The Effect of NIV on QoL and Exercise Capacity in a COPD Exercise Rehabilitation Program


This trial hopes to demonstrate the effect of 4 weeks of outpatient exercise rehabilitation on COPD patients. In particular the effect on:

- the amount of daily physical activity

- Quality of life

- The 6-minute walk distance

- Time to exacerbation

and compare it to the effect of 4 weeks of outpatients rehabilitation with Noninvasive Ventilation as an adjunct therapy.

Study Type

  • Study Type: Interventional
  • Study Design
    • Allocation: Randomized
    • Intervention Model: Parallel Assignment
    • Primary Purpose: Treatment
    • Masking: None (Open Label)
  • Study Primary Completion Date: October 2016


  • Device: BiLevel Noninvasive Ventilation
    • Positive pressure applied through an oro-nasal mask. The pressure is altered between inspiration and expiration.

Arms, Groups and Cohorts

  • No Intervention: Control Arm
    • This arm will perform the pulmonary rehabilitation as specified with no respiratory assistance.
  • Active Comparator: Intervention Arm
    • This arm will conduct the pulmonary rehabilitation program with BiLevel Noninvasive Ventilation assistance from a ResMed ventilator.

Clinical Trial Outcome Measures

Primary Measures

  • Daily Physical Activity
    • Time Frame: 3 Months
    • The primary outcome will be measured by daily activity using accelerometer arm bands. This will be measured at the beginning of the rehabilitation program, at the end and at a 3 month follow up.
  • Exercise Capacity
    • Time Frame: 6 Weeks
    • 6 Minute Walking Distance will be measured every week during the exercise program.

Secondary Measures

  • Quality of Life
    • Time Frame: 3 Months
    • Using the St. George Respiratory Questionnaire before and after rehabilitation, quality of life will be measured.
  • Dyspnoea
    • Time Frame: 6 Weeks
    • Change in Dyspnoea after end of exercise will be assessed using the Multidimensional Dyspnoea Profile and the BORG scale.
  • Change in Physiological Parameters
    • Time Frame: 3 Months
    • Maximum training intensity, body weight and muscle diameter will be tracked throughout the training program.
