Summary

Comparable RCTs of clinical therapeutic effects using respiratory physiology-oriented IMT device in different operation principle in COPD are so far lacking. Therefore the investigators perform an adequately powered RCT on the effects of two IMT device application as an pulmonary physical therapy in patients with COPD with inspiratory muscle weakness.

Conditions

Interventions

DEVICE

Threshold inspiratory muscle training

Threshold inspiratory muscle training device (Threshold Inspiration Muscle Trainer, Respironics Inc; Pittsburgh, Pennsylvania, USA). The intensiy of IMT was adjusted and verification using Pm measurement in laboratory. Patients spontaneously breathed using resistive-IMT and their Pm were measured simultaneously. Adjusted the intensity of resistive-IMT from small to large according to the Pm waveform. Adjustment completed while mean Pm achieved 60% of MIP and maintained at least 15 minute. Likewise, eligible patients in these group used the resistive IMT device for 15 minutes, twice per day, with an inspiratory load at 60% of PImax as previously adjustment. Training loads were adjusted to maintain 60% of the PImax every week.

DEVICE

Resistive inspiratory muscle training

Resistive inspiratory muscle training device(PFLEX, Respironics Inc; Pittsburgh, Pennsylvania, USA). The intensiy of IMT was adjusted and verification using Pm measurement in laboratory. Patients spontaneously breathed using resistive-IMT and their Pm were measured simultaneously. Adjusted the intensity of resistive-IMT from small to large according to the Pm waveform. Adjustment completed while mean Pm achieved 60% of MIP and maintained at least 15 minute. Likewise, eligible patients in these group used the resistive IMT device for 15 minutes, twice per day, with an inspiratory load at 60% of PImax as previously adjustment. Training loads were adjusted to maintain 60% of the PImax every week.
