With the increase in the proportion of the aging population in China, the treatment and rehabilitation of dysphagia has gradually become one of the problems that medical staff and patients' families often need to face in medical institutions and care centers. The reason for the difficulty in swallowing may be due to the functional deterioration caused by aging, which makes the patient unable to eat independently.

Medically, the common methods for diagnosing dysphagia are:

(1) Video-fluoroscopic swallowing study (VFSS), the subject must swallow barium (ie: contrast agent), and the process of swallowing food is actually recorded by the method of dynamic video. , Because VFSS is a radioactive test method, it will expose patients to radiation risks.

(2) Flexible fiber-optic examination of swallowing (FEES), this method uses endoscopy to check the swallowing status, mainly to allow the observer to visually observe the swallowing process of the subject; but FEES uses The invasive method can cause greater discomfort to the patient.

At present, domestic and foreign medical institutions have confirmed the use of EMG to detect swallowing movements, but in clinical applications, EMG signals caused by swallowing can be found, which may be similar to some head and neck movements (for example: nodding), or even It is when chewing, which is closely related to swallowing, that may cause misjudgment of swallowing behavior; in addition, the electromyography detection method requires electrodes to be attached to the throat, and the electrical conductivity between the electrodes and the skin is very important. When there is an operation on the neck or skin burns, the electrodes need to be attached to the skin, which may irritate the patient’s wound and cause discomfort. It will also affect the conductivity of the electrodes and the skin, reducing the accuracy of EMG signal detection.
