Brief Summary

Chronic obstructive pulmonary disease (COPD) is characterised by non-reversible bronchial obstruction associated with systemic disorders and comorbid factors. Dyspnoea is a common symptom among patients with Chronic Obstructive pulmonary Disease (COPD). Dyspnea is the primary symptom limiting exercise and daily activities in these patients. It has been reported that breathing cold air could decrease dyspnoea induced by exercise and could improve exercise performance. The aim of this study is to carry out the effect of cooling sensation induced by menthol chewing-gum on dyspnoea and exercise performance among patients with COPD.

Primary Outcome Measures
NameTimeMethod
Change in Dyspnea after each testsThe outcome will be measured before and at the end of the test, the two six-minute walk test will perform the same day, separate from 30 minutes minimum for a total time frame of 1 day.

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

Secondary Outcome Measures
NameTimeMethod
Change in respiratory rateData will be continuously collected during every tests. The two six-minute walk test will perform the same day, separate from 30 minutes minimum for a total time frame of 1 day.

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

Change in tidal volumeThe outcome will be measured before and at the end of the test, the two six-minute walk test will perform the same day, separate from 30 minutes minimum for a total time frame of 1 day.

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

Change in inspiratory capacityThe outcome will be measured before and at the end of the test, the two six-minute walk test will perform the same day, separate from 30 minutes minimum for a total time frame of 1 day.

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

Change in Oxygen SaturationData will be continuously collected during every tests. The two six-minute walk test will perform the same day, separate from 30 minutes minimum for a total time frame of 1 day.

Change in Oxygen Saturation (%) using a pulse oximetry

Change in Cardiac FrequencyData will be continuously collected during every tests. The two six-minute walk test will perform the same day, separate from 30 minutes minimum for a total time frame of 1 day.

Change in Cardiac Frequence (bpm) using a pulse oximetry

Change in 6-min walk distanceThe outcome will be measured at the end of each tests. The two six-minute walk test will perform the same day, separate from 30 minutes minimum for a total time frame of 1 day.

Change in 6-min walk distance (meters).
