Lameness is defined as what?

• A. A gait abnormality resulting in a lack of symmetry in the stride pattern, caused by pain or mechanical restrictions
• B. A mild limp that disappears with rest
• C. A general lack of coordination
• D. A reluctance to move any limb

Answer: (A)

Lameness is an abnormal gait with asymmetry in the stride caused by pain or mechanical restriction in a limb. This definition centers on a visible change in how the animal walks, reflecting that one limb is being offloaded or limited due to discomfort or structural restriction. The emphasis is on the gait pattern itself rather than just a general limp that might disappear with rest, lack of coordination, or a broad reluctance to move a limb. A mild limp that resolves with rest can occur but doesn’t define lameness, and lack of coordination points to ataxia rather than a limb-specific gait abnormality.
