Achieving Patient Recovery Through Adaptive Post Stroke Rehabilitation
Achieving Patient Recovery
Through Adaptive Post
Stroke Rehabilitation
New Therapeutic Method Based on Innovative Error Enhancement Technology
Robotic-based rehabilitation physical therapy for upper limb stroke patients.
deXtreme utilizes adaptive instinctive corrective force responses to shorten recovery time.
We let go of the reliance on cognition and harness the body’s ability to adapt to changes in environmental forces in order to shorten recovery time from stroke and other neurological injuries.
Introducing New Approach to Motor Learning
Our innovation lies in the combination of a new approach to motor learning and groundbreaking technology. A unique robotic device applies motor error enhancement forces that operate during practice in a virtual environment. The forces stimulate the body’s instinctive adaptive response, which does not require the use of cognition to correct the movement.
The setting of stroke patients in a simulated environment enhances patient motivation and participation. The completion of “games” (tasks) is a great indicator for the patients that they are progressing in the treatment and are on their way to recovery.
The system does not rely in any way on guidance – manual or robotic. Rather, the error enhancement forces lead the patient to perform the correct movement.
Our physical therapy treatments for upper limb stroke patients improve position accuracy and stability while increasing range of motion. In fact, therapy time is shortened by up to 50%, compared to traditional therapies and other technologies. Patients using deXtreme demonstrate 100% improvement in motor results compared to other patients.
Motor Improvement by Error Enhancement Forces - How Does It Work?
- The brain predicts forces that are necessary for an upcoming movement and programs muscle activation accordingly
- When force prediction is incorrect, movement errors drive adaption of the motor commands
01
The patient performs a movement with an error; the system is measuring the movement.
02
The system applies
an error-enhancing force.
03
Adaptive instinctive force response by the patient corrects the enhanced error by the system.
04
The system removes the applied force, resulting in error-free movement performed by the patient.
