      Objectives: We aimed to explore physiological responses to the six-minute walk test (6MWT) and assess computed tomographic (CT) features of the lungs and thigh muscle in order to determine contributors to dyspnea intensity ...
    • Emphysema and DLCO predict a clinically important difference for 6MWD decline in COPD 
      Díaz, Alejandro A.; Pinto Plata, Víctor; Hernández, Camila; Peña, Javier; Ramos Gómez, Cristóbal; Díaz, Juan C.; Klaassen, Julieta; Patino, Cecilia M.; Saldías, Fernando; Díaz, Orlando (Elsevier, 2015)
      Background: Exercise impairment is a central feature of chronic obstructive pulmonary disease (COPD), and a minimal clinically important difference (MCID) for 6-min walk distance (6MWD) decline (>30 m) has been associated ...
    • Pedometers to enhance physical activity in COPD: a randomised controlled trial 
      Mendoza Inzunza, Laura; Horta, Paula; Espinoza, José; Aguilera, Miguel; Balmaceda, Nicolás; Castro Lara, Ariel; Ruiz Carmona, Mauricio; Díaz, Orlando; Hopkinson, Nicholas (EUROPEAN RESPIRATORY SOC JOURNALS, 2015)
