The present disclosure provides devices that noninvasively monitor the activity of pelvic floor muscles during labor, and in embodiments also provides perivaginal tissue support. electrode sensors are applied to perivaginal tissue and, in embodiments, a perivaginal support device during labor. The electrode signals are analyzed to estimate an efficacy of voluntary pushing and the efficacy is used, at least in part, to predict a success of vaginal birth. A pressure detection system may also be included with the perivaginal support device to detect pressure indicative of pressure on the perivaginal tissue of a patient, which may be modified to prevent tissue damage to the patient. The incidence of Cesarean childbirth may be reduced by managing the labor process in this manner. In one aspect, a tactile feedback device is positioned adjacent the perivaginal tissues.
