual life, pleasure and orgasm. Pelvic floor muscle function training can be performed in the following cases: 1. Postpartum women can do regular pelvic floor muscle exercises. 2. 2.Vaginal laxity, vaginal spasm and unsatisfactory sex life. 3.Mild or moderate uterine prolapse and vaginal bulge. 4.Various kinds of urinary incontinence. 5.Recurrent vaginitis, urinary tract infection patients in non-acute stage. 6.Urogenital repair adjuvant treatment. 7.Puerperal symptoms (low back pain, abdominal pain, urinary retention, breast rise, separation of pubic symphysis, etc.). 8.Muscle dysfunction of the whole body motor system. 9.Breast laxity, breast sagging. 10.Lower limb edema, venous and lymphatic reflux disorders. 11.Post-operative scar pain. How to perform pelvic floor muscle training? Pelvic floor muscle exercise is also known as Kegel exercise. The method is to do the action of tightening the anus, tightening for not less than 3s each time and then relaxing. Do it continuously for l5-30min, 2-3 times a day; or do PFME 150-200 times a day for 6-8 weeks as a course of treatment. Pelvic floor muscle training needs to take into account five aspects: 1, strength, muscle contraction can produce the maximum tension; 2, rate, the ratio of maximum tension and the time required to reach maximum tension; 3, duration, muscle contraction can continue or repeat the length of time; 4, repetitive, can be repeatedly contracted to achieve a certain number of tension; 5, fatigue, maintaining muscle contraction to achieve the required or expected tension to produce fatigue. Class I fiber training, mainly for the strength, duration and repetition of these aspects; Class II fiber training, mainly for the strength, rate and fatigue of these aspects. The pelvic floor muscle exercise: the above-mentioned content is more, seemingly complex and difficult to remember, commonly known as contraction, lifting the anus, women sitting in the office or standing waiting for the bus can do, each time for 3-5 seconds, relax a little and then repeat, morning and evening for 15 minutes each. Women can also try it in the middle of urination, if they can interrupt urination, it is also a good action to contract the anus.
