NCT01056081

Brief Summary

Uncertainty persists regarding the usefulness of incorporating inspiratory muscle training (IMT) in pulmonary rehabilitation programs for patients with chronic obstructive pulmonary disease. In this study the investigators investigate whether IMT associated with exercise training would be better than exercise training alone, with regard to exercise capacity, inspiratory muscle strength and dyspnea.

Study Arms (1)

Inspiratory muscle training

EXPERIMENTAL

The training was performed using a threshold inspiratory muscle trainer (Respironics HealthScan, Inc, Cedar Grove, New York, USA). The patients performed the IMT training in a seated position, with the upper limbs supported. The total duration of the respiratory training was 30 minutes, with sequences of three minutes of training followed by pauses of two minutes. The initial load was equivalent to 30% of the individual's MIP. This load was progressively increased over the first four weeks, according to the patients' tolerance, to reach 60% of the MIP. This level was then maintained until the end of the training.
