Syrebo SY-UEA2 Upper Limb Rehabilitation Robot — Gamified Arm & Shoulder Recover

The Syrebo SY-UEA2 Upper Limb Rehabilitation Robot is a clinical-grade, AI-assisted robotic therapy system designed for comprehensive arm and shoulder rehabilitation. Combining high-precision optical positioning, flexible robotics, and gamified training, the SY-UEA2 transforms conventional upper limb therapy into an engaging, data-driven rehabilitation experience — from acute post-stroke passive recovery through to functional independence.

4-Mode Motor Training — Full Coverage of the Rehabilitation Cycle — The SY-UEA2's motor training framework is structured around the Medical Manual Test (MMT) grading system, ensuring appropriate therapy at every stage of recovery:

• Passive Training (MMT Gr. 0) — For patients in the acute or early recovery phase with no voluntary movement. The robot fully guides the arm through the prescribed trajectory, maintaining range of motion, preventing contractures, and initiating neural pathway stimulation without requiring patient effort.
• Assistive Training (MMT Gr. 1–2) — For patients with minimal voluntary movement. The robot provides partial mechanical assistance while the patient contributes available effort, gradually increasing active participation and building early strength.
• Active Training (MMT Gr. 3) — For patients with fair strength who can initiate movement. The robot follows the patient's intended trajectory, offering support and guidance while maximising active engagement to reinforce motor recovery.
• Resistance Training (MMT Gr. 4–5) — For patients in the late recovery stage. Controlled resistance is applied against the patient's movement to build muscle strength, challenge motor capability, and prepare for functional independence.

Cognitive Training — Neuroplasticity Through Engaging Games — The SY-UEA2 integrates structured cognitive training alongside motor therapy, leveraging neuroplasticity principles through four interactive game-based programmes:

• Categorisation Game — Colour and shape recognition exercises targeting perception and visual discrimination.
• "Let Goods Back" Game — Spatial memory and focused attention training for working memory enhancement.
• "Catch Bees" Game — Divided and sustained attention exercises incorporating visual tracking practice.
• "Something New" Game — Unilateral neglect training with working memory challenges and spatial awareness development.

High-Precision Optical Positioning Technology — The SY-UEA2 uses advanced infrared optical sensors achieving millimeter (mm) level positioning accuracy with microsecond response time. This delivers:

• Real-time coordinate mapping of every arm movement
• Continuous speed, strength, range of motion, and endurance monitoring
• Simultaneous display of target trajectory (blue) vs. patient's actual trajectory (orange) for immediate visual feedback
• Automatic report generation for evidence-based treatment decisions and patient progress documentation

Customisable Training Trajectories — Beyond its pre-set joint-specific movement patterns, the SY-UEA2 supports unlimited custom trajectory programming:

Pre-set trajectories include full ROM arc movements, elbow flexion/extension, shoulder internal/external rotation, scapular protraction/retraction, unilateral neglect training, and balance/coordination exercises. Therapists can create, save, and progressively adjust personalised programmes for each patient.

Portable, Ergonomic & Multi-Setting Design

Despite its advanced capabilities, the SY-UEA2 weighs only 8 kg and features an omnidirectional mobile chassis for 360-degree movement — making it easy to reposition between treatment areas or wards.

• Adjustable arm length accommodates a wide patient range
• One-touch height adjustment compatible with wheelchairs
• Adaptable for bedside, seated, and standing use positions
• Suitable for inpatient wards, outpatient clinics, and home settings

4-Layer Safety Protection System

Patient safety is enforced through four independent protection mechanisms:

• Force Limitation Protection (E10) — Prevents excessive force and alerts if overloaded
• Overload Protection (E2) — Monitors system capacity and triggers device restart alerts
• Emergency Stop Function (E8) — Instant training halt during safety-sensitive periods
• Electronic Fence — Boundary protection preventing movement outside prescribed safe zones
