To translate the English version of the London Chest Activity of Daily Living scale (LCADL) into a Korean version and to determine the reliability and validity of the Korean version in patients with chronic obstructive pulmonary disease (COPD).
The English version of LCADL was translated into Korean and back-translated into English. Subsequently, the back-translated version was reviewed and compared with the original, and thus the final K-LCADL was obtained. To evaluate the validation of the K-LCADL, patients simultaneously completed a pulmonary function test, a 6-Minute Walk Test (6MWT), and questionnaires, including the modified Medical Research Council (mMRC) dyspnea scale, the Korean version of the St. George's Respiratory Questionnaire (K-SGRQ), the Korean version of the COPD Assessment Test (K-CAT), and the Korean version of the EuroQoL-5 Dimensions (K-EQ-5D). To assess test-retest reliability, the K-LCADL was again administered to the same patients within 2 weeks from initial assessment.
A total of 94 patients participated in the present study. The total K-LCADL score was positively correlated with the K-SGRQ (r=0.802, p<0.001), the mMRC dyspnea scale (r=0.603, p<0.001), and the K-CAT score (r=0.714, p<0.001), and negatively correlated with the K-EQ-5D (r=−0.764, p<0.001), 6MWT (r=−0.635, p<0.001), forced expiratory volume in one second 1 (r=−0.416, p=0.002), and forced vital capacity (r=−0.397, p=0.023). Intraclass correlation coefficient of the K-LCADL was 0.951 (p<0.001).
The K-LCADL is a reliable and valid questionnaire for evaluating limitation of activities of daily living in patients with COPD.

To compare the respiratory muscle strength between patients with stable and acutely exacerbated (AE) chronic obstructive pulmonary disease (COPD) at various stages.
A retrospective medical record review was conducted on patients with COPD from March 2014 to May 2016. Patients were subdivided into COPD stages 1–4 according to the Global Initiative for Chronic Obstructive Lung Disease guidelines: mild, moderate, severe, and very severe. A rehabilitation physician reviewed their medical records and initial assessment, including spirometry, maximum inspiratory pressure (MIP), maximum expiratory pressure (MEP), COPD Assessment Test, and modified Medical Research Council scale. We then compared the initial parameters in patients with a stable condition and those at AE status.
The AE group (n=94) had significantly lower MIP (AE, 55.93±20.57; stable, 67.88±24.96; p=0.006) and MIP% (AE, 82.82±27.92; stable, 96.64±30.46; p=0.015) than the stable patient group (n=36). MIP, but not MEP, was proportional to disease severity in patients with AE and stable COPD.
The strength of the inspiratory muscles may better reflect severity of disease when compared to that of expiratory muscles.

Objective: To evaluate the effectiveness of a short-term inpatient pulmonary rehabilitation treatment program including inspiratory muscle training and reconditioning exercise in pneumoconiosis patients.
Method: Thirty pneumoconiosis patients have undergone a 3-week inpatient pulmonary rehabilitation program. The program included a inspiratory muscle strengthening, relaxation technique and reconditioning exercise such as walking and upper extremity strengthening. The effectiveness of treatment was evaluated by a pulmonary function test, 6-minute walk distance and 150 mm-visual analog dyspnea scale before and after the program.
Results: After the 3-week inpatient pulmonary rehabilitation program, there was a significant increase in 6-minute walk distance(p＜0.01) and a significant decrease in 150 mm-visual analog dyspnea scale(p＜0.01). However the pulmonary function test showed no significant change.
Conclusion: We concluded that the short-term inpatient pulmonary rehabilitation program can improve the exercise tolerance by reduction of dyspnea and increase of walk distance, and ultimately increase the quality of life in pneumoconiosis patients.
