ystem Purpose and Technology
deXtreme is a robotic upper-limb rehabilitation system designed for patients recovering from stroke, traumatic
brain injury (TBI), and other neurological conditions.
The system uses BioXtreme’s proprietary Error Augmentation (EA) technology to accelerate motor learning and
functional recovery.
Training is performed through immersive 2D and 3D VR games, displayed on the system’s monitor, to increase
patient motivation and engagement.
The system incorporates real-time biofeedback, measuring muscle strength, range of motion, and additional
clinical parameters to accurately apply forces throughout each movement cycle.
Training Method:
The patient (seated) trains the right or left upper limb by repeatedly practicing guided motor tasks while
connected to the robotic arm. The robotic arm continuously measures performance and applies BX-exclusive
therapy forces according to real-time parameters such as:
· Movement speed
· Acceleration
· Force
· Vector
These measurements are analyzed and reflected within the training games.
Error Augmentation Forces:
During repetitive practice, the system applies environmental forces proportional to the patient’s motor error,
and in the direction of the error, to amplify it intentionally.
Neuroplasticity and Motor Memory:
These corrective actions serve as accurate motor experiences, helping the brain encode improved motor patterns
and develop stronger motor memory.
