The London Chest Activity of Daily Living scale cut-off point to discriminate functional status in patients with chronic obstructive pulmonary disease

Functional capacity using sit-to-stand tests in people with chronic obstructive pulmonary disease and its relationship with disease severity-a cross-sectional study with matched controls

BACKGROUND

Functional capacity impairment is a crucial consequence of chronic obstructive pulmonary disease (COPD). Although it can be identified with simple tests, such as the sit-to-stand tests, its prevalence, relation with disease severity, and the characteristics of people presenting this impairment remain unknown.

OBJECTIVE

To explore the functional capacity of people with COPD.

METHODS

A cross-sectional study with people with COPD and age-/sex-matched healthy controls was conducted. Functional capacity was assessed with the 5-repetitions (5-STS) and the 1-minute (1-minSTS) sit-to-stand tests. People with COPD were grouped according to the Global Initiative for Chronic Obstructive Lung Disease (GOLD) classifications. Comparisons between people with COPD and healthy controls, and among GOLD groups were established. Associations between symptoms, muscle strength, quality of life, and measures of functional capacity were explored.

RESULTS

302 people with COPD [79% male; mean (SD) 68 (10) years old] and 304 healthy controls [75% male; 66 (9) years old] were included. 23% of people with COPD presented impairment in the 5-STS and 33% in the 1-minSTS. People with COPD from all GOLD classifications presented significantly lower functional capacity than healthy controls (5-STS: COPD median [1st quartile; 3rd quartile] 8.4 [6.7; 10.6] versus healthy 7.4 [6.2; 9.3] s; 1-minSTS: COPD 27 [21; 35] vs healthy 35 [29; 43] reps). Correlations with symptoms, muscle strength, and quality of life were mostly weak (5-STS: rs [-0.34; 0.33]; 1-minSTS: rs [-0.47; 0.40]).

CONCLUSION

People with COPD have decreased functional capacity independently of their GOLD classifications. The prevalence of functional impairment is 23-33%. Because impaired functional capacity is a treatable trait not accurately reflected by other outcomes, comprehensive assessment and management is needed.

The effect of rosemary hydroalcoholic extract on cognitive function and activities of daily living of patients with chronic obstructive pulmonary disease (COPD): A clinical trial

BACKGROUND

In patients living with chronic obstructive pulmonary disease (COPD), cognitive impairment and reduced activities of daily living (ADLs) are associated with poor clinical outcomes.

AIM

The aim of the present study was to determine the effect of rosemary hydroalcoholic extract on cognitive function and ADLs in patients with COPD.

METHODS

A total of 77 COPD patients aged 40-80 years were assigned to two intervention and control groups by random stratified block method in the current tripleblind clinical trial. The intervention group received 500 mg rosemary capsules and the control group received oral capsules containing corn powder twice a day, one to two hours before breakfast and dinner, for two months. The Montreal Cognitive Assessment-Basic (MoCA-B), London Chest Activity of Daily Living scale (LCADL) and Lawton Instrumental Activities of Daily Living (IADL) were used to measure cognitive function and the measure of basic and instrumental daily life activities, before and after the intervention, respectively.

RESULTS

The mean total score of cognitive function (P = 0.022) and the two subscales of abstraction (P = 0.003) and naming (P = 0.034) significantly increased after the intervention in the intervention group. There was no significant difference between the intervention and control groups in terms of changes in the mean scores of IADL and LCADL (P < 0.05). The final statistical model showed that the changes in the total mean score of cognitive function (P = 0.014) and IADL (P = 0.047) in intervention group patients are significantly higher than in the control group after adjusting the effect of obstructive sleep apnea (OSA).

CONCLUSION

The rosemary hydroalcoholic extract can be effective in improving cognitive function and IADL in patients with COPD, but not LCADL.

Reliability and validity of the online application of London Chest Activity of Daily Living scale in assessing dyspnea-related functional impairment in individuals after hospitalization for COVID-19

PURPOSE

To investigate the test-retest reliability and construct validity of the LCADL scale applied via online form in individuals after hospitalization for COVID-19.

METHODS

Methodological study. After hospitalization for COVID-19 individuals completed the LCADL via online form at two separate times. They also answered the post-COVID-19 Functional Status Scale (PCFS), dyspnea, fatigue, and health perception scales, modified Medical Research Council (MRCm), Short Form Health Survey 36 (SF-36). Hospitalization data were collected from the individual's medical record.

