NCT01449643

Brief Summary

The purpose of this study is whether an inspiratory muscle training protocol would be associated with an improvement in of the diaphragm mobility, an increase in pulmonary function values , gain strength and endurance of respiratory muscles and improving quality of life.

Outcome Measures

Primary Outcomes (1)

  • Ultrasound evaluation of the diaphragm mobility

    Compare and correlate diapgragm excursion with pulmonary function.

    3 months

Secondary Outcomes (1)

  • Pulmonary function test

    3 months

Study Arms (2)

IMT Group

ACTIVE COMPARATOR

Threshold IMT provides consistent and specific pressure for inspiratory muscle strength and endurance training, regardless of how quickly or slowly patients breathe. This device incorporates a flow-independent one-way valve to ensure consistent resistance and features an adjustable specific pressure setting (in cm H20). When patients inhale through Threshold IMT, a spring-loaded valve provides a resistance that exercises respiratory muscles through conditioning.
