“…This result is in concordance with the original LCADL validation study and other cross-cultural validation studies which also showed high test–retest reliability. 7,10–12 The minimal detectable change for LCADL total, self-care, domestic, physical, and leisure score found in the present study were slightly higher than those found in a recent study of Bisca et al 29 Our SDC values were higher which can possibly be explained by the smaller number of patients used in the Bisca et al 29 study which results in larger measurement error. The SDC% for the LCADL total score was lower than the SDC% for the domain scores.…”

“…The instrument is moderately sensitive to measure change after an intervention with improvements exceeding the recently suggested minimal detectable change. 29 The SEM values can be used to assess the relevance of observed changes in individual patients. 42 In addition, since %SDC was lowest for LCADL total, we suggest to use the LCADL total score for individual patients.…”

This study assesses the validity, reliability, and responsiveness of the Dutch version of the London Chest Activity of Daily Living scale (LCADL).The English LCADL version was translated into Dutch and then back-translated to English to check if the translation was conceptually equivalent to the original LCADL.Measurement properties were evaluated in191 patients with chronic obstructive pulmonary disease (COPD) (70 males; age 62 ± 9 years; FEV1 33 ± 10% pred). Construct validity was assessed using disease-specific health status, generic functional status, and functional and peak exercise capacity (Wmax). LCADL was completed twice to assess test–retest reliability. Responsiveness was assessed after 8 to 12 weeks inpatient pulmonary rehabilitation.LCADL correlated significantly with the St. George Respiratory Questionnaire (r = 0.24 to 0.64), functional status (r = 0.45 to 0.82), walking distance (r = −0.3 to −0.58), and Wmax (−0.27 to −0.38) and Wmax % pred (−0.26 to −0.43). Test–retest reliability was high (ICC 0.87 to 0.98). The smallest detectable change for the LCADL total and domain score self-care, domestic, physical, and leisure was 4.5, 2.9, 3.3, 4.9, and 2.2, respectively. Improvement in LCADL after PR correlated significantly with improvement in Chronic Respiratory Questionnaire (−0.43; P < 0.001).The Dutch LCADL is a reliable, valid, and responsive instrument to assess limitations in performing activities of daily living in patients with severe COPD.

“…The total score can range from 0 to 75 points, a higher score translating to greater limitations in ADL. ( 19 ) The minimal detectable change for the LCADL scale score to measure the effect of interventions is of less than 3.88 points ( 20 ) In order to assess submaximal exercise capacity, we used the six-minute walk test (6MWT). The 6MWT is a submaximal test that determines the functional capacity of patients with chronic lung disease, being easy to perform, well tolerated, reproducible, and inexpensive.…”

OBJECTIVE: To evaluate the ability of COPD patients to perform activities of daily living (ADL); to identify barriers that prevent these individuals from performing ADL; and to correlate those barriers with dyspnea severity, six-minute walk test (6MWT), and an ADL limitation score. METHODS: In COPD patients and healthy, age-matched controls, the number of steps, the distance walked, and walking time were recorded with a triaxial accelerometer, for seven consecutive days. A questionnaire regarding perceived barriers and the London Chest Activity of Daily Living (LCADL) scale were used in order to identify the factors that prevent the performance of ADL. The severity of dyspnea was assessed with two scales, whereas submaximal exercise capacity was determined on the basis of the 6MWT. RESULTS: We evaluated 40 COPD patients and 40 controls. In comparison with the control values, the mean walk time was significantly shorter for COPD patients (68.5 ± 25.8 min/day vs. 105.2 ± 49.4 min/day; p < 0.001), as was the distance walked (3.9 ± 1.9 km/day vs. 6.4 ± 3.2 km/day; p < 0.001). The COPD patients also walked fewer steps/day. The most common self-reported barriers to performing ADL were lack of infrastructure, social influences, and lack of willpower. The 6MWT distance correlated with the results obtained with the accelerometer but not with the LCADL scale results. CONCLUSIONS: Patients with COPD are less active than are healthy adults of a comparable age. Physical inactivity and the barriers to performing ADL have immediate implications for clinical practice, calling for early intervention measures.

Objetivos: Realizar uma revisão não sistemática da literatura a fim de explorar os principais instrumentos utilizados para avaliar a limitação funcional de pacientes com DPOC. Métodos: Pesquisou-se nas bases de dados Medline, PubMed e SciELO, usando-se os termos: atividades de vida diária, atividades cotidianas, atividades físicas na vida diária, capacidade funcional e doença pulmonar obstrutiva crônica. Resultados: Os principais instrumentos foram classificados, conforme suas características, em: questionários e escalas, testes clínicos e sensores de movimento. Descreveram-se a escala LCADL e o questionário PFSDQ. Quanto aos testes clínicos são apresentados: TC6min, AVD-Glittre (TGlittre), Sentar e Levantar, Step Chester e GST, além dos sensores de movimento. Conclusões: Na seleção dos instrumentos de avaliação ideais, devem-se considerar ferramentas que possibilitem atingir os aspectos importantes relacionados à doença e ao impacto que esta causa nesses indivíduos. Dentre os instrumentos apresentados, destacam-se LCADL, TC6min, TGlittre e acelerômetros triaxiais.

Minimal Detectable Change of the London Chest Activity of Daily Living Scale in Patients With COPD

Abstract: This study provided the MDC for the domains and total score of the LCADL. A change of 4 points in the total score of the LCADL can be interpreted as a meaningful change.
