FUNCTIONAL STATUS IN PERIPHERAL ARTERIAL DISEASE: REHABILITATED VERSUS NON-REHABILITATED.

OBJECTIVE: to analyze patient perception of functional status related to activity and participation of rehabilitated and non-rehabilitated individuals with PAD. METHODS: Cross-sectional study assessing the activity and participation domain using the Human Activity Profile (HAP) questionnaire and the Participation Scale (P-scale), respectively. Groups were compared using Chi-square test and unpaired t-test. RESULTS: A total of 87 individuals (36 rehabilitated) with 65.28 ± 8.29 years (66.7% male) were included. HAP classified 58.6% of individuals with weak or inactive physical activity level, and approximately half of the sample did not have participation restriction. HAP scores and P-scale (locomotion inside and outside home) were lower in non-rehabilitated than rehabilitated individuals. CONCLUSION: Individuals with PAD presented little participation restriction and a great activity limitation, the last one being more evident among non-rehabilitated.

Concurrent validity between field tests and cardiopulmonary exercise testing in patients with idiopathic pulmonary fibrosis.

BACKGROUND: Maximal treadmill cardiopulmonary exercise testing is the gold standard for assessing functional capacity in patients with idiopathic pulmonary fibrosis (IPF). PURPOSE: Primarily to investigate the concurrent validity between three field tests and cardiopulmonary exercise testing in these patients. METHODS: Patients performed the cardiopulmonary exercise testing, a six-minute walk test, an incremental shuttle walk test, and, the Glittre-ADL test. For cardiopulmonary exercise testing, the ten seconds with the higher average of the peak oxygen uptake obtained within the last 30 seconds were considered; for six-minute walk test and incremental shuttle walk test, the longer distance; and for the Glittre-ADL test, the shorter time spent. Concurrent validity was assessed using different regression models based on the best adjustment of the data. RESULTS: Twenty-two patients with IPF were assessed, aged: 68 ± 8.1 years, 13 male. Patients presented a peak oxygen uptake of 16.5 ± 3.6 mL.kg-1.min1, achieving a distance of 512.6 ± 102.8 meters in the six-minute walk test and 415.7 ± 125.1 meters in incremental shuttle walk test. The walking distance in the six-minute walk test and the incremental shuttle walk test explained, respectively, 64% and 56% peak oxygen uptake variance observed in the cardiopulmonary exercise testing (R2 = 0.64,p < .001; R2 = 0.56,p < .001). The time spent in the Glittre-ADL test was 233.4 ± 88.7 seconds and explained 47% of the peak oxygen uptake variance observed in cardiopulmonary exercise testing (R2 = 0.47,p = .001). CONCLUSION: The six-minute walk test, incremental shuttle walk test, and Glittre-ADL test were considered valid tests to explain the peak oxygen uptake variance obtained by the cardiopulmonary exercise testing in patients with IPF.

Adherence to heart rate training zones in an exercise training program in adults with coronary artery disease

Objectives: To investigate the effect of exercise intensity on functional capacity in individuals with coronary artery disease, assess adherence to the heart rate training zone (HRTZ), and relationship between trained intensity and functional capacity. Methods: Retrospective study led with medical records of 54 outpatients with coronary artery disease in a public hospital. The prescribed intensity started at 50 ­60% of heart rate reserve, increasing monthly to 70 ­80% by the third month. Spearman's test was used to assess the correlation between improvement in distance in the incremental shuttle walk test (ISWT), exercise intensity, and rating of perceived exertion (Borg­RPE). Adherence was classified as 'below' when HRTZ was not achieved in any phase of the program, 'intermediate' when HR was within the HRTZ for one or two months, and 'above' when HR was at or higher than HRTZ two months. Improvement was tested with t-test and one-way ANOVA. Results: 51.9% of participants had an increase in ISWT of ≥70 m (p < 0.0001). In at least one month, 50.9% trained below HRTZ. Trained intensity did not go below 8.6% of the prescribed minimal threshold of HRTZ. Changes in ISWT were not significantly correlated with exercise intensity (p = 0.87) or Borg­RPE (p = 0.16). Conclusion: While a significant increase in functional capacity was found, considerable heterogeneity in changes were observed. This may, in part, be related to adherence to HRTZ with progressive exercise intensity and to the variability in exercise volume incardiovascular rehabilitation programs.

