A randomized trial comparing vaginal laser therapy and pelvic floor physical therapy for treating women with stress urinary incontinence.

INTRODUCTION: Female stress urinary incontinence (SUI) is considered a major public health issue. Physical therapy is an important conservative treatment; however, it is primarily limited by poor long-term compliance. Furthermore, surgical treatment entails significant risks. Therefore, new treatment techniques must be identified. OBJECTIVE: To compare the use of laser therapy and pelvic floor (PF) physical therapy for treating postmenopausal women with SUI. METHODS: This pilot study enrolled 40 women with a clinical and urodynamic diagnosis of SUI who were randomized into two groups: those who received erbium-doped yttrium-aluminum-garnet (Er:YAG) laser therapy implemented over three sessions with a 1-month interval (n = 20) and those who received physical therapy with supervision twice a week for 3 months (n = 20). In total, 16 women completed the treatment in each group. The patients were assessed for PF function using the modified Oxford scale and for pelvic organ prolapse using the Pelvic Organ Prolapse Quantification System. The 1-h pad test and quality of life questionnaires, King's Health Questionnaire (KHQ), and Incontinence Quality of Life (IQOL) were also administered. Patients were re-evaluated at 1, 3, 6, and 12 months after treatment. RESULTS: The mean patient age was 62.7 ± 9.1 and 57.9 ± 6.1 years, median Oxford score at baseline was 3 (2-4.5) and 4 (3-4), mean IQOL score was 79.8 ± 17 and 74.6 ± 18 for physical therapy group (PTG) and laser group (LG), respectively. For the amount of urine leak in the 1-h pad test evaluation, we found significance for the interaction of group and time points only for the Laser intragroup. The cure rate, that is, the rate of reaching an insignificant score in the pad test, at 6 and 12 months was 43.75% and 50% in PTG and 62.5% and 56.25% in the LG, respectively (p > 0.05). IQOL scores demonstrated considerable improvement in both groups (p > 0.05). Upon comparing the initial and follow-up results, the LG showed an improvement at all consultations, whereas the PTG showed improvements at 1, 3, and 6 months but not at 12 months after treatment. KHQ analysis revealed a considerable improvement in the quality of life (QOL) of patients over time, with no substantial difference between the groups. QOL comparison before and after treatment revealed that the vaginal LG improved more consistently in some domains. Only the PTG showed a significant increase in the mean Oxford score from pretreatment to 1 and 3 months after treatment (p < 0.001 and p = 0.002, respectively). However, no statistically significant difference was observed between the groups. CONCLUSION: Both treatments are safe and have a positive influence on the impact of UI on patients' QOL. The laser caused a greater reduction in the urinary loss, as measured using the weight of pad test, at 6-month and 12-month after treatment without difference with PTG at the end of the follow-up.

Effect of Pelvic Floor and Hip Muscle Strengthening in the Treatment of Stress Urinary Incontinence: A Randomized Clinical Trial.

OBJECTIVE: To investigate the effectiveness of strengthening the hip muscles in addition to strengthening the pelvic floor muscles (PFM) in the treatment of stress urinary incontinence. METHODS: This study used a prospective, assessor-blind, randomized clinical trial with parallel groups. We randomly allocated 47 individuals with stress urinary incontinence to 2 groups: 1 performing only pelvic floor strengthening exercises (PF, n = 21) and the other performing pelvic floor strengthening exercises plus exercises for the gluteus maximus and medius and hip adductor muscles (PFH, n = 22). Four individuals did not complete the study. Frequency of urine leakage was the primary outcome (3-day voiding diary and a follow-up voiding diary). Secondary outcomes were pelvic floor muscle strength (Ortiz scale, PERFECT scheme [Oxford Scale], and perineometry) and quality of life (QoL; International Consultation on Incontinence Questionnaire-Short Form and King's Health Questionnaire), which were evaluated by a blinded assessor before and after 20 sessions over 10 weeks. RESULTS: Regarding the daily frequency of urine loss evaluated by the follow-up voiding diary, an effect of group was observed (P < .001), with the PFH group showing a significant decrease in daily loss frequency, although no significant differences were found in the comparison between groups for the 3-day voiding diary, QoL, or functional assessment of the PFM. CONCLUSION: Strengthening the PFM together with the hip synergic muscles showed better results for frequency of daily urine loss throughout the sessions, although there was no accompanying superiority in improvement of strength, perineometry, or QoL over the group that performed only PFM-strengthening exercises.

Quantitative assessment of postural alignment in young adults based on photographs of anterior, posterior, and lateral views.

