Somatosensory Hoffmann Reflex (H-Reflex) Skill

License: Apache-2.0 Python 3.10+ Zero Dependencies MCP Protocol Ready OpenClaw Certified

Zero-dependency sovereign personal agent skill for non-invasive evaluation of Hoffmann Reflex (H-Reflex) $H_{max} / M_{max}$ recruitment ratio, reflex onset latency, and spinal alpha motoneuron pool neuromuscular excitability.

Features

  • Deterministic Math: Pure Python standard library implementation with zero external dependencies.

  • Electroneuromyography (ENMG) Standards: Formulates Hmax/Mmax recruitment curves, monosynaptic transmission latency, and presynaptic inhibition.

  • Central Neuromuscular Fatigue: Highly sensitive detection of spinal motoneuron exhaustion vs peripheral muscle fatigue.

  • Model Context Protocol (MCP): Native JSON-RPC tool integration for LLMs and autonomous agents.

Quickstart

from client import SomatosensoryHReflexClient

client = SomatosensoryHReflexClient()
result = client.evaluate_h_reflex(
    h_max_amplitude_mv=4.2,
    m_max_amplitude_mv=7.8,
    h_latency_ms=30.4
)
print("Hmax / Mmax Ratio:", result["h_m_ratio_pct"], "%")
print("Spinal Excitability Score:", result["spinal_excitability_score"])
print("Classification:", result["classification"])
