Constraint Induced Movement Therapy Increases Functionality and Quality of Life after Stroke.

This blind randomized clinical trial evaluated the effect of CIMT on the functionality and quality of life (QOL) of chronic hemiparetics. Thirty volunteers were divided into two groups: Control (CG) and CIMT (CIMTG); evaluated before and after 12 and 24 intervention sessions. The scales used were: adapted Fugl-Meyer Motor Assessment (FMA), Modified Ashworth, Stroke Specific Quality Of Life (SS-QOL) and the Functional Reach Test (FRT). The scores for all FMA variables in the CIMTG increased until the 24th session, differing from the pre-treatment. In the CG, the scores increased for pain, coordination/ speed and sensitivity. In the FRT there was an increase in the scores in both groups; after the 12th and 24th sessions, the result of the CIMTG was superior to the CG. For the SS-QOL in the CIMTG, the general score and most of the variables increased, as well as in the CG. Muscle tone in CIMTG was lower compared to CG after 24 sessions. Both protocols used in the study were effective, the CIMT protocol showed benefits in recovering the functionality of the paretic upper limb, in the functional range and in reducing muscle tone, with a consequent improvement in quality of life.

Impact of physical activity levels on musculoskeletal symptoms and absenteeism of workers of a metallurgical company.

INTRODUCTION: Physical inactivity is the fourth biggest risk factor for global mortality. In Brazilian metallurgical industries, workers present a high incidence of musculoskeletal symptoms as one of the main causes of absenteeism. OBJECTIVES: To investigate the impact of physical activity levels and leisure-time physical exercise on musculoskeletal symptoms and absenteeism among administrative and production workers of a metallurgical industry. METHODS: This is a transversal study that included 206 workers. We applied the Modified Baecke Questionnaire, leisure-time physical activity and leisure-time physical exercise domains), as well as the Nordic Musculoskeletal Questionnaire regarding symptom occurrence and severity scores (1-4), and compared levels of absenteeism. Our sample was divided into 2 groups: production and office workers. RESULTS: We observed a significant difference between the groups regarding symptom severity score 3 (p = 0.03) and absenteeism (p = 0.02); the production group presented higher results. There was a correlation between leisure-time physical exercise and absenteeism (r = -0.57, p = 0.01) and between leisure-time physical activity and absenteeism (r = -0.55, p = 0.01) in the production worker group, whereas in the office worker group, leisure-time physical activity and symptom severity score 4 were correlated (r = 0.63, p = 0.02). CONCLUSIONS: Production workers presented higher occurrences of symptom severity score 3 and absenteeism; increased levels of leisure-time physical activity and physical exercise reduced absenteeism. Leisure-time physical activity was correlated with severity score 4 in the office worker group.

The effect of local muscle endurance training on cardiorespiratory capacity in young women.

The purpose of this study was to investigate the effect of local muscle endurance training on maximal oxygen uptake and ventilatory threshold in young women. Nineteen untrained women, ranging in age from 18 to 26 years, were included in the study and assigned to two groups: the control group (n = 10), and the resistance training group (n = 9). The following variables were obtained at baseline and after 12 weeks: body mass; maximal oxygen uptake, maximal heart rate, maximal oxygen pulse, oxygen uptake at the ventilatory threshold, heart rate at the ventilatory threshold, and oxygen pulse at the ventilatory threshold assessed by cardiopulmonary exercise testing on treadmill; 1-repetition maximum (RM) tests in bench press, latissimus pull down, military press, lying barbell extension, standing barbell curls, leg press, knee extension, and hamstring curl. The training group underwent resistance strength training. Loading during training followed the concept of maximum repetitions. Each session was defined as the performance of three sets of 15RM with a 60-second rest between sets and exercises. No significant changes were observed in the control group before and after 12 weeks (p > 0.05). All 1RM tests increased after training (p < or = 0.01) in the training group, but no significant change was observed in body mass (p > 0.05). Cardiopulmonary variables showed no significant differences before and after resistance training (p > 0.05). These findings indicate that the local muscle endurance training realized produces no improvement in cardiorespiratory capacity in young women.

AIRWAY POSITIVE PRESSURE VS. EXERCISES WITH INSPIRATORY LOADING FOCUSED ON PULMONARY AND RESPIRATORY MUSCULAR FUNCTIONS IN THE POSTOPERATIVE PERIOD OF BARIATRIC SURGERY.

