hi! concerning to the statement, that when pat. stands, feels like something falls out, i would suggest that pelvic floor is weak. I would start to show here exercises for pelvic floor muscle strengthening. Also you might show her some techniques for mild coughing and sneezing to minimize the abdominal pressure. also a study in our hospital (Emons et.al, if i remember it right) with the galileo 2000 vibration therapy divice showed that pelvic floor, abs and back muscles can be trained very well using vibration therapy.
but also menopause might be a reason for her problems. ask her if she have/had any postmenopausal problems or if she takes hormon replacement therapy. Also rule out all other things like back/disc problems, cauda equina syndrome etc. just in case and to be sure, that all this is fine.
cheers
