Lameness

Lameness is a broad term used when pain, injury, disease or another physical problem affects a horse's normal movement or ability to use part of its body comfortably.

It can be very obvious, with a horse clearly protecting one limb or being reluctant to bear weight on it. But it can also be extremely subtle — perhaps appearing only as stiffness, uneven movement, altered rhythm, reluctance to turn or an unexplained reduction in performance.

Lameness is not a single disease. It tells us that something is affecting the horse's normal mobility or function. The changes we actually see are the signs of that underlying problem.

There are many possible causes, ranging from relatively minor foot problems to injuries or conditions requiring urgent veterinary attention.

The important question is therefore not simply “Is this horse lame?” but:

“What is causing this horse to move differently?”

What do we mean by lameness?

Lameness covers a much wider range of movement changes than many owners realise.

A horse may show:

• obvious unevenness between limbs
• reluctance to bear weight normally on one limb
• stiffness when first moving
• altered rhythm or timing of the stride
• difficulty turning in one direction
• reluctance to move forwards
• reduced willingness to work
• difficulty with transitions
• problems on one rein or circle
• reduced performance
• altered posture or weight distribution
• difficulty backing up
• reluctance to pick up a particular foot
• changes in behaviour when ridden, handled or groomed

Some horses with significant discomfort may therefore show no dramatic movement abnormality at all.

Small changes can matter.

Knowing what is normal for your own horse makes it much easier to recognise when something has changed.

Is the horse really taking a shorter stride?

Owners frequently describe a lame horse as moving with a shortened or choppy stride.

What we see, however, can be misleading.

When one limb or part of the body is uncomfortable, the horse may alter when and for how long it loads that limb, transferring weight away from the uncomfortable area more quickly.

That change in timing can make the movement appear shorter, quicker or more hurried.

The important alteration may therefore be the timing and duration of weight-bearing, rather than simply the distance travelled by the limb.

This is one reason why assessment of lameness involves looking at the whole pattern, symmetry and rhythm of movement rather than concentrating on apparent stride length alone.

What can cause lameness?

Almost any structure involved in movement can potentially be responsible.

Problems may involve the:

• hoof
• joints
• bones
• tendons
• ligaments
• muscles
• back
• pelvis
• nervous system

Examples include hoof abscesses, bruised soles, laminitis, arthritis, tendon and ligament injuries, fractures, hoof imbalance and problems affecting the back or other parts of the musculoskeletal system.

Sometimes more than one problem is present.

This can be particularly important in horses with longstanding mobility problems. When a horse protects one uncomfortable area, it may alter the way it distributes weight and moves, potentially placing additional stresses elsewhere.

Where is the problem?

Finding the source of lameness is not always straightforward.

The part of the horse that appears to be moving differently is not necessarily where the original problem lies.

Compensatory movement can sometimes make the picture more complicated, particularly when a problem has been present for some time.

Veterinary lameness assessment may include observing the horse:

• standing
• walking and trotting in a straight line
• turning
• moving on a circle
• moving on different surfaces
• backing up

Depending upon the circumstances, further investigation may include examination of the feet and limbs, flexion tests, diagnostic nerve or joint blocks and diagnostic imaging such as radiography or ultrasound.

The objective is not simply to establish that the horse's movement is abnormal.

It is to determine where the problem originates and what is causing it.

Signs owners may notice

Changes can range from dramatic to extremely subtle.

Look for:

• uneven or asymmetrical movement
• changes in the rhythm of the footfalls
• altered head movement associated with loading a forelimb
• changes in pelvic movement behind
• reluctance to turn tightly
• stiffness after rest
• movement that changes on hard or soft ground
• reluctance to work on one rein
• difficulty maintaining a gait
• reluctance to canter
• changes in canter lead
• reduced impulsion
• altered posture
• repeatedly resting one limb
• heat or swelling
• an increased digital pulse in a foot
• changes in hoof wear
• unexplained deterioration in performance

A change does not have to be dramatic to be significant.

Persistent or repeatedly occurring changes deserve attention.

Sudden severe lameness

A horse that suddenly becomes markedly lame should be assessed carefully.

The horse may:

• be very reluctant to move
• protect one limb
• bear substantially less weight through one limb
• repeatedly shift its weight
• show considerable discomfort when turning
• be unwilling or unable to move normally

Possible causes include hoof abscesses and sole bruising, but severe lameness can also result from fractures, serious soft-tissue injuries, joint problems, laminitis and other conditions requiring prompt treatment.

Contact your vet promptly if your horse is severely lame, is reluctant or unable to bear weight normally, has significant swelling, has sustained an injury, or you are concerned about the severity of the problem.

Avoid repeatedly walking or trotting a severely lame horse simply to keep checking its movement.

The hoof is an important place to look

A substantial proportion of equine lameness originates within the foot.

Possible causes include:

• hoof abscesses
• bruised soles
• hoof cracks
• laminitis
• white line disease
• penetrating injuries
• hoof imbalance
• problems involving structures deeper within the foot

Regular farriery or appropriate hoof care is therefore an important part of maintaining soundness.

However, finding something unusual in a hoof does not automatically prove that it is responsible for the horse's movement problem.

The whole horse still needs to be considered.

