Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current neurological rehabilitation methods are inadequate for effectively restoring and improving nervous system functions, particularly in a self-administered or outpatient manner, as they often fail to target individual-specific deficits and induce plasticity in specific CNS pathways.
Innovation Solution
The development of a method and device using operant conditioning protocols to produce targeted neural plasticity in primary CNS pathways, combined with a nerve stimulation-electromyographic recording component and controller, to elicit generalized neural plasticity and improve nervous system functions such as walking and cognitive skills.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If repeated practice of motor skills (e.g., treadmill locomotion, reach and grasp actions) is used for rehabilitation, then functional improvement is expected through plasticity, but the method is seldom completely successful and fails to target individual-specific deficits
Solution Approach 1:
The patent applies local quality by using targeted transcranial magnetic stimulation (TMS) to selectively modulate specific cortical regions and neural pathways associated with particular motor deficits. Instead of general rehabilitation, the system delivers focused magnetic pulses to specific brain areas to induce plasticity changes in the relevant neural circuits, thereby addressing individual-specific deficits while maintaining reliability of functional improvement
Solution Approach 2:
The patent implements feedback through a closed-loop system that monitors neural activity (e.g., via EMG or EEG) and uses this information to adjust TMS stimulation parameters in real-time. This feedback mechanism allows the system to adapt to individual patient responses, optimize stimulation efficacy, and ensure reliable functional improvement by continuously tailoring the treatment to the patient's specific neural plasticity characteristics
2Reliability
If operant conditioning protocols are used to modify specific spinal reflex pathways, then targeted neural plasticity can be produced, but the device complexity and protocol administration complexity increase
Solution Approach 1:
The patent merges multiple functions into a single integrated device that combines TMS stimulation delivery, neural activity monitoring (EMG/EEG), and automated operant conditioning protocol execution. By integrating these components, the system reduces overall complexity despite the sophisticated conditioning protocols, as the unified device manages all functions through centralized control rather than requiring separate systems for each function
Solution Approach 2:
The patent applies self-service through automated feedback loops where the system autonomously monitors neural responses and adjusts stimulation parameters without requiring constant manual intervention. The operant conditioning protocol is automatically executed based on pre-programmed criteria, allowing the device to self-regulate and simplify administration while maintaining reliable targeted neural plasticity
3Productivity
If conventional rehabilitation methods are used, then general motor skill practice is provided, but the methods fail to induce widespread plasticity and produce limited improvement beyond practice levels
Solution Approach 1:
The patent applies parameter changes by using TMS to directly modulate neural excitability parameters in the cortex and spinal cord. By changing the physiological state of neural tissues through magnetic stimulation, the system induces widespread plasticity that goes beyond what can be achieved through repetitive motor practice alone, thereby accelerating functional recovery and producing more extensive neural reorganization
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The method significantly improves motor and cognitive skills by inducing widespread plasticity, allowing for faster and more symmetrical walking, reduced dependence on assistive devices, and enhanced performance beyond conventional practice levels, with potential applications in spinal cord injuries and other neuromuscular disorders.
