Abstract

The present disclosure is directed to apparatuses and methods for diagnosing a swallowing dysfunction. The apparatuses may include a multi-parametric dysphagia analysis system in a plastic foil. The analysis systems may be smart sensing systems that are flexible, lightweight, and based on substrates having low-cost printed electronics technologies thereon. The methods may include measurement and classification of non-invasive parameters that may be indicative of a swallowing dysfunction or the probability of same. In a general embodiment, the methods include placing a sensor on a patient for measurement of at least one parameter associated with the patient's swallowing profile. The measured parameter is then analyzed and compared with several known normal and dysphagic swallowing profiles to provide an indication of the probability of an underlying swallowing dysfunction.

First claim

The invention is claimed as follows:

1. A method of treating a patient with a swallowing dysfunction, the method comprising:
measuring a swallowing profile of the patient using a sensor, the sensor comprising a flexible substrate, and at least one printed electronic selected from the group consisting of a microcontroller, at least one sensor, an antenna, and combinations thereof, wherein the flexible substrate and at least one printed electronic are encased in a plastic foil;
sending a sensor output to a device having a processor and a swallowing profile database, wherein the swallowing profile database comprises data relating to both healthy patients and patients having swallowing dysfunctions, wherein the data relating to healthy patients is recorded using two methods: i) recording truly healthy data during an initial measurement using a videofloroscope; and ii) recording composite healthy data during a second measurement, the composite healthy data reflecting a first function of a neck of the patient, the neck having an apparent dysfunction of the patient and a second function of a lip seal of the patient that is functioning as per a normal individual;
comparing the sensor output with the data of the swallowing profile database relating to both healthy patients and patients having swallowing dysfunctions, linking the sensor output to an underlying swallowing dysfunction without linking the sensor output to an underlying disease, to obtain a first signal output indicative of a range of a swallowing dysfunction;
comparing the first signal output to a recommended therapy database to obtain a second signal output representative of a therapy recommendation comprising at least two of: physical therapy, dietary modification, oral health improvement, electrical stimulation, biofeedback, and pharmacological treatment; and
treating the patient in accordance with the second signal output by administering an effective amount of the therapy recommendation to the patient.

2. The method according to claim 1 , wherein the first signal output is an electronic signal.

3. The method according to claim 1 , wherein the data is obtained from measurements made with videofluoroscopy tests for at least 500 patients comprising healthy patients and dysphagic patients.

4. The method according to claim 1 , wherein the underlying swallowing dysfunction is a biomechanical fault.

5. The method of claim 1 , wherein the database is a remote database located remote from the sensor.
