Since posting this thread, I have been reading up on electrical stim for pelvic floor rehab, and found Laycock J et al (2001) Clinical Guidelines for PT Mgt of females 16-65 with Stress Urinary Incontinence, Chartered Soc of PT, London.

Thanks to whoever posted the link - it is really useful, from both a theoretical and practical perspective.

re ES: it says electrical stim is useful for people with grade 0/1/2 pelvic floor contractions. (By grade 3 they could focus on active PFX's). It also makes suggestions about treatment parameters.

I still haven't found out exactly how ES improves pelvic floor neuromuscular facilitation or muscle action for long term treatment effects. From what I read, ES seems to be a passive kick start for the pelvic floor muscles which needs to be followed by active / volountary effort by the client. Anyone have more light on the subject?
