Title: | Gender and speech related differences on thoracoabdominal motion during cognitive tasks | Authors: | Van Hove, Olivier Debeir, Olivier Andrianopoulos, Vasileios Leduc, Dimitri Deboeck, Gael BONNECHERE, Bruno |
Issue Date: | 2021 | Source: | EUROPEAN RESPIRATORY JOURNAL, 58 (suppl 65) (Art N° PA3228) | Abstract: | Background: Assessment and evaluation of thoracoabdominal motion during breathing is clinical relevance. This study aims to highlight parameters that can influence thoracoabdominal management strategies. Methods: Thirty healthy young subjects (25 ± 4 years old, 57% women) were recruited. Thoracoabdominal contribution of respiration was evaluated based on the images derived from the Kinect V2® camera. Thoracoabdominal analysis (TAA) by regression was performed between thoracic and abdominal motions, and the angle between the regression line and the x-axis was computed. Based on these angles three different patterns were defined: a) homogeneous breathing – when angle range (AR)= 45°, b) abdominal breathing when AR <45°, c) thoracic breathing when AR >45°. Breathings were recorded for 1min during the three different conditions: at rest and at two cognitive tasks (count back 3): one performed pure mentally, whilst other expressed by speech also. Results: The respiratory rate was decreased by 18% (p = .004) in oral task and increased by 20% (p = .005) in mental task. In regards to the TAA, there is no interaction for the three conditions: rest, oral and mental task (p = .52). A significant interaction effect for sex was observed: women presented higher values than men (54±9°vs 45±13°, p < .001). The interaction between the conditions and sex is not significant (p = .51). Measurements and Main Results: Women seem to have more thoracic breaths than men. This may have an effect during clinical evaluation or even have implications in postural control. Speech does not seem to have a significant effect on TAA but well on the respiratory rate. | Keywords: | Adults;Physiological diagnostic services;Experimental approaches | Document URI: | http://hdl.handle.net/1942/36700 | ISSN: | 0903-1936 | e-ISSN: | 1399-3003 | DOI: | 10.1183/13993003.congress-2021.PA3228 | ISI #: | 000747452104018 | Category: | M | Type: | Journal Contribution |
