Effects of Indirect Pelvic Floor Muscle Activation Exercise Using a Pressure Biofeedback Unit on Trunk Muscle Activity in Sitting Position

Abstract

The pelvic floor is composed of muscles, ligaments, and fascia that span the area underneath the pelvis. The pelvic floor muscles (PFMs) include the endopelvic fascia, levator ani, and urogenital diaphragm, which support the pelvic organs and play an important role in urination control and sexual function. Weakness of the PFMs can cause common musculoskeletal disorders experienced by women such as incontinence and back pain. Interventions to address PFMs weakness include PFMs exercises, bladder training, prompted voiding, and lifestyle modifications. PFMs exercises improve muscle function by repeated contraction and relaxation of the PFMs. PFMs activation restores the normal position of pelvic organs and contribute to trunk stability. The PFMs co-contract with the transverse abdominis Effects of Indirect Pelvic Floor Muscle Activation Exercise Using a Pressure Biofeedback Unit on Trunk Muscle Activity in Sitting Position
