Further study details as provided by University of Florida:

Primary Outcome Measures:
  • VT/FVC [ Time Frame: 3 months ] [ Designated as safety issue: No ]
    The primary endpoints for inspiratory muscle training efficacy will include respiratory muscle strength.

Secondary Outcome Measures:
  • VT/FVC [ Time Frame: 3 months ] [ Designated as safety issue: No ]
    Secondary outcome measures include respiratory function and breathing pattern during loaded breathing

Estimated Enrollment: 30
Study Start Date: April 2011
Estimated Study Completion Date: December 2016
Estimated Primary Completion Date: June 2016 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Exercise Device: Threshold PEP or IMT device Phillips-Respironics
The subject will be instructed to take 8-15 deep, forceful breaths through the Threshold device, followed by at least 3 minutes of rest. The process will be repeated 3 more times for a total of 4 sets of 8-15 breaths. IMST will be completed three to five days per week, based upon the subject's daily baseline level of fatigue.
