Investigation of optimal cues to instruction for pelvic floor muscle contraction: a pilot study using 2D ultrasound imaging in pre-menopausal, nulliparous, continent women.

Aims: Optimal urethrovesical positioning (UVP) may be important for continence. Pelvic floor muscle contraction (PFMC) influences UVP. PFMC instruction cues vary and often encourage anterior PFM recruitment that may result in sub-maximal posterior facilitation.
