Low-Intensity Electrical Stimulation for Bone Growth, Avoiding Contraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current treatments for osteoporosis, such as medications, are insufficient in strengthening bones and preventing fractures while causing undesirable side effects, and existing electrical stimulation methods are inefficient or cause muscle contractions.
Innovation Solution
A method and device using a low-intensity electrical current to directly stimulate bone cells without causing muscle contraction, employing a biphasic current with specific frequency and intensity ranges to promote bone growth and density.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If high-intensity electrical stimulation is used to promote bone growth, then bone healing effect is improved, but muscle contraction occurs causing patient discomfort
Solution Approach 1:
The patent applies parameter changes by precisely controlling electrical stimulation parameters including low intensity (0.01-10 mA), specific frequencies (1-1000 Hz), and pulse durations (10-1000 ms) to achieve bone stimulation while avoiding muscle contraction thresholds, thereby resolving the contradiction between effective bone healing and patient comfort
2Strength
If traditional osteoporosis medications are used, then bone strength is improved, but undesirable side effects and atypical fractures occur
Solution Approach 1:
The patent replaces pharmacological treatment with physical electrical stimulation therapy, substituting chemical-based medication with a physical field-based approach that directly stimulates bone cells through electrical currents, thereby achieving bone strengthening without the harmful side effects and atypical fractures associated with traditional drugs
3Reliability
If externally applied electrical stimulation is used to improve bone healing, then bone growth is promoted, but the treatment complexity and intensity requirements increase
Solution Approach 1:
The patent simplifies treatment complexity by establishing specific parameter ranges for electrical stimulation including low intensity (0.01-10 mA), controlled frequencies (1-1000 Hz), and defined pulse durations (10-1000 ms), making the device easier to operate and more accessible while maintaining effective bone growth promotion

AI summary
A method for preventing bone loss. promoting bone growth, or healing a bone in a subject includes directly electrically stimulating bone cells with a low-intensity electrical current avoiding muscle contraction, administering the electrical stimulation with the low-intensity electrical current in a manner which prevents bone loss or heals bones. The bone cells are selected from a group consisting of arms, legs, pelvis, ribs, trunk. head, spine, wrist, ankle and whole body. The electrical stimulation with the low-intensity electrical current provides at least one of the following benefits: maintenance of bone quality or bone health prevention of osteoporosis, treatment of osteoporosis, promotion of bone healing, prevention of fractures, treatment of fractures, treatment of spinal fusion, and treatment of spinal-cord iniury.
