I have not resceived it myself. The nearest I have come is colonic therapy.
But I have for a long time collected medical stories from real life or said to be from real life. Because I have so much of them now that I am able to compare and perform both a source critic and an exegetic work on them. I tend to believe most of them, after a certain exegetic analysis.
And here comes some fact as I see it:
Teenagers and young adults attending sport clubs and sport schools aiming for champioship sport or attending dance schools will often resceive pelvic floor therapy combined with therapy of the joints to enhance flexibility and performance.
In these cases they use all the intimate openings available: Urethra, vagina, anus.
They use all type of available treatment modalities: Colonic, urethral sounds, inflatable catheters, vaginal sounds, anal sounds, speculum, medical vibrating dildos, vaginal inflatable balloons, anorectal inflatable balloons, finger massage, inflation of bladder or anus with fluids, depot drug injection.
The therapy session often begins with colonic. Then proceed with endoscope and ultrasound which not only serve to examin, but also as therapy devices. Then one or more of the other modalities.
Of cource they do not use all these modalities in one session or on the same patient, but choose a few of the modalities.
The aim is to make the intimate area, the urinary system and lower digestive system optimally flexible for performing sport or dance, and to make the urinary system and lower digestive system work like a clockwork so that residual urin or stool do not cause problems for the performance.
I also have several account of this type pf therapy is used on kids with behavior problems. It may seem strange, but I have several accounts of it.
Often these sessions are done under deep sedation so that the person is uncoscious or deeply relaxed, and often do not fully know what is done.
