OBJETIVO: Verificar o efeito da adição do biofeedback (BF) ao treinamento dos músculos do assoalho pélvico (TMAP) para o tratamento da incontinência urinária de esforço (IUE). MÉTODOS: Estudo piloto prospectivo, randomizado e controlado, com mulheres com IUE sem deficiência esfincteriana detectada ao estudo urodinâmico e que realizavam a correta contração dos MAP. Foram excluídas mulheres com doenças neuromusculares e com prolapso genital graus III e IV. Foram randomizadas 40 mulheres em Grupo Controle e Grupo BF. O protocolo de TMAP com equipamento de BF foi constituído de três séries de dez contrações lentas (tônicas), com tempo de manutenção de seis a oito segundos em cada contração, seguido de um período de repouso de mesmo valor. Após cada contração sustentada, eram realizadas de três a quatro contrações rápidas (fásicas) em decúbito dorsal e ortostatismo, duas vezes na semana, totalizando 12 sessões. Avaliou-se o efeito da adição do BF ao TMAP na qualidade de vida pelo King's Health Questionnaire (KHQ), nos sintomas urinários pelo diário miccional e na função dos músculos do assoalho pélvico (MAP) pela palpação digital. A avaliação foi realizada inicialmente e após as 12 sessões de tratamento. O resultado foi descrito em médias e desvios padrão. Para análise de homogeneidade e verificação das diferenças entre os grupos utilizou-se o teste de Mann-Whitney, e para diferenças entre os momentos de observação, o teste de Wilcoxon, com nível de significância de 0,05. RESULTADOS: Diminuição significativa nos escores dos domínios avaliados pelo KHQ na comparação entre os grupos, exceto para o domínio saúde geral (Grupo BF 32,8±26,9 versus Grupo Controle 48,4±29,5; p<0,13). Em concordância, observou-se melhora da função dos MAP após o tratamento no grupo BF, na power (4,3±0,8; p=0,001), endurance (6,0±2,2; p<0,001) e fast (9,3±1,9; p=0,001). Quando comparados os grupos, o Grupo BF destacou-se positivamente em relação ao power (Grupo BF 4,3±0,8 versus Grupo Controle 2,5±0,9; p<0,001), endurance (Grupo BF 6,0±2,2 versus Grupo Controle 2,7±1,9; p<0,001) e fast (Grupo BF 9,3±1,9 versus Grupo Controle 4,6±3,2; p<0,001). Redução da frequência urinária noturna (1,2±1,2 versus 0,7±0,9; p=0,02) e da perda de urina nos esforços (1,5±1,4 versus 0,6±0,8; p=0,001) foi observada no Grupo BF. CONCLUSÃO: A adição do BF ao TMAP para o tratamento da IUE, aplicado de acordo com o protocolo descrito, contribui para melhora da função dos MAP, redução dos sintomas urinários e melhora da qualidade de vida.

To evaluate the impact of pelvic floor muscle (PFM) training on the quality of life (QOL) in women with stress urinary incontinence (SUI). Prospective clinical trial with 36 women with a diagnosis of SUI confirmed by urodynamic study. Women with neuromuscular diseases, using hormone replacement therapy, and with prolapse stage III and IV were not included. The exercise protocol for the PFM consisted of slow contractions (tonic fibers), followed by rapid contractions (phasic fibers) practiced in the supine, sitting, and standing positions, three times a week for a period of three months. We evaluated the impact of PFM on QOL using the King's Health Questionnaire (KHQ), a voiding diary, and digital palpation to assess the function of the PFMs during the initial evaluation and after three months of treatment. The result was described as means and standard deviations. We used the Wilcoxon test for comparison of the KHQ scores for paired samples, and the significance level was set at 0.05. There was a significant decrease in the mean scores of the domains assessed by the KHQ regarding the perception of health, impact of the incontinence, limitations of daily activities, physical limitations, social limitations, personal relationships, emotions, sleep/disposition, and measures of severity. In agreement with these results, significant decrease in nocturnal urinary frequency and urinary incontinence, as well as significant increase in muscle strength and endurance were observed. PFM training resulted in significant improvement in the QOL of women with SUI.

Aims: The abdominal hypopressive technique (AHT) is performed mainly via transversus abdominis (TrA) activation and has been indicated for pelvic floor muscle (PFM) disorders. In some European countries, this technique has become widely used. This study aimed to investigate PFM and TrA activation during the AHT through surface electromyography.Methods: Thirty‐four nulliparous physical therapists in good general health were asked to participate in the trial. To ascertain a correct PFM contraction, each of the participants was assessed by inspection and digital palpation. Ability to contract the TrA was assessed by surface electromyography and AHT training was given before analysis. TrA and PFM activity was recorded using surface electromyography.Results: The mean age of the volunteers was 28.1 (±6.0) years and the mean body mass index was 23.7 (±3.3) kg/m². More than half of the volunteers were physically active (61.3%) and regularly performed PFM training (52.9%) but not TrA exercises (58.8%). Although the AHT activates the PFM when compared to resting tone (P < 0.001), this method is significantly less effective than PFM alone (P < 0.001). Additionally, the combination of the two techniques (AHT + PFM) was similarly effective as isolated PFM contraction (P = 0.586). Although the AHT activated the TrA significantly more than did PFM alone (P = 0.002), the addition of PFM contraction to the AHT significantly increased the amount of TrA activation (P < 0.001).Conclusions: Based on our results, the AHT is less effective than PFM contraction alone, and adding PFM contraction to AHT also improves the TrA contraction.

This pilot study aimed to investigate the effectiveness of pelvic floor muscle training (PFMT) for the treatment of pelvic organ prolapse. Thirty-seven women with stage II prolapse were randomized to either the intervention group (n = 21) or the control group (n = 16). The evaluation included assessments of pelvic floor muscle function and surface electromyography at baseline and post 14 weeks of treatment. The severity of prolapse was quantified by the POP-Q method and symptoms by P-QoL questionnaire. The intervention group showed significantly greater anatomic improvements in the anterior and posterior vaginal wall prolapses than did the control group (P < 0.001 and 0.025, respectively) and a decrease of symptoms. In addition, the intervention group had greater improvements in muscle strength (P < 0.001), endurance (P < 0.001), and electromyography parameters (P = 0.008) compared to the control group. PFMT is effective in the treatment of pelvic organ prolapse.
