A rabbit's limp can stay invisible to the naked eye, a study finds
Published by Planète Pets · managing editor: Clément Lacaille · how our guides are written
Is a rabbit that's walking normally again after surgery or a sprain actually healed, or only healed in appearance? A veterinary study compared two ways of measuring lameness in rabbits, with a striking gap between what the eye sees and what a sensor detects. Our equipment recommendations are gathered in the rabbit accessories section.

Twelve rabbits, one operated knee, two assessment methods
Christina von der Ahe, Heike Marahrens, Melanie Schwarze, Nina Angrisani and Janin Reifenrath published a study in 2023, in the journal PLOS ONE, on twelve New Zealand White rabbits that underwent an artificial anterior cruciate ligament transection of the right knee, as part of a research protocol on post-traumatic osteoarthritis. Each rabbit was scored on a standard visual lameness scale, then assessed with a pressure-sensing mat measuring the load each hind paw exerted, alongside synchronised video.
The mat detects what the eye no longer can
By the twelfth week of follow-up, the visual score suggested lameness had resolved in most rabbits. The pressure mat told a very different story: almost all the animals still showed a low-grade lameness, invisible to direct observation but clearly measurable in how weight was distributed between the two hind paws. A rabbit's naturally hopping gait, unlike a dog's or a cat's, makes visual assessment especially difficult.
What this means at home
This gap is worth knowing for any owner whose rabbit is recovering from orthopaedic surgery, a fracture, or an osteoarthritis diagnosis like the one covered in our article on adjustments for an arthritic rabbit: a rabbit walking without a visible limp can still be favouring a leg for weeks after the operation. Non-slip, cushioned flooring stays useful well past the apparent end of recovery, on the same principle as the resting surfaces covered in our article on the footrest against pododermatitis.
The study's limits
The model stays experimental: lameness was surgically induced in a small group of twelve rabbits, in the context of osteoarthritis research, not naturally injured companion rabbits. The pressure mat used also isn't equipment available in routine veterinary practice. The takeaway still transfers: a gait judged normal to the naked eye doesn't guarantee a fully recovered joint.
Frequently asked questions
Can a general vet practice measure lameness with this kind of mat?
Rarely in routine practice: this equipment stays mostly confined to research settings. Repeated clinical follow-up, with palpation and observation over several weeks, remains the most accessible way to monitor recovery.
Should precautions continue even once a rabbit seems healed?
Yes, at least for the weeks following the return to a normal gait: stable flooring, limited access to jumps and cushioned bedding all stay advisable. Find all our guides on the rabbit hub.