RESULTS

104 individuals participated in the study (57 men, 45.2 ± 11.9 years). The LCADL showed moderately to high test-retest reliability (ICC: 0.73-0.86; p < 0.001), there was no difference in scores between test and retest (p > 0.05), the mean difference between the applications was smaller than the standard error of measurement and the internal consistency was adequate (Cronbach's α = 0.70-0.94). In addition, it demonstrated adequate construct validity, showing correlations with PCFS, dyspnea perception, fatigue and health scales, mMRC, SF-36, and length of stay in the Intensive Care Unit (p < 0.05). The LCADL as percentage of the total score presented a significant floor effect (25%).

CONCLUSION

The LCADL applied online was reliable and valid for assessing limitations due to dyspnea in ADL in individuals after hospitalization for COVID-19.

A Prospective Study of Patients with Persistent Symptoms after SARS-CoV-2 Infection Referred to Physical Medicine and Rehabilitation

INTRODUCTION

New evidence and extrapolated data from other coronaviruses suggest that symptoms and consequences of COVID-19 may persist beyond the cure. The aims of this study were to evaluate persistent symptoms after SARS-CoV-2 infection and its impact on physical condition, activities of daily living, and quality-of-life; establish whether symptom persistence is associated with higher disability; and document the evolution of the multiple domains after a home exercise program.

METHODS

Prospective study with patients referred to a Physical and Rehabilitation Medicine clinic, after SARS-CoV-2 infection. Patient evaluations, including a symptom questionnaire, the 1-Min Sit-to-stand test (1-MSTS), the EQ-5D questionnaire and the London Chest Activity Daily Living (LCA-DL) questionnaire, were performed before and after a home exercise program.

RESULTS

Seventy-four patients were included. The majority (n = 71) had been hospitalized (mean stay 19.66 ± 13.35 days), 51% required intensive care. At first evaluation, 54 days after symptom onset, a mean of 18.6 repetitions in the 1-MSTS were performed. The percentage of LCA-DL was above 28% in 23% of the patients. Impairments on EQ-5D were present in 44% for mobility and 44% for anxiety/depression. Mean EQ-5D VAS was 66.5 out of 100. Fifty-one (70%) had at least one persistent symptom (Symptomatic Group), while 22 (30%) were asymptomatic (Asymptomatic Group). The Symptomatic Group had statistically significantly worse mean results on 1-MSTS (16.8 vs 22.9; p < 0.001), % LCA-DL score, EQ-D5 (7.8 vs 5.7; p < 0.001) and EQ-D5-VAS. No patient characteristic, clinical background, comorbidity, or hospitalization characteristics was significantly different between groups. Every patient was given a home exercise program; 47 patients joined an additional rehabilitation program or were clinically discharged and were therefore excluded from the second evaluation. Twenty-seven patients participated in a second evaluation. In the matched analysis, mean 1-MSTS improved by 3.4 repetitions. Mean LCA-DL, mean EQ-5D score (7.1 to 6.6) and EQ-VAS score changed favourably and significantly.

CONCLUSION

Two months after infection by SARS-CoV-2, persistent symptoms were frequent in patients referred to a Physical Medicine and Rehabilitation clinic. Additionally, the SARS-CoV-2 infection, as well as the persistence of symptoms, had a negative impact in the physical condition and functionality in ADL and quality-of-life. With a home exercise program in place, a statistically significant improvement was observed. Referral of patients with persistent symptoms to Physical and Rehabilitation Medicine may be warranted.

Feasibility of a Home-Based Cognitive-Physical Exercise Program in Patients With Chronic Obstructive Pulmonary Disease: Protocol for a Feasibility and Pilot Randomized Controlled Trial

BACKGROUND

Chronic obstructive pulmonary disease (COPD) is a progressive condition associated with physical and cognitive impairments contributing to difficulty in performing activities of daily living (ADLs) that require dual tasking (eg, walking and talking). Despite evidence showing that cognitive decline occurs among patients with COPD and may contribute to functional limitations and decreased health-related quality of life (HRQL), pulmonary rehabilitation continues to focus mainly on physical training (ie, aerobic and strength exercises). An integrated cognitive and physical training program compared to physical training alone may be more effective in increasing dual-tasking ability among people living with COPD, leading to greater improvements in performance of ADLs and HRQL.