Predictive validity of the Denver developmental screening test (Denver-II) to detect risk of developmental coordination disorder in preterm children.

INTRODUCTION: The Denver-II is widely used as a screening tool, however, no studies were found about its validity to predict the risk of Developmental Coordination Disorder (DCD) in preterm children. OBJECTIVE: To verify the predictive validity and accuracy of the Denver-II to identify the risk of DCD in preterm children. METHODS: Methodological study with 121 preterm children, evaluated with the Denver-II at ages 1, 2, 3, 4 and/or 5 years and with the Movement Assessment Battery for Children (MABC-2) at 7 years. Univariate binary logistic regression analyses were performed and ROC curves were derived. RESULTS: Children classified as suspect by Denver-II at 2, 3, and 4 years were, respectively, 3.45, 7.40 and 6.06 times more likely to have a risk of DCD on the MABC-2 (p < 0.05). The area under the ROC curve was considered fair for ages 2 (0.60, 95 % CI 0.50-0.70), 3 (0.61, 95 % CI 0.51-0.71) and 4 (0.64, 95 % CI 0.54-0.74) years. The greater the number of suspects in Denver-II over time, the greater the probability of risk of DCD in the MABC-2 (p < 0.001). CONCLUSIONS: Global developmental assessment with the Denver-II at ages 2 to 4 years is considered to have fair accuracy to discriminate risk of DCD at school age in children born preterm.

Variation in sociodemographic, clinical and functional characteristics of patients with chronic venous insufficiency in a single public health center.

OBJECTIVES: Describe and analyze the sociodemographic, clinical and functional characteristics of individuals with chronic venous insufficiency (CVI) and compare the clinical severity with levels of mobility. METHODS: Exploratory cross-sectional study in a single public health center. The study cohort comprised 99 individuals. INTERVENTIONS: Clinical, sociodemographic and physical activity level questionnaires were applied; we also evaluated ankle amplitude and sural triceps function. Descriptive statistics, independent t test and one-way ANOVA with post hoc Least Significant Difference (LSD) were performed. RESULTS: Ninety-nine participants (87.9% woman) with an average age with an average age of 60.6 ± 14 years who where recruited to the study. The cohort was composed of individuals were moderately active, 80% exhibited symptoms of the disease and approximately 40% reported reduced mobility. Individuals who had reduced mobility and less physical activity showed reduced ankle amplitude and muscle function (p <0.05). CONCLUSION: CVI impacts on functional capacity, even in individuals with less severe disease.

A Scoping Review of Measurement Tools Evaluating Awareness and Disease-Related Knowledge in Peripheral Arterial Disease Patients.

BACKGROUND: Peripheral arterial disease (PAD) is the third leading cause of atherosclerotic cardiovascular morbidity worldwide, with high prevalence and associated complications, and is often overlooked and undertreated. Research has shown that there is a profound lack of PAD-related knowledge and awareness; additionally, information sources are not often reliable and accessible. The objective of this scoping review was: (1) to identify and critically appraise instruments that measure patients' disease-related knowledge/awareness about PAD, and (2) to characterize the current state of knowledge/awareness levels among these patients. METHODS: This systematic review was conducted and reported in accordance with the PRISMA statement. Six databases (APA PsycInfo, CINAHL Ultimate, Embase, Emcare Nursing, Medline ALL and Web of Science Core Collection) were searched, and search strategies were developed utilizing the PICO framework. Potential studies of any methodological design were considered for inclusion through a snowball hand search. Data from the included articles were extracted by a reviewer, and the extraction accuracy was independently cross-checked by another author. RESULTS: The initial database search yielded 9832 records, of which sixteen studies (thirteen quantitative and three qualitative) were included. Only three questionnaires had their psychometric properties assessed. Questionnaire items focused on the following topics: definition/characteristics, risk factors/causes, treatment, complications, and personal issues regarding the perception/management of the disease. Overall, knowledge/awareness about PAD was low among patients. CONCLUSIONS: This study identified major gaps in PAD education, including the lack of availability of a validated measurement tool addressing all educational topics relevant to care and low knowledge/awareness of patients about their condition.

