Abstract: The upper limbs are involved in the activities of daily living (ADLs). Normal subjects usually perform such activities without noticing the energy cost, but patients with COPD report tiredness when performing them. This study was designed to assess the metabolic and ventilatory demands in patients with COPD during the performance of four ADLs involving the upper limbs. The patients were tested on two different days. Oxygen uptake (O(2)), carbon dioxide output (CO(2)), minute ventilation (E), and heart rate were measured while performing four ADLs for 5 min each: sweeping, erasing a blackboard, lifting pots, and replacing l s. Ten normal, young, male subjects (mean age, 27.9 years) were selected for testing the reproducibility of the methods, and 9 male patients with COPD (FEV(1), 32.5% mean age, 58.9 years) entered the study. The tests were reproducible for both groups. Patients with COPD presented a significant increase (p < 0.05) in O(2) (mean, 50.2% of maximum O(2)) and in E (mean, 55.7% of maximum voluntary ventilation [MVV]) in relation to initial resting conditions for all four activities. We conclude that when performing these four activities, patients with moderate-to-severe COPD present a high O(2), which may explain the tiredness reported by them during simple activities involving the upper limbs the high E/MVV may be associated to dyspnea.

Abstract: Abstract Introduction: According to studies from developed countries, post-stroke in iduals commonly have a low level of physical activity. Considering the benefits of maintaining a good level of physical activity in these subjects, it is important to provide specific and complete information, based on the assessment of all dimensions of physical activity, which supports interventions. Objective: To compare the physical activity levels between in iduals with stroke and matched healthy in iduals that use the public health system in Brazil considering the different dimensions of physical activity. Methods: In iduals with stroke (n = 11) and matched healthy in iduals (n = 11) were assessed. Physical activity levels, considering all dimensions -duration ( 3 MET), frequency (number of steps) and intensity (mean total energy expenditure per day) - were assessed using SenseWear® monitor for seven days. Descriptive statistics and between-groups comparisons were performed (α = 0.05). Results: The physical activity levels were significantly lower in in iduals with stroke when compared to matched healthy in iduals, considering all dimensions. The between-group differences in activity duration, frequency, and intensity were 74 minutes/day, 5,274 steps/day, and 2,134kJ/day, respectively. Conclusion: In iduals with stroke users of the Brazilian public health system have lower physical activity levels in different dimensions of physical activity than matched healthy in iduals. The assessment of the physical activity level of post-stroke in iduals is important for decision making in public health programs.

Abstract: O longo período de imobilidade na internação em unidade de terapia intensiva (UTI) desencadeia prejuízos aos sistemas musculoesquelético, cardiovascular, respiratório e neurológico. A reabilitação pulmonar na UTI, em especial o treinamento físico, visa restaurar a funcionalidade anterior ao episódio que determinou a necessidade da ventilação mecânica, reduzindo a dependência, prevenindo novas internações e, conseqüentemente, melhorando a qualidade de vida. Entretanto, é observada resistência na aplicação dessa modalidade de tratamento, devido ao receio das equipes. O objetivo do presente estudo foi efetuar uma revisão da literatura sobre as implicações dos programas de reabilitação pulmonar nas UTI. O levantamento bibliográfico foi feito nas bases de dados PubMed, Cochrane, PEDro e SciELO por meio dos descritores"reabilitação pulmonar""no cuidado intensivo" e"na unidade de terapia intensiva", além de estudos sugeridos por especialistas. Sete artigos (ensaios clínicos randomizados, estudos de coorte e retrospectivos) foram avaliados. Todos sugeriram que a reabilitação na UTI é benéfica e não causa efeitos colaterais. Os principais benefícios identificados foram a melhora da deambulação, aumento de força da musculatura respiratória e esquelética, além de melhora funcional ligada às atividades de vida diária. De acordo com os estudos analisados, a reabilitação pulmonar em UTI mostrou-se uma modalidade segura, bem tolerada e que determina efeitos positivos aos pacientes.

Abstract: Abstract Introduction: The Six-Minute Walk Test (6MWT) is widely used to assess functional capacity in children. The measure of work during 6MWT can add important information to the 6MWT assessment in this population as it relates to walking efficiency. Objective: To verify the determinants of work during the Six-Minute Walk Test (6MWTwork) in school-aged children. Method: This is a cross-sectional and exploratory study that included healthy children recruited from the public and private schools of the cities of Belo Horizonte and Uberlândia, Brazil. The inclusion criteria were: children aged 7 to 12 years without diagnosis of chronic cardiorespiratory disease, cognitive, behavioral disorder or physical function impairment (information obtained through self-report of those responsible for children). Exclusion criteria were children who refused to perform the 6MWT who did not understand the 6MWT or who did not answer the test commands. Three hundred and nineteen school-aged children were included in the study. Correlation analyses and multiple linear regression analysis were used to identify the variables associated with the 6MWTwork. Results: Age, height, nutritional status, physical activity and heart rate showed significant correlation with 6MWTwork (p .001) and explained 87% of its variation (p = 0.0001). Conclusion: Age, height, nutritional status and heart rate variation are determinants of 6MWTwork that is able to evaluate functional capacity of school-aged children.