OBJECTIVE

The aims of this study are to evaluate the feasibility of an 8-week randomized controlled trial of home-based, cognitive-physical training versus physical training for patients with moderate to severe COPD and derive preliminary estimates of cognitive-physical training intervention efficacy on measures of physical and cognitive function, dual task performance, ADLs, and HRQL.

METHODS

A total of 24 participants with moderate to severe COPD will be recruited and randomized into cognitive-physical training or physical training. All participants will be prescribed an individualized home physical exercise program comprising 5 days of moderate-intensity aerobic exercise (30-50 minutes/session) and 2 days of whole-body strength training per week. The cognitive-physical training group will also perform cognitive training for approximately 60 minutes, 5 days per week via the BrainHQ platform (Posit Science Corporation). Participants will meet once weekly with an exercise professional (via videoconference) who will provide support by reviewing the progression of their training and addressing any queries. Feasibility will be assessed through the recruitment rate, program adherence, satisfaction, attrition, and safety. The intervention efficacy regarding dual task performance, physical function, ADLs, and HRQL will be evaluated at baseline and at 4 and 8 weeks. Descriptive statistics will be used to summarize intervention feasibility. Paired 2-tailed t tests and 2-tailed t tests will be used to compare the changes in the outcome measures over the 8-week study period within and between the 2 randomized groups, respectively.

RESULTS

Enrollment started in January 2022. It is estimated that the enrollment period will be 24 months long, with data collection to be completed by December 2023.

CONCLUSIONS

A supervised home-based cognitive-physical training program may be an accessible intervention to improve dual-tasking ability in people living with COPD. Evaluating the feasibility and effect estimates is a critical first step to inform future clinical trials evaluating this approach and its effects on physical and cognitive function, ADL performance, and HRQL.

Relationship between patient functionality impairment and caregiver burden: is there a cut off point for the severe COPD patient?

BACKGROUND

Chronic obstructive pulmonary disease (COPD) patients experience a progressive limitation of their functionality accompanying their clinical evolution. Concretely, severe COPD patients usually require the figure of a caregiver. Caregiver burden has yet to be explored in other similar chronic diseases. The objective is to propose a cutoff point in different functional impairment aspects, to predict the presence of caregiver burden.

METHODS

Severe COPD patients were divided into two groups according to the caregiver burden, measured with the Zarit Burden Interview (ZBI). The patients were assessed with the London Chest Activity of Daily Living (LCADL) scale, the Functional Independence Measure (FIM), and the World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0).

RESULTS

70 COPD patients and their caregivers were included in this cross-sectional study. The ROC curve indicated a cutoff point of 19 in the LCADL scale (AUC = 0.722). Dependence in daily life activities had a cutoff point of 123 in the FIM (AUC = 0.776). Social participation in activities of daily living had a cutoff point of 37 in the WHODAS 2.0 (AUC = 0.739).

CONCLUSION

Dyspnea related to functional status, dependence in daily life activities, and social participation in activities of daily living of severe COPD patients can predict caretaker burden.

Effectiveness and Safety of Multicomponent Physical Training in Patients With Chronic Obstructive Pulmonary Disease: Protocol for a Randomized Clinical Trial

Background

Currently, most Pulmonary Rehabilitation (PR) programs work with conventional physical training, using resources that are not available in public health in Brazil. Multicomponent physical training is a strategy that uses few resources and can reach a larger portion of the population.

Objective

To investigate the effectiveness and safety of multicomponent physical training on physical-functional performance in patients with COPD.

Design

Protocol for a randomized clinical trial with 2 groups in parallel (1:1).

Setting

University-based, outpatient, physiotherapy clinic.

Participants

64 patients aged ⩾50 years, clinical-functional diagnosis of COPD, GOLD II and III criteria will participate in the study.

Intervention

Participants will be randomly allocated into 2 groups: Multicomponent Physical Training-MPT (n = 32): aerobic, strength, balance and flexibility exercises performed in a circuit training format, or Conventional Physical Training-CPT (n = 32): aerobic and strength training. The interventions will be carried out twice a week, for 8 weeks and supervised by the same physiotherapist.

Measurements

The 3 primary outcomes are the 6-Minute Walk Test (6MWT), the 6-Minute Step Test (6MST) and VO₂ consumption as measured during the 6MWT. Secondary outcomes will be exercise capacity, level of physical activity in daily life, peripheral muscle strength, functional status, dyspnea, fatigue and quality of life. Safety will be assessed by recording adverse effects. These outcomes will be evaluated before and after the intervention and the evaluator will be blind.

