Hemiplegia Rehabilitation Device

Hemiplegia Rehabilitation Device Combining Contralateral Motion Synchronization and Visual Illusion

This technology is a hemiplegia rehabilitation device that measures the movement of a patient's unaffected limb using sensors such as motion capture, electromyography (EMG), and inertial measurement units (IMU). By analyzing this data in real time, it drives the joints of an exoskeleton robot worn on the hemiplegic side, enabling synchronized bilateral limb movement.

Conventional hemiplegia treatment often relies on simple, repetitive motions, resulting in low rehabilitation efficiency. Existing wearable robots function primarily as simple assistive devices, which limits their ability to induce neuroplasticity and makes it difficult to implement systematic rehabilitation that leverages a patient's cognitive illusions.

This technology proposes a system that integrates a control unit—which receives motion data from the unaffected limb to drive the hemiplegic-side robot in real time—with a visual separation device, such as a screen or mirror, that blocks the view of the unaffected limb to make the patient perceive that their hemiplegic side is moving normally. This approach provides effective rehabilitation by inducing neuroplasticity. It can be used for the rehabilitation of stroke patients with hemiplegia, offering superior therapeutic outcomes compared to traditional repetitive training by combining visual illusion with robotic assistance to stimulate neuroplasticity.

Key Features:

• An exoskeleton robot worn on the patient's hemiplegic side that drives joints in correspondence with the movement of the unaffected limb.
• A motion measurement unit that uses motion capture and sensors to measure the movement of the patient's unaffected limb in real time and transmits the data to the control unit.
• A control unit that receives the measured motion data of the unaffected limb and controls the robot to ensure the hemiplegic side moves accordingly.
• A screen or barrier that obscures the view of the unaffected limb while allowing the patient to see the movement of the hemiplegic side.
