Energy Conservation Technique in COPD Patients

Chronic obstructive pulmonary disease (COPD) is characterised by non-reversible bronchial obstruction associated with systemic disorders and comorbid factors. Dynamic hyperinflation during an exercise increase dyspnea and can reduce exercise capacity. Stair climbing is associated with prolonged dynamic hyperinflation and severe dyspnea in COPD patients. The aim of this study is to carry out the effect of an energy conservation technique on dyspnea to facilitate stair climbing.

Treatment and study plan

Energy Conservation Technique

Other

During the session of stair climbing, patients will perform a break at least of 5 seconds every 3 steps.

Control Session

Other

Patients will realize one session of stair climbing at their own pace

Primary outcomes

  1. Difference in Dyspnea at iso time and at time limit between the two sessions

    Time frame: The outcome will be measured before, at the end and every one minute during the stair climbing sessions. The two stair climbing sessions will perform the same day, separate from 30 minutes minimum for a total time frame of 1 day.

    Difference in dyspnea using Modified Borg Scale (0 - 10 points) 0=no dyspnea ; 10 = maximal effort

Secondary outcomes

  1. difference in time required for the patient to climb the 6 floors

    Time frame: The outcome will be collected at the end of each sessions. The two stair climbing sessions will perform the same day, separate from 30 minutes minimum for a total time frame of 1 day.

    Difference in time (seconds) will be evaluated using a stopwatch

  2. Difference in respiratory rate

    Time frame: Data will be continuously collected during every sessions. The two stair climbing sessions will perform the same day, separate from 30 minutes minimum for a total time frame of 1 day.

    Difference in respiratory rate (cycles per minute) will be measured breath-by-breath using a Respiratory Inductive Plethysmography

  3. Difference in inspiratory capacity

    Time frame: The outcome will be collected before and at the end of each sessions (within 2 minutes after the end). The two stair climbing sessions will perform the same day, separate from 30 minutes minimum for a total time frame of 1 day.

    Difference in inspiratory capacity (Liters) will be measured using a portable spirometer

  4. Difference in Cardiac Frequency

    Time frame: Data will be continuously collected during every sessions. The two stair climbing sessions will perform the same day, separate from 30 minutes minimum for a total time frame of 1 day.

    Difference in Cardiac Frequence (bpm) using a pulse oximetry

  5. Difference in Oxygen Saturation

    Time frame: Data will be continuously collected during every sessions. The two stair climbing sessions will perform the same day, separate from 30 minutes minimum for a total time frame of 1 day.

    Difference in Oxygen Saturation

  6. Difference in peripheral muscle oxygenation

    Time frame: Data will be continuously collected during every sessions. The two stair climbing sessions will perform the same day, separate from 30 minutes minimum for a total time frame of 1 day.

    Muscle oxygenation (arbitrary unit) will be evaluated using Near-infrared spectroscopy technology.

  7. Difference in tidal volume

    Time frame: The outcome will be collected before and at the end of each sessions (within 2 minutes after the end). The two stair climbing sessions will perform the same day, separate from 30 minutes minimum for a total time frame of 1 day.

    Difference in tidal volume (Liters) will be measured breath-by-breath using a portable spirometer

  8. Difference in muscular fatigue

    Time frame: The outcome will be measured before, at the end and every one minute during the stair climbing sessions. The two stair climbing sessions will perform the same day, separate from 30 minutes minimum for a total time frame of 1 day.

    Difference in muscular fatigue using Modified Borg Scale (0 - 10 points) 0=no muscular fatigue ; 10 = maximal effort
