The following post comes to us from Herman & Wallace faculty member Allison Ariail, PT, DPT, CLT-LANA, BCB-PMD, PRPC. Allison authored "Use of transabdominal ultrasound imaging in retraining the pelvic-floor muscles of a woman postpartum" and is a leading expert in the use of ultrasound imaging for pelvic rehab. She is the author and instructor of the Rehabilitative Ultrasound Imaging: Women’s Health and Orthopedic Topics offered with Herman & Wallace.
In the pelvic floor series we learn how to perform examinations for cystoceles and rectoceles. It can be more difficult for therapists to examine and quantify the degree of uterine descent. In the last few years translabial ultrasound imaging has also been used to identify what is happening in the anterior compartment upon Valsalva and pelvic floor contraction, including the uterus. This is helpful when trying to determine the degree of uterine prolapse. Degree of pelvic organ descent visible on by ultrasound has been shown to have a near-linear relationship with measures on the POPQ.
Clinically we see that some patients with severe prolapses have few symptoms, while other patients with smaller prolapses will have more severe complaints of symptoms. This can be puzzling to the clinician who is trying to treat prolapse patients. Shek and Dietz performed a study to set cutoff measures of uterine descent that will predict symptoms of prolapse. Translabial ultrasound imaging was performed on 538 women with 263 women reporting prolapse symptoms. Seventy-five percent of the women presented with grade two or greater prolapse on the POPQ, with most of being cystoceles or rectoceles. The women with more complaints of symptoms of prolapse were more likely to have uterine prolapse. There was a strong association between degree of uterine descent and symptoms of prolapse. They determined that an optimal cutoff to predict symptoms of prolapse due to uterine descent is a cervix descending to 15 mm above the pubic symphysis.
This study intrigues me and makes me wonder how much we are focusing on cystoceles and rectoceles and not looking at uterine prolapses. Using translabial ultrasound imaging is a nice tool to allow the clinician to see what is going on with all of the pelvic organs. With one Valsalva maneuver you are able to assess a lot of information including support of the pelvic organs. It also gives the clinician another way to quantify the degree of prolapse. Ultrasound imaging is a wonderful tool that clinicians can use for assessment as well as a biofeedback tool. If you are interested in learning how to perform this type of assessment, I will be teaching Rehabilitative Ultrasound Imaging: Women’s Health and Orthopedic Topics May 1-3 in Dayton, OH.
