When A Horse Is Moving Concussion In The Hindlimb Is Mostly Absorbed?
The pastern joint absorbs most of the impact transmitted upward from the foot. A sloping pastern has more concussion-absorbing qualities than a short, steep pastern. An ideal angle of the forelimb pastern is approximately 45 degrees.

What part of the hoof absorbs concussion?
Much of the concussion of movement is absorbed by the hoof and beneath the pedal bone is the digital cushion, which absorbs and dissipates the weight from the short pastern. This mechanism widens the lateral cartilage, which spreads the heel, thus absorbing the concussive forces over a greater surface area.
What is a concussion in horses?
Concussion is the force sent vertically up the leg each time a horse’s hoof strikes the ground. Concussion is a major factor in lameness. Factors that affect the concussive force on the horse’s legs are: The angle, surface, and hardness of the ground on which the horse is travelling.
How does horse conformation affect movement?
Any conformational flaw causes deviations in where the horse absorbs concussion. Conformational defects affect the horse’s way of moving and can also lead to future lameness due to excessive stress placed on certain areas of the body during athletic movements.
What is concussive laminitis?
Concussive laminitis (or road founder), is when horses are subjected to fast or prolonged work on hard surfaces. They may develop laminitis as a result of trauma to the laminae, particularly if their horn quality is poor.
What part of the horses foot acts as a shock absorber?
The digital cushion is the area below the coffin bone towards the back of the hoof. It does exactly what the name implies: it is a cushion of cartilaginous material with some “give,” acting as one of the main shock absorbers in the hoof.
What body parts are affected by a concussion?
Overview. A concussion is a traumatic brain injury that affects your brain function. Effects are usually temporary but can include headaches and problems with concentration, memory, balance and coordination. Concussions are usually caused by a blow to the head.
What are the 3 stages of a concussion?
Below are the three grades of concussion: Grade 1, Mild: Symptoms that last less than 15 minutes and entail no loss of consciousness. Grade 2, Moderate: Symptoms that last for longer than 15 minutes and involve no loss of consciousness. Grade 3, Severe: The person loses consciousness.
What are 4 effects of a concussion?
Drowsiness or inability to wake up. A headache that gets worse and does not go away. Slurred speech, weakness, numbness, or decreased coordination. Repeated vomiting or nausea, convulsions or seizures (shaking or twitching).
How does a concussion go away?
Rest is very important after a concussion because it helps the brain to heal. You’ll need to be patient because healing takes time. Only when the symptoms have reduced significantly, in consultation with your doctor, should you slowly and gradually return to your daily activities, such as work or school.
What are the stages of horse movement?
Natural Gaits There are five natural gaits of horses. These natural gaits include the walk,
What are three conformational faults in a horses legs?
Conformational faults such as toed in and toed out commonly are passed down from generation to generation. Back-at-the-knee (calf-knee), offset (bench) knee, tied-in below the knee, sickle-hocked, and straight-behind conditions appear to be highly heritable.
What causes hind end weakness in horses?
The most common reason that a horse is weak on one
How do you treat a concussion in a horse?
Give the horse an easy few days to see if the swelling and heat subside. ‘ Cold therapy can be very useful in the early stages of concussion. ‘Any acute injury is likely to benefit from cooling and cold treatment.
Can a horse recover from a rotated pedal bone?
Although significant rotation has been associated with a poorer prognosis, there is evidence of horses with rotation of up to 30° being corrected. However, if there is significant rotation of the pedal bone and treatment is not instigated, the disease can progress.
What are the stages of laminitis in horses?
There are 4 phases of laminitis: the developmental phase, the acute phase, the subacute phase, and the chronic phase. The developmental phase is initiated when the horse experiences or comes in contact with one of the predisposing factors.
What ligament acts as a shock absorber?
2.3. 2 Cartilage. Cartilage is the tough yet flexible avascular connective tissue covering the surfaces of two bones in a joint where it is responsible for fluidic movement of one bone over another and also act as a shock absorber.
Which arch of the foot is primarily responsible for shock absorption during walking?
The medial longitudinal arch also has an important role in shock absorption and propulsion during walking, running and jumping. The arch acts like a springboard, as its anterior pillar is the point of take-off during these activities.
Where are the most sensory nerve endings on the horse’s body?
The sensitivity of the skin is thought to vary across the body of the horse as the distribution of sensory nerve receptors vary, with areas such as the muzzle, neck, withers, coronets, shoulders, lower flank and rear of the pastern typically being most sensitive (120).
What happens when a concussion occurs?
Concussions stretch and bruise nerves and blood vessels and cause chemical changes in your brain that result in a temporary loss of normal brain function. A single concussion usually doesn’t cause permanent damage to your brain. Multiple concussions over a lifetime may result in structural changes in your brain.
What tissue is damaged in a concussion?
Concussions. As concussions notably impact brain tissue and often result in damage to brain function, they are considered soft tissue injuries. Though there are many causes of concussions, this soft tissue injury most commonly affects athletes or individuals involved in contact sports, such as football and boxing.