Feasibility of Remote Delivering an Exercise and Lifestyle Education Program for Individuals Living with Prediabetes and Diabetes in Brazil.

This study aimed to test the feasibility of remote delivering a 12-week exercise and lifestyle education program (ExLE) or a 12-week exercise program (Ex) for individuals with prediabetes and diabetes in terms of acceptability, implementation, practicality, and limited efficacy. The programs were internet- or telephone-based delivered, depending on the participants' internet access and technology literacy. Of the 196 individuals screened, 15 were included in the study (internet-based delivery (n = 13); telephone-based delivery (n = 2)). Twelve participants completed the program they were randomized to, and most reported being satisfied with the study interventions (acceptability). Data collection procedures, weekly follow-up, study website visits, and educational materials were proper (implementation), and the adherence rate to study interventions ranged from 24% to 58% (practicality). Additionally, both programs (ExLE and Ex) seemed to promote beneficial changes in functional capacity (limited efficacy). The internet-based remote delivery of the interventions showed feasibility. Therefore, in future trials, exercise and educational interventions can be internet-based remote delivered to individuals with prediabetes and diabetes with internet access and technology literacy. In addition, some adjustments to eligibility criteria, study websites, more accessible ways of recording exercise sessions and using educational materials, and an initial supervised exercise session are recommended.

Exercise and Lifestyle Education program for Brazilians living with prediabetes and diabetes: A pilot randomized trial.

AIMS: To test the Diabetes College Brazil Study feasibility, the acceptability of study interventions and their preliminary effectiveness, and describe the study protocol modifications due to the COVID-19 pandemic. METHODS: Single-center, double-blinded pilot randomized trial with two parallel groups, Exercise and Lifestyle Education (ExLE; 12-week exercise and educational interventions) and Exercise (Ex; 12-week exercise intervention only) involving patients with prediabetes or diabetes. Feasibility (eligibility, recruitment, retention, completeness of variables measures and participation rates), acceptability (satisfaction), and preliminary effectiveness of interventions (variables: functional capacity, physical activity (PA), exercise self-efficacy, diabetes knowledge, health literacy, adherence to Mediterranean food pattern, glycated hemoglobin (HbA1c), anthropometric measures, cardiac autonomic control, depression, and quality of life (QofL)). RESULTS: Eligibility, recruitment, retention, participation in exercise sessions, and education classes rates were 17%, 93%,82%, 76%, and 71%, respectively. Missing data in the post-intervention assessment (PA, HbA1c, cardiac autonomic control, anthropometric measures, depression, and QofL) were mainly related to research procedure modifications. The interventions were highly acceptable, and most variables improved farther in the ExLE, with moderate effect sizes for PA, diabetes knowledge, health literacy, cardiac autonomic control, and QofL. CONCLUSIONS: The Diabetes College Brazil Study is feasible, and the ExLE may benefit Brazilians living with prediabetes and diabetes.

Impairments in ankle range of motion, dorsi and plantar flexors muscle strength and gait speed in patients with chronic venous disorders: A systematic review and meta-analysis.

