[Evaluation of free walking as a provocation method for detection of nonspecific bronchial hyperreactivity in children].
The bronchial hyperreactivity alone does not stand for illness but it is typical of asthma. Nonspecific tests are on a low level of standardization and the results of various research groups are difficult to compare. We used the free running provocation test compared with the inhalation test of acetylcholine in a routine lung function laboratory. Using the flow-volume curve both methods were of a comparable value although not absolute equal. Running-provocation seems to be especially qualified for the ascertainment of exercise-induced bronchospasm. A preexisting obstruction more often led to a positive result with increased reaction. The MEF values on low level of FVC proved to be especially sensitive. Free-running using the flow-volume curve for evaluation of ventilation is a cheap, noninvasive, natural, and in our opinion qualified method for the estimation of nonspecific bronchial hyperreactivity.
