The pelvic-floor muscles (PFM) play an important role in urinary and fecal continence. Several investigators have studied the PFM using intra-vaginal pressure measurements, but their methods have not been validated. We describe the characteristics of a probe transducer developed to measure PFM strength according to its dynamic response and the effects of temperature variation. This probe transducer was used to evaluate changes in the contraction strength of pelvic muscles in a group of patients who participated in a PFM training program. Experiments allowed the identification of the probe's characteristics at different temperatures, definition of a calibration equation, and measurements of the dynamic response to pressure pulse. Evaluation of patients before and after the PFM training program showed significant differences in the peak pressure achieved during the contraction (p<0.001) and in pressure-rise time (p<0.01). The tests performed with the probe allowed the characterization of the proposed transducer, and the intra-vaginal pressure measurements in volunteers undergoing a PFM training program allowed a quantitative evaluation of the PFM strength.

“…However, any positive effect of such treatment may be mediated by changes in the contractility and/or bulk of the urethral rhabdosphincter rather than of the levator ani. While the effect of pelvic floor muscle exercises (PFMC) on intravaginal pressures and muscle bulk of the levator ani can be determined relatively easily [24,25] and while such changes are associated with treatment response, it is not clear whether such changes are the cause of clinical improvement or just a marker for improvements in urethral structure and/or function.…”

“…6,7 Many randomized controlled trials and systematic reviews have shown that PFM training is effective for treating stress urinary incontinence, with success rates of between 44% and 80% among adult females. 8,9 However, there is little evidence that it can improve pelvic organ prolapse and its symptoms. 10 Some theories have been proposed in order to explain the mechanism of action of PFM training in pelvic organ prolapse.…”

Efficacy of pelvic floor muscle training and hypopressive exercises for treating pelvic organ prolapse in women: randomized controlled trialEficácia do treinamento da musculatura do assoalho pélvico e de exercícios hipopressivos para o tratamento do prolapso de órgãos pélvicos em mulheres: ensaio clínico randomizado. METHODS: Fifty-eight women with stage II pelvic organ prolapse were divided into three groups for physiotherapy: a pelvic floor muscle training group (GI); a hypopressive exercise group (GII); and a control group (GIII). The patients underwent transperineal ultrasonographic evaluation using a transducer of frequency 4-9 MHz. The (CSA) of the levator ani muscle was measured before physiotherapy and after 12 weeks of treatment. RESULTS:The groups were homogeneous regarding age, number of pregnancies, number of vaginal deliveries, body mass index and hormonal status. Statistically significant differences in CSA were found in GI and GII from before to after the treatment (P < 0.001), but not in relation to GIII (P = 0.816). CONCLUSIONS:The CSA of the levator ani muscle increased significantly with physiotherapy among the women with pelvic organ prolapse. Pelvic floor muscle training and hypopressive exercises produced similar improvements in the CSA of the levator ani muscle. CLINICAL TRIAL REGISTRATION NUMBER: NCT01196598reSUMO CONTEXTO E OBJETIVO: Estudos anteriores mostraram que mulheres com disfunção do assoalho pélvico possuem diminuição da área de secção transversal (AST) do músculo levantador do ânus. Uma forma de avaliar os efeitos de um programa de treinamento é mensurar a AST do músculo por ultrassonografia. O objetivo foi avaliar a eficácia do treinamento da musculatura do assoalho pélvico e de exercícios hipopressivos no aumento da AST do músculo levantador do ânus em mulheres com prolapso de órgãos pélvicos. TIPO DE ESTUDO E LOCAL: Estudo prospectivo, randomizado e controlado realizado no Ambulatório de Uroginecologia da Universidade Federal de São Paulo. MÉTODOS: Cinquenta e oito mulheres com prolapso de órgãos pélvicos estádio II foram divididas em três grupos para tratamento fisioterapêutico: (GI) grupo de treinamento dos músculos do assoalho pélvico, (GII) grupo de exercícios hipopressivos e (GIII) grupo controle. As pacientes se submeteram a avaliação ultrassonográfica transperineal com transdutor de frequência 4-9 MHz. Foi mensurada a AST do músculo levantador do ânus antes e após 12 semanas de tratamento fisioterapêutico. RESULTADOS: Os grupos foram homogêneos no que se refere a idade, número de gestações, número de partos vaginais, índice de massa corpórea e estado hormonal. Diferença significante foi observada na AST de GI e GII antes e após o tratamento (P < 0,001) e isso não ocorreu com o GIII (P = 0,816). CONCLUSÕES: A AST do músculo levantador do ânus aumentou significativamente com tratamento fisioterapêutico em mulheres com prolapso de órgãos pélvicos. Treinamento dos músculos do assoalho pélvico e exercícios hipopressivos são semelhantes no que se refere ao aumento da AST do...