OBJECTIVE: To verify the differences in ankle range of motion (ROM), muscle strength of dorsi and plantar flexors, and gait speed among healthy subjects, and patients with chronic venous disorders (CVD) with and without venous leg ulcer. METHODS: A systematic review and meta-analysis (http://osf.io/b7n3k) were conducted following a search of MEDLINE, Web of Science, CINAHL, LILACS, Scopus, and EMBASE databases. RESULTS: Eight papers were included. The ankle ROM was significantly lower both in dorsiflexion and plantar flexion in patients with venous leg ulcer when compared to healthy individuals and CVD patients without venous leg ulcer. The muscle strength of the plantar flexors and gait speed were reduced in CVD patients when compared to healthy ones. CONCLUSION: Impaired muscle strength and gait speed can be detected in CVD patients compared to healthy individuals, and ankle ROM tends to be reduced in CVD patients even in the absence of venous leg ulcers.

Differences in health-related quality of life in patients with mild and severe chronic venous insufficiency: A systematic review and meta-analysis.

OBJECTIVE: Chronic venous insufficiency (CVI) has a broad spectrum of clinical expression, ranging from mild to severe cases, which negatively impacts the health-related quality of life (HRQoL). However, the comparison in HRQoL between mild and severe CVI has not yet been systematically discussed, which could assist in the adoption of preventive strategies METHODS: A systematic review and meta-analysis was conducted (protocol register https://osf.io/mr4aj/) following a search of the MEDLINE, CINAHL, Web of Science, LILACS, and Scopus databases, using the terms related to CVI and HRQoL. Observational studies that assessed the HRQoL in individuals with CVI in different degrees of severity were included, without date restriction RESULTS: We retrieved 4750 titles and abstracts and 9 were included in this review. The HRQoL was worse in patients with severe CVI compared to mild patients at Short-form of Health Survey (SF-36) (mean difference 11.02, 95% CI from 8.62 to 13.43; p<0.001), Chronic Venous Insufficiency Quality Of Life Questionnaire (CIVIQ-14) (mean difference 13.07; 95% CI from 11.33 to 14.82; p<0.001) and Aberdeen Varicose Veins Questionnaire (mean difference 7.7; 95% CI: -12.82 to -2.58; p=0.003), especially in the physical domains. There was no difference in the HRQoL between severe and mild patients at CIVIQ-20 (p=0.09) CONCLUSION: The HRQoL was worse in the physical domains in patients with severe CVI when compared to mild patients. However, the heterogeneity of the results was high and the data should be interpreted with caution.

Translation, cross-cultural adaptation, and psychometric properties of the Brazilian Portuguese version of the DiAbeTes Education Questionnaire (DATE-Q).

BACKGROUND: The DiAbeTes Education Questionnaire (DATE-Q) is a self-administered tool developed to evaluate disease-related knowledge and to assess knowledge of five core components of rehabilitation programs: physical exercise, diet, psychosocial well-being, disease self-management, and complications. OBJECTIVE: To translate and cross-culturally adapt into Brazilian Portuguese, and to test the psychometric properties of the DATE-Q for its use in Brazil. METHODS: The process of translation and cross-cultural adaptation consisted of five steps: translation into Brazilian Portuguese, synthesis of translation, back translation, expert committee, and pilot test of pre-final version. The pre-final version was applied to a sample of 30 patients with diabetes. Psychometric properties (internal consistency, reliability, construct validity, and ceiling and floor effects) of the final version of the Brazilian Portuguese version of the DATE-Q were tested in a sample of 200 adults with diabetes. RESULTS: There was no conceptual divergence between the original and the translated versions. Ten (50%) items of the DATE-Q were culturally adapted. Internal consistency (Cronbach's alpha coefficient = 0.6), reliability (intraclass correlation coefficient = 0.5), and construct validity (correlation between Diabetes Knowledge Scales and DATE-Q total scores: ρ = 0.7; P < 0.001) were confirmed. Ceiling or floor effects were not identified. The highest scoring item was about healthy eating. The average time for completion of the DATE-Q was 5 min and 51 s, and the completion rate was 100% for all items. CONCLUSION: The Brazilian Portuguese version of the DATE-Q showed adequate psychometric properties, and results suggested that the tool can be used to assess disease-related knowledge in adults with diabetes in Brazil.

