Diaphragmatic Function in Stroke Patients.

Cough Clinical Trial

Official title: Diaphragm Function Evaluation in Stroke Patients During Voluntary Cough Using Sonography

Status Completed

Clinical Trial Summary

• This study attempts to elucidate whether stroke patients with dysphagia have reduced diaphragm movement during voluntary coughing, and also during deep inspiration and expiration than stroke patients without dysphagia.

• This study will also compare various spirometric measurements with the diaphragmatic motions.

Clinical Trial Description

Stroke is a debilitating condition that can impair multiple functions, including swallowing. Stroke patients with dysphagia, are known to have reduced cough due to multiple mechanisms and this can impair their expectorate function. This can lead to accumulation of sputum and mucoid, ultimately resulting in aspiration pneumonia. Stroke patients, especially those with dysphagia, are also known to have expiratory muscle weakness and weak cough than healthy controls. Stroke patients are also known to have reduced diaphragm movement than healthy subjects. Sonography is a useful tool that can easily and reliability measure diaphragm movement. Whether stroke patients with dysphagia have reduced diaphragm movement than those without dysphagia and whether this affects voluntary cough have not been reported yet.

This study attempts to evaluate diaphragm movements during voluntary cough in stroke patients with dysphagia and determine whether this reduced diaphragm movement correlates to their peak flow meters during voluntary cough. ;
