I am struggling with this, where it seems my puborectalis muscle is tigt according to my pt. It seems that when I go to have a BM, sometimes it’s like it closes on me . I am aware biofeedback can correct this with pt. Does it have to be internal biofeedback or does external work as well? My pt doesn’t have an internal biofeedback machine, but I would like to get started asap with getting better until I can find someone who does. Would I be able to do just the external biofeedback for now? What else do you recommend?
