Muscle Strain & Sprain
This page is for educational purposes only and is not a substitute for veterinary diagnosis or emergency care. Always consult your primary veterinarian or a rehabilitation veterinarian before starting treatment. If your pet cannot walk, has sudden paralysis, severe pain, or breathing difficulty, seek urgent veterinary attention.
What is Muscle Strain & Sprain?
Also known as: pulled muscle; ligament sprain; soft-tissue injury; musculotendinous strain.
A strain is damage within a muscle or its tendon from overstretch or overload; a sprain is injury to a ligament that stabilises a joint. Grades range from microscopic fibre damage to partial or complete tears. Pets show lameness, local pain, swelling, and reduced performance. Cats may simply stop jumping to preferred heights.
Accurate diagnosis matters because “sprain” of the stifle may actually be cruciate rupture, and some “strains” hide fractures or nerve injury. Your veterinarian examines the joint for instability and may recommend imaging.
Rehabilitation follows tissue-healing biology: protect, then progressively load. Early uncontrolled exercise can convert a mild injury into a chronic problem; excessive rest without staged loading can leave weakness and re-injury risk.
Common signs to watch for
Signs vary by severity and by whether your pet is a dog or cat. Owners of dogs and cats often notice:
- Sudden or delayed-onset lameness after play, sport, or a slip
- Local swelling, heat, or bruise over a muscle or joint
- Pain on palpation or when the joint is moved through range
- Stiffness after rest; shortened stride
- Reluctance to jump, climb, or turn tightly
- In cats: hiding, reduced grooming of a region, or missing high perches
Causes & contributing factors
- Acute overload: slips, awkward landings, rough play, or collisions
- Repetitive microtrauma from training spikes or fatigue
- Poor footing (wet tiles, uneven ground)
- Muscle fatigue and inadequate conditioning relative to demand
- Secondary strain while compensating for another painful limb or spinal problem
How veterinary rehabilitation helps
Plans match healing phase: protection and swelling control early; mobility and isometric work next; then concentric/eccentric strengthening and sport-specific drills.
Manual therapy, therapeutic exercise, and selected modalities support comfort and tissue quality. Hydrotherapy provides graded resistance with less impact when appropriate.
Owners receive clear activity guidelines — what is allowed on-lead, off-lead, and in the home — so recovery is consistent between clinic visits.
Rehabilitation plans at RehabVet are individualised after a veterinary assessment. We coordinate with your primary vet when imaging, medication, or surgery is part of the overall plan.
Modalities & services commonly used at RehabVet
Depending on your pet’s examination findings, comfort, and goals, a plan may include one or more of the following:
Expected rehabilitation goals
Goals are set for the individual patient. Typical aims may include (not guarantees — outcomes vary):
- Resolve pain and inflammation associated with the injured tissue
- Restore range of motion without joint instability
- Rebuild strength, endurance, and proprioception
- Return to normal or sporting activity with reduced re-injury risk
- Identify and address biomechanical contributors
We do not publish invented success percentages. Progress is tracked clinically (gait, strength, range of motion, pain behaviours, and home function) and plans are adjusted over time.
When to seek veterinary care
- Non-weight-bearing lameness or obvious joint deformity — urgent vet care
- Lameness lasting more than 48–72 hours
- Rapid swelling, heat, or suspected joint instability
- Repeated strains in the same region — deeper orthopaedic work-up needed
- What is the difference between a strain and a sprain?
Strain = muscle or tendon. Sprain = ligament. Both are soft-tissue injuries but involve different structures and can have different instability risks. Veterinary exam clarifies which tissue is involved.
- Is cage rest enough?
Short-term relative rest can help acutely, but prolonged immobilisation without a progressive plan often leaves weakness. Guided rehab balances protection with timely loading.
- Can I use human pain creams on my pet?
No. Many topical and oral human analgesics are toxic to pets. Use only veterinary-prescribed medications and vet-approved topical products.
