Asthma
Conditions
Brief summary
Limitation of activity is one of the main item used by composites scores designed to assess the level of asthma control. Since this item is systematically subjectively assessed by the patient, the investigators would like to know if these subjective data are correlated with objective data. Aims of this study are: 1) To describe what means limitation of activity for asthma patients and how they deal with; 2) To describe the objective exercise capacity and characteristics of daily activity in two situations (on exacerbation, out of an exacerbation).

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Energy expenditure (expressed in MET's) measured during an ergospirometry, at the time of an exacerbation of asthma and 6 weeks later. | At the time of inclusion | One MET (Metabolic Equivalent of Task) is equal to an oxygen uptake about 3.5 ml O2/kg/min. |
Secondary
| Measure | Time frame |
|---|---|
| Walking distance in 6 min (expressed in meters) measured at the time of an exacerbation of asthma and 6 weeks later. | 6 weeks |
| Quality of life (assessed with the Asthma Quality of Life Questionnaire) measured at the time of an exacerbation of asthma and 6 weeks later. | At the time of inclusion |
| Self-assessment of activity limitation | 7 last days before inclusion |
