Abstract

PURPOSE:  To evaluate the applicability and acceptability of three different protocols of inspiratory muscles incremental test in normal children.

METHODS:  The children recruited were aleatory submitted to three inspiratory muscles incremental tests (IMT). JOHNSON et al (IMTI), JONG et al (IMTII) e NICKERSON E KEENS (IMTIII). Each protocol was performed with 24 hours between them. The inspiratory muscles endurance was performed 30 minutes after the IMT conforming, and was defined, as the time the subject was able to sustain breathing against an inspiratory pressure load equivalent to 80% of the maximal tolerated load in the IMT.

RESULTS:  A total of 24 children completed the study, 13 boys and 11 girls. The mean age was 10,4±2,1 years. The mean values for lung volumes were withing normal limits. There were no statistically significant between initial and final heart rate, breathing frequency, oxygen saturation and dyspnea score; the time of the test; inspiratory muscles endurance comparing the three tests studied. However, the children were unable to sustain the maximal load in the (IMTIII) so they did not do the inspiratory muscles endurance. About the Borg score and the sustained load the results showed IMTI = IMT II< IMTIII (p< 0,001) and IMT II = IMTIII > IMTI (p< 0,001) respectively. IMTIII was the only protocol witch the children did not achieve the maximal load during the test.

CONCLUSION:  The results suggest that the IMT II protocol demonstrated better applicability and acceptability in normal children as compared with IMTI and IMTIII.

CLINICAL IMPLICATIONS:  The best inspiratory muscles test to evaluate the inspiratory muscles endurance in normal children was IMTII because it does not underestimate the maximal load sustained.
