Abstract: For people with chronic obstructive pulmonary disease (COPD) the ability to perform functional activities for a prolonged duration is important for completion of daily tasks. While the Glittre-ADL test measures time taken to complete a series of functional activities, there is no test of endurance capacity for common daily activities. Is the Glittre Endurance test a valid and responsive test to measure endurance capacity for functional daily tasks in people with COPD? This was a cross-sectional study. Fifty-seven participants with COPD (mean ± SD age:69 ± 7 years FEV Mean ± SD of the Glittre Endurance test was 12.11 ± 6.43 min and 6.90 ± 4.40 min for the test at 90% and 100% speeds, respectively. When the 100% Glittre Endurance test 2 was compared to test 1, there was a 14% increase in test time, indicating a learning effect (p = 0.005). Following pulmonary rehabilitation (n = 20) the Glittre Endurance test increased by 3.12 min (29%), and the Glittre-ADL-noBP reduced by 0.33 min (10%). The Glittre Endurance test performed at 100% of the Glittre-ADL-noBP speed provided an appropriate endurance test time, and was more sensitive to change following pulmonary rehabilitation than the Glittre-ADL-noBP.

Abstract: ABSTRACT The mini-mental state examination (MMSE) is a screening test used worldwide for identifying changes in the scope of cognition. Studies have shown the influence of education, age and sex in the MMSE score. However, in Brazil, the studies consider only one factor to score it. The aim of this study was to establish a prediction equation for the MMSE. An exploratory cross-sectional study was developed and trained researchers examined participants at the community. The volunteers were evaluated by the MMSE and also by the Geriatric Depression Scale (GDS). The MMSE score was the dependent variable. Age, educational level, sex, and GDS score were the independent variables. Multivariate regression analysis was used to determine the model of best prediction value for MMSE scores. A total of 250 participants aged 20-99 years, without cognitive impairment, were assessed. The educational level, age, and sex explained 38% of the total variance of the MMSE score (p .0001) and resulted in the following equation: MMSE=23.350+0.265(years of schooling)-0.042(age)+1.323(sex), in which female=1 and male=2. The MMSE scores can be better explained and predicted when educational level, age, and sex are considered. These results enhance the knowledge regarding the variables that influence the MMSE score, as well as provide a way to consider all of them in the test score, providing a better screening of these patients.

Abstract: To evaluate the efficacy of an inspiratory muscle training protocol on inspiratory muscle function, functional capacity, and quality of life in patients with asthma. A single-blind, randomized controlled clinical trial. Community-based. Patients with asthma, aged between 20 and 70 years old, non-smokers. 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. 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. 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). About 8 weeks of inspiratory muscle training in patients with controlled asthma significantly increased inspiratory muscle strength and endurance.

Abstract: The relationship between rib cage (RC) motion abnormalities, dynamic hyperinflation (DH), and exercise capacity in people with COPD is controversial. To investigate RC distortion and operational chest wall volumes during moderate and high constant-rate exercises in people with COPD. Seven male participants [median(Q1-Q3) age: 63(60.0-66.0) years FEV PhRIB and PhREB significantly increased during both constant-rate exercise tests, without difference between them. In general, Vei of the chest wall significantly increased in both exercise intensities while Vee did not change. The occurrence of RC distortion seemed not to limit the exercise capacity in people with COPD evaluated, and it was present even in the absence of DH.
