Effects of different resistance training programmings on the relative strength, body composition, anthropometric variables, and metabolic risk of elderly women.

The purpose of this study was to analyze the effect of two different programming models of resistance training (RT) on metabolic risk, anthropometric variables, and relative strength in elderly women. The research was a prospective and comparative longitudinal study with a non-probabilistic random sample. Twenty-two elderly women (64 ± 3 years) was divided into two experimental groups being the Linear programming (LP, n = 12) and Daily undulatory programming (DUP, n = 10), with 3 sessions/week for 12 weeks. Submaximal strength (10RM) was evaluated in the horizontal leg press (HL), pulldown (PD), leg curl (LC), vertical bench press (BP), and leg extension (LE). Anthropometric variables, food intake (R24h) and submaximal strength (10RM) was analyzed. Participants were initially classified as overweight or obese evaluated by body mass index (BMI) and percentual of fat mass (%FM) and with moderate to high risk to develop metabolic diseases evaluated by hip-waist ratio (HWR), waist-height ratio (WHR) and waist circumference (WC). There is no change for metabolic risk and anthropometric variables after the intervention period. There was a significant improvement for relative strength accessed by 10RM and body weight (10RM/BW), and lean body mass (10RM/LBM) (p < 0.05), with large or medium effect size for most of variables after 12 weeks of RT. As a conclusion, both programmings increased relative strength after 12 weeks of RT with attenuated change in body composition and metabolic risk in elderly women in both programming groups and all those strategies can be used in elderly women to improve strength.

Anterior Knee Pain Scale (AKPS): structural and criterion validity in Brazilian population with patellofemoral pain.

PURPOSE: To identify the best internal structure of the Brazilian version of the Anterior Knee Pain Scale (AKPS), comparing different instrument structures (structural validity) and correlating the scores of the versions (criterion validity). METHODS: We included Brazilian volunteers, aged ≥ 18 years, with patellofemoral pain (PFP) for at least 3 months. We used the confirmatory factor analysis and considered the following fit indices: chi-square/degrees of freedom (DF), comparative fit index (CFI), Tucker-Lewis index (TLI), root mean square error of approximation (RMSEA). We considered the structure with the lowest values of the Akaike information criterion (AIC), sample size adjusted Bayesian information criterion (SABIC), and assessed criterion validity using Pearson correlation coefficient (r) to correlate the long and short versions. RESULTS: The study included 101 participants, mostly women (65.3%), young adults (~ 31 years old), overweight (BMI > 25 kg/m2), incomplete higher education (37.6%), and physically active (64.4%). The original 1-domain, 13-item structure showed adequate fit indices (chi-square/GL < 3.00, TLI and CFI > 0.90, and RMSEA < 0, 08). However, items 11 and 12 had a factorial load of less than 0.23. Therefore, we excluded items 11 and 12 and found adequate fit indices (chi-square/GL < 3.00, TLI and CFI > 0.90, and RMSEA < 0, 08) and lower AIC and SABIC values. We observed a correlation coefficient above the acceptable cutoff of 0.70 (r = 0.966, p-value < 0.001) between the versions. CONCLUSION: The 11-item AKPS (without items 11 and 12) is the version with the most adequate internal structure and correlates satisfactorily with the long version of the instrument.

Reliability of the Heart Rate Variability Registered Through Polar Cardio Frequency Meter in Individuals With Chronic Low Back Pain.

Objective: The purpose of this study was to analyze the intra- and inter-examiner reliability of the analysis of heart rate variability (HRV) captured by a Polar cardio frequency meter in individuals with chronic nonspecific low back pain. Methods: The study included 35 individuals with nonspecific low back pain, both sexes, aged 18 to 45. We used a Polar V800 cardio frequency meter to capture HRV in individuals in different positions, and we calculated the reliability through the intraclass correlation coefficient (ICC). Results: Regarding intra-examiner reliability, we found excellent reliability of HRV analysis in the supine position (ICC ranging from 0.89 to 1.00) and in the standing position (ICC ranging from 0.95 to 0.99). In addition, for inter-examiner reliability, we found substantial to excellent reliability of the HRV analysis in the supine position (ICC ranging from 0.76 to 0.98) and moderate to excellent reliability in the standing position (ICC ranging from 0.73 to 0.99). Conclusion: The HRV analysis captured by a Polar cardio frequency meter presented adequate reliability when considering different times and different examiners.

