Influence of body position on diaphragmatic thickening fraction in healthy adults: advancing the standardization of diaphragm ultrasonography

Key Points

• Diaphragmatic thickening fraction is highest at a 70° body position, affecting diagnostic outcomes.
• The study indicates that consistent body positioning during ultrasonography is crucial for accurate assessments.
• Research demonstrates significant variability in diaphragm measurements based on body position during imaging.
• These findings highlight the importance of standardizing assessment conditions for enhanced clinical diagnostics.
