Wearable electronics for swallow-graphy in stroke patients

Recruiting

Conditions: Healthy volunteers agreeing to be a part of the study without any swallowing dysfunction.
Dysphagia,

Brief Summary: Swallowing dysfunction in stroke patients is a major burden and 30% more mortality is observed in such cases. Swallowing assessment should be done repeatedly to assure that the patients is doing well before oral feeding is initiated. There are existing methods to assess swallowing in stroke patients such as; bedside clinical assessment, video-fluoroscopy, barium swallow. Video-fluoroscopy/Barium swallow is gold standard for evaluation of swallowing dysfunction. These existing methods are provocative and may lead to aspiration, also it is not feasible to conduct these tests repeatedly. Expert specialists or trained healthcare workers are required to perform these tests on patients. Hence, there is pressing need of a non-invasive device which can detect swallowing dysfunction, also a device which can be used repeatedly to determine the status of swallowing dysfunction. This device can also be used by non-healthcare worker or patientâ€™s attendants; it will not require any special training. To our knowledge there is no such device which is being used globally. For these reasons we propose to conduct this study to determine the efficacy of the non-invasive developed tool in testing swallowing difficulty in stroke patients.