15-item Roland-Morris disability questionnaire for general pain (RMDQ-g): Structural validity and criterion validity on Brazilian patients with chronic pain.

BACKGROUND: Roland-Morris Disability Questionnaire for general pain (RMDQ-g) is an instrument adapted to assess disability in patients with pain in any region of the body. OBJECTIVE: To perform the structural and criterion validity of the RMDQ-g in Brazilian patients with chronic pain. DESIGN: A cross-sectional study. METHODS: We included native speakers of Brazilian Portuguese, of both sexes, aged ≥18 years, with pain for at least 3 months in any region of the body. Participants eligible for the study responded to an online form containing personal and clinical data, and assessment instruments. We used the confirmatory factor analysis and considered the following fit indices: chi-square/degree of freedom (DF), comparative fit index (CFI), Tucker-Lewis index (TLI), root mean square error of approximation (RMSEA). In the comparison between models, we considered the structure with the lowest values of the Akaike information criterion (AIC) and sample-size adjusted Bayesian information criterion (SABIC). We assessed criterion validity via Spearman's correlation coefficient (rho) to correlate the long and short versions. RESULTS: The study consisted of 297 participants with chronic pain. The main sites of pain were the lumbar region (40.7%), thoracic (21.5%), and neck (19.5%). Mean pain intensity was greater than 5 points. The 24-item long version and the 15-item short version had adequate fit indices (chi-square/DF ≤ 1.77, CFI ≥0.97, TLI ≥0.96, and RMSEA ≤0.05). However, when comparing structures, the short version was the most appropriate because it had the lowest values of AIC (2562.05) and SABIC (2577.72). Criterion validity was acceptable (rho = 0.94) and internal consistency as well (Cronbach's alpha = 0.87). CONCLUSION: The structural validity and criterion validity of the RMDQ-g with one domain and 15 items is the most appropriate version and should be considered in the clinical environment and in research for measuring disability in patients with chronic pain in any region of the body.

Linear and undulating resistance training programming induce similar outcomes on physical fitness in elderly women / Programações linear e ondulatória do treinamento de força induzem a mesmos resultados na aptidão física em mulheres idosas

Abstract The aim of the present study was to analyze the effect of two different types of resistance training programming (linear and daily undulating) on submaximal strength and functional capacity in elderly women. Twenty-two participants (64 ± 3 years) were randomly assigned to 2 training groups: linear programming (LP; n=12) and daily undulating programming (DUP; n =10). Functional capacity and submaximal strength (10RM) were analyzed before and after 12 weeks of resistance training. The results demonstrated improvement on strength and functional capacity after the resistance training period (p ≤ 0.05), except for the Bench Press (p = 0.30), for both groups DUP and LP. The Effect Size was, respectively, high for DUP (timed up and go test = -2.07, and timed sit test= 4.69), and high for LP (horizontal leg press = 2.35). For all other results, the effect size was trivial or small. No statistical difference was observed between programming models. The LP and DUP trainnings have similar results in increasing submaximal muscle strength in elderly women inexperienced in RT after 12 weeks of intervention (p ≤ 0,05). However, DUP appears to be more effective in increasing functional capacity. In practice, the professional can use both the LP and the DUP to improve the level of fitness in the early stages of training in this population. However, when the goal of programming is to increase functional capacity, DUP can be prioritized.

