Resumo
The pelvic floor has been poorly studied from a biomechanical perspective probably because of its complex structure comprised of many muscle layers and multiple muscle insertions with concave format in a three-dimensional architecture. An objective assessment of the pelvic floor muscles’ (PFM) physical and mechanical capabilities is highly recommended to document changes in PFM function throughout rehabilitation protocols. Besides the magnitude of PFM force-generating capacity, other force/pressure-related parameters are important for the continence mechanism and sexual function, which are also correlated to different urogynecological dysfunctions. The existing devices for PFM assessment can be classified as manometers, dynamometers, electromyographers, or imaging techniques. So far, there is no perfect instrument or gold standard; however, each method has its advantages and disadvantages, and some of them will be discussed in this chapter. Recently, a new objective and reliable mechanical tool has been developed, being capable of measuring the magnitude and spatiotemporal distribution of pressures along the vaginal canal, taking into account the PFM structure, the directions of PFM contractions, and its ventro-cephalic resultant force. In this chapter, this device will be described and some of its clinical applications will be shown. © 2019 Elsevier Inc. All rights reserved.