Upper Limb Energy Demand During Unilateral Arm Crank Submaximal Exercise Testing in Individuals With Chronic Stroke.

OBJECTIVE: To investigate upper limb (UL) energy demand during unilateral arm crank submaximal exercise testing in individuals with stroke compared with healthy controls and the relationship between UL energy demand and UL activity in individuals with stroke. DESIGN: Cross-sectional, observational study. SETTING: Research laboratory. PARTICIPANTS: Individuals with chronic stroke (n=14) and controls (n=12), matched for age, sex, and body mass index (N=26). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: UL energy demand was measured as peak oxygen consumption (V̇o2)/peak load during unilateral arm crank submaximal exercise testing. UL activity was measured using the Box and Block Test (BBT) and Grooved Pegboard Test (GPT). RESULTS: The energy demand of the paretic side compared with the nonparetic side of the stroke group was 0.43 mL/kg/min/W (95% confidence interval, 0.03-0.83, P=.005) greater than the dominant compared with the nondominant side of the control group. The median difference between sides in peak V̇o2/peak load was 52% for the group with stroke compared with 11% for the control group. Positive correlations between the median percentage difference between the paretic and the nonparetic side of peak V̇o2/peak load and BBT were 0.72 (P=.004) and of V̇o2/peak load and GPT was 0.77 (P=.002). CONCLUSIONS: The higher energy demand of the paretic UL during unilateral arm crank submaximal exercise testing than the nonparetic and both UL of the controls together with the strong relationship between energy demand and UL activity suggest that the energy demand of the paretic UL has the potential to affect real-life UL activity after stroke.

Comparação das distâncias previstas e percorridas no incremental shuttle walking test em idosos comunitários / Comparación de las distancias predichas y recorridas en la incremental shuttle walking test en ancianos comunitarios / Comparison of predicted and covered distances in the incremental shuttle walking test in older adults

RESUMO O objetivo deste estudo foi avaliar a validade externa de três equações de referência para o cálculo da distância a ser percorrida no incremental shuttle walking test (ISWT) por idosos comunitários, e, por fim, identificar qual equação prediz melhor a distância nessa faixa etária. Foram selecionados 84 idosos cadastrados nas Unidades Básicas de Saúde de Diamantina, Minas Gerais. Os voluntários foram submetidos ao ISWT e a distância percorrida em metros até a interrupção do teste foi registrada e utilizada para comparação com as equações de predição. Os voluntários apresentaram média de idade de 73,15±5,89 anos e alguns comprometimentos de saúde comuns dessa faixa etária, sendo a maioria mulheres e praticantes de atividade física. A análise estatística demonstrou que houve interação entre os fatores, ou seja, existe diferença entre as distâncias obtidas pelo ISWT e as distâncias obtidas pelas equações. Houve diferença também nas comparações entre os sexos (p<0,05) e a Equação 1 apresentou maior força de correlação (p<0,0001; r=0,414) com a distância real percorrida em relação às outras equações. Portanto, este estudo demonstrou uma diferença na comparação das distâncias real e calculadas por três equações de predição do ISWT, sugerindo que as equações utilizadas podem superestimar a distância percorrida pelos idosos, e que entre essas a Equação 1 apresentou uma predição mais próxima da distância percorrida para a amostra de idosos avaliada.

