The A2 Upper Limb Intelligent Feedback Training System applies computer virtual technology combined with rehabilitation medicine principles to simulate human upper limb movements in real time. Patients can perform multi-joint or single-joint rehabilitation training within a computer-controlled virtual environment while receiving continuous feedback on their performance. Product Overview Targeting patients with upper extremity dysfunction caused by stroke, severe brain injury, or other neurological conditions, the A2 provides structured arm rehabilitation through a combination of weight support, intelligent feedback, and 3D spatial training capabilities. The system includes a built-in assessment module that enables therapists to track progress and adjust treatment protocols based on objective data. Clinical research supports the premise that definite, task-oriented training effectively improves upper extremity function in neurological patients—a principle that guides the A2’s design philosophy. The A2 Upper Limb Intelligent Feedback Training System is a rehabilitation robot by Yeecon, featuring CE certification and adjustable weight support across shoulder, elbow, and wrist joints. Upper Limb Weight Support Training : Adjustable support system reduces effective arm weight, enabling patients with minimal strength to perform reaching and manipulation tasks Intelligent Feedback System : Real-time visual and auditory feedback during training activities 3D Spatial Training : Multi-dimensional movement exercises beyond simple planar motion Multi-joint and Single-joint Modes : Flexibility to isolate shoulder, elbow, or wrist movements or coordinate all joints together Assessment System : Evaluation of wrist joint range of motion, forearm muscle strength, and grip strength with results stored in patient databases Technical Specifications The A2 Upper Limb Intelligent Feedback Training System is a rehabilitation robot by Yeecon, featuring CE certification and 1D, 2D, and 3D training dimensions with individual patient databases for progress tracking. Weight Support System The adjustable weight support feature addresses a key challenge in early-stage upper limb rehabilitation: patients with weak muscle strength cannot lift their arms against gravity to perform functional reaching movements. By reducing the effective weight of the arm, the A2 enables these patients to: Move more easily and practice functional patterns earlier in recovery Improve residual neuromuscular control through active participation Progress through decreasing support levels as strength improves Assessment Capabilities The A2’s assessment module evaluates: Wrist joint range of motion : Measuring flexibility and movement limitations Forearm muscle strength : Quantifying force generation capacity Grip strength : Assessing hand function Results are stored in individual patient databases, allowing therapists to analyze treatment progress over time and modify rehabilitation prescriptions accordingly. The system generates assessment reports displayable as line graphs, bar graphs, or area graphs, with printing functionality for clinical documentation. Clinical Applications The A2 addresses upper limb rehabilitation needs for patients with: Stroke-related hemiparesis affecting arm function Traumatic brain injury with upper extremity involvement Cerebrovascular malformation sequelae

Other neurological conditions causing arm dysfunction Post-surgical recovery requiring upper limb rehabilitation Training Approach Based on motor learning principles, the A2 provides: High training efficiency through guided, repetitive practice Real-time visualization of performance feedback Accurate progress tracking through objective assessment data Enhanced patient motivation through interactive virtual scenarios Increased attention and initiative during training sessions Regulatory Status Frequently Asked Questions What conditions can the A2 system treat? The A2 is designed for patients with upper limb dysfunction resulting from stroke, cerebrovascular malformation, severe brain trauma, or other neurological diseases. It is also appropriate for patients recovering from surgery who need to restore upper limb function. How does weight support help rehabilitation? Many neurological patients lack sufficient strength to lift their arms against gravity in the early recovery phase. The A2’s adjustable weight support system compensates for this weakness, allowing patients to practice functional arm movements before they can independently overcome gravity. As patients improve, support levels decrease to progressively challenge their recovering muscles. What data does the A2 system provide? The system generates quantitative data on wrist range of motion, forearm strength, and grip strength. All measurements are stored in patient databases, enabling trend analysis across multiple sessions. Reports can be displayed in various graph formats and printed for medical records.