BACKGROUND: Bariatric surgery can trigger postoperative pulmonary complications due to factors inherent to the procedure, mainly due to diaphragmatic dysfunction. AIM: To evaluate and compare the effects of two levels of positive pressure and exercises with inspiratory load on lung function, inspiratory muscle strength and respiratory muscle resistance, and the prevalence of atelectasis after gastroplasty. METHODS: Clinical, randomized and blind trial, with subjects submitted to bariatric surgery, allocated to two groups: positive pressure group, who received positive pressure at two levels during one hour and conventional respiratory physiotherapy and inspiratory load group, who performed exercises with load linear inspiratory pressure, six sets of 15 repetitions, in addition to conventional respiratory physiotherapy, both of which were applied twice in the immediate postoperative period and three times a day on the first postoperative day. Spirometry was performed for pulmonary function analysis, nasal inspiratory pressure for inspiratory muscle strength and incremental test of respiratory muscle resistance for sustained maximal inspiratory pressure, both preoperatively and on hospital discharge on the second postoperative day. RESULTS: There was no significant difference (p> 0.05) in the expiratory reserve volume and in the tidal volume in the pre and postoperative periods when compared intra and intergroup. There was no significant difference (p>0.05) in the nasal inspiratory pressure and the maximal inspiratory pressure maintained in the inspiratory load group in the intragroup evaluation, but with a significant difference (p<0.05) compared to the positive pressure group. The prevalence of atelectasis was 5% in both groups with no significant difference (p>0.05) between them. CONCLUSION: Both groups, associated with conventional respiratory physiotherapy, preserved expiratory reserve volume and tidal volume and had a low atelectasis rate. The inspiratory loading group still maintained inspiratory muscle strength and resistance of respiratory muscles.

[Use of positive pressure in pre and intraoperative of bariatric surgery and its effect on the time of extubation]. / Utilização da pressão positiva no pré e no intraoperatório de cirurgia bariátrica e seus efeitos sobre o tempo de extubação.

BACKGROUND AND OBJECTIVE: to investigate the influence of intraoperative and preoperative airway positive pressure in the time of extubation in patients undergoing bariatric surgery. METHOD: Randomized clinical trial, in which 40 individuals with a body mass index between 40 and 55kg/m(2), age between 25 and 55 years, nonsmokers, underwent bariatric surgery type Roux-en-Y gastric bypass by laparotomy and with normal preoperative pulmonary function were randomized into the following groups: G-pre (n = 10): individuals who received treatment with noninvasive positive pressure before surgery for one hour, G-intra (n = 10): individuals who received positive end-expiratory pressure of 10cm H2O throughout the surgical procedure and G-control (n = 20): not received any pre or intraoperative intervention. Following were recorded: time between induction of anesthesia and extubation, between the end of anesthesia and extubation, duration of mechanical ventilation, and time between extubation and discharge from the Post-Anesthetic Recovery. RESULTS: there was no statistical difference between groups. However, when applied to the Cohen coefficient, the use of positive end-expiratory pressure of 10cm H2O during surgery showed a large effect on the time between the end of anesthesia and extubation. About this same time, the treatment performed preoperatively showed moderate effect. CONCLUSION: The use of positive end-expiratory pressure of 10cm H2O in the intraoperative and positive pressure preoperatively, influenced the time of extubation of patients undergoing bariatric surgery.

Inspiratory loading exercises on respiratory muscle function in post-operative gastroplasty patients: a randomized clinical trial / Exercícios com carga inspiratória na função muscular respiratória no pós-operatório de gastroplastia: um ensaio clínico randomizado / Ejercicios con carga inspiratoria en la función muscular respiratoria en el postoperatorio de gastroplastia: un ensayo clínico aleatorizado

Abstract Introduction: The gastroplasty post-operative period can alter respiratory mechanics and predispose patients to respiratory complications. Objective: The objective was to evaluate the effects of exercises with inspiratory load on respiratory muscle function and on the prevalence of atelectasis after gastroplasty. Method: 40 participants were randomly allocated into two groups: Control Group (CG), its members underwent conventional respiratory physical therapy (CRP) and the Inspiratory Load Group (ILG), its members performed exercises with linear inspiratory pressure load, with 40% of the maximum inspiratory pressure (MIP), associated with CRP. Therapy procedures were conducted twice during the immediate post-operative period and thrice on the first post-operative day. In addition to evaluating the MIP, the nasal inspiratory pressure (NIP) and the sustained maximum inspiratory pressure (SMIP) were evaluated before and after treatment. Analysis of variance followed by the Bonferroni correction were applied considering a 5% significance level (p < 0.05). Results: There was no significant difference in NIP and SMIP values when the pre- and post-operative periods were compared for the ILG; however, these values were significantly lower for the CG, also with intergroup differences in NIP values. Atelectasis prevalence was 5% for ILG and 15% for CG, with no intergroup difference. Conclusion: The inspiratory muscle strength and resistance of the respiratory muscles were maintained in the group that performed exercises with inspiratory load associated with CRP, with a low rate of atelectasis after gastroplasty.