Abstract: ABSTRACT Objective: To determine reference values for the six-minute pegboard and ring test (6PBRT) in healthy adults in Brazil, correlating the results with arm length, circumference of the upper arm/forearm of the dominant arm, and the level of physical activity. Methods: The participants (all volunteers) performed two 6PBRTs, 30 min apart. They were instructed to move as many rings as possible in six minutes. The best test result was selected for data analysis. Results: The s le comprised 104 in iduals, all over 30 years of age. Reference values were reported by age bracket. We found that age correlated with 6PBRT results. The number of rings moved was higher in the 30- to 39-year age group than in the 80-year age group (430.25 ± 77.00 vs. 265.00 ± 65.75), and the difference was significant (p 0.05). The 6PBRT results showed a weak, positive correlation with the level of physical activity (r = 0.358 p 0.05) but did not correlate significantly with any other variable studied. Conclusions: In this study, we were able to determine reference values for the 6PBRT in healthy adults in Brazil. There was a correlation between 6PBRT results and age.

Abstract: Dispnéia é a dificuldade que determinados in íduos, portadores de alguma doença pulmonar, cardíaca, metabólica ou psicogênica, têm de respirar, ou ainda a respiração desconfortável. Este sintoma, por acarretar redução das atividades funcionais, é um dos mais incapacitantes para estes pacientes. A dispnéia é um sintoma subjetivo e difícil de ser quantificado com exatidão, pois cada paciente o sente de uma forma diferente e, muitas vezes, o que é percebido pelo examinador não é a mesma sensação do paciente. Para esclarecer isso, esta pesquisa procurou reunir os métodos existentes de mensuração da dispnéia, com o objetivo de constatar qual o mais utilizado. Depois da análise de trinta e um artigos e da reunião de oito métodos que mensuram a dispnéia, concluiu-se que a escala modificada de Borg é o mais utilizado, seguido da Escala Analógica Visual, Escala do Conselho de Pesquisa Médica e Índice Basal de Dispnéia.

Abstract: A doença pulmonar obstrutiva crônica é progressiva, debilitante e diagnosticada após longa história de piora gradual. A dispnéia é o sintoma que mais interfere na execução das atividades profissionais, familiares, sociais e da vida diária dos pacientes com doença pulmonar obstrutiva crônica, levando-os ao sedentarismo e à queda na qualidade de vida. O objetivo deste artigo é abordar as limitações funcionais a que esses pacientes estão sujeitos, durante a realização de suas atividades da vida diária, e orientações para que os profissionais da saúde possam cuidar desses pacientes a fim de que obtenham uma maior funcionalidade. As orientações sobre o uso das técnicas de conservação de energia vêm sendo utilizadas nos programas de reabilitação pulmonar e também deveriam ser difundidas nos ambulatórios e hospitais. As atividades funcionais humanas envolvem as pernas e os braços, sendo estes últimos utilizados extensivamente para realizar atividades simples e complexas do cotidiano. Alguns estudos mostraram que os exercícios de braço não sustentados causam assincronia toracoabdominal e dispnéia em tempo mais curto e com menor consumo de oxigênio quando comparados com os exercícios de pernas. Tarefas simples podem apresentar consumo de oxigênio e ventilação minuto altos, justificando a sensação de dispnéia relatada pelos pacientes. Devido a isso, é conveniente adotar uma avaliação do impacto da incapacidade sobre a vida diária dos pacientes com doença pulmonar obstrutiva crônica. São discutidas e indicadas as técnicas de conservação de energia apropriadas como ferramenta para minimizar o desconforto desses pacientes.

Abstract: To assess the energy spent by COPD patients using or not using energy conservation techniques (ECTs) during activities of daily living (ADL). The patients were evaluated in two different situations as stated above. For both applications, the following variables were measured during four ADL with or without using postures recommended by ECTs: metabolic (oxygen consumption [V(O2)] and carbon dioxide production [V(CO2)]), ventilatory (minute ventilation), cardiovascular (heart rate [HR] and oxygen pulse), and dyspnea (Borg score). Sixteen male COPD patients (mean age, 62 years) with moderate-to-very-severe COPD (mean FEV1, 40%) participated in the study. The use of ECTs during ADL related to personal hygiene reduced V(O2) (13.4%), V(CO2) (12.8%), HR (13.7%), and Borg score (1 point) [p < 0.05]. Putting on and taking off shoes did not change V(O2), V(CO2), and HR but reduced the Borg score (0.6 point) [p < 0.05]. Storing groceries on high shelves reduced V(O2) (12.2%), V(CO2) (9.9%), HR (5.1%), and Borg score (0.75 point). Storing groceries on low shelves reduced V(O2) (28.1%), V(CO2) (24.3%), HR (5.4%), and Borg score (0.8 point) [p < 0.05]. The use of energy conservation techniques in COPD patients during ADL reduces energy cost and dyspnea perception.