Limitations

It will not be possible to perform the blinding of the physiotherapist who will supervise the interventions.

Conclusions

This study is expected to demonstrate that MPT using simple resources is an effective and safe intervention for the improvement of the aforementioned outcomes and, in addition, to broaden the horizon of research in relation to new methods of physical rehabilitation for patients with COPD.

SN, P. S, S. S. Effectiveness of upper limb endurance and resistance exercises on reducing dyspnoea and improving activities of daily living (ADL) in patients with COPD

Introduction and Aim: Chronic Obstructive Pulmonary Disease (COPD) is preventable and treatable disease, presenting permanent airflow limitation accompanying an augmented chronic inflammatory response in the airway and the lungs to harmful elements or gases. Chronic bronchitis and emphysema are the two most common conditions that contribute to COPD, individuals with COPD often experience difficulty with performing upper limb exercise due to dyspnoea and arm fatigue. Consequently, upper limb exercise training is habitually included in lung rehabilitation programmes to advance upper limb exercise tolerance; yet the effects of this exercise on dyspnoea and activities of daily living remain unclear. The aim of this analysis is to determine the effects of upper limb endurance and resistance exercises on reducing dyspnoea and improving activities of daily living (ADL) in patients with COPD. Methodology: This is an experimental study design and was conducted in a clinical set-up of Physiotherapy Department with a total number of 10 samples selected based on the Inclusion and Exclusion criteria. All the participants underwent endurance and resistance exercises to the upper limb for 20 Minutes session for 3 days per week for 4weeks. Pre- and post-treatment assessments were done using the outcome measures Modified Borg Scale and London Chest Activity of Daily Living Scale.  Results: The findings of the study revealed improved clinical outcomes in the study group. Calculation of mean and median values and then performing a paired t test of within group between pre-test and post-test values, it shows highly significant difference with a p value of p < 0.001.  Conclusion: This study shows that there is a significant improvement in the COPD patients after the treatment implying that Upper Limb Endurance and Resistance Exercises were beneficial in improving ADL and reducing dyspnoea in COPD patients. Future research suggests recommendation of early COPD treatment in both genders.

Systematic Review of Physical Activity, Sedentary Behaviour and Sleep Among Adults Living with Chronic Respiratory Disease in Low- and Middle-Income Countries

Abstract

Physical activity (PA), sedentary behaviour (SB) and sleep are important lifestyle behaviours associated with chronic respiratory disease (CRD) morbidity and mortality. These behaviours need to be understood in low- and middle-income countries (LMIC) to develop appropriate interventions.

Purpose

Where and how have free-living PA, SB and sleep data been collected for adults living with CRD in LMIC? What are the free-living PA, SB and sleep levels of adults living with CRD?

Patients and Methods

The literature on free-living PA, SB and sleep of people living with CRD in LMIC was systematically reviewed in five relevant scientific databases. The review included empirical studies conducted in LMIC, reported in any language. Reviewers screened the articles and extracted data on prevalence, levels and measurement approach of PA, SB and sleep using a standardised form. Quality of reporting was assessed using bespoke criteria.

Results

Of 89 articles, most were conducted in Brazil (n=43). PA was the commonest behaviour measured (n=66). Questionnaires (n=52) were more commonly used to measure physical behaviours than device-based (n=37) methods. International Physical Activity Questionnaire was the commonest for measuring PA/SB (n=11). For sleep, most studies used Pittsburgh Sleep Quality Index (n=18). The most common ways of reporting were steps per day (n=21), energy expenditure (n=21), sedentary time (n=16), standing time (n=13), sitting time (n=11), lying time (n=10) and overall sleep quality (n=32). Studies revealed low PA levels [steps per day (range 2669-7490steps/day)], sedentary lifestyles [sitting time (range 283-418min/day); standing time (range 139-270min/day); lying time (range 76-119min/day)] and poor sleep quality (range 33-100%) among adults with CRD in LMIC.

Conclusion

Data support low PA levels, sedentary lifestyles and poor sleep among people in LMIC living with CRDs. More studies are needed in more diverse populations and would benefit from a harmonised approach to data collection for international comparisons.

