Advanced Robotic Upper Limb Exoskeleton

Elevate upper limb rehabilitation to the highest level of precision with the Advanced Robotic Upper Limb Exoskeleton. This innovation goes beyond merely moving a patient’s arm; it is a technology that synchronizes bilateral brain activity (Bilateral Control) with a virtual environment. It enables patients with hemiparesis or muscle weakness to reclaim their activities of daily living (ADLs) faster and more naturally, adhering to the world-class rehabilitation standards at PYONG Rehabilitation.

What is the 3D Bilateral Robotic Exoskeleton?

It is a wearable rehabilitation robot designed for the arms and hands, supporting 3D movement across the shoulders, elbows, and wrists. Its standout feature is the "Bilateral Simultaneous Control" system—widely recognized as a premier rehabilitation method for stroke patients. By using the healthy arm to lead the movement, it stimulates the damaged side of the brain to command the weakened arm to move in perfect synchronicity.

Mechanism of Action

• Bilateral Integration: Utilizes "Mirror Therapy" principles, where the strong arm sends signals through the robotic system to support and guide the weakened arm in identical ranges of motion.
• Active-Assistive Mode: Intelligent sensors detect the patient’s intended effort. If the force is insufficient, the robot supplements the necessary Torque to complete the movement.
• Task-Oriented Training: Patients practice through simulated daily life scenarios (ADLs) on an interactive 3D screen to forge new neural pathways (Neuroplasticity), helping the brain relearn how to reach, grasp, and move.

Technical Specifications

• 3D Motion Support: Supports 7 degrees of freedom, mimicking the natural complexity of human arm movement.
• Mirror Image Mode: Synchronized bilateral command system to stimulate the affected brain hemisphere.
• Anti-Gravity Support: Gravity compensation system that allows patients with zero muscle strength to move their arms effortlessly.
• Immersive Games: 3D training programs with adjustable difficulty levels tailored to patient progress.
• Data Analytics: Records detailed Range of Motion (ROM) and strength data during every session.

Medical Evidence-Based Integration

• Chronic Stroke Rehabilitation: Research confirms that Bilateral Training (simultaneous two-arm practice) improves arm function scores (Fugl-Meyer Assessment) more effectively than unilateral training by increasing inter-hemispheric connectivity.
• Proprioception Stimulation: Patients with impaired joint-position sense show significant improvement through real-time audio-visual Biofeedback provided by the system.

Who Is It For?

1. Stroke Patients: Both acute and chronic phases seeking to regain arm and hand functionality.
2. Traumatic Brain Injury (TBI): To improve hand-eye coordination.
3. Spinal Cord Injury (SCI): Cervical-level injuries affecting arm strength.
4. Post-Nerve or Tendon Surgery: For those requiring precise movement training in a safe, controlled environment.

Frequently Asked Questions (FAQs)

Q1: Can I train if I have no arm strength at all (Grade 0)?

A: Absolutely. The robot features a Passive Mode and Anti-Gravity support to guide your arm through movements, preventing joint stiffness and stimulating brain-to-muscle signals.

Q2: How does this differ from traditional manual physical therapy?

A: Robotics provide objective, measurable data and allow for much higher repetition (High Repetition) with consistent quality. The gamified experience also boosts motivation, encouraging longer and more effective sessions.

Q3: How many sessions are needed to see results?

A: We generally recommend at least 10–15 continuous sessions to see noticeable changes in muscle strength and improved limb control.
