Neuromodulation Stimulation for Differential Physical Therapy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current neuromodulation techniques face challenges in targeting specific anatomical regions due to the semi-permanent nature of surgical interventions and the imprecision of chemical agents, and they often fail to account for differential responses of target regions to stimulation, limiting their effectiveness in neurological conditions such as Parkinson's disease and osteoarthritis.
Innovation Solution
The method involves providing stimulation to the central nervous system to modulate signals sent to or from target regions, assessing differential responses, and providing focused physical therapy based on these responses, using a combination of electrical and mechanical fields to enhance treatment efficacy, particularly in regions that are more or less responsive to stimulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If surgical intervention is used for neuromodulation, then the treatment can be precisely targeted to specific nerve tracts, but the semi-permanent nature of surgery leaves little room for later adjustment and optimization
Solution Approach 1:
The patent employs dynamic, reversible neuromodulation techniques that allow treatment parameters to be adjusted in real-time based on patient response. Unlike permanent surgical interventions, the methods enable clinicians to modify stimulation intensity, frequency, and duration to optimize therapeutic effects while minimizing side effects.
Solution Approach 2:
The invention utilizes controllable stimulation parameters that can be systematically varied to achieve desired neuromodulatory effects. By changing electrical or mechanical stimulation parameters, the treatment can be tailored to individual patient needs and adjusted over time as clinical outcomes are monitored.
2Ease of operation
If chemical agents or medications are used for neuromodulation, then the treatment can be easily administered, but the titration process is slow and imprecise for achieving desired effects on specific targets
Solution Approach 1:
The patent replaces chemical medication delivery with physical stimulation methods (electrical or mechanical) that can be precisely controlled and targeted. This substitution eliminates the slow titration process associated with chemical agents while maintaining ease of administration through non-invasive or minimally invasive delivery systems.
Solution Approach 2:
The invention uses stimulation devices as intermediaries between the operator and the target nervous system tissue. These devices provide precise spatial and temporal control over neuromodulation effects, enabling accurate targeting of specific nerve tracts or brain regions without the diffusion and delay inherent in chemical delivery.
3Device complexity
If uniform physical therapy is provided to all target regions, then the treatment protocol is simple to implement, but it fails to account for differential responses of target regions to stimulation
Solution Approach 1:
The patent implements differential physical therapy protocols tailored to specific target regions based on their individual responses to stimulation. Rather than applying uniform treatment across all regions, the method adjusts therapy intensity, type, and duration to match the unique characteristics and responsiveness of each stimulated area, thereby optimizing overall treatment effectiveness.
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
This approach allows for improved therapeutic outcomes by tailoring physical therapy to regions with varying responses to stimulation, leading to synergistic effects that enhance treatment efficacy beyond what either method could achieve alone, with lasting impacts on neurological conditions like Parkinson's disease and osteoarthritis.
Implementation Method 1
Neuromodulation is the control of nerve activity, and is usually implemented for the purpose of treating disease. Neuromodulation may be accomplished with surgical intervention, such as cutting an aberrant nerve tract. However, the semi-permanent nature of a surgical procedure leaves little room for later adjustment and optimization.
Implementation Method 2
Long-term potentiation (LTP) involves the process of establishing an association between the firing of two cells or groups of cells. For instance, if an axon of cell A is near enough to excite a cell B and repeatedly or persistently takes part in firing cell B, an increase in the strength of the chemical synapse between the cells takes place such that A's efficiency, as one of the cells firing B, is increased.
Implementation Method 3
An opposite effect, long-term depression (LTD), has also been established. LTD is the weakening of a neuronal synapse that lasts from hours to months.
Implementation Method 4
Neuromodulation may also be accomplished using energy-delivering devices. The stimulation may be applied invasively, e.g., by performing surgery to remove a portion of the skull and implanting electrodes in a specific location within brain tissue, or non-invasively, e.g., transcranial direct current stimulation (tDCS) and transcranial magnetic stimulation (TMS).
Implementation Method 5
The stimulation may act to modulate the plasticity of tissue (e.g., long term potentiation and/or long term depression).

AI summary
The invention generally relates to methods for guiding physical therapy to a subject. In certain embodiments, methods of the invention involve providing stimulation to a subject's central nervous system to modulate one or more signals sent to or from a plurality of target regions of the subject. Methods of the invention further involve assessing the response of the plurality of target regions to the stimulation to determine if there is a differential response among the target regions to the stimulation, and providing focused physical therapy to at least one of the target regions based on the assessment of the response of the plurality of peripheral target regions to the stimulation.