RESUMEN El objetivo de este estudio fue evaluar la validez externa de tres ecuaciones de referencia para calcular la distancia recorrida de la incremental shuttle walking test (ISWT) para ancianos comunitarios, así como identificar la ecuación que mejor predice la distancia en este grupo de edad. Se seleccionaron a 84 ancianos inscritos en las Unidades Básicas de Salud de Diamantina, Minas Gerais (Brasil). Se aplicaron a los voluntarios la ISWT, y la distancia recorrida en metros hasta la interrupción de la prueba se registró y se utilizó para comparar con las ecuaciones de predicción. Los voluntarios tenían un promedio de edad de 73,15±5,89 años y algunos problemas de salud habituales en este grupo de edad, de los cuales la mayoría fue mujeres y practicantes de actividad física. El análisis estadístico mostró que hubo una interacción entre los factores, es decir, existe una diferencia entre las distancias obtenidas por ISWT y las distancias obtenidas por las ecuaciones. También hubo una diferencia en las comparaciones entre los sexos (p<0,05), y la Ecuación 1 mostró una mayor fuerza de correlación (p<0,0001; r=0,414) con la distancia real recorrida en relación con las otras ecuaciones. Por lo tanto, este estudio demostró una diferencia en la comparación de las distancias reales y calculadas por tres ecuaciones de predicción de ISWT, lo que sugiere que las ecuaciones utilizadas pueden sobreestimar la distancia recorrida por los ancianos y que entre estas la Ecuación 1 presentó una predicción más cercana a la distancia recorrida por la muestra evaluada.

ABSTRACT Our study aimed to evaluate the external validity of three reference equations for estimating the distance to be covered in the incremental shuttle walking test (ISWT) by older adults and to identify which equation best predicts the distance for this age group. In total, 84 older adults registered in the Health Centers of Diamantina, state of Minas Gerais, Brazil, were selected. The volunteers were subjected to the ISWT and the distance covered, in meters, until the interruption of the test was recorded and compared with the prediction equations. The volunteers had a mean age of 73.15±5.89 years and some health problems common to this age group, were mostly women, and physically active. Statistical analysis showed an interaction between the factors, that is, a difference between the distances covered the ISWT and the distances obtained by the equations. The analysis showed a difference between the men and women (p<0.05) and Equation 1 showed a greater correlation strength (p<0.0001; r=0.414) with the distance covered compared to the other equations. Therefore, our study showed a difference in the comparison of the distances covered and those estimated by three ISWT prediction equations, suggesting that the equations used may overestimate the distance covered by older adults, and that, Equation 1 showed a prediction closer to the distance covered by the older adults of the sample.

Efficacy of inspiratory muscle training on inspiratory muscle function, functional capacity, and quality of life in patients with asthma: A randomized controlled trial.

OBJECTIVE: To evaluate the efficacy of an inspiratory muscle training protocol on inspiratory muscle function, functional capacity, and quality of life in patients with asthma. DESIGN: A single-blind, randomized controlled clinical trial. SETTING: Community-based. SUBJECTS: Patients with asthma, aged between 20 and 70 years old, non-smokers. INTERVENTIONS: Participants were randomized into two groups: inspiratory muscle training group performed inspiratory muscle training 5 days a week for 8 weeks, consisting of six sets of 30 breaths per day with a training load ⩾50% of maximal inspiratory pressure, plus an educational program; the control group only received the educational program. MAIN MEASUREMENTS: Maximal inspiratory pressure, inspiratory muscle endurance, and the distance performed on the incremental shuttle walking test were assessed pre-intervention, post-intervention and at follow-up (3 months after the end of the intervention). The asthma quality of life questionnaire was applied pre and post-intervention. RESULTS: Data from 39 participants were analyzed. Maximal inspiratory pressure in percentage of predicted and endurance test duration were significantly higher post-intervention in the inspiratory muscle training group (∆ post-pre: 50.8% vs 7.3% of predicted - P < 0.001 and ∆ post-pre: 207.9 seconds vs 2.7 seconds - P < 0.001, respectively). There was no significant difference in the incremental shuttle walking distance between groups (∆ post-pre: 30.9 m vs -8.1 m, P = 0.165). Quality of life was perceived as significantly better, without a difference between groups (P > 0.05). CONCLUSIONS: About 8 weeks of inspiratory muscle training in patients with controlled asthma significantly increased inspiratory muscle strength and endurance.

