Dr. Pamela Morrison contributed a chapter entitled “Musculoskeletal Conditions Related to Pelvic Floor Muscle Overactivity” to this just published book on Overactive Pelvic Floor Muscles. Overactive pelvic floor muscle dysfunction was previously termed pelvic floor muscle hypertonicity. It is a major cause of pelvic pain and can be related to or caused by other musculoskeletal issues. Congratulations to the editors Talli Yehuda Rosenbaum and Anna Padoa and to all others who made contributions!
