Hi Heather, I was just wondering if the tens machines are useful for pelvic floor rehabilitation. I've heard you can have a vaginal stimulation attachments and they are very helpful with strengthening the pelvic floor muscles after childbirth. Hi Yes TENS are great for also strengthening the pelvic floor and can be used six weeks after birth. You will need to purchase either a pelvitone TENS or the Femme Elite TENS for pelvic floor strengthening. See website for details: http://www.TENSPainRelief.com.au regards, Heather
