Pre-Purchase Exams
The AAEP's April 2026 pre-purchase examination guidelines introduced updated requirements for lameness grading notation, flexion test documentation, and buyer-seller communication standards. For equine vets who perform PPEs regularly, each change carries a direct documentation workflow implication, and most existing record systems are not built to handle them out of the box.
In short: the update requires recording lameness grades on the numeric 0-5 scale, not narrative alone; documenting flexion tests by limb and duration as discrete entries; and keeping written proof that significant findings were discussed with buyers or sellers. Most generic practice management systems lack these structured fields, which forces vets to reconstruct AAEP-compliant records by hand after each exam.
Key takeaways
StableTrack is an equine-specific practice management platform built by Asteris, a veterinary software company. It includes a dedicated PPE (pre-purchase examination) Workflow module aligned to AAEP (American Association of Equine Practitioners) examination standards. The April 2026 AAEP update introduced explicit documentation language around lameness grading consistency and flexion test interpretation, topics that were previously left to individual practitioner discretion.
What exactly did the AAEP change in April 2026?
The April 2026 update to the AAEP's pre-purchase examination framework introduced three specific documentation changes that directly affect how equine vets record and communicate PPE findings. These changes standardize three areas that were previously left to practitioner discretion.
Lameness grading documentation. The updated guidelines now require recording the specific AAEP lameness grade (0 through 5) with consistent numeric notation, rather than narrative descriptors alone. A finding recorded as "mild left forelimb lameness" without a numeric grade is no longer considered sufficient under the updated standard. The 0-5 scale must be explicitly selected for each limb and gait evaluated.
Flexion test documentation. The guidelines now call for explicit notation of limb, duration in seconds, and response grade for every flexion test performed. Previously, many practitioners noted flexion results in shorthand or bundled them into general observations. The update separates flexion findings into a discrete, structured record element with one entry per test.
Buyer-seller communication standards. The April 2026 language adds clarity around how findings are communicated to both buyer and seller, including a written record that the vet discussed significant findings with the appropriate party. This is less a clinical requirement than a medico-legal one, but it demands documentation structure that many systems do not provide.
Why do these changes create a documentation problem for most equine practices?
Most equine vets already apply lameness grades and document flexion tests with clinical care, but their practice management software does not support the structured fields the April 2026 guidelines require. This forces vets to bridge the gap manually, introducing inefficiency and inconsistency across reports.
Generic veterinary practice management systems were built for small animal or mixed practice workflows. They do not carry discrete lameness grade fields mapped to the AAEP 0-5 scale, structured flexion notation by limb and duration, or communication disclosure checkboxes. A vet using a general-purpose system has to reconstruct an AAEP-compliant record manually, every time.
The record isn't just your clinical note anymore. It's a document the buyer's attorney may read.
That is not a hypothetical. As PPE standards tighten and performance horse transactions grow in value, documentation quality has become a liability question as much as a clinical one. A report that does not reflect current AAEP standards will look dated, and in a high-value transaction, dated documentation raises questions regardless of enforcement timelines.
How does each April 2026 change translate into a specific workflow requirement?
Each AAEP documentation requirement maps directly to a software feature the examining vet needs in order to create compliant records without manual bridging.
- Lameness grade must be numeric (0-5). You need a discrete grade field per limb and per gait, which means a structured input field rather than free text.
- Flexion tests by limb, duration, and response. You need one structured entry per test, which means a per-limb flexion log with response options.
- Communication disclosure. You need a written record of the buyer or seller discussion, which means checkboxes or an attestation field in the exam record.
- Imaging in PPE scope. You need to link radiograph findings to the PPE record, which means integration between imaging notes and the PPE form.
- Consistent report format. You need reproducible output that buyers can read, which means a templated PDF export aligned to the AAEP format.
Each item is a feature requirement, not a nice-to-have. If the software does not carry these fields natively, the vet fills the gap manually, which costs time barnside and introduces inconsistency across reports.
How does StableTrack handle the updated April 2026 requirements out of the box?
StableTrack's PPE Workflow, part of the Asteris equine practice management platform, was built specifically for AAEP-aligned pre-purchase examinations. It includes native support for every field the April 2026 update requires, removing the need for manual workarounds.
Structured Lameness Grading
The workflow includes discrete AAEP 0-5 lameness grade fields per limb and per gait surface. The vet selects the grade from a structured input, the AI assistant drafts the associated language, and the vet reviews it before the record is finalized. No numeric grade is left to narrative interpretation.
