Energy Conservation Technique in COPD Patients

Not Applicable

Completed

• Conditions: Chronic Obstructive Pulmonary Disease
• Interventions: Other: energy conservation technique; Other: control session

• Registration Number: NCT03564028
• Lead Sponsor: Groupe Hospitalier du Havre

Brief Summary

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.

Arm && Interventions

Group	Intervention	Description
energy conservation technique	energy conservation technique	Patients will perform one session of stair climbing of 108 steps (corresponding to 6 floors).
Control session	control session	Patients will perform one session of stair climbing of 108 steps (corresponding to 6 floors).

Primary Outcome Measures

Name	Time	Method
Difference in Dyspnea at iso time and at time limit between the two sessions	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 Outcome Measures

Name	Time	Method
difference in time required for the patient to climb the 6 floors	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
Difference in respiratory rate	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
Difference in Cardiac Frequency	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
Difference in inspiratory capacity	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
Difference in Oxygen Saturation	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
Difference in peripheral muscle oxygenation	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.
Difference in muscular fatigue	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
Difference in tidal volume	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
