Abstract

Purpose: This study aimed to develop a linguistically validated Japanese translation of the multidimensional dyspnea profile (MDP) and assess whether worsening of dyspnea's sensory and affective domains during exercise had detrimental effects on physical activity in stable outpatients with chronic obstructive pulmonary disease (COPD).

Materials and methods: The Japanese version of the MDP was prepared in collaboration with Mapi Research Trust (Lyon, France) after the approval of the developer. Physical activity was assessed using a 3-axis accelerometer. Dyspnea upon exertion was investigated using a 3-minute step test.

Results: The Japanese version of the MDP was obtained and validated linguistically. Air-hunger was significantly associated with total calories from walking (r = - 0.47, p < 0.05), while anxiety and depression were significantly correlated with both the amount and intensity of physical activity (r = - 0.49, p < 0.05, and r = - 0.46, p < 0.05, respectively).

Conclusion: The Japanese version of the MDP was suggested to reflect both pulmonary functions, ventilatory response during exercise, and intensity and amount of physical activity in patients with COPD.

Keywords: chronic obstructive pulmonary disease; dyspnea; multidimension; physical activity.
