Surface Electromyography (sEMG) RMS Workload Skill

Zero-dependency sovereign personal agent skill for non-invasive evaluation of surface electromyography (sEMG) RMS amplitude, percentage MVC, median frequency fatigue, and occupational ergonomics.

Features

• Deterministic Math: Pure Python standard library implementation with zero external dependencies.
• Biomechanical Ergonomics Standards: Implements validated Jonsson static muscular load thresholds and %MVC normalization.
• Spectral Fatigue Shift Detection: Identifies localized intracellular acidification before subjective pain manifests.
• Model Context Protocol (MCP): Native JSON-RPC tool integration for LLMs and autonomous agents.

Quickstart

from client import MuscleElectromyographyClient

client = MuscleElectromyographyClient()
result = client.evaluate_emg_workload(
    emg_rms_amplitude_uv=14.5,
    mvc_reference_uv=320.0,
    muscle_group="UPPER_TRAPEZIUS"
)
print("Activation:", result["mvc_percentage"], "% MVC")
print("Classification:", result["classification"])
