Dysphagia seems to be quite common and potentially severe in schizophrenia, which may lead to acute asphyxia or pneumonia. Dysphagia in schizophrenia could be associated with drug-induced Parkinsonism, dystonia, tardive dyskinesia, dry mouth, excessive saliva, and other complications. Inadequate oral hygiene may lead to the accumulation of plaque, which can cause oral diseases and consequently result in tooth loss. This could be one of the significant factors affecting impaired masticating and swallowing abilities. An experimental study with random assignment will be adopted. The participants from 2 hospitals will be assigned to two groups: experimental group (n=50), and control group (n=50). The experimental group will receive 'AI-assisted Masticatory Muscle Training' sessions, each lasting 20 minutes, before each of their three daily meals. The plaque index, Winkle tongue-coating index, dry mouth, repetitive saliva swallowing, saliva flow rate, biting force, tongue pressure, oral frailty, RSST, DDK, and oral care behaviors were assessed at baseline, as well as during the 3-month follow-ups.

The plaque index, Winkle tongue-coating index, dry mouth, repetitive saliva swallowing, saliva flow rate, biting force, tongue pressure, oral frailty, RSST, DDK, and oral care behaviors were assessed at baseline, as well as during the 3-month follow-ups. Generalized Estimating Equations (GEE) were used to analyses the indicated effects.

SINGLE
Enrollment

An artificial intelligence (AI) recognition system for the 'AI-assisted Masticatory Muscle Training,' tailored to train masticatory muscles in patients with schizophrenia. By finishing certain exercise per day, expecting the experimental oral hygience, masticating and swallowing fuction could be advanced,
Anterior tongue strength
Using the IPOI machine to test participants' tongue strength once a month for a total of 3 months, and a follow-up review 3 months after the end of treatment
Time frame: From day 1 of enrollment to the end of the treatment period (up to 3 months)
Posterior tongue strength
Using the IPOI machine to test participants' tongue strength once a month for a total of 3 months, and a follow-up review 3 months after the end of treatment
Time frame: From day 1 of enrollment to the end of the treatment period (up to 3 months)
Masticatory Performace
Using colour-changing chewing gum to assess the ability, the colour would be changed according to the frequency of chewing
Time frame: From day 1 of enrollment to the end of the treatment period (up to 3 months)
Oral Hygiene
Using the Plaque index, Winkle tongue-coating index to assess participants' oral hygiene
Time frame: From day 1 of enrollment to the end of the treatment period (up to 3 months)
Swallowing Performance
Using the Repetitive Saliva Swallowing Test to assess the ability to swallow. The times of participants swallowed within 30 seconds would be recorded
Time frame: From day 1 of enrollment to the end of the treatment period (up to 3 months)
Oral Care Behaviours
Using a survey to collect participants' behaviours
Time frame: From day 1 of enrollment to the end of the treatment period (up to 3 months)
Cognitive Function
Using MoCA to assess cognitive ability once at the beginning of the experiment
Time frame: From day 1 of enrollment to the end of the treatment period (up to 3 months)