There was no significant difference (p>0.05) in the nasal inspiratory pressure and the maximal inspiratory pressure maintained in the inspiratory load group in the intragroup evaluation, but with a significant difference (p<0.05) compared to the positive pressure group. The prevalence of atelectasis was 5% in both groups with no significant difference (p>0.05) between them. Conclusion: Both groups, associated with conventional respiratory physiotherapy, preserved expiratory reserve volume and tidal volume and had a low atelectasis rate. The inspiratory loading group still maintained inspiratory muscle strength and resistance of respiratory muscles.

RESUMO Racional : A cirurgia bariátrica pode desencadear complicações pulmonares no pós-operatório devido a fatores inerentes ao procedimento, sobretudo pela disfunção diafragmática. Objetivo : Avaliar e comparar os efeitos da aplicação de dois níveis de pressão positiva e dos exercícios com carga inspiratória na função pulmonar, força muscular inspiratória e resistência muscular respiratória e na prevalência de atelectasia após gastroplastia. Métodos : Ensaio clínico, randomizado e cego, com sujeitos submetidos à cirurgia bariátrica, alocados em dois grupos: grupo pressão positiva, que recebeu pressão positiva em dois níveis, durante uma hora e fisioterapia respiratória convencional e grupo carga inspiratória, que realizou exercícios com carga linear pressórica inspiratória, seis séries de 15 repetições, além da fisioterapia respiratória convencional, sendo ambos aplicados duas vezes no pós-operatório imediato e três vezes ao dia no primeiro dia de pós-operatório. Foram realizados espirometria para análise da função pulmonar, pressão inspiratória nasal para força muscular inspiratória e teste incremental de resistência muscular respiratória para pressão inspiratória máxima sustentada, no pré-operatório e no dia da alta hospitalar, no segundo dia de pós-operatório. Resultados : Não houve diferença significativa (p>0,05) no volume de reserva expiratório e no volume corrente no pré e no pós-operatório quando comparados intra e intergrupo. Não houve diferença significativa (p>0,05) na pressão inspiratória nasal e na pressão inspiratória máxima sustentada no grupo carga inspiratória na avaliação intragrupo, mas com diferença significativa (p<0,05) comparada ao grupo pressão positiva. A prevalência de atelectasias foi de 5% em ambos os grupos sem diferença significativa (p>0,05) entre eles. Conclusão : Ambos os grupos, associados à fisioterapia respiratória convencional, preservaram o volume de reserva expiratório e o volume corrente e apresentaram baixo índice de atelectasias. O grupo carga inspiratória ainda manteve a força muscular inspiratória e a resistência dos músculos respiratórios.

Immediate and lasting improvements in weight distribution seen in baropodometry following a high-velocity, low-amplitude thrust manipulation of the sacroiliac joint.

The biomechanics of the sacroiliac joint makes the pelvic segment responsible for proper weight distribution between lower extremities; however, it is known to be susceptible to altered mobility. The objective of this study was to analyze baropodometric responses following thrust manipulation on subjects with sacroiliac joint restrictions. Twenty asymptomatic subjects were submitted to computerized baropodometric analysis before, after, and seven days following sacroiliac manipulation. The variables peak pressure and contact area were obtained at each of these periods as the average of absolute values of the difference between the right and left foot based on three trials. Data revealed significant reduction only in peak pressure immediately after manipulation and at follow-up when compared to pre-manipulative values (p < 0.05). Strong correlation was found between the dominant foot and the foot with greater contact area (r = 0.978), as well as between the side of joint restriction and the foot with greater contact area (r = 0.884). Weak correlation was observed between the dominant foot and the foot with greater peak pressure (r = 0.501), as well as between the side of joint restriction and the foot with greater peak pressure (r = 0.694). The results suggest that sacroiliac joint manipulation can influence peak pressure distribution between feet, but contact area does not seem to be related to the biomechanical aspects addressed in this study.

New reference values for maximal respiratory pressures in the Brazilian population.