Resumo O objetivo do presente estudo foi analisar o efeito de dois tipos diferentes de programação do treinamento de força (linear e ondulatório diário) na força submáxima e na capacidade funcional de mulheres idosas. Vinte e duas participantes (64 ± 3 anos) foram randomizados em 2 grupos experimentais: programação linear (PL; n=12) e programação ondulatória diária (POD; n=10). A capacidade funcional e a força submáxima (10RM) foram avaliadas antes e depois das 12 semanas de treinamento de força. Os resultados demonstraram melhora da força submáxima e da capacidade funcional após o período de treinamento (p ≤ 0,05), exceto para o exercício supino (p = 0,30), para ambos os grupos POD e PL. Foi encontrado um tamanho de efeito grande para a POD nos testes de sentar e caminhar = -2,07 e teste de sentar e levantar = 4,69, bem como na PL para o exercício leg press horizontal = 2,35. Não foi observada diferença estatística entre os modelos de programação. As programações LP e DUP têm resultados semelhantes no aumento da força muscular submáxima em mulheres idosas inexperientes em TR após 12 semanas de intervenção (p ≤ 0,05). No entanto, o DUP parece ser mais eficaz para aumentar a capacidade funcional. Na prática, o profissional pode usar tanto o LP quanto o DUP para melhorar o nível de condicionamento físico nos estágios iniciais do treinamento nessa população. Porém, quando o objetivo da programação é aumentar a capacidade funcional, o DUP pode ser priorizado.

Comparison of the autonomic nervous system dysfunction between different chronic spine disorders: neck pain versus low back pain.

OBJECTIVE: This study aims to compare heart rate variability (HRV) between patients with chronic neck pain and patients with chronic low back pain and to correlate the chronic pain variables with heart rate variability indices. METHODS: This is a cross-sectional study. We divided the sample into two groups: neck pain (n=30) and low back pain (n=30). We used the Numeric Pain Rating Scale, Neck Disability Index, Roland-Morris Disability Questionnaire, Pain-Related Catastrophizing Thoughts Scale, Tampa Scale of Kinesiophobia, and Pain Self-Efficacy Questionnaire. For heart rate variability analysis, we used the following indices: mean RR, standard deviation of all RR intervals, mean heart rate, root mean square differences of successive RR intervals, triangular index, triangular interpolation of the interval histogram, low-frequency band in arbitrary units and in absolute values, high-frequency band in arbitrary units and in absolute values, standard deviation of the instantaneous beat-to-beat variability (standard deviation 1), long-term standard deviation of continuous RR intervals (standard deviation 2), and Stress Index. We used Student's t-test for comparisons and Spearman's coefficient for correlations. RESULTS: We observe insignificant values in the differences between the groups. Disability and self-efficacy were correlated with heart rate variability only in patients with chronic neck pain, whereas catastrophizing and kinesiophobia showed greater correlations with heart rate variability in patients with chronic low back pain. CONCLUSIONS: Autonomic dysfunction of individuals with chronic neck pain, when compared to patients with chronic low back pain, does present insignificant differences.

Cardiac autonomic modulation response and functional capacity in older women / Respuesta de la modulación autonómica cardíaca y capacidad funcional en mujeres mayores / Resposta da modulação autonômica cardíaca e capacidade funcional em mulheres idosas

ABSTRACT Objective: To analyze cardiac autonomic modulation response and functional capacity in physically active older women. Methods: Seventy-five older women (60-70 years) from the community were divided into the following groups: sedentary (n=19), hydro-gymnastics (n=18), pilates (n=19), and dance (n=19). Blood pressure, body composition, heart rate variability, and functional capacity were assessed for the characterization of the groups at rest and 48 hours after the last physical exercise session. Results: The sedentary group presented higher waist-to-hip ratio, diastolic blood pressure, and resting heart rate compared to the other groups (p<0.05). It was also observed that the dance group presented better functional capacity and VO2peak scores (all p<0.05). Regarding cardiac autonomic modulation, both dance and pilates groups demonstrated better RMSSD (26.71 ± 9.07 and 29.82 ± 7.16, respectively; p<0.05), LF (45.79 ± 14.81 and 45.95 ± 15.16 n.u., respectively; p<0.05), and LF/HF (0.92 ± 0.56 and 0.58 ± 0.26, respectively; p<0.05) scores. In the symbolic analysis, the dance group had a greater predominance of parasympathetic autonomic modulation than the other groups (p<0.05). Conclusion: These results conclude that physically active elderly women, practicing hydro-gymnastics, pilates or dance, presented physiological benefits, such as better functional capacity and improvements in hemodynamic variables and autonomic cardiac modulation. In addition, the group that practiced dance presented greater parasympathetic modulation, as well as greater functional capacity, when compared to the other modalities. Level of evidence: I; STARD: studies of diagnostic accuracy.