Lameness and compensation

Horses naturally attempt to reduce loading of an uncomfortable area.

They may alter the timing of movement, redistribute their weight or change the way different parts of the body are used.

These adaptations can change the forces passing through other limbs and structures.

Over time, this can potentially create additional stresses elsewhere.

This is why apparently separate problems involving the feet, limbs, back or muscles can sometimes be interconnected.

It is also why identifying the primary source of the problem is important rather than concentrating only on the most obvious movement change.

Lameness in older horses

Older horses commonly experience changes affecting mobility, particularly where degenerative joint disease such as osteoarthritis is present.

However, a noticeable deterioration in movement should not simply be dismissed as an inevitable consequence of ageing.

Older horses can develop the same acute problems as younger horses, including hoof abscesses, laminitis and injuries.

A change from an individual horse's normal way of moving deserves attention regardless of age.

What can owners do?

One of the most useful things an owner can do is become familiar with how their horse normally moves.

Regularly observe your horse:

• walking towards and away from you
• turning in both directions
• moving freely in the field
• picking up each foot
• standing at rest

Pay attention to changes in willingness to move, behaviour during grooming or tacking up and performance when ridden or exercised.

Good routine management includes:

• appropriate hoof care
• maintaining a suitable bodyweight
• appropriate exercise and conditioning
• suitable footing
• avoiding sudden increases in workload
• allowing adequate recovery after strenuous exercise
• investigating persistent changes rather than simply continuing to work through them

If you notice something unusual, a short video of the horse moving can sometimes provide a useful record for comparison and may also be helpful when discussing the problem with your vet.

Supporting mobility through nutrition

Nutrition cannot diagnose or correct the underlying cause of lameness, and supplementation should never delay appropriate veterinary investigation.

However, where reduced mobility is associated with joint stiffness, age-related joint change or ongoing musculoskeletal wear, nutritional support may form part of the horse's wider management programme.

FreeStep Joint & Mobility Support

FreeStep Joint & Mobility Support is designed to provide nutritional support for horses where maintaining joint comfort, mobility and freedom of movement is a priority.

It may be particularly relevant for:

• older horses
• horses experiencing joint stiffness
• horses with increased joint wear associated with work
• horses returning to appropriate exercise following veterinary advice
• horses requiring ongoing nutritional support for joint and mobility health

Important: A mobility supplement should not be used as an alternative to investigating unexplained changes in movement. New, persistent or worsening lameness should be assessed so that the underlying cause can be identified.

When should I call my vet?

Seek veterinary advice promptly if:

• the horse suddenly develops severe lameness
• it is unwilling or unable to bear weight normally
• there is significant heat or swelling
• there is a wound or suspected penetrating injury
• you suspect laminitis
• the problem follows a fall, kick or other trauma
• the horse becomes progressively worse
• the problem repeatedly returns
• a mild movement abnormality persists
• there is an unexplained deterioration in performance

Veterinary assessment can also be valuable where the signs are subtle.

Early investigation may identify a problem before it progresses or before compensatory changes develop elsewhere.

The key message

Lameness does not have to be dramatic or immediately obvious.

It is a broad term describing an alteration in normal movement or function resulting from an underlying problem.

What the owner actually sees may be:

unevenness • stiffness • altered rhythm • altered weight-bearing • reluctance to turn • changed behaviour • reduced performance

These are the signs telling us that something may be affecting the horse's normal movement.

The important question is:

What is causing this horse to move differently?

Finding that cause is the foundation of appropriate treatment and management.

“Lameness isn't always obvious”

Purpose: Immediately explain the broader meaning of lameness without associating it only with a dramatic gait abnormality.

Visual concept: A horse moving at trot, with several possible manifestations of lameness positioned around it.

LAMENESS CAN LOOK LIKE:

Uneven movement
Altered rhythm
Stiffness
Reluctance to turn
Altered weight-bearing
Reduced performance

Graphic 2 — “Where can lameness come from?”

Purpose: Show why lameness is an all-encompassing term rather than a single condition.

Visual concept: Side-on anatomical horse illustration or silhouette with areas identified:

Hoof • Bone • Joint • Tendon • Ligament • Muscle • Back • Pelvis

Headline:

LAMENESS DESCRIBES A CHANGE IN MOVEMENT — NOT THE CAUSE

Supporting text:

Problems affecting many different structures can alter the way a horse moves. Identifying the source is essential to appropriate treatment and management.

Graphic 3 — “Why can the stride look shorter?”

Purpose: Explain an important and commonly misunderstood observation about lameness.

Visual concept: A simple sequence showing a horse trotting, concentrating on the timing of weight-bearing rather than portraying one limb as physically taking a dramatically shorter step.

Headline:

IT MAY LOOK LIKE A SHORTER STRIDE — BUT TIMING MATTERS

Supporting explanation:

When a limb is uncomfortable, the horse may reduce the time spent loading it and transfer weight away more quickly.

This altered timing can make the movement appear shorter, quicker or more hurried.

Key message:

LOOK AT RHYTHM, SYMMETRY AND WEIGHT-BEARING — NOT STRIDE LENGTH ALONE.

Bottom safety message:

Sudden severe lameness or reluctance to bear weight normally requires prompt veterinary attention.
