Virtual Limb Feedback for Neural Pathway Reinforcement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current physical therapy techniques, such as mirror therapy and virtual reality, are inadequate for creating or reinforcing neural pathways associated with motor functions of affected limbs due to brain injuries, as they lack robust systems for linking neural patterns to target actions and providing effective virtual feedback.
Innovation Solution
A system and method that utilizes neural pattern detection to create or reinforce neural pathways by generating virtual feedback and physical assistance, where a neural pattern is detected, a target action is determined, and corresponding virtual and physical feedback is provided to simulate the action, with the virtual representation positioned to replace the real-world limb, and physical assistance is offered to aid movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mirror therapy is used to create neural pathways, then the illusion of limb movement stimulates new pathway creation, but the technique is wholly ineffectual where there is no healthy limb and provides no assisted physical feedback
Solution Approach 1:
The patent introduces an unaffected limb as an intermediary to generate neural patterns that are then applied to the affected limb through virtual feedback and physical assistance devices. This mediator allows neural pathway creation even when the affected limb cannot produce its own neural patterns
Solution Approach 2:
The system creates a virtual copy of the affected limb that can be controlled through neural patterns detected from the unaffected limb or generated by the system. This virtual representation allows patients to experience limb movement and receive feedback without requiring the actual affected limb to function
2Reliability
If mirror therapy is used to create neural pathways, then the illusion stimulates pathway creation, but the patient is fully aware of the mirror illusion which limits the effect
Solution Approach 1:
The system uses virtual reality to create a photorealistic copy of the affected limb that appears indistinguishable from reality. This virtual representation is controlled by neural patterns, creating the illusion of autonomous limb movement without the patient needing to recognize it as an illusion
Solution Approach 2:
The patent replaces the mechanical mirror system with a virtual reality-based optical system that can dynamically generate images based on neural pattern detection. This substitution allows for more convincing illusions and additional feedback modalities beyond what a simple mirror可以提供
3Reliability
If virtual reality is used to immerse patients in a virtual environment, then stimuli in the patient's brain are created, but there is no robust system for linking neural patterns to target actions and providing physical feedback
Solution Approach 1:
The system implements a closed-loop feedback mechanism where neural patterns are detected, processed to determine target actions, and then used to control virtual representations and physical feedback devices. This creates a robust linkage between neural activity and therapeutic outcomes
Solution Approach 2:
The system integrates multiple functions into a single platform: neural pattern detection, virtual reality rendering, physical feedback generation, and progress tracking. This multi-functional approach creates a robust system that addresses all aspects of neural pathway creation in one cohesive therapy delivery mechanism

AI summary
The present disclosure relates to methods and systems for providing virtual feedback of a neural pattern to create a neural pathway corresponding to an action of an affected limb of a brain injury patient. Embodiments provide for detecting a neural pattern and determining a target action associated with the detected neural pattern. A virtual feedback is generated that includes a virtual action to be performed in a virtual representation of the affected limb. In embodiments, the brain injury may prevent the affected limb from performing the target action. The virtual representation of the affected limb is superimposed over a real-world presence of the affected limb such that the virtual representation is presented to the patient in lieu of the real-world presence, and the virtual action is performed in the virtual representation, such that the virtual action is presented to the patient in lieu of the target action in the real-world.