Reliability and Accuracy of 2-Minute Step Test in Active and Sedentary Lean Adults.

OBJECTIVE: The purpose of this study was to evaluate the intrarater and interrater reliability of the 2-minute step test (2MST) in active and sedentary lean adults and to identify the test cutoff point to differentiate active from sedentary individuals. METHODS: This observational study involved 4 mixed-sex groups (each with 50 lean participants): group 1, sedentary and aged 18 to 24 years; group 2, active and aged 18 to 24 years; group 3, sedentary and aged 25 to 44 years; and group 4, active and aged 25 to 44 years. The 2MST was administered independently by 2 examiners (with 3 months' training) at 2 different times, with a 7-day interval. Habitual physical activity was evaluated by means of the Baecke Questionnaire (BQ). In statistical analysis, the Pearson correlation coefficient was used to verify the correlation between the 2MST and BQ; intraclass correlation coefficients (ICC2,3) were used to determine the intrarater and interrater reliability of the 2MST; and the receiver operating characteristic curve was used to identify the accuracy of the 2MST. RESULTS: Excellent intrarater and interrater reliability were found for all 4 groups (intraclass correlation coefficients ≥ 0.83). Correlating the 2MST score with the BQ score, a significant, positive, weak correlation was observed (r = 0.344, P < .001). For differentiating active from sedentary individuals, the 2MST showed low accuracy (area under the curve = 0.671), with 61% sensitivity and 67% specificity. CONCLUSION: This study showed that the 2MST is a reliable test with a low amount of inherent error. There was a significant correlation between the 2MST and usual physical activity measured, and slight accuracy in differentiating active from sedentary individuals.

Acute Effects of Resistance Exercise With Blood Flow Restriction in Elderly Women: A Pilot Study.

AIM: To compare the acute effects of two resistance exercise sessions with different partial blood flow restrictions (BFR) on hemodynamic parameters and cardiac autonomic modulation in older women with metabolic syndrome. METHODS: Thirty-nine older women (64.4 ± 4.5 years) were allocated into three groups: BFR0 = resistance exercise (20%, 1 maximum repetition [MR]) + 0% BFR; BFR60 = 20% 1 MR resistance exercise + 60% BFR; and BFR80 = 20% 1MR resistance exercise + 80% BFR. RESULTS: A reduction of 14 mmHg (BFR60 group) and 13 mmHg (BRF80 group) was observed 48 hr after the first exercise session, while vagal modulation was increased in the BRF60 group after 24 and 48 hr. CONCLUSION: A low-intensity resistance exercise session with 60% and 80% of BFR resulted in blood pressure (systolic, diastolic, and mean) reduction and positive changes on heart rate variability after 24 h of a RE session.

Brazilian Version of the Self-Estimated Functional Inability Because of Pain in Dancers: A Validation Study.