Per-Limb Flexion Logging
Flexion tests are logged as individual entries: limb, duration in seconds, and response grade. The structure mirrors the April 2026 language directly. Vets working barnside without reliable signal can complete flexion entries offline, and records sync when connectivity returns.
Henneke Body Condition Scoring
The PPE Workflow includes integrated Henneke BCS fields, scored 1-9 with visual reference. This is part of the exam record, not a separate note, making body condition findings auditable and consistent across exams.
AI-Drafted Risk Summaries
After the exam fields are completed, StableTrack's AI assistant drafts a structured risk summary, flagging findings that may warrant buyer discussion or further diagnostics. The vet reviews the summary, edits as needed, and approves it. The AI surfaces patterns, the vet makes every clinical and communication decision. This aligns directly with the April 2026 communication disclosure requirement by creating a reviewable, timestamped summary.
Templated Output
The completed PPE record exports as a formatted report with consistent field structure. Buyers, sellers, and referring vets receive the same layout every time, which supports the communication standard the April 2026 update formalizes.
What does the StableTrack PPE Workflow include?
- AAEP lameness grade fields: discrete 0-5 input per limb and per gait, not free text.
- Flexion test log: per-limb entries with duration and response, structured to match April 2026 language.
- Henneke BCS: integrated 1-9 scoring with visual reference inside the exam form.
- AI risk summary: drafted by the AI assistant, reviewed and approved by the vet before any record is saved.
- Communication disclosure: checkboxes for buyer and seller discussion, timestamped in the record.
- Offline-capable: the full PPE workflow functions without signal and syncs automatically when back in range.
- Templated PDF export: a consistent report format readable by buyers, sellers, and attorneys.

Is the April 2026 standard already expected in practice, or is there a grace period?
The April 2026 update does not carry an enforcement deadline in the way a regulatory rule would, but that distinction matters less than it sounds. The AAEP sets professional standards, not legal mandates. However, buyers, their vets, and their legal representatives reference AAEP guidelines when evaluating PPE reports, and a report that does not reflect current standards will look dated and raise liability questions in high-value transactions regardless of enforcement timelines.
Vets who align their documentation now are ahead of the curve. Vets who wait until the standard is universally expected may find themselves retrofitting records on past exams. The equine practice management software question is not just about efficiency, it is about record quality under scrutiny.
FAQ
What did the AAEP change in its April 2026 pre-purchase examination guidelines? The April 2026 AAEP update tightened documentation requirements in three areas: lameness grades must now use the numeric 0-5 scale rather than narrative descriptors alone; flexion tests must be recorded by limb, duration in seconds, and response grade as discrete entries, one entry per test; and vets must include a written disclosure that significant findings were communicated to the appropriate buyer or seller. These changes standardize how clinical findings are recorded and shared.
Does my practice management software need to be updated to meet the new AAEP PPE standard? Most generic veterinary practice management tools lack the structured fields the April 2026 guidelines require. If your current system does not have discrete AAEP lameness grade fields on the 0-5 scale, per-limb flexion logging with duration and response options, and a communication disclosure field, you are likely bridging the gap with manual narrative or handwritten notes. That creates inconsistency across reports and adds time after the exam. AAEP-specific software carries these fields natively.
What is Henneke BCS and why is it part of a PPE record? The Henneke Body Condition Score is a standardized 1-9 scale for assessing equine body fat and condition, developed at Texas A&M University. It is routinely included in pre-purchase examinations because condition score can indicate nutritional history, metabolic issues, or workload management, all factors relevant to the horse's fitness for the buyer's intended use. Recording it as a structured field rather than a narrative comment keeps the finding consistent and auditable.
How does AI fit into PPE documentation without overstepping the vet's clinical role? In StableTrack's model, the AI assistant drafts the structured PPE note and risk summary based on the fields the vet completed during the examination. The vet reviews every element, edits as needed, and approves the record before it is finalized. The AI surfaces discrepancies and flags notable findings, it never assigns a diagnosis, a lameness grade, or a clinical recommendation. Every clinical and communication decision belongs to the examining veterinarian.
Can equine vets use StableTrack for PPE documentation in areas with poor cell signal? Yes. StableTrack is offline-capable, so the full PPE workflow, including AAEP grade fields, flexion logging, Henneke BCS, and the AI draft function, operates without internet connectivity. Records sync automatically when the device reconnects. This is designed for ambulatory and field vets working at barns and sale facilities where signal is unreliable or absent.
