Identificação de equipamentos e procedimentos utilizados por fisioterapeutas brasileiros para testes de endurance muscular inspiratória

Abstract

The assessment of inspiratory muscles through the inspiratory muscle endurance test (IME), defined as the ability to support this task over time, currently presents wide range of instruments and procedures for its measurement. This study aimed to identify the different equipment, procedures and assessments of IME tests among Brazilian physical therapists. It is a cross-sectional study carried out through a questionnaire sent individually by electronic mail to each participant. One hundred and thirteen physical therapists from different regions of the country, many practicing in the clinic and in the teaching field (52.1%), said they measured IME a few times (48.7%). The aneroid manovacuometer was used by 42.5% of the professionals. The nose clip and the hard plastic or paper tubular incentive spirometer were the most used accessories during the test, corresponding to 51.8% and 33%, respectively. The maximum voluntary ventilation test was used to assess the inspiratory endurance, reported by 23% of the respondents. The constant load test for endurance assessment was adopted by 51.2% of the physical therapists, and 54.9% associated verbal commands with the demonstration for the test application. The interpretation of the measured values was made with reference values by 25.7% of respondents. We identified that Brazilian physical therapists interviewed did not show the same conduct for IME tests. However, the equipment, procedures and assessment form are used based on the guidelines on the subject and according to the availability of resources of the service.
