NCT05098808

Brief Summary

In this prospective study we extracted acoustic parameters using PRAAT from patient's attempt to phonate during the clinical evaluation using a digital smart device. From these parameters we attempted (1) to define which of the PRAAT acoustic features best help to discriminate patients with dysphagia (2) to develop algorithms using sophisticated ML techniques that best classify those i) with dysphagia and those ii ) at high risk of respiratory complications due to poor cough force.

Conditions

Outcome Measures

Primary Outcomes (2)

  • Functional Oral Intake Scale

    Dysphagia severity as measured by the the Functional Oral Intake Scale obtained from standardized swallowing tests

    during the intervention

  • Cough strength

    Spirometry values : cough strength as measured by the spirometric values during voluntary cough

    during the intervention

Study Arms (2)

Dysphagia mild

Able to start oral feeding after assessment

Other: Acoustic features (from signals obtained during phonation)

Dysphagia severe

Non oral feeding and high risk of aspiration

Other: Acoustic features (from signals obtained during phonation)

Interventions

Acoustic features will be obtained via phonation files. A voice recorder application provided by Apple was used, and the sampling frequency of the sound was 44,100 Hz. The digitized cough sound signals were band-pass-filtered between 20 to 16,000 Hz to use data from the whole frequency band gathered by the iPad. In each case, the smart device was positioned 20cm from the patient

Dysphagia mildDysphagia severe