OBJECTIVE: To compare MIP and MEP determined in healthy subjects with those predicted using the equations proposed in another study, and, if necessary, to suggest new equations for MIP and MEP to be used in the Brazilian population. METHODS: The study sample comprised 60 healthy males and 60 healthy females, 20-80 years of age (20 subjects per ten-year age bracket). Maximal respiratory pressures were determined following a standardized protocol. RESULTS: Regarding MIP, the measured values were significantly lower than those predicted for both males (31%) and females (24%). There were no significant differences between measured and predicted MEP in either gender. We found that age presented the greatest power to predict MIP and MEP in both genders. New equations were proposed. CONCLUSIONS: The previously proposed equations were unable to predict MIP and MEP for all of the subjects in our sample. Therefore, the results of this study can facilitate the prediction of respiratory muscle strength in healthy adult subjects in Brazil. Further studies, involving subjects from different regions of the country, could lead to the development of better tables or equations for maximal respiratory pressures in the Brazilian population.

Aplicou-se o nível de significância de p < 0,05. Resultados: Nas variáveis antropométricas não foram encontradas diferenças significativas entre grupos. Na flexibilidade, foi encontrada diferença significativa na flexão e na extensão de quadril, os grupos G1 e G2 apresentaram maiores valores que o G3, não houve diferença significativa entre G1 e G2, não existindo outras diferenças significativas entre os grupos. Conclusão: Os resultados sugerem que os treinamentos de hidroginástica e combinado proporcionaram melhora na flexão e extensão do quadril das mulheres idosas, sem influência nas outras variáveis estudadas.

With aging there comes a decline in physical fitness, including decreasing flexibility, and the practice of physical activity by older adults is an important factor for maintaining health and physical fitness during the aging process. Objective: To compare the flexibility of elderly women who practice either hydrogymnastics or combination exercise training with those who are not active. Sixty females participated in the study, aged between 60 and 80 years and divided into three groups: 20 subjects who actively practiced hydrogymnastics (G1), 20 subjects who actively practiced combination exercise training (G2), and 20 subjects who were not-active (G3). Methods: The subjects underwent anthropometric measurements consisting of weight, height, waist circumference, and flexibility. Measurements were taken with distance reached in the sit and reach test and the extent of flexion and hip extension by means of a goniometer. The assumptions of normality using the Shapiro-Wilk test for comparison between groups (G1, G2, G3) were checked, the one way ANOVA test, followed by the Tukey post hoc for the data with parametric distribution, and the Friedman test for samples with non-parametric distribution were performed. A significance level of p < 0.05 was assumed. Results: The anthropometric variables revealed no significant differences between groups. In the analysis of flexibility, significant differences were found in hip flexion and extension; the G1 and G2 groups showed greater values than the G3, and there were no significant differences between G1 and G2 nor between groups. Conclusion: The results suggest that hydrogymnastics and combination exercise training provided improvements in flexion and hip extension in elderly women, with no influence on the other variables studied.

Perfil sociodemográfico e ocupacional de trabalhadores com LER/DORT: estudo epidemiológico / Perfi sociodemoggráfico y laboral de los trabajadores con LER/TMOL: estudio epidemiológico / Sociodemographic and occupacional profile of workers with RSI/WRMSD: epidemiological study

Analisou-se o perfil sociodemográfico e ocupacional de trabalhadores com lesões por esforços repetitivos (LER) ou disfunções osteomusculares relacionados ao trabalho (DORT) em Piracicaba, São Paulo, avaliando-se a associação desse perfil com a ocorrência de dor, bem como a associação de risco para LER/DORT. Dados de 1.007 prontuários foram submetidos à análise descritiva (p<0,05). A LER/DORT predominou em mulheres, na idade produtiva, com baixo grau de instrução e baixos salários, com função de doméstica, cozinheira, serviços gerais, auxiliar de produção e costureira; a dor predominou no membro superior e estava associada à função, ao gênero feminino, ao baixo grau de instrução e ao estado civil; houve associação de risco entre organização e ergonomia no trabalho e dor no membro superior. A compreensão das relações do trabalhador com o ambiente de trabalho e com o trabalho pode favorecer medidas de vigilância e promoção de saúde.

The socio-demographic and occupational profile of workers with repetitive strain injury (RSIs) or work-related musculoskeletal disorders (WRMSDs) in Piracicaba, São Paulo, Brazil, were analyzed. The association of this profile with the occurrence of pain as well as the risk association for RSI/WRMSD were evaluated. Data from 1,007 medical records underwent descriptive analysis (p<0.05). RSI/WRMSD was predominant in women in their productive age, with low education level and low wages, working mainly in domestic roles, cook, general services, production assistant and seamstress; pain was predominant in the upper limb and it was associated with the function, the female gender, low education level and marital status; there was risk association between organization and workplace ergonomics and pain in upper limb. The understanding of the relationship between the worker, the work environment, and the work may favor surveillance measures and health promotion.

