Gait and Postural abnormalities Flashcards
What is the definition of lameness?
A manifestation of pain, or a mechanical defect, that results in a gait abnormality characterised by limping
What can cause lameness?
- One or more limbs have a decrease in loading and/or change in motion
- Centre of gravity shifts towards the sound limb
- Centre of gravity oscillates more than usual
What are some features of lameness?
- Changes in stride parameters
- Changes in the limb motion pattern
- Drifting away from the lame limb
What are some features of fore limb lameness?
- Downward nod of the head during the stance phase
- lifting of the head during lamb limb stance phase
- shortening of the stride
What are some features of hind limb lameness?
assymetrical pelvis/ hip movement
shortening of the stride
bunny hopping
What is the IMU?
Inertial measurement Unit
What is the definition of dysplasia?
Deformation and/or misalignment of a joint
Commonly progresses to arthritis
What is considered to be a ‘normal symmetrical gait’?
- Walk (amble
- Trot (Pace)
What is considered to be a normal ‘asymmetrical’ gait?
Canter and Gallop
What does ‘disunited’ mean?
If leading limbs in fore and hind limbs are out of sync
What is supporting limb lameness?
Reluctance or an inability to place full weight on a limb
What is a swinging limb lameness?
Changes observed during the flight phase of a stride
* Changes in vertical movement of the pelvis
When during walking does the head go up?
Head goes up when the painful limb is on the ground
What is the most common type of laminitis?
endocrinopathic laminitis
What can laminitis lead to?
Inflammation of the laminae supporting the third phalanx
can lead to rotation and/or sinking of the third phalanx within the hoof capsule/ changes in hoof growth