Quantifying the Effect of Monitor Wear Time and Monitor Type on the Estimate of Sedentary Time in People with COPD: Systematic Review and Meta-Analysis

In studies that have reported device-based measures of sedentary time (ST) in people with chronic obstructive pulmonary disease (COPD), we explored if the monitor type and monitor wear time moderated the estimate of this measure. Five electronic databases were searched in January 2021. Studies were included if >70% of participants had stable COPD, and measures of ST (min/day) were collected using wearable technology. Meta-regression was used to examine the influence of moderators on ST, monitor type, and wear time. The studies identified were a total of 1153, and 36 had usable data for meta-analyses. The overall pooled estimate of ST (mean [95% CI]) was 524 min/day [482 to 566] with moderate heterogeneity among effect sizes (I2 = 42%). Monitor wear time, as well as the interaction of monitor wear time and monitor type, were moderators of ST (p < 0.001). The largest difference (−318 min; 95% CI [−212 to −424]) was seen between studies where participants wore a device without a thigh inclinometer for 24 h (and removed sleep during analysis) (675 min, 95% CI [589 to 752]) and studies where participants wore a device with a thigh inclinometer for 12 h only (356 min; 95% CI [284 to 430]). In people with COPD, the monitor wear time and the interaction of the monitor wear time and the monitor type moderated the estimate of ST.

Development Technologies for the Monitoring of Six-Minute Walk Test: A Systematic Review

In the pandemic time, the monitoring of the progression of some diseases is affected and rehabilitation is more complicated. Remote monitoring may help solve this problem using mobile devices that embed low-cost sensors, which can help measure different physical parameters. Many tests can be applied remotely, one of which is the six-minute walk test (6MWT). The 6MWT is a sub-maximal exercise test that assesses aerobic capacity and endurance, allowing early detection of emerging medical conditions with changes. This paper presents a systematic review of the use of sensors to measure the different physical parameters during the performance of 6MWT, focusing on various diseases, sensors, and implemented methodologies. It was performed with the PRISMA methodology, where the search was conducted in different databases, including IEEE Xplore, ACM Digital Library, ScienceDirect, and PubMed Central. After filtering the papers related to 6MWT and sensors, we selected 31 papers that were analyzed in more detail. Our analysis discovered that the measurements of 6MWT are primarily performed with inertial and magnetic sensors. Likewise, most research studies related to this test focus on multiple sclerosis and pulmonary diseases.

Multi-Dimensional Dyspnea-Related Scales Validated in Individuals With Cardio-Respiratory and Cancer Diseases. A Systematic Review of Psychometric Properties

CONTEXT

In order to examine the multi-dimensional nature of dyspnea and its impact on the activities of daily living (ADLs) in patients with cardio-respiratory and cancer diseases, validated measures are needed.

OBJECTIVES

Our aim was to identify all the multi-dimensional clinical scales assessing dyspnea and its impact on ADLs in patients with cardio-respiratory and cancer diseases, and to critically appraise their psychometric properties.

METHODS

Five databases were systematically searched up to July 2020. Eligible criteria were: the examination of at least one psychometric property, and the recruitment of adults with a cardio-respiratory or cancer disease in non-emergency settings. The characteristics and psychometric properties of the studies included were presented through a narrative synthesis. The methodological quality of the studies and evidence synthesis were rated using the "COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN)" criteria.

RESULTS

Forty-three studies, for which eight assessment scales had been identified, were included in the review. At the time of the review, three multi-dimensional assessment scales were available for assessing dyspnea symptoms, and five multi-dimensional scales were available to examine the impact of dyspnea on ADLs. Although the use of these scales has rapidly grown, evidence of psychometric properties has been reported as limited in most of the scales.

CONCLUSION

Despite the potential of the identified scales, further studies are needed to strength evidence on the validity and reliability of the multi-dimensional dyspnea scales. Furthermore, more studies appraising the content validity and responsiveness of the scales are specifically recommended.

Modified Medical Research Council and COPD Assessment Test Cutoff Points

BACKGROUND

The modified Medical Research Council (mMRC) and COPD Assessment Test (CAT) are assessment instruments associated with level of physical activity of daily living (PADL) in patients with COPD. This study aimed to identify mMRC and CAT cutoff points to discriminate sedentary behavior and PADL level of subjects with COPD and verify whether these cutoff points differentiate pulmonary function, health-related quality of life (HRQOL), functional status, and mortality index in subjects with COPD.

