PFM_1a: Excellent image, transverse plane of pelvic floor muscles (PFM) showing funneling
PFM_1c: Previous image, arrow pointing out vaginal canal as landmark
PFM_2: Patient with elevated BMI, note depth required to fully image midline structures
PFM_3a: Demonstrating location of obturator internus
PFM_3b: Previous patient, PFM relaxed
PFM_3c: Previous patient, PFM contracted demonstrating elevation of midline pelvic contents
PFM_3d: Previous patient, showing downward deflection of bladder base during active SLR
PFM_4a: Male patient, sagittal view, PFM relaxed
PFM_4b: Male patient, sagittal view, PFM contracted
PFM_5a: PFM relaxed, showing resting measurement of bladder
PFM_5b: PFM contracted, measurement of bladder displacement, maintaining consistency in probe angle is essential
PFM_7a: Moderately obese female with PFM at rest, note poor support of the bladder base in comparison to other PFM images
PFM 7b-poor-support-contracted
PFM_7b: The same patient as the previous image, PFM contracted, note improved support of bladder base more like resting position in other PFM images
PFM_7c: The same patient as previous, observe complete loss of bladder support during active straight leg raise
PFM_8: Asymmetry of PFM observed in transabdominal view, note hypertrophy of left side, internal palpation demonstrated short-painful PFM on the left
