Abstract

Abstract: Objective: To investigate the impacts of abdominal obesity and body position on kinematics of the chest wall. Methods: A cross-sectional design was conducted. Twenty abdominal obesity and twenty control males were performed four body positions for 5 min each: (1) sitting without back support, (2) sitting with back support, (3) Fowler's position, and (4) supine. Kinematics of chest wall including thoracoabdominal asynchrony, diameter changes, and ventilatory function were evaluated using optoelectronic plethysmography. Results: Thoracoabdominal asynchrony in obesity group has higher than control group among body position (p < 0.01). Obesity group significantly decreased diameter changes across body positions compared to control group (p < 0.01). Sitting without and with back support showed the lowest for thoracoabdominal asynchrony but the greatest chest wall diameter changes and ventilatory function than Fowler's and supine positions (p < 0.01). Conclusions: The current finding supports the significant effect of abdominal obesity and different body positions on kinematics of chest wall. Both sitting without and with support positions are recommended for synchronizing thoracoabdominal motion, maximizing chest wall diameter changes, and ventilatory function – this would therefore likely reduce the risk of respiratory disease and complications compared with lying positions. Highlights: Abdominal obesity and body position influenced kinematics of the chest wall. Abdominal obesity induced the degree of thoracoabdominal asynchrony. Sitting provides the benefit for restoring the chest wall kinematics. Supine induced the highest incoordination movement between ribcage and abdomen. The findings have useful for improving chest wall motion to tailor treatments.