METHODS

Subjects (N = 131, FEV₁: 36.7 ± 16.1% predicted) were assessed for lung function, mMRC, CAT, HRQOL, functional status, and mortality index. PADL was monitored using a triaxial accelerometer, and subjects were classified as sedentary/nonsedentary (cutoff point of 8.5 h/d in PADL < 1.5 metabolic equivalent of task [MET]), physically active/inactive (cutoff point of 80 min/d in PADL ≥ 3 METs), and with/without severe physical inactivity (cutoff point of 4,580 steps/d), according to variables provided by accelerometer.

RESULTS

ROC curve indicated mMRC cutoff point of ≥ 2 (P < .05) for physical inactivity (sensitivity = 66%, specificity = 56%, AUC = 0.62), severe physical inactivity (sensitivity = 81%, specificity = 66%, AUC = 0.76), and sedentary behavior (sensitivity = 61%, specificity = 70%, AUC = 0.65). The identified CAT cutoff points were ≥ 16 and ≥ 20, considering severe physical inactivity (sensitivity = 76%, specificity = 54%, AUC = 0.69, P < .001) and sedentary behavior (sensitivity = 51%, specificity = 90%, AUC = 0.71, P = .001), respectively. Subjects who had mMRC ≥ 2 and CAT ≥ 16 or ≥ 20 presented worse pulmonary function, HRQOL, functional status, and mortality index compared with those who scored mMRC < 2 and CAT <16 or < 20.

CONCLUSIONS

mMRC cutoff point of ≥ 2 is recommended to discriminate PADL level and sedentary behavior, whereas CAT cutoff points of ≥ 16 and ≥ 20 discriminated severe physical inactivity and sedentary behavior, respectively. These cutoff points differentiated subjects with COPD regarding all the outcomes assessed in this study.

Clinical efficacy of glucocorticoid and terbutaline in the treatment of acute exacerbation of chronic obstructive pulmonary disease

BACKGROUND

To investigate the efficacy of glucocorticoid and terbutaline in the treatment of acute exacerbation of chronic obstructive pulmonary disease (AECOPD).

METHODS

248 patients with AECOPD were assigned into two groups, 124 patients in the control group were only given terbutaline treatment, while 124 patients in the experimental group were treated with glucocorticoid and terbutaline. The effect on lung function and blood gas indexes were compared between the two groups.

RESULTS

The total effective rate of the treatment with glucocorticoid and terbutaline was higher than that of control group (P < 0.05). After treatment, the pulmonary function indexes such as FEV₁, FVC and PaO₂ levels in the two groups were significantly higher than those before treatment, PaCO₂ levels were significantly lower than that before the treatment (P < 0.05).

CONCLUSIONS

The combined use of glucocorticoid and terbutaline could effectively improve the lung function and blood gas indexes. It's of great significance to promote the rehabilitation of patients with AECOPD, and it provides insights for future clinical practice.

The Investigation of Falls and Balance from the Perspective of Activities of Daily Living in Patients with COPD

The aim of this study was (1) to compare the activities of daily living (ADLs), perceived falling risk and balance in chronic obstructive pulmonary disease (COPD) patients with or without falling history and (2) to investigate the relationship between ADLs and balance. Fourteen patients with COPD with a history of falling whose mean falling frequency was 2.64 ± 0.74 times in the last 12-months (fallers) and 14 age and sex-matched patients with COPD with no history of falling (non-fallers) were included. The outcome measures were the London Chest Activity of Daily Living (LCADL) scale, Activities-Specific Balance Confidence (ABC) scale, Berg Balance Scale (BBS), 6-minute walking test, and quadriceps-femoris strength. Fallers reported increased dyspnoea perception in ADLs, decreased balance confidence, and disturbed balance compared with non-fallers (p < 0.05). A strong correlation was found between the LCADL scale item score (dressing the upper body) and the BBS total score (rho = -0.81, p = 0.001) in fallers. The LCADL scale item score (going out socially) was significantly correlated with the total score of the ABC scale (rho = -0.61, p = 0.001). Moderate correlations were found between the LCADL scale item scores (dressing the upper body, washing hair, and walking up stairs) and the BBS total score (p < 0.003). This study demonstrated that increased severity of dyspnoea perception during ADLs is associated with impaired balance and poor balance confidence, regardless of functional capacity and peripheral muscle strength in patients with COPD. The balance confidence was low in functional mobility-based activities in patients with COPD with a history of falling.