Lung age in women with morbid obesity / Idade pulmonar em mulheres com obesidade mórbida

OBJECTIVE: To investigate the influence of morbid obesity on the lung age in women and to correlate with body mass, body mass index (BMI), and ventilatory variables. METHODS: This was a cross-sectional study with 72 morbidly obese women and a control group consisting of 37 normal weight women. The subjects performed a pulmonary function test to determine lung age, and the results were correlated to anthropometric variables and lung volumes. RESULTS: The morbidly obese group had significantly higher lung age (50.1 ± 6.8 years) than the control group (38.8 ± 11.4 years). There was no difference in chronological age between groups. There was a significant positive correlation among chronological age, body mass, BMI, and lung age (r = 0.3647, 0.4182, and 0.3743, respectively). There was a negative correlation among forced vital capacity (FVC), forced expiratory volume in one second (FEV1), FEV1/FVC ratio, expiratory reserve volume (ERV), and lung age (r = -0.7565, -0.8769, -0.2723, and -0.2417, respectively). CONCLUSION: Lung age is increased in morbidly obese women and is associated with increased body mass and BMI.

OBJETIVO: Verificar a influência da obesidade mórbida na idade pulmonar de mulheres e correlacionar com a massa corporal, índice de massa corporal (IMC) e variáveis ventilatórias. MÉTODOS: Estudo longitudinal realizado com 72 obesas mórbidas e grupo controle constituído de mulheres eutróficas. As voluntárias realizaram um teste de função pulmonar para determinação da idade pulmonar e os resultados foram correlacionados com as variáveis antropométricas e volumes pulmonares. RESULTADOS: As obesas mórbidas apresentaram uma idade pulmonar significativamente superior (50,1 ± 6,8 anos) às eutróficas (38,8 ± 11,4 anos). Não houve diferença entre a idade cronológica entre os grupos. Houve uma correlação significativa e positiva entre idade cronológica, massa corporal e IMC com a idade pulmonar (r = 0,3647, 0,4182, 0,3743, respectivamente). Houve uma correlação negativa entre a capacidade vital forçada (CVF), volume expiratório forçado no primeiro segundo (VEF1), razão (VEF1/CVF) e volume de reserva expiratório (VRE) com a idade pulmonar (r = -0.7565, -0.8769, -0.2723, -0.2417, respectivamente). CONCLUSÃO: A idade pulmonar das obesas mórbidas encontra-se aumentada e está associada com o aumento da massa corporal e IMC.

Respostas cardiopulmonares agudas de mulheres no treinamento de força / Acute cardiopulmonary responses of women in strength training

OBJETIVO: Investigar as respostas cardiopulmonares de uma sessão de treinamento de força em mulheres jovens. MÉTODO: Participaram do estudo 23 mulheres, com idade entre 18 e 29 anos. Todas as voluntárias foram submetidas aos seguintes testes: cardiopulmonar e de uma repetição máxima (1-RM). O protocolo de treinamento de força teve ênfase em hipertrofia muscular, três séries de oito a 12 repetições a 70% de 1-RM, com intervalos de um minuto e 30 segundos entre as séries. Durante a sessão de treinamento foi realizada a medida das variáveis cardiopulmonares por meio de analisador de gases metabólicos e módulo de telemetria. RESULTADOS: Os resultados do consumo de oxigênio da sessão de treinamento foram de 8,43 ± 1,76 ml/kg/min e da frequência cardíaca de 108,08 ± 15,26 bpm. Os resultados do consumo de oxigênio e da frequência cardíaca do treino foram inferiores (p < 0,01) ao do limiar ventilatório e das reservas do consumo de oxigênio e da frequência cardíaca. CONCLUSÃO: Os dados obtidos indicam que o presente protocolo de treinamento de força proporcionou pequena sobrecarga ao sistema cardiorrespiratório de mulheres jovens.

OBJETIVE: Investigate the cardiopulmonary responses of one strength training session in young women. METHOD: Twenty-three women aged between 18 and 29 years participated in this study. All the volunteers were submitted to the following tests: cardiopulmonary and one-repetition maximum (1-RM). The strength training protocol had emphasis on muscular hypertrophy, three sets from eight to twelve repetitions under 70% of 1-RM, with a one minute thirty-second break between sets. During the training session, the cardiopulmonary variables were measured with a metabolic gas analyzer and a telemetry module. RESULTS: The results of the oxygen consumption in the training session were from 8.43 + 1.76 ml/kg/min and of the heart rate of 108.08 + 15.26 bpm. The results of the oxygen consumption and of the heart rate in the training were lower (p < 0.01) than in the ventilatory threshold and of the oxygen consumption and the heart rate reserves. CONCLUSION: The obtained data show that the present protocol of strength training provided low overload to the cardiopulmonary system of young women.