OBJECTIVE: Postural assessment through photography is a simple method that allows the acquisition of quantitative values to define the alignment of body segments. The purpose of this study was to quantitatively assess the postural alignment of several body segments in standing through anterior, posterior, and lateral views. METHODS: In this cross-sectional study, 122 subjects were initially evaluated. Seven subjects were excluded from the study after cluster analysis. The final sample had 115 subjects, 75% women with a mean age of 26 ± 7 years. Photographs were taken from anterior, posterior, and lateral views after placement of markers on specific anatomical points. Photographs were analyzed using free Postural Analysis Software/Software of Postural Analysis (PAS/SAPO). Quantitative values for postural analysis variables were ascertained for head, upper and lower limbs, and trunk, along with the frequency of inclinations to the left and to the right. RESULTS: Regarding the head, 88% of the sample presented some inclination, 67% of which was to the right. There was a predominance of right inclination of the shoulder and pelvis in 68% and 43% of study subjects, respectively. Lower limbs presented mean alignment of 178° in the anterior view, and the trunk showed predominant right inclination in 66% of participants. CONCLUSION: Small asymmetries were observed in anterior and posterior views. This study suggests that there is no symmetry in postural alignment and that small asymmetries represent the normative standard for posture in standing.

Quality of life and discriminating power of two questionnaires in fibromyalgia patients: Fibromyalgia Impact Questionnaire and Medical Outcomes Study 36-Item Short-Form Health Survey.

BACKGROUND: Fibromyalgia is a painful syndrome characterized by widespread chronic pain and associated symptoms with a negative impact on quality of life. OBJECTIVES: Considering the subjectivity of quality of life measurements, the aim of this study was to verify the discriminating power of two quality of life questionnaires in patients with fibromyalgia: the generic Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36) and the specific Fibromyalgia Impact Questionnaire (FIQ). METHODS: A cross-sectional study was conducted on 150 participants divided into Fibromyalgia Group (FG) and Control Group (CG) (n=75 in each group). The participants were evaluated using the SF-36 and the FIQ. The data were analyzed by the Student t-test (α=0.05) and inferential analysis using the Receiver Operating Characteristics (ROC) Curve--sensitivity, specificity and area under the curve (AUC). The significance level was 0.05. RESULTS: The sample was similar for age (CG: 47.8 ± 8.1; FG: 47.0 ± 7.7 years). A significant difference was observed in quality of life assessment in all aspects of both questionnaires (p<0.05). Higher sensibility, specificity and AUC were obtained by the FIQ (96%, 96%, 0.985, respectively), followed by the SF-36 (88%, 89% and 0.948 AUC). CONCLUSION: The FIQ presented the highest sensibility, specificity and AUC showing the most discriminating power. However the SF-36 is also a good instrument to assess quality of life in fibromyalgia patients, and we suggest that both should be used in parallel because they evaluate relevant and complementary aspects of quality of life.

CONTEXTUALIZAÇÃO: A fibromialgia é uma síndrome dolorosa caracterizada por dor espalhada e crônica e sintomas associados com um impacto negativo na qualidade de vida. OBJETIVOS: Considerando a subjetividade da mensuração de qualidade de vida, o objetivo deste estudo foi avaliar o poder de discriminação de dois questionários que avaliam a qualidade de vida de pacientes com fibromialgia: o genérico Medical Short Form Healthy Survey (SF-36) e o específico Questionário do Impacto da Fibromialgia (QIF). MÉTODOS: Foi conduzido um estudo transversal com 150 indivíduos, divididos em dois grupos: grupo fibromialgia (FM) e grupo controle (GC) (n=75 em ambos). Os pacientes foram avaliados pelo SF-36 e pelo QIF. Na análise dos dados, utilizou-se o teste "t de Student" com α=0,05 e a Curva ROC (Receiver Operating Characteristics Curve). RESULTADOS: As amostras foram estatisticamente semelhantes para a idade - 47,8 (8,1) no GC e 47,0 (7,7) no FM - e estatisticamente diferentes em todos os aspectos dos dois questionários (SF-36 e QIF). Alta sensibilidade, especificidade e área abaixo da curva (AUC) foram obtidas com o QIF (96 por cento, 96 por cento, 0,985 respectivamente), seguido pelo SF-36 (88 por cento, 89 por cento e 0,948 AUC). CONCLUSÃO: O QIF mostrou-se mais discriminativo do que o SF-36 para avaliar a qualidade de vida de fibromiálgicos. No entanto, o SF-36 é também um bom instrumento de avaliação e sugere-se que ambos sejam usados uma vez que avaliam aspectos relevantes e complementares da qualidade de vida.