OBJECTIVE: The purpose of this study was to measure the reliability, internal consistency, construct validity, and floor and ceiling effects of the Brazilian version of the Self-Estimated Functional Inability because of Pain (SEFIP-dance) instrument. METHODS: This was a questionnaire validation study. Both professional dancers and those who use dance as a recreational activity were included in the study. For test-retest reliability, SEFIP-dance was administered to the same dancer at 2 different times, with an interval of 7 days between the moments. For construct validity, Spearman's correlation coefficient (r s) was used to determine the magnitude of the correlations between SEFIP-dance and the Numerical Rating Scale, the 36-Item Short-Form Health Survey, the Roland-Morris Disability Questionnaire for general pain, and the Örebro Musculoskeletal Pain Questionnaire. RESULTS: A total of 111 dancers were recruited and included in the study. From this total sample, a subsample of 31 was used for the calculations of test-retest reliability: when considering each item of SEFIP-dance, we observed adequate κ values (κ ≥ 0.52); considering the total score, we observed excellent reliability (intraclass correlation coefficient = 0.94). In addition, we identified adequate values for internal consistency (Cronbach's α ≥ 0.80). We observed significant correlations of the SEFIP-dance total score with the Numerical Rating Scale, 36-Item Short-Form Health Survey, the Roland-Morris questionnaire, and the Örebro Musculoskeletal Pain Questionnaire (r s varying between 0.248 and 0.489). Ceiling and floor effects were not observed. CONCLUSION: This study found that the Brazilian Portuguese version of SEFIP-dance has psychometric properties suitable for its use in dancers.

Seated Single-Arm Shot-Put Test to Measure the Functional Performance of the Upper Limbs in Exercise Practitioners With Chronic Shoulder Pain: A Reliability Study.

OBJECTIVE: To measure the intra- and interrater reliability of the seated single-arm shot-put test (SSPT) in the functional performance of the upper limbs of regular physical exercise practitioners with shoulder pain. METHODS: This is a reliability study. Thirty individuals regularly practicing any sports modality that uses the upper limb effectively for at least 6 months, both sexes, ages between 18 and 30 years, with chronic shoulder pain were included. Chronic shoulder pain was measured by means of the shoulder pain and disability index, numerical rating scale, and catastrophic thoughts about pain scale. Functional performance of the upper limbs was measured by means of SSPT. RESULTS: Excellent intrarater reliability was found, with intraclass correlation coefficient ≥0.93, standard error of the measurement values ≤4.63%, and minimum detectable change values for absolute and normalized score of 45.11 cm and 9.97, respectively. Excellent interrater reliability was found, with intraclass correlation coefficient ≥0.96, standard error of the measurement values ≤3.55%, and minimum detectable change values for absolute and normalized score of 32.29 cm and 7.70, respectively. CONCLUSION: SSPT is a reliable tool for measuring the functional performance of the upper limbs in regular exercise practitioners with chronic shoulder pain.

Brazilian version of the Self-Estimated Functional Inability because of Pain questionnaire for musculoskeletal injuries relating to dance and sport: translation and cross-cultural adaptation.

BACKGROUND: Self-Estimated Functional Inability because of Pain (SEFIP) is a questionnaire specifically designed to measure musculoskeletal pain or discomfort. OBJECTIVE: To perform translation and cross-cultural adaptation of the SEFIP for dancers (SEFIP-dance), for use in Brazilian Portuguese. In addition, as a secondary objective, we adapted the translated version of SEFIP-dance for use among athletes or exercise practitioners (SEFIP-sport). DESIGN AND SETTING: Questionnaire translation and cross-cultural adaptation study conducted at a public university. METHODS: The Brazilian version of the SEFIP-dance questionnaire was developed following the processes of translation (involving two translators with Brazilian Portuguese as their mother tongue and fluency in English), backtranslation (involving two translators with English as their mother tongue and fluency in Brazilian Portuguese), committee review and pre-testing. SEFIP-sport was developed following the processes of content and face validation. RESULTS: SEFIP-dance was applied to 30 dancers, of mean age 22.38 years (standard deviation [SD] = 3.41), among whom 14 were men (46.66%). The participants understood 100% of the SEFIP-dance items and alternatives. SEFIP-sport was applied to 30 athletes or physical exercise practitioners, of mean age 25.09 years (SD = 8.93), among whom 25 were men (86.33%). The participants understood 100% of the -SEFIP-sport items and alternatives. CONCLUSION: The Brazilian Portuguese versions of SEFIP-dance, translated and cross-culturally adapted for dancers, and SEFIP-sport, adapted for athletes or physical exercise practitioners, were shown to have adequate levels of understanding.

