AAEP Equine Lameness Grade Lookup

Bounded offline reference: AAEPlameness grades0–5are ordinal clinical descriptors, not a direct linear measurement of tissue injury. Source: AAEPlameness scale. No automatic gait diagnosis, localization or permission to exercise a lame horse. Explicit topic keys: 0, 1, 2, 3, 4, 5. Not a full/current corpus, diagnosis, treatment recommendation or safety certification.

Description

The AAEP lameness scale uses ordinal grades from zero through five to describe assessed observations.

The AAEP lameness scale uses ordinal grades from zero through five to describe assessed observations.^{[1, 2]}

A grade lookup explains a selected category without diagnosing gait or quantifying tissue injury.

When to use AAEP Equine Lameness Grade Lookup

Use this tool to read a bounded explanation for an exact reference topic. Establish the animal, measurement protocol, units and independently applicable veterinary prescription or reference.

How to use AAEP Equine Lameness Grade Lookup and understand its results

Establish the animal, measurement protocol, units and independently applicable veterinary prescription or reference.
Enter topic, using the field meanings and rules below, then run the tool.
Read result.text for the exact selection. Use its qualifications when relating the explanation to your actual production or assessment.
Correct any reported input issue and run again. Before using a successful result, check the stated units, signs, reference scope and observation coverage.

Input field	Meaning	Value type	Requirement
topic	Topic	string	Required

Choose one exact topic token from the table. The implementation looks up the stored value and returns it in the documented output field. Matching is case-sensitive; unrecognized tokens fail. This is an offline bounded reference, not a live catalogue or independent attribution.

Topic token	Stored value
0	Lameness not perceptible under assessed circumstances.
1	Difficult to observe and not consistently apparent regardless of circumstances.
2	Difficult to observe at walk/trot straight but consistently apparent under certain circumstances.
3	Consistently observable at trot under all circumstances.
4	Obvious at walk.
5	Minimal weight bearing at motion/rest or inability to move.

Limitations and assumptions

The patient context, observations and applicability of any reference or prescription must be independently established. This result supplies no diagnosis, default dose, treatment selection or assessment of clinical suitability.

Missing required fields, unknown fields, wrong types and violated rules return input issues. Numeric values and outputs must be finite. Extremely large composite outputs are rejected.
