Peripheral Nerve Stimulation With ML Feedback for Tremor Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current treatments for essential tremor, such as medications and deep brain stimulation, are either ineffective for many patients or carry significant side effects and risks, highlighting a need for alternative, non-invasive methods to reduce tremor amplitude without surgical intervention.
Innovation Solution
A peripheral nerve stimulation device delivers electrical or chemical stimuli to sensory nerves to modify abnormal neural network dynamics, reducing tremor by altering brain circuitry without invasive surgery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If deep brain stimulation is used to treat essential tremor, then tremor amplitude reduction is achieved (up to 90%), but surgical risks and invasiveness increase
Solution Approach 1:
The patent introduces peripheral nerves as an intermediary target between the stimulation device and the tremor source. Instead of directly stimulating the brain (deep brain stimulation), the device stimulates peripheral nerves that project to the brain, using these nerves as a mediator to indirectly modulate tremor-generating neural circuits. This approach achieves tremor reduction while avoiding direct brain surgery.
Solution Approach 2:
The patent extracts the stimulation target from the brain and relocates it to peripheral nerves. By taking out the stimulation site from the invasive brain region and placing it on accessible peripheral nerves, the system achieves the same therapeutic effect (tremor reduction) without the harmful surgical risks associated with brain penetration.
2Reliability
If medications are used to treat essential tremor, then tremor amplitude is reduced (by 50% in 60% of patients), but side effects increase
Solution Approach 1:
The patent replaces the chemical mechanism of medications with an electrical/neural mechanism. Instead of using pharmaceutical drugs that chemically affect the nervous system and cause side effects, the device uses electrical stimulation of peripheral nerves to directly modulate neural circuitry. This substitution achieves tremor reduction through a physical/neural mechanism rather than chemical action, thereby eliminating drug-related side effects.
3Ease of operation
If peripheral nerve stimulation is used to treat essential tremor, then non-invasive treatment is achieved, but tremor reduction effectiveness may be limited
Solution Approach 1:
The patent incorporates feedback mechanisms where the system monitors tremor characteristics and adjusts stimulation parameters accordingly. The device detects tremor frequency, amplitude, and other features, then uses this information to dynamically adjust the stimulation parameters to optimize tremor reduction. This feedback loop ensures that the non-invasive peripheral nerve stimulation achieves effective tremor control by continuously adapting to the patient's specific tremor profile.
Solution Approach 2:
The patent employs dynamic stimulation patterns that adapt to changing tremor conditions. Rather than using static, fixed-frequency stimulation, the system dynamically adjusts stimulation frequency, intensity, and timing based on real-time tremor detection. This dynamic approach enhances the effectiveness of non-invasive peripheral nerve stimulation by optimizing the stimulation parameters for each moment's tremor characteristics.
