Traditional Upper Limb RehabilitationRobot

——Effective, but still has limitations

Upper limb dysfunction is a major rehabilitation challenge following common conditions such as stroke, trauma, and nerve injuries. Traditional upper limb rehabilitation robots guide patients' limbs through repetitive training using robotic arms or linkage structures, enabling high-volume and high-frequency rehabilitation movements, which play a positive role in improving joint mobility and preventing muscle atrophy.

However, they also have some shortcomings:

☹Dependent on external drives:Most training focuses on "passive movement," with limited active participation from the patient's brain.

☹Insufficient Neuroplasticity:The lack of a direct brain-muscle functional reconstruction mechanism often limits rehabilitation outcomes to "mechanical movements."

☹Lack of immersive experience:The training mode is单一, lacking趣味性, and患者依从性is not高.

This means that traditional equipment tends to "move you along" rather than "help you truly learn how to move."

Sunnyou Brain-Computer Interface - Upper Limb Rehabilitation Robot

——Redefining the New Model of Rehabilitation

In response to the limitations of traditional rehabilitation, Sunnyou Medical has newly launched a multimodal upper limb rehabilitation robot that integrates Brain-Computer Interface (EEG) and Functional Electrical Stimulation (FES), paving a new way for upper limb functional reconstruction.

✔Brain-Computer Interface (EEG)

Real-time capture of patients' motor imagery signals in the brain, converting "intentions" into motion commands, and establishing the neural pathway from brain to device to muscle.

✔Functional Electrical Stimulation (FES)

When patients generate movement intentions, precisely activate target muscle groups to achieve neuro-muscular synergistic training, accelerating neural remodeling and motor function recovery.

Sunnyou's Brain-Computer Interface - Upper Limb Rehabilitation Robot is redefining rehabilitation robots, moving beyond mechanical traction to reconnect the brain and body.

9. Upper Limb Rehabilitation Robot: Brain-Computer Interface + Functional Electrical Stimulation

BCI provides brain intention, FES assists in muscle activation, and robots provide mechanical movement. Brain generates intention → EEG decoding → control of robot/FES → motion feedback to the brain, forming a closed-loop neurorehabilitation system.

Brain-Computer Interface Combined with Functional Electrical Stimulation System (BCI-FES) creates a closed-loop circuit between motor planning and sensory perception, assisting stroke patients in controlling impaired limbs through voluntary intention to generate corresponding movements.

Sunnyou's Brain-Computer Interface Neuroregulation Rehabilitation Treatment Center focuses on Brain-Computer Interface (BCI) technology, establishing five major systems: EEG acquisition, proprietary algorithms, brain-controlled rehabilitation products, real-life application scenarios, and scientific research. Relying on Sunnyou's Brain Science Lab, the center develops high-precision EEG acquisition systems and intelligent algorithms, using non-invasive electrodes to capture patients' intentions. Through the synergy of "brain-machine-body," it rebuilds the motor and cognitive closed-loop, allowing paralyzed individuals to regain control of their lives with their "thoughts."
