How this service works
Llanes 2004 Los Angeles Motor Scale (LAMS): facial droop 0 absent / 1 present + arm drift 0 absent / 1 drifts down / 2 falls rapidly + grip 0 normal / 1 weak / 2 no grip. Max 5. Point values assigned to LAPSS motor items. Deterministic published arithmetic with citation; not NIHSS, not a stroke diagnosis or thrombolysis order. magent does not examine the patient.
Output
Returns the computed LAMS total score (0–5), derived by summing facial droop (0–1), arm drift (0–2), and grip (0–2) per the Llanes 2004 published formula. Higher scores indicate more severe motor deficits.
Example use cases
Pre-hospital stroke severity screening
“A paramedic observed: no facial droop, arm falls rapidly, and no grip. What is the LAMS score?”
Large vessel occlusion triage decision support
“Compute the LAMS score for a patient with facial droop present, arm drifts down, and normal grip strength.”
Clinical documentation automation
“Record the LAMS for my stroke patient — facial droop is absent, arm drift is absent, and grip is weak. What's the total score?”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/lamsWhen to prefer
Use this endpoint when you need a deterministic, citation-backed LAMS score calculation per the Llanes 2004 protocol, particularly in pre-hospital or emergency triage workflows. Prefer this over manual arithmetic when automating stroke severity documentation or routing decisions based on LAMS thresholds.
Side effects
- Missing required query parameters (facial_droop, arm_drift, or grip) returns a validation error
- Out-of-range or invalid enum values (e.g., facial_droop=2) return a schema validation error
- Payment not provided or insufficient USDC triggers a 402 Payment Required response