Tissue oxygenation in peripheral muscles and functional capacity in cystic fibrosis: a cross-sectional study.

NEW FINDINGS: What is the central question of this study? How do peripheral muscle tissue oxygenation and physical conditioning levels of children and adolescents with cystic fibrosis compare to demographically matched controls? What is the main finding and its importance? Children and adolescents with cystic fibrosis consumed more oxygen, more quickly and exhibited slower recovery, demonstrating that there may have been deficiencies in oxygen supply related to both oxygen uptake and oxygen transport. ABSTRACT: Cystic fibrosis affects skeletal muscle performance and functional capacity. However, it is currently unclear how peripheral muscle behaviour is affected, especially in children and adolescents. To examine this, we compared tissue oxygenation of children and adolescents with cystic fibrosis against healthy volunteers. We also evaluated the functional capacity of participants via the modified shuttle test (MST) and assessed for associations between performance and near-infrared spectroscopy. A total of 124 participants enrolled. Participants were divided into either the cystic fibrosis group (CFG) or the healthy group (HG). Statistical comparisons between groups were evaluated with the Mann-Whitney U test and associations with functional capacity were evaluated using Spearman's correlation coefficient. CFG volunteers scored lower on the MST compared to the HG. They walked shorter distances (P = 0.001) with less efficiency because they performed the tests with a less efficient walking economy (P = 0.001) and a greater deoxyhaemoglobin concentration (P = 0.001). Further, they experienced reduced tissue oxygen saturation (P = 0.037) faster than the HG. As a result, they presented lower respiratory (P = 0.001) and lower heart (P = 0.001) rate values at the end of the MST, with a longer post-test heart rate recovery time (P = 0.005). There was a significant association between deoxygenation time and functional capacity. The CFG consumed more oxygen, more quickly, with a slower recovery, reflecting impairments in the dynamics of muscle oxygen extraction. The results suggest differences in functional capacity and haemodynamic recovery in children and adolescents with cystic fibrosis.

Association between heel-rise test performance and clinical severity of chronic venous insufficiency.

BACKGROUND: Peripheral pump dysfunction is important in identifying manifestations of chronic venous insufficiency. The association with disease severity may define better treatment strategies. OBJECTIVE: To evaluate the association between peripheral muscular pump performance by heel-rise test, age, physical activity, use of compression stockings, and chronic venous insufficiency clinical severity. METHODS: Subjects with chronic venous insufficiency were enrolled in the study (n = 172) and evaluated by clinical-etiology-anatomy-pathophysiology severity and heel-rise test. RESULTS: In model 1 of logistic regression, number of heel-rise test repetitions, age, and physical activity explained 47% of clinical-etiology-anatomy-pathophysiology severity (p = 0.0001), physical activity contributed the most. In model 2, heel-rise test repetition rate, age, and physical activity explained 46.4% of clinical-etiology-anatomy-pathophysiology severity (p = 0.0001), repetition rate contributed the most. Conclusion: There was an inverse association between muscular pump performance and physical activity with clinical-etiology-anatomy-pathophysiology severity, muscular pump repetition rate contributed to a less severe outcome.

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 indivíduos 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 indivíduos 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<0,001) 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.

