What to Expect During a Lameness Exam
A good lameness exam is part detective work, part biomechanics lesson, and part honest conversation about your horse’s future. From the veterinarian’s side, the goal is to identify where your horse is uncomfortable, why it is happening, and what we can realistically do about it. From your side as the owner or rider, it helps to know what the day will look like so you can plan ahead and feel prepared.
This overview walks through a typical lameness exam for a riding horse and explains what you and your horse can expect at each stage.
Before The Appointment
Your veterinarian will usually start gathering information before they ever see the horse move. You may be asked about:
• Signalment and use (age, breed, discipline, level of work)
• How long you have noticed a problem and how it started (sudden vs gradual)
• Whether the lameness is better or worse with work, rest, or footing changes
• Any history of injuries, previous imaging, or treatments
• Current medications or supplements, especially pain relievers
It is very helpful to bring:
• The saddle, bridle, and boots you normally use
• Any recent farrier records or information about shoeing changes
• Videos of the horse moving at home or at shows, if available
Most veterinarians prefer that horses are not given pain medications (such as phenylbutazone or firocoxib) for 24–48 hours before a lameness exam, unless there is a medical reason to continue them. This allows us to see the lameness more clearly.
Initial Physical And Hoof Exam
The visit typically starts with a general physical and limb exam. Your veterinarian may:
• Assess body condition, muscling, and overall symmetry
• Check vital signs and look for signs of systemic illness
• Palpate muscles, tendons, ligaments, and joints for heat, pain, swelling, or thickening
• Use hoof testers to check for sensitivity in the feet
• Evaluate hoof balance, shape, and shoeing, often in collaboration with your farrier later on
This hands-on assessment can already give important clues, such as a sore digital flexor tendon, heat in a joint, a stinging foot, or a back or pelvic component to the lameness.
Watching The Horse Move
The next step is to see how the horse moves at different gaits and on different surfaces. Depending on your facilities and the horse’s discipline, this can include:
• Walking and trotting in hand on a straight line
• Trotting on a circle on soft and/or hard footing
• Lungeing in both directions
• Watching the horse under saddle if that is when the problem is most obvious
Your veterinarian will be watching for:
• Head bob (often associated with forelimb lameness)
• Hip hike or drop (often associated with hindlimb lameness)
• Shortened stride length or toe dragging
• Changes in tracking up and symmetry behind
• Worsening or improvement of the lameness on a circle or certain surfaces
In some practices, a lameness locator or inertial sensor system may be used as an additional tool to quantify asymmetry, but it does not replace the clinical exam.
Flexion Tests And Other Manipulations
To further pinpoint the source of discomfort, the veterinarian may perform flexion tests or other limb manipulations. This typically involves:
• Holding a joint or region in flexion for a set period of time
• Immediately trotting the horse off in a straight line
• Scoring any increase in lameness that occurs after the flexion
Flexion tests are not perfect and can sometimes exaggerate mild issues, but when interpreted in context they can help localize pain to regions such as the distal limb, fetlock, hock, or stifle.
Other manipulations may include stressing specific structures (for example, wedging the heels or toes, or trotting on a small circle) to see how the gait changes.
Diagnostic Analgesia (Nerve And Joint Blocks)
When basic workup localizes the lameness to a general area but not a specific structure, the next step is often diagnostic analgesia. This is one of the most important tools in lameness workups.
Diagnostic analgesia involves:
• Injecting a small amount of local anesthetic around nerves (nerve blocks) or into joints or tendon sheaths (intra-articular blocks)
• Waiting a short period for the anesthetic to take effect
• Repeating the trot or lunge exam to see if the lameness improves
By starting low in the limb and working upward in a systematic way, your veterinarian can identify the region that, when desensitized, causes the horse to go sounder. This helps avoid guessing and directs imaging to the right place.
Many horses tolerate blocks very well, but mild sedation may be used for safety, especially in excited or anxious horses.
Imaging: Radiographs And Ultrasound
Once the painful region is identified, the next question is “What, exactly, is wrong here?” That is where imaging comes in. Depending on findings and facilities, the veterinarian may recommend:
• Radiographs (x-rays) to look at bone, joint spaces, and areas of calcification or remodeling
• Ultrasound to evaluate soft tissues such as tendons, ligaments, and joint capsules
• In some referral settings, advanced imaging such as MRI, CT, or nuclear scintigraphy for complex or multi-limb cases
Not every lameness exam progresses to advanced imaging, but even basic radiographs and ultrasound can significantly refine the diagnosis and help with prognosis and treatment planning.
Discussion, Diagnosis, And Treatment Plan
After the exam, blocks, and imaging, your veterinarian will synthesize all of the information and discuss the likely diagnosis or list of possibilities. This is often the most important part of the day for owners, because it connects the technical findings to practical decisions.
Topics covered commonly include:
• The specific structures involved and how badly they are affected
• Whether the condition is acute, chronic, or degenerative
• Expected prognosis for soundness and level of work
• Immediate recommendations (rest, medications, shoeing changes, injections, or referral)
• A longer-term management plan, including conditioning, footing, body weight, and follow-up
In many cases there is some uncertainty, and your veterinarian may outline “best case,” “expected,” and “worst case” scenarios to help you make informed choices.
How Long It Takes And How To Prepare
The length of a lameness exam can vary widely. A very straightforward, mild, single-limb lameness may be evaluated in an hour or two. A complex, multi-limb or performance-limiting issue that requires multiple blocks and imaging can take several hours or even more than one visit.
To help the day go smoothly, you can:
• Have the horse clean, halter-broke, and accustomed to being trotted in hand
• Bring appropriate tack and a competent rider if under-saddle evaluation is needed
• Ensure your footing areas (aisle, driveway, arena) are safe for trotting and lungeing
• Be prepared to discuss budget and priorities so the workup can be tailored to your situation
Remember that the purpose of the exam is not just to label the problem, but to generate a plan that makes sense for you and your horse. Clear communication and realistic expectations go a long way toward a satisfying outcome.