Abstract: Patients with chronic obstructive pulmonary disease (COPD) may suffer dyspnea when performing unsupported arm exercises (UAE). However, some factors related to the tolerance of the upper limbs during these exercises are not well understood. Our investigation was to determine if an unsupported arm exercise test in patients with COPD accomplishing diagonal movements increases lactic acid levels also, we assessed the metabolic, ventilatory and cardiovascular responses obtained from the unsupported arm exercise test. The study used results of maximal symptom limited tests with unsupported arms and legs performed on 16 patients with COPD. In order to do the test, some metabolic, respiratory and cardiovascular parameters such as oxygen uptake (VO 2 ), carbon dioxide production (VCO 2 ), respiratory rate (RR), pulmonary ventilation (VE), heart rate (HR) and blood pressure (BP) were measured during the exercise tests. Furthermore, blood lactate concentration was measured during the arm test. We detected a significant increase in the mean blood lactate concentration, VO 2 , VCO 2 , VE and RR from the resting to the peak phase of the UAE test. The mean values of VO 2 , VCO 2 and VE obtained at the peak of the UAE test corresponded to 52.5%, 50.0% and 61.2%, respectively, of the maximal values obtained at the peak of the leg exercise test. In comparison, the mean heart rate and systolic arterial blood pressure were significantly lower at the peak of the UAE test than at the peak leg exercise test and corresponded to 76.2% and 83.0%, respectively. Unsupported incremental arm exercises in patients with COPD increases blood lactic acid levels.

Abstract: ABSTRACT Objective: To establish reference values for the Unsupported Upper Limb EXercise (UULEX) test, which measures peak arm exercise capacity, in healthy adults in Brazil. Methods: This was a cross-sectional study, involving presumably healthy in iduals ≥ 30 years of age who completed questionnaires and underwent spirometry. All of the in iduals underwent two UULEX tests 30-min apart. The outcome measure was the maximum time (in min) to completion of the test. Results: We included 100 in iduals between 30 and 80 years of age. The mean test completion time was 11.99 ± 1.90 min among the women and 12.89 ± 2.15 min among the men (p = 0.03). The test completion time showed statistically significant correlations with age (r = −0.48 p 0.001), gender (r = 0.28 p = 0.004), body mass index (BMI, r = −0.20 p = 0.05), and height (r = 0.28 p = 0.005). Linear regression analysis showed that the predictors of UULEX completion time were age (p = 0.000), BMI (p = 0.003), and gender (p = 0.019), which collectively explained 30% of the total variability. The mean UULEX completion time was 6% lower for the women than for the men. Conclusions: The present study was able to establish reference values for the UULEX test in healthy adults in Brazil. The values were influenced by age, gender, and BMI.

Abstract: RESUMO A força dos músculos respiratórios (FMR) - pressão inspiratória máxima [PImáx] e pressão expiratória máxima [PEmáx] - apresentam variação quando estimadas por equações de predição. O objetivo deste estudo foi verificar se a classificação da PImáx obtida pelas equações de predição propostas por autores brasileiros é semelhante e concordante. A amostra foi constituída por 18 pacientes estáveis com disfunções cardiorrespiratória, neurológica e fraqueza muscular respiratória. A PImáx foi medida pelo manovacuômetro analógico e comparada com as equações de predição de autores brasileiros. Apenas dois autores detectaram fraqueza muscular inspiratória (p ,0001). Ao avaliar a concordância entre autores (Bias), verificou-se baixa concordância entre os valores preditos pelas equações, exceto entre os autores que detectaram fraqueza muscular inspiratória nos pacientes avaliados.

Abstract: The anaerobic threshold (AT) provides information on functional capacity in heart failure (HF). However, the visual determination of the AT by ventilatory methods is subjective, being susceptible to differences between examiners. To evaluate the inter- and intra-examiner reproducibility in the determination of the AT in patients with mild to moderate HF, using visual-graphic and V-slope methods. To compare and correlate the results. After performing a cardiopulmonary exercise test on a treadmill, visual-graphic and V-slope methods were used for the analysis of the AT. To assess the reproducibility, three examiners determined the AT twice by each method, on different days. For statistical analysis, we used intra-class correlation coefficient (ICC) with p <0.05. We evaluated a total of 16 subjects, with a mean age of 45.9 +/- 9.7 years, left ventricle ejection fraction of 20.5 +/- 8.1%, and peak exercise oxygen consumption of 20.6 +/- 7.8 mL/kgmin-1. The intra-examiner reproducibility was high in both methods for the three examiners, with ICC values between 0.87 and 0.99. The inter-examiner reproducibility was moderate in both visual-graphic method (ICC = 0.69) and V-slope method (ICC = 0.64). When comparing methods, the ICC found was 0.91. AT determination by visual-graphic and V-slope methods showed high and moderate inter- and intra-examiner reproducibility, respectively. Moreover, both methods showed good agreement when compared with each other. These results suggest that both methods can be used in a reproducible way in AT assessment of patients with mild to moderate HF.

