“…When COPD becomes aggravated, patients suffer from deteriorated functional status and limitations in daily life [28]: physical activity is reduced in patients with GOLD [3] stage 1, and this reduction further worsens with disease severity, being the patients with COPD GOLD stage 4 very inactive [13]. A significant association between COPD severity status and walking and abnormalities was also observed in self-reported reports [45].…”

“…This is consistent with the findings by Yentes et al [22], who noticed larger step width just in COPD GOLD 3 and 4 stages. In sum, deficits in functional balance, coordination, and mobility were associated with disease severity or with differences in activity levels [7,28], and the severe GOLD categories were associated with worse global gait and pace characteristics [27]. Thus, combining data from patients belonging to different stages of the disease could have had the effect of weakening results and masking possible relevant differences between stages of the disease and/or healthy controls.…”

“…There is a general consensus on the fact that patients with COPD walk slower in tests like the 6MWT than healthy age-matched individu als [19,28,29]. However, as speed is responsible of considerable changes in gait patterns [30], to exclude a possible confounding factor and to better identify COPD-specific characteristics, gait should be evaluated at similar speeds as done in [22,25].…”

Gait analysis in patients with chronic obstructive pulmonary disease: a systematic review

Background: Gait instability is a major fall-risk factor in patients with chronic obstructive pulmonary disease (COPD). Clinical gait analysis is a reliable tool to predict fall onsets. However, controversy still exists on gait impairments associated with COPD. Research question: Thus, the aims of this review were to evaluate the current understanding of spatiotemporal, kinematic and kinetic gait features in patients with COPD. Methods: In line with PRISMA guidelines, a systematic literature search was performed throughout Web of Science, PubMed Medline, Scopus, PEDro and Scielo databases. We considered observational cross-sectional studies evaluating gait features in patients with COPD as their primary outcome. Risk of bias and applicability of these papers were assessed according to the QUADAS-2 tool. Results: Seven articles, cross-sectional studies published from 2011 to 2017, met the inclusion criteria. Sample size of patients with COPD ranged 14-196 (mean age range: 64-75 years). The main reported gait abnormalities were reduced step length and cadence, and altered variability of spatiotemporal parameters. Only subtle biomechanical changes were reported at the ankle level. Significance: A convincing mechanistic link between such gait impairments and falls in patients with COPD is still lacking. The paucity of studies, small sample sizes, gender and disease status pooling were the main risk of biases affecting the results uncertainty. Two research directions emerged: stricter cohorts characterization in terms of COPD phenotype and longitudinal studies. Quantitative assessment of gait would identify abnormalities and sensorimotor postural deficiencies that in turn may lead to better falling prevention strategies in COPD.

“…1 However, the objective severity of the disease is only partly associated with its impact on patients’ daily life. 2 Rather, patients’ perceptions of their disease (ie, their illness perceptions) drive how they cope with the illness, their quality of life (QoL), and their behavioral responses to the illness and its consequences (ie, self-management). 3 It follows that addressing maladaptive, unhelpful illness perceptions in clinical care for patients with COPD translates into more adequate coping, self-management skills, and QoL.…”

BackgroundGiven the increasing importance of patient-reported outcomes (PRO) in quality medical care, we examined the value and feasibility of an innovative method for assessing patients’ illness perceptions, represented in drawings made by patients with COPD of their lungs.AimThe aim of our study was: to study patients’ representation of COPD as reflected in their drawings of their lungs; and to examine scores on a validated measure that assesses illness perceptions (ie, Brief Illness Perception Questionnaire [B-IPQ]).Patients and methodsOne hundred outpatients with COPD, mean age 70 years, selected from a pharmacy database, participated and 98 filled out the B-IPQ. Eighty-seven patients completed the drawing task.ResultsThe illness perceptions as reflected in the responses to the B-IPQ scales represented a quite optimistic view of COPD and its consequences. The drawings of the lungs reflected a considerable discordance between patients’ representations and medically accepted representations of lungs of a person with COPD.ConclusionAssessing illness perceptions in clinical care and research about COPD offers opportunities to identify goals for patient education and self-management. Inviting patients to draw their illness is an innovative and promising approach to assessing PRO.

“…(6) The Manchester Respiratory Activities of Daily Living questionnaire (MRADL) is one of the physical disability PROMs for assessing ADL limitations in patients with COPD. (6)(7)(8)(9) The MRADL is a disease-specific assessment tool that is valid, reliable, and responsive to pulmonary rehabilitation, (10) as well as being a predictor of premature death in patients with COPD. (11,12) Although the MRADL has been translated into Portuguese and cross-culturally adapted for use in the COPD population of Brazil, (13) it has yet to be validated in that population.…”

The Brazilian Portuguese-language version of the Manchester Respiratory Activities of Daily Living questionnaire: construct validity, reliability, and measurement error

Objective:To test the construct validity, reliability, and measurement error of the Brazilian Portuguese-language version of the Manchester Respiratory Activities of Daily Living (MRADL) questionnaire in patients with COPD. Methods: We evaluated 50 patients with COPD, among whom 30 were men, the mean age was 64 ± 8 years, and the median FEV 1 as a percentage of the predicted value (FEV 1 %predicted) was 38.4% (interquartile range, 29.1-57.4%). Pulmonary function and limitations in activities of daily living (ADLs) were assessed by spirometry and by face-to-face application of the MRADL, respectively. For the construct validity analysis, we tested the hypothesis that the total MRADL score would show moderate correlations with spirometric parameters. We analyzed inter-rater reliability, test-retest reliability, inter-rater measurement error, and test-retest measurement error. Results: The total MRADL score showed moderate correlations with the FEV 1 /FVC ratio, FEV 1 in liters, FEV1%predicted, and FVC%predicted, all of the correlations being statistically significant (r = 0.34, r = 0.31, r = 0.42, and r = 0.38, respectively; p < 0.05 for all). For the reliability and measurement error of the total MRADL score, we obtained the following inter-rater and test-retest values, respectively: two-way mixed-effects model intraclass correlation coefficient for single measures, 0.92 (95% CI: 0.87-0.96) and 0.89 (95% CI: 0.81-0.93); agreement standard error of measurement, 1.03 and 0.97; smallest detectable change at the individual level, 2.86 and 2.69; smallest detectable change at the group level, 0.40 and 0.38; and limits of agreement, −2.24 to 1.96 and −2.65 to 2.69. Conclusions: In patients with COPD in Brazil, this version of the MRADL shows satisfactory construct validity, satisfactory interrater/test-retest reliability, and indeterminate inter-rater/test-retest measurement error.