Correlation Between Habitual Physical Activity and Central Sensitization, Pain Intensity, Kinesiophobia, Catastrophizing, and the Severity of Myogenous Temporomandibular Disorder.

OBJECTIVE: We sought to correlate habitual physical activity with central sensitization, pain intensity, kinesiophobia, catastrophizing, and the severity of chronic myogenous temporomandibular disorder (TMD). METHODS: This was an observational study. Fifty-five individuals, male and female, aged 18 to 45 years, with pain for at least 3 months (chronic) related to myogenous TMD were included in the study. Myogenous TMD was evaluated by means of the Numerical Rating Scale, Catastrophic Thoughts on Pain Scale, Tampa Scale for Kinesiophobia, Fonseca Anamnestic Index, Central Sensitization Inventory, and habitual physical activity by means of the Baecke Questionnaire (BQ). The Spearman correlation coefficient (r s) was applied to verify the association of the BQ score with the pain variables. RESULTS: No significant correlations (P > .05) were observed in the total or mean BQ scores (both r s = -0.17 to -0.04), nor in the analyses performed on the occupational (r s = -0.03 to 0.14), sport (r s = -0.16 to 0.01), and leisure domains (r s = -0.16 to -0.02). CONCLUSION: Habitual physical activity as measured by the BQ is not associated with pain intensity, catastrophizing, kinesiophobia, central sensitization, or the severity of chronic myogenous TMD.

A potência anaeróbia máxima é uma capacidade física presente nos mais diversos gestos esportivos do futsal. Essas ações são realizadas de forma repetitivas o que exige dos jogadores valores importantes no índice de fadiga a fim de manter o desempenho durante a partida. O estudo objetivou traçar o perfil morfológico e neuromotor de uma equipe de futsal feminino e mensurar a potência anaeróbia máxima e o índice de fadiga conforme as posições de jogo. Participaram 17 atletas, idade de 21,8±4,1 anos, estatura 159±0,07cm e massa corporal 56,2±8,2kg. Foram avaliadas medidas antropométricas, composição corporal, neuromotora e da potência anaeróbia máxima. Os dados foram descritos em (média ± desvio padrão, mínimo, máximo e coeficiente de variação). O teste de Shapiro Wilk foi usado para averiguar a normalidade dos dados através do software Stata 14.0 e adotado um valor de α= 5%. Foi observado um índice de fadiga menor das Alas o que mostra melhor resistência ao esforço comparado às outras posições, porém todas foram classificadas com nível "bom". Na potência anaeróbia máxima houve diferenças nos valores entre as posições, porém todas foram classificadas com nível "fraco". Concluiu-se que existem diferenças na potência máxima entre as jogadoras, porém não foi suficiente para classificá-las em níveis aceitáveis para essa capacidade de acordo com a literatura.Diferentemente do IF, mesmo com diferenças entre as posições, todas apresentaram nível classificado como "bom" de acordo com os estudos....(AU)

The maximum anaerobic power is physical capacity present in the most diverse sports gestures of futsal. These actions are carried out repetitively which demand from the players values important in the index of fatigue in order to maintain performance during the match.The study aimed to trace the morphological profile and neuromotor of a famale futsal team and to measure maximum anaerobic power and fatigue index according to the game positions. There were 17 athletes, age of 21.8±4.1 years, stature 159±0.07cm and body mass 56.2±8.2kg. Anthropometric measurements were performed, body composition, neuromotor and maximum naerobic power. The data were described in (average ± standard deviation, minimum, maximum and coefficient of variation). The test of Shapiro Wilk was used to ascertain the normality of the data through State 14.0 software and adopted a value of α= 5%. A lower fatigue index was observed for the Wings, which shows better resistance to stress compared to other positions, but all were classified as "good". In the maximum anaerobic power there were differences in the values between the positions, but all were classified as "weak". It's concluded that there are differences in the maximum power between the players, but it was not enough to classify according to the literature. Unlike the IF, even with differences betweens positions, all presented a level classified as "good" according to the studies....(AU)

Hypertension and functional capacities in community-dwelling older women: a cross-sectional study.