Abstract: A mensuração das pressões respiratórias máximas - método de avaliação das condições de força dos músculos respiratórios - é um teste voluntário e esforço-dependente, com aplicações clínicas de ordem diagnóstica e terapêutica. Há uma grande variedade de equipamentos e interfaces para sua execução, o que acarreta uma relativa ausência de padronização. O objetivo deste estudo foi identificar os diferentes equipamentos, procedimentos e forma de interpretar a mensuração das pressões respiratórias máximas entre fisioterapeutas brasileiros. Dezenove fisioterapeutas respiratórios, de 13 diferentes instituições, situadas em três regiões do país, responderam a um questionário sobre esses aspectos. Os resultados mostram que prevaleceu o uso de manovacuômetro analógico (60%), com tubo de silicone (60%) e interface do tipo bocal tubular (53,4%), contendo orifício de fuga de 1 a 2 mm de diâmetro (86,6%), associado ao uso de clipe nasal (100%). Na mensuração, foi observado um número mínimo de três testes aceitáveis e reprodutíveis (80%) e, para a análise dos valores encontrados, todos usam valores de referência ou equações preditivas. Os dados sugerem que existe uma relativa uniformidade em relação à mensuração das pressões respiratórias máximas entre fisioterapeutas brasileiros.

Abstract: RESUMO O objetivo deste estudo foi avaliar e comparar respostas metabólicas, cardiovasculares e ventilatórias do incremental shuttle walk test (ISWT) e do Glittre activities of daily living test (Glittre-ADL test). Trata-se de um estudo transversal, realizado com in íduos saudáveis. A capacidade funcional (CF) foi avaliada pela distância percorrida e consumo de oxigênio pico (VO2pico) no ISWT e pelo tempo gasto e VO2 no Glittre-ADL test. Trinta in íduos percorreram 656,67 (IC95%:608,8-704,5) metros no ISWT e executaram o Glittre-ADL test em 2,4 (IC95%:2,2-2,6) minutos. O VO2 pico do ISWT foi 27,8 (IC95%25,6-29,9) versus 22,2 (IC95%20,5-24,1)mL×kg−1×min−1 (p ,001) no estado estável (EE) do Glittre-ADL test. As correlações entre distância percorrida no ISWT e o tempo gasto no Glittre-ADL test, o VO2pico do ISWT e o VO2 no EE do Glittre-ADL test e a FC no pico do ISWT e no EE do Glittre-ADL test foram de moderada a alta magnitude. O Glittre-ADL test apresenta menores respostas metabólicas, cardiovasculares e ventilatórias se comparado ao ISWT.

Abstract: The measurement of maximal respiratory pressure (MRP) is a procedure widely used in clinical practice to evaluate respiratory muscle strength through the maximal inspiratory pressure (P(Imax)) and maximal expiratory pressure (P(Emax)). Its clinical applications include diagnostic procedures and evaluating responses to interventions. However, there is great variability in the equipment and measurement procedures. Understanding the impacts of the characteristics of different interfaces can augment the repeatability of this method and help to establish widely applicable predictive equations. The aim of this study was to evaluate the influence of 4 different interfaces on a subject's capacity to generate MRP and the impact of these interfaces on the repeatability of these measurements. Fifty healthy subjects (mean ± SD age 26.36 ± 4.89 y) with normal spirometry were evaluated. MRP was measured by a digital manometer connected to 4 interfaces using different combinations of mouthpieces and tubes. The following variables were analyzed: maximum mean pressure, peak pressure, plateau pressure, and plateau variation. Analysis of variance for repeated measures or a Friedman test was used to compare the 4 interfaces, with P < .008 after Bonferroni adjustment considered significant. There was no significant difference between the 4 interfaces with respect to maximum mean pressure, peak pressure, plateau pressure, or plateau variation for P(Imax) (P ≥ .49) or P(Emax) (P ≥ .11), nor did the number of tests performed to fulfill the criteria of repeatability for P(Imax) (P = .69) or P(Emax) (P = .47) differ among the 4 interfaces. P(Imax) and P(Emax) values seem not to be influenced by the different interfaces studied, suggesting that patient comfort and availability of interfaces can be considered.
