Effects of Inspiratory Muscle Training on Dyspnea in Subjects With Chronic Obstructive Pulmonary Disease (IMT)

November 26, 2025 updated by: University Hospital, Brest

Effects of Inspiratory Muscle Training Combined With a Pulmonary Rehabilitation Program Versus a Program of Pulmonary Rehabilitation Alone on Dyspnea: a Randomized Trial

The purpose of this study is to determinate whether inspiratory muscle training (IMT) associated with a conventional respiratory rehabilitation program is more effective than a conventional respiratory rehabilitation program alone,on Dyspnea in chronic obstructive pulmonary disease (COPD) subjects with a normal maximum inspiratory pressure (IP > 60 cmH2O).

Detailed Description

Dyspnea is the main complaint of patients with COPD. Dyspnea is explained largely by the distension, objectified by measuring inspiratory capacity (IC), which places the diaphragm at a disadvantage to be effective, which raises the sensation of dyspnea.

Currently, inspiratory muscles training is recommended by the French-language Society of Pneumology, in case of an objective reduction of the strength of these muscles (corresponding to maximum inspiratory pressure <60 cm H20).