PURPOSE: The present study aimed to investigate the association between hypertension and physical/functional capacities in community-dwelling older females. MATERIALS AND METHODS: Older female volunteers were dichotomized in two groups: hypertensive (n = 134) and normotensive (n = 244). Volunteers had their medical records reviewed and underwent evaluations of anthropometric data (weight, height and body mass index) and of physical and functional capacities. RESULTS: The results showed that hypertensive older females presented higher values for age, weight, body mass index, and resting diastolic blood pressure than normotensive older females. Normotensive older females showed a higher performance in the one-leg stand test and six-minute walk test compared with hypertensive older females. Age, body mass index, maximal walking speed, performance in the Time Up and Go and six-minute walk test, and diagnosis of diabetes mellitus type II were factors associated with hypertension using the chi-square test. However, the multivariate regression analysis indicated that performance in the six-minute walk test was the only factor associated with hypertension. CONCLUSIONS: The patients with higher scores in the six-minute walk test, which is associated with aerobic capacity, show less odds to have clinical diagnosis of hypertension. However, hypertension was not associated with poor physical and functional capacity.

Efeitos da reeducação postural global em desvios posturais e seus benefícios nos sintomas de incontinência urinária de esforço / Effects of the global postural reeducation on postural changes and symptoms of stress urinary incontinence

Este objetivou avaliar os efeitos do método da Reeducação Postural Global (RPG) sobre as alterações posturais e dos sintomas da incontinência urinária de esforço (IUE), em mulheres menopausadas. Treze pacientes (59,2 ± 8,9 anos de idade) com diagnóstico clínico de IUE foram submetidos à análise urodinâmica, avaliação da função dos músculos do assoalho pélvico (MAP) e avaliação postural, pré e pós programa de RPG. A análise da qualidade de vida também foi obtida pré e pós intervenção com RPG (questionário ICIQ-SF). O tratamento com RPG foi composto por 12 sessões de 30 minutos de duração, frequência semanal de uma vez por semana, com a realização da postura "rã no chão". Em adição, alongamento da musculatura anterior do corpo e assoalho pélvico também foi realizada. Após a intervenção observou-se a diminuição da quantidade e frequência de perda de urina, sendo que a maioria das pacientes reportou episódios diários de perda urinária antes da intervenção. Perdas urinárias menores que uma vez por semana foram reportadas ao final do tratamento. Reduções nos sintomas da IUE foram acompanhadas por melhora da função urinária e aumento da força dos MAP. Ademais, o programa com exercícios de RPG melhorou os índices da avaliação postural, quando dados individuais foram analisados; grande parte das pacientes estudadas melhorou o índice da curvatura cifótica e o alinhamento do quadril após intervenção. Os exercícios de RPG podem ser um meio eficaz para o tratamento dos sintomas da IUE, pois melhora a função contrátil do assoalho pélvico, proporcionalmente a uma melhora na postura da pelve e redução dos sintomas de IUE (AU).

This study aimed to evaluate the global postural reeducation effects on the stress urinary incontinence(SUI)symptoms. Thirteen menopaused women (59.2 ± 8.9 years old) with diagnosis for SUI undertake urodynamic analysis, pelvic floor muscles (PFM) function and postural indexes evaluation pre and post12-sessions GPR program, consisted of 30-min sessions once a week. A life style quality evaluation (questionnaire ICIQ-SF) was further obtained pre and post GPR intervention. The sessions of GPR exercises included "frog on the ground" type-exercises. After GPR intervention there were reductions in the quantity and frequency of urine loss; most patients reported daily episodes of urine loss before the GPR program, however urine loss was lower than once a week at the end of the GPR program. Reductions of the SUI symptoms occurred together with improvements in urinary function and PFM performance. The GPR program improved postural indexes when individual data were analyzed, as several patients improved the kyphosis curvature index and hip alignment. Improvements in UIE symptoms and postural indexes occurred together with an improved life style quality reported by patients. These results suggest that GPR may be an alternative for the SUI treatment in menopaused women (AU).
