dc.description.abstract | Background: The diaphragm is considered the main muscle involved in breathing and also linked to
trunk stabilization functions. Up to date, rehabilitative ultrasound imaging (RUSI) has been the most
used technique to evaluate unilaterally the transcostal diaphragm thickness. Nevertheless, the inspiratory
activity of both hemi-diaphragms is bilaterally performed at the same time, and its simultaneous evaluation
with a thoracic orthosis could improve its assessment as well as its re-education with visual biofeedback of
both hemi-diaphragms at the same time. The purpose was to evaluate the reliability and repeatability of
simultaneous thickness measurements of both hemi-diaphragms bilaterally during normal breathing using a
thoracic orthosis that allowed bilateral fixation of both right and left ultrasound probes.
Methods: The study was conducted in 46 healthy subjects, whose diaphragm thickness was measured
bilaterally and simultaneously in the anterior axillary line during relaxed breathing with a designed thoracic
orthosis and 2 ultrasound tools. Intra-examiner (same examiner), inter-examiner (2 examiners), intrasession
(1 hour) and inter-session (1 week) reliability and repeatability between each pair of measurements of
diaphragm muscle thickness were analyzed during normal breathing.
Results: Reliability and repeatability for intra-session evaluations using the thoracic orthosis were
excellent to evaluate simultaneous thickness of both hemi-diaphragms by bilateral probes fixation (intraclass
correlation coefficient =0.919–0.997; standard error of measurement =0.002–0.007 cm; minimum detectable
change =0.006–0.020 cm), without systematic errors (P>0.05) between each pair of measurements.
Nevertheless, inter-session evaluations varied from good to excellent using the bilateral probes fixation
(intraclass correlation coefficient =0.614–0.984; standard error of measurement =0.006–0.028 cm; minimum
detectable change =0.017–0.079 cm), although some systematic errors were presented (P<0.05). Conclusions: Good to excellent reliability and repeatability was shown for simultaneous thickness
measurements of both hemi-diaphragms bilaterally during normal breathing. Despite systematic errors were
presented for some inter-examiner assessments, the use of the thoracic orthosis that allowed bilateral fixation
of ultrasound probes could be recommended for simultaneous hemi-diaphragms breathing re-education by
visual biofeedback. | spa |
