Effect of Body Tilting on Diaphragm Excursion and Thickness in the Stroke Patients With Tracheotomy by Ultrasonography

Study Overview
=================
Brief Summary
-----------------
The purpose of this study was to examine whether if the effect of standing with assistance of the tilt table on diaphragm excursion and thickness in the stroke patients with tracheotomy.

Detailed Description
-----------------
40-45 stroke patients with tracheotomy were passive tilting (α=0°, 30°, 60°) by an electric tilt table in the random order. The diaphragm excursion and thickness were measured by ultrasonography on three tilting during the quiet breathing. Besides, the intraclass correlation coefficient (ICC) were calculated to assess the reliability of the diaphragm ultrasonography in this population.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Diaphragm excursion | The measurement of the diaphragm dome excursion following the M-mode approach during quiet breathing could provide indirect information about inspiratory volume. | Half an hour | 
| Diaphragm thickness | The diaphragm thickness was measured by B-mode approach providing clear visualization of the diaphragm morphology at the zone of apposition at the quiet breathing on the three tilting. | Half an hour | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| The intraclass correlation coefficient (ICC) | For the ultrasonography assessment, the intraclass correlation coefficient (ICC) was analyzed by using the two-way mixed-effects ICC [2.1] model with 95% confidence intervals (CIs). | Within-24h |
