Yes I agree that precise voluntary activation of the pelvic floor and TA with integration into functional and more challenging positions and ADLs and education about the 'knack' / anticipatory bracing is beneficial for genuine SUI. I remember an article by Kari Bo (BMJ 1999;318:487–93) where training of the PFMs was superior to electrical stimulation and vaginal cones in
the treatment of genuine SUI.
As hypertonicity can often be missed in a diagnosis of solely PFM weakness I think that eccentric lengthening/ relaxation of the pelvic floor should also be a component of PFM exercises.
Best of luck and Thanks
