ABSTRACT
As a simple, objective, effective, and repeatable functional testing method, six-minute walk test(6 MWT) was widely used in the physical assessment of patients with chronic cardiopulmonary diseases. The correct evaluation of cardiopulmonary function of patients with occupational pneumoconiosis(hereinafter referred to as pneumoconiosis) has important reference value for their cardiopulmonary rehabilitation. The application of 6 MWT in the cardiopulmonary function rehabilitation of pneumoconiosis patients mainly includes the following: it can accurately evaluate the maximum physical load of pneumoconiosis patients during exercise; comprehensively evaluate the cardiopulmonary function of pneumoconiosis patients, guide the formulation of personalized exercise prescription and improve the practicability of exercise prescription; evaluate the safety of exercise in pneumoconiosis patients; evaluate the effect of exercise rehabilitation; and pre-evaluate the cardiopulmonary function. As a supplement to cardiopulmonary exercise test, it can be used in disability identification of pneumoconiosis patients.The 6 MWT can provide a quantitative index for the assessment of cardiopulmonary function in pneumoconiosis patients, and it is worthy of wide application in the assessment of cardiopulmonary function, exercise ability and respiratory rehabilitation in such patients.
