Area of Science:

Neurology
Biomedical Engineering
Medical Diagnostics

Background:

Needle electromyography (EMG) is crucial for diagnosing neuromuscular disorders.
Subjective assessment of EMG interference patterns (IP) can lack objectivity.
Quantifying IP features could enhance diagnostic accuracy.

Purpose of the Study:

To develop an "Augmented Intelligence" (AI) method for objective interference pattern (IP) analysis in electromyography (EMG).
To quantify key IP characteristics including fullness, discreteness, amplitude, pitch, and motor unit firing rate (FR).
To mimic subjective EMG assessment with quantitative data for improved objectivity.

Main Methods:

Analysis of IP recordings from 20 control subjects and patients with neuropathy/myopathy.
Categorization of IP into low, intermediate, and full based on visual appearance.
Definition of reference values (RVs) and a "fence" pattern for discreteness and amplitude.
Exclusion of technical artifacts from the analysis.

Main Results:

A single set of RVs proved satisfactory across 119 muscles in control subjects.
Neuropathy patients showed intermediate/low IP, high amplitude, fence pattern, low pitch, and high FR.
Myopathy patients exhibited a full pattern with low amplitude and high pitch.

Conclusions:

The developed algorithm provides quantitative data, augmenting the electromyographer's analysis.
Online implementation can guide operators without increasing procedure time.
Quantitative measurements can be incorporated into reports to support findings.
