Product - deXtreme™
Imagine a person hiking through the woods, carrying a heavy 10kg backpack. After a long hike this person sits down for a short rest, and removes the bag from his back. He immediately gets a feeling of elevation.
The reason for this elevation feeling is that the body still thinks it’s carrying the backpack, the back muscles continue pushing upwards and so this elevation feeling lingers for a few good seconds.
This phenomenon is called an adaptive reaction of the body. BioXtreme has harnessed this bio-mechanical principal for its unique product to rehabilitate stroke victims.
A person suffering from a stroke and in need of motor rehabilitation usually performs in three ways a task of moving an object from point A to point B:
1. Right or left deviation from the path
2. Upwards or down deviation from the path
3. A Weak or too strong movement
Current rehabilitation therapies auto-correct the movement in a controlled manner until the patient reaches the “correct” movement level, each patient according to his/her limitations.
BioXtreme has developed a unique patent-protected technology based on adaptive or intuitive learning principal. Our robotic system performs an error enhancement process, so if for example the patient’s movement deviated to the left, the system will further “extreme” it towards left.
The body’s adaptive reaction or intuitive learning will return the hand to the correct path. Since the robot is working on three hinges, all three sorts of deviations can be corrected. In this manner, automatic rebuild of motion capability and dexterity through instinctive learning is achieved.
This ground breaking technology is patent-protected, was tested and proven in three clinical trials in Israel. An additional trial is planned in the Netherlands during 2020. The trials results prove that neurorehabilitation time for stroke patients can be shortened by up to 30%-50% and motoric results improve in the same ratio.
deXtreme™ 3.0 has completed development stages and is market ready as of January 2020.
The technology behind deXtreme™ is based on the following components:
- A VR based application in 3 dimensions to create the movement exercising scenes.
- A robotic arm, which contains various sensors to measure movement performances and; 3 motors to enable controlled movements and error enforcements in 3 dimensions.
- Algorithms to calculate predefined patient’s correct motor and patient’s motor errors.
- Error enhancement algorithms.
- A realtime control system for commanding the motors, based on the calculated measured data and the error enhancement algorithm outcomes.
