EMG-Guided Botulinum Toxin Injection for Cervical Vertigo
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current treatments for cervical vertigo caused by neck muscle dystonia are not consistently effective, as they lack precision in targeting overactive muscles, leading to variable success rates.
Innovation Solution
EMG-guided injections of botulinum toxin into selectively identified overactive neck muscles using an EMG needle assembly with a hollow needle and syringe body, allowing for precise administration based on muscle activity levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional treatments (physical therapy, medications, injections) are used for cervical vertigo, then treatment coverage is broad, but treatment effectiveness is variable and success rates are inconsistent
Solution Approach 1:
The patent applies local quality by using EMG guidance to identify and treat specific overactive neck muscles individually rather than applying uniform treatment to the entire cervical region. Each muscle is assessed for overactivity and injected with botulinum toxin based on its specific EMG findings, creating a customized local treatment approach that improves reliability while maintaining adaptability.
2Manufacturing precision
If EMG-guided botulinum toxin injections are used, then treatment precision is improved, but device complexity increases
Solution Approach 1:
The patent merges the EMG diagnostic function with the injection delivery system by using the same needle for both EMG signal acquisition and botulinum toxin injection. This integration eliminates the need for separate diagnostic and treatment devices, reducing overall system complexity while maintaining high injection precision through real-time EMG guidance.
Solution Approach 2:
The injection needle serves multiple functions: it acts as both an EMG electrode for detecting muscle overactivity and as a delivery conduit for botulinum toxin. This multi-functionality reduces the number of separate devices needed, simplifying the overall system while enabling precise, guided injections.
3Reliability
If multiple treatment modalities are applied, then treatment coverage is comprehensive, but treatment time and resource consumption increase
Solution Approach 1:
The patent performs preliminary EMG assessment to identify overactive muscles before injection, allowing for targeted treatment of only the specific muscles contributing to cervical vertigo. This preliminary identification step eliminates the need for trial-and-error treatment of multiple muscle groups, reducing overall treatment time while maintaining high success rates through precise targeting.

AI summary
A method of quickly and effectively treating cervical vertigo by using EMG-guided injections of botulinum toxin into selective dystonic neck muscles. For each treatment, EMG-guided injections are used wherein an EMG needle is injected into the muscle. An EMG test is then performed using the EMG needle to determine if the muscle is overactive. If the muscle is overactive, a measured amount of botulinum toxin is administered into the muscle using the EMG needle. Muscles that are not overactive are not administered botulinum toxin. The above procedure is conducted in various neck muscles, such as the oblique capitis superior muscle, the oblique capitis inferior muscle, the longissimus capitis muscle, the trapezius, and the levator scapula.
