Impact of aerobic exercise, either associated or not with NIV, by two positive pressure levels on COPD patient functionality. [ Time Frame: 6 weeks ] [ Designated as safety issue: No ]
It was measured by means of step-climbing repetitions and distance covered in the six-minute walk test as well as the CPT.

  • Change in oxygen consumption. [ Time Frame: 6 weeks ] [ Designated as safety issue: No ]
    It was evaluated through a MedGraphics VO2000 metabolic system which was operated via computer with Aerograph software and store the signals with the 20-second method at the peak of each activity in the set of ADLs and in the peak of CPT.
  • Change in metabolic rate. [ Time Frame: 6 weeks. ] [ Designated as safety issue: No ]
    It was evaluated through a MedGraphics VO2000 metabolic system which was operated via computer with Aerograph software and store the signals with the 20-second method at the peak of each activity in the set of ADLs and in the peak of CPT.
  • Change in oxygenation. [ Time Frame: 6 weeks. ] [ Designated as safety issue: No ]
    It was evaluated through a Dixtal® wrist oxymeter at the peak of each activity in the set of ADLs and in the peak of CPT.
  • Change in sensation of dyspnea. [ Time Frame: 6 weeks ] [ Designated as safety issue: No ]
    It was evaluated through a modified Borg scale at the peak of each activity in the set of ADLs and in the peak of CPT.
  • Change in quality of life. [ Time Frame: 6 weeks. ] [ Designated as safety issue: No ]
    It was evaluated through the SF-36 (domains: physical functioning, role-physical, and vitality).

Noninvasive Ventilation on Chronic Obstructive Pulmonary Disease (COPD) Patient Functionality
Impact of Aerobic Physical Training Associated With Noninvasive Ventilation on COPD Patient Functionality - A Controlled Randomized Study

On the following tests, there would be a greater increase in the functionality of COPD patients who underwent combined therapy than in those who only exercised: a set of activities of daily living (ADLs), the six-minute walk test (6MWT), an incremental symptom-limited cardiopulmonary test (CPT), and the physical functioning scale of the Short-Form 36 quality of life questionnaire (SF-36).

Impact of aerobic exercise plus noninvasive ventilation (NIV) on the functionality of patients with COPD. Thirty patients (70.5 - 8.5 years) with COPD (forced expiratory volume in the first second 48.5 - 15.4% of predicted) were randomized into either a physical training group involving aerobic treadmill exercise (PTG, n=12) or an exercise plus bilevel ventilation group (PTGNIV, n=11) with sessions three times a week for six weeks.

Allocation: Randomized
Endpoint Classification: Efficacy Study
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Treatment
Chronic Obstructive Pulmonary Disease (COPD)
Other: physical training
For both groups, the approximately hour-long sessions occurred three times a week on alternate days for six consecutive weeks (18 sessions). Each session began with five minutes of stretching that included the cervical muscles and the upper and lower limbs, which was followed by five minutes of warm-up on a treadmill at 2Km/h and 30 minutes of aerobic physical training at a constant 3% incline.
Other Names:
  • TFG: physical training group
  • PTGNIV: exercise plus bilevel ventilation group
  • Experimental: Physical Training Group
    This group performed aerobic physical training in treadmill.
    Intervention: Other: physical training
  • Experimental: NIV Trained

    This group performed aerobic physical training associated with ventilation in the bilevel modality (BiPAP®), using a nasal mask as an interface.

    On evaluation day, the levels of inspiratory positive airway pressure (IPAP) (between 10 and 15cmH2O) and expiratory positive airway pressure (EPAP) (between 4 and 6cmH2O) were defined, varying according to the comfort level of each patient.

    Intervention: Other: physical training
