Your mom needs to exercise her sphincter by doing kegels. It could be that her sphincter is inflammed and is causing her loss of control. I also highly recommend that she visits a rectal physical therapist. They can identify what part of the sphincter needs toning and prescribe direct exercises. If you can't find a rectal PT look for a pelvic floor PT. As for the burning, get a tube of calmoseptine ointment. It's the best for leakage.
