Dysphagia, as a disease complication that seriously affects the basic quality of human life, is becoming a major public health challenge with the intensification of global aging.
Epidemiological studies show that approximately 590 million people worldwide suffer from swallowing disorders, among which the elderly are the most severely affected group.
Data from the National Bureau of Statistics shows that the incidence of dysphagia among people aged 65 and over in China is as high as 15%-30%, and among stroke patients, this rate is a staggering 51%-78%. With the accelerated aging of the population, dysphagia has become a problem that cannot be ignored.
The clinical manifestations of dysphagia are complex and varied and can occur at different stages of the swallowing process:
●Oral stage disorders: manifested as food retention, salivation, and difficulty chewing.
● Pharyngeal phase disorders: Inadequate laryngeal elevation, delayed swallowing reflex, and increased risk of aspiration.
●Esophageal disorders: food reflux and pain behind the sternum.
According to the above different stages of symptoms, rehabilitation methods can be roughly divided into the following categories:
Basic functional training
1. Indirect training (non-eating training): K-point stimulation, Shaker training
2. Direct training (feeding training): compensatory strategies, food modification
Physical factor therapy
● Electrical stimulation techniques: NMES (neuromuscular electrical stimulation), pharyngeal electrical stimulation (PES).
● Neuromodulation technologies: rTMS (repetitive transcranial magnetic stimulation), tDCS (transcranial direct current stimulation).
Brain-computer interface technology solves the problem of swallowing difficulties
With the advancement of technology, non-invasive brain-computer interfaces (BCIs) offer a new approach to addressing swallowing problems. By decoding the brain's swallowing intention in real time and simultaneously triggering peripheral neuromuscular electrical stimulation, they establish a closed-loop "perception-decision-execution" regulatory system. This innovative technological architecture transcends the limitations of traditional rehabilitation methods, achieving precise coordination between central control and peripheral intervention.
Core mechanism of brain-computer interface
The core mechanism of brain-computer interface in promoting swallowing function recovery lies in enhancing neural plasticity:
✔ Enhanced synaptic efficacy: Repeated electrical stimulation induces long-term potentiation (LTP) effect, strengthening synaptic transmission.
✔Neural network reorganization: promote compensation of the healthy hemisphere and reconstruction of the functional area of the affected side.
✔ White matter fiber remodeling: Increase the integrity and conduction efficiency of the corticobulbar tract.

Sunnyou Medical's independently developed brain-computer interface - swallowing nerve and muscle electrical stimulator uses brain-computer interface technology combined with swallowing electrical stimulation therapy to read the brain's neural signals that control swallowing, accurately trigger electrical stimulation of the throat muscles, and induce natural swallowing movements.
Features:
● Bidirectional symmetrical square waves eliminate the risk of electrolysis and can be used for long-term rehabilitation.
● Surface electromyography and a-factor assessment provide information for subsequent treatment.
● Passive electrical stimulation, triggered electrical stimulation, mirrored electrical stimulation, and brain-controlled electrical stimulation are available in multiple modes for targeted stimulation of dysfunctional muscles.
● Equipped with manual and automatic triggering, electrical stimulation therapy can be performed during active swallowing.
● Multimedia biofeedback enhances the fun and effectiveness of training.