RESUMEN El presente estudio tuvo el objetivo de evaluar y comparar las respuestas metabólicas, cardiovasculares y ventilatorias de incremental shuttle walk test (ISWT) y de Glittre activities of daily living test (Glittre-ADL test). Es un estudio transversal realizado con individuos sanos. La capacidad funcional (CF) se evaluó utilizando la distancia recorrida y consumo máximo de oxígeno (VO2máx) en el ISWT y el tiempo empleado y VO2 en el Glittre-ADL test. Treinta individuos caminaron 656,67 (IC95%:608,8-704,5) metros en el ISWT y realizaron el Glittre-ADL test en 2,4 (IC95%:2,2-2,6) minutos. El VO2 máx del ISWT fue de 27,8 (IC95%25,6-29,9) versus 22,2 (IC95%20,5-24,1)mL×kg−1×min−1 (p<0,001) en el estado estable (EE) del Glittre-ADL test. Las correlaciones entre la distancia recorrida en el ISWT y el tiempo empleado en el Glittre-ADL test, el VO2máx del ISWT y el VO2 en el EE de Glittre-ADL test y la FC en el máximo del ISWT y en el EE de Glittre-ADL test fueron de moderada a alta magnitud. El Glittre-ADL test presenta respuestas metabólicas, cardiovasculares y ventilatorias más bajas en comparación con el ISWT.

ABSTRACT The aim of the study was to assess and compare the cardiovascular, ventilatory and metabolic responses of the Incremental Shuttle Walk test (ISWT) and Glittre Activities of Daily Living test (Glittre-ADL test). This is a cross-sectional study with individuals. The functional capacity (FC) was evaluated by distance and peak oxygen consumption (VO2peak) in the ISWT and time spent and VO2 in Glittre-ADL test. Thirty individuals went through 656.67 (CI95%:608.8-704.5) meters at the ISWT and performed the Glittre-ADL test in 2.4 (CI95%:2.2-2.6) minutes. The peak VO2 of the ISWT was 27.8 (CI95%25.6-29.9) vs. 22.2 (CI95%20.5-24.1) mL×kg−1×min−1 (p<0.001) in the steady state (SS) of the Glittre-ADL test. Correlations between distance traveled in the ISWT and the time spent in Glittre-ADL test, VO2 peak of ISWT and VO2 in SS of Glittre-ADL test and HR at the ISWT peak and at the Glittre-ADL test SS were moderate to high magnitude. The Glittre-ADL test has lower metabolic, cardiovascular and ventilatory responses compared to ISWT, despite correlations between variables.

Validation of the International Classification of Functioning, Disability and Health Core Set for obstructive pulmonary diseases in the perspective of adults with asthma.

Purpose: To validate the Comprehensive and Brief International Classification of Functioning, Disability and Health Core Sets for obstructive pulmonary diseases from the perspective of adults with asthma.Methods: This was a qualitative, cross-sectional study. Individual interviews with questions related to the disease and its impact on the patient's life were performed. The meaning condensation procedure was used for analysis.Results: Thirty-five participants (26 females, 41 ± 13 years old) were interviewed. A total of 405 concepts were identified, and 348 were associated to the components Body Functions (n = 168), Body Structures (n = 22), Activities and Participation (n = 33), Environmental Factors (n = 125). These concepts were linked to 61 categories: second level (n = 25), third level (n = 33), fourth level (n = 3), which confirmed 41% and 77% of those included in the Comprehensive and Brief Core Sets, respectively.

Supervised Exercise Therapy for Intermittent Claudication.

Highlights the findings and application of Cochrane reviews and other evidence pertinent to the practice of physical therapy. The Cochrane Library is a respected source of reliable evidence related to health care. Cochrane systematic reviews explore the evidence for and against the effectiveness and appropriateness of interventions-medication, surgery, education, nutrition, and exercise-and the evidence for and against the use of diagnostic tests for specific conditions. Cochrane reviews are designed to facilitate the decisions of clinicians, patients, and others in health care by providing a careful review and interpretation of research studies published in the scientific literature. Each article in this Physical Therapy (PTJ) series will summarize a Cochrane review or other scientific evidence resource on a single topic and will present clinical scenarios based on real patients to illustrate how the results of the review can be used to directly inform clinical decisions. This article focuses on the effectiveness of supervised exercise therapy for intermittent claudication. Can supervised exercise therapy help a person with intermittent claudication?
