Pilot observational cohort study to determine whether waveform and flow traces from mechanical insufflation:exsufflation (MI:E) can be used to identify laryngeal responses to MI:E and thus optimise treatment algorithms in Neuromuscular patients

Investigating whether or not using a visual aid (waveform) on the MI:E device or "cough assist" will enhance how helpful the machine is in helping to increase the strength of your cough

This study is looking into whether or not using a visual aid (waveform) on the MI:E device or ‘cough assist’ will enhance how helpful the machine is in helping to increase the strength of your cough. Previous research studies used a camera in order to assess spasms within the airway, which can sometimes be caused with using the cough assist machine. The researchers aim is to look at whether the use of the waveform from the machine can identify airway spasm rather than using the camera to look at people’s airways.

This work will help to optimise individuals ability to clear secretions from their chest. This may reduce chest infections and improve symptom burden of secretions. The outcome of this study will help to inform of the best way to look after patients and provide some clinical guidance to physiotherapists on methods for assessing and treating airways responses to cough assist.
