title: Applicability of the London Chest Activity of Daily Living scale in patients on the waiting list for lung transplantation.
abstract: OBJECTIVE
  To evaluate the applicability of the London Chest Activity of Daily Living (LCADL) scale in patients on the waiting list for lung transplantation.
  
  
  METHODS
  This was a cross-sectional study, conducted between May and September of 2010, involving 26 male and female patients on the waiting list for lung transplantation and treated at the Pulmonary Rehabilitation Program in the Complexo Hospitalar Santa Casa de Misericórdia de Porto Alegre, located in the city of Porto Alegre, Brazil. We evaluated the patients using the six-minute walk test (6MWT) and pulmonary function tests. We also obtained the LCADL scores, as well as the modified Borg scale scores for sensation of dyspnea and leg fatigue. Cronbach's alpha coefficient was used to determine the internal consistency of the LCADL scale. Linear regression analysis was used in order to identify associations between the total LCADL score (expressed as a percentage) and the variables studied.
  
  
  RESULTS
  According to the LCADL scale results, 69% of the patients reported that the performance of their activities of daily living was significantly impaired by their dyspnea. The internal consistency of the LCADL scale was 0.89. After adjusting for age and FEV1, we found that the total LCADL scale score showed statistically significant negative associations with the six-minute walk distance (β = -0.087; p < 0.001) and the six-minute walk work (β = -0.285; p < 0.001).
  
  
  CONCLUSIONS
  Our findings suggest that the LCADL scale is a useful tool for assessing patients on the waiting list for lung transplantation.
