A Customized System to Test Pelvic Floor Muscles Contraction: A Proof of Concept

Studies show that there is a high prevalence of pelvic floor dysfunctions which negatively affect the quality of life of people who suffer from them. The few sensory mechanisms that pelvic floor muscles have to inform the brain of their situation can make it difficult to perform voluntary contractions or identify risk factors. Currently, there is no consensus to improve this proprioception. This work introduces the development of a novel intravaginal device that is connected to a mobile data acquisition system and able to discern the correct contraction of the pelvic floor muscles versus contraction of adjacent muscles or abdominal thrust efforts. A cross-sectional pilot clinical study has been carried out to validate this end with healthy adult nulliparous woman with good pelvic floor muscles contraction capability in supine position.Clinical relevance- The proposed system allows a personalized and real-time assessment of the contractile capability of the pelvic floor muscles (PFM), distinguishing between muscular plans (deep/superficial PFM), between sides (right/left PFM), and between pressures from the PFM and intra-abdominal muscles (IAP). The development of an intravaginal device which is able to simultaneously measure all these features is an important advancement in this field since it can provide information in real time on the contraction capability of all the PFM as well as on the influence of the IAP during different PFM exercises.
