Features

• Deterministic Math: Pure Python standard library implementation with zero external dependencies.
• Clinical Neuro-Otology Standards: Implements validated algorithms for high-frequency angular canal excitation.
• Dynamic Visual Acuity & Motion Sickness Stratification: Direct quantification of retinal slip and vestibular compensation.
• Model Context Protocol (MCP): Native JSON-RPC tool integration for LLMs and autonomous agents.

Quickstart

from client import VestibularHeadImpulseClient

client = VestibularHeadImpulseClient()
result = client.evaluate_vhit(
    head_velocity_deg_s=195.0,
    eye_velocity_deg_s=188.0,
    overt_saccades_count=0
)
print("VOR Gain:", result["vor_gain"])
print("Classification:", result["classification"])
