Upper Extremity Feedback Training and Evaluation System (AE-AI2)

The AE-AI2 is an ergonomically engineered robotic upper limb rehabilitation and evaluation system, part of Kiyash Healthcare's AI Rehabilitation Robot series. The adjustable upper limb weight reduction manipulator based on ergonomics provides patients with training and evaluation in three-dimensional space — combining a 6 degrees-of-freedom (6-DOF) robotic manipulator, built-in scenario biofeedback games, and standardized evaluation tools to accurately analyze and evaluate patients' abilities, accelerating the process of upper limb rehabilitation and neurological recovery.

Key Features —

1. 6-DOF Robotic Manipulator — Full Three-Dimensional Movement : The 6-DOF manipulator can adjust one-dimensional motion of single joint and two-dimensional and three-dimensional motion of multiple joints as required. This six-degrees-of-freedom architecture allows the device to guide isolated single-joint movement (for example, elbow flexion/extension alone) as well as complex, multi-joint, three-dimensional reaching and functional movement patterns that more closely replicate real-world activities of daily living — a critical distinction from simpler single-axis rehabilitation devices that can only move the limb along one fixed plane.
2. Adjustable Weight Reduction (Gravity Support) : The adjustable upper limb weight reduction manipulator compensates for the weight of the patient's own arm during training — allowing patients with significant weakness, who could not otherwise lift or move their arm unassisted, to actively participate in guided movement. As strength returns, the level of weight support can be reduced, allowing the training protocol to progress in difficulty alongside the patient's recovering function.
3. Grip Strength Feedback : The weight reduction device and grip strength feedback system can compensate the strength and collect the grip strength according to the actual needs of the upper arm and the lower arm. Integrated grip strength measurement allows hand function — often significantly impaired in stroke and neurological conditions — to be objectively tracked alongside proximal arm movement, giving clinicians a more complete picture of upper limb recovery than arm movement training alone would provide.
4. Scenario Simulation Biofeedback : Built-in incentive feedback games and standardized evaluation tools transform guided robotic movement into interactive, game-based training. Real-time visual feedback on screen keeps patients engaged with their own performance during each repetition — a well-established strategy in neurorehabilitation for maintaining patient motivation and treatment adherence across the many sessions required for meaningful functional recovery.
5. One-Key Left/Right Arm Switching : Exclusive upgrade of left and right arm replacement technology, one key switching of left and right arms, intelligent recognition and training of arm side, and improvement of therapist's work efficiency. Rather than requiring manual reconfiguration or a separate device setup for the affected side, the ZEPU-AI2 allows the therapist to switch between left-arm and right-arm training configurations with a single control action — reducing session setup time and supporting efficient patient throughput in busy rehabilitation departments.
6. Wireless Data Transmission : Wireless transmission technology is adopted, which is beautiful and convenient — eliminating cable clutter around the patient and workstation, simplifying the clinical environment, and supporting a cleaner, more modern treatment room setup.
7. Patient Management & Course Tracking : Integrated patient information and course management software supports patient management, prescription formulation, functional training and evaluation tools — enabling clinicians to document treatment plans, track progress across multiple sessions, and build an objective evidence base of functional improvement over the course of a rehabilitation programme.
