Shockwave Therapy is a non-invasive treatment that can speed the healing of many types of
orthopedic and soft tissue injuries and conditions.  It has been used in Europe in human medicine
to treat tennis elbow, plantar fascitis (heel pain), rotator cuff injuries, calcifying tendonitis of the
shoulder, femoral head necrosis (hip degeneration), non-union fractures, wounds, burns,
osteomyelitis (infection of the bone) with draining tracts, and myofascial pain to name a few.  New
research has shown potential applications in treating periodontal disease, infected wounds, and
to help speed fracture healing and reduce the incidence of non-union fractures.  It has been
approved by the U.S. Food and Drug Administration for use in people to treat plantar fascitis and
tennis elbow that fail to respond to six months of conventional therapy.


Shockwave therapy has been used in the U.S. in veterinary medicine for approximately 7 years.

It has been used successfully to treat animals with both acute and chronic soft tissue unjuries,
bone and joint disease, and back pain.

What is a Shockwave?
A shockwave is a pressure wave – any action that displaces its surrounding medium is a
shockwave.  The ripple created when a stone is thrown into a pond is a shockwave.  The
shockwaves used in equine medicine are generated in a fluid medium inside a transducer head
and are then transmitted readily through skin, fat, and muscle.  The high energy waves are
focused within the transducer head so that the shockwave can be directed to the precise area of
the injury.  When the shockwave hits an area of higher acoustic impedance, such as bone, the
waves slow dramatically and a large amount of energy is released into the surrounding tissue.
What does a Shockwave do?
Shockwave therapy has been shown to:
Stimulate new bone growth
Increase cell permeability and stimulate production of a number of bioactive substances that
contribute to varying metabolic processes
Possibly stimulate fibroblasts, the cells that generate new connective tissue
Cause neovascularization (ingrowth of new blood vessels)

What Can Shockwaves treat in horses ?    
Shockwave therapy has been successfully used to treat many soft tissue and bony problems,
both acute and chronic.  These include, but are not limited to:            
Suspensory ligament tears and strains
Suspensory injuries with avulsion fractures
Tendon tears and strains
Osteoarthritis                                     
Collateral ligament injuries
Navicular syndrome
Ringbone
Joint inflammation and pain
Back pain
Neck pain
Muscle tears and strains
What is the treatment protocol?
The precise treatment protocol depends on the diagnosis of each individual patient.  Treatment
varies in the number of shockwaves administered and the energy of those
shockwaves.
 Most conditions are treated a total of three times spaced at 2-3 week intervals.  
The treatments are easily performed at your facility with the horse under mild sedation.
When will results be seen?
Typically, the horse will start to see some reduction in pain and/or swelling within hours.  This will
generally last 2-4 days and then the horse will return to close to the original status.  Then, over
the next two to three weeks, actual healing will take place.
Does Shockwave work on every case?
No, there is no treatment that is successful in every case.  Shockwave therapy is one of the
most exciting therapies to become available to equine medicine in quite some time
.  It is
extremely important to have an accurate diagnosis and a clearly defined area of injury in order to
direct the shockwaves to the appropriate area.  
A thorough physical exam conducted by a
qualified Veterinarian
, along with diagnostic nerve blocks are important to the diagnostic
evaluation.  Radiographs, diagnostic ultrasound, nuclear scintigraphy (bone scan), and MRI are
all helpful in establishing the nature and location of the injury as well as following the healing
process.
Are All Shockwave machines equal?
Absolutely not.  There are several machines currently marketed as shockwave machines
that do not generate a true shockwave.
 They generate what is called a ballistic or radial
wave.  The physics of this type of wave are completely different from that of a true shockwave.  A
ballistic or radial wave is created when a projectile is rapidly accelerated by compressed air – it
looks like a small jackhammer.  The problem with this type of wave is that all of the energy is
deposited at the skin, and the energy drops off rapidly as you move away from the skin.  The
result being that unless the injury is at the skin, the injured area is not receiving the necessary
energy to help the healing process.  Additionally, since the wave is not focused with this type of
machine, the entire area around the treatment site is receiving the wave, which can potentially
have harmful effects.

The equipment used at Oakhill Shockwave is a focused, electrohydraulic machine
manufactured by Healthtronics (HMT).  This machine is currently used in 18 University
Veterinary Hospitals and is largely considered to be the state of the art.
 With this
machine the shockwaves are focused so that they can be directed precisely to the particular area
of injury.  Additionally, the energy level and the depth of penetration of the shockwaves can be
varied to suit the injury.             
Why Oakhill Shockwave?
Oakhill Shockwave is owned and operated by Dr. Jenny E. Johnson, V.M.D.  Dr. Johnson works
closely with your regular veterinarian to determine the best therapeutic regime for your horse and
his or her particular condition or injury.  
All treatments are performed by Dr. Jenny Johnson,
never a technician.
You can be assured that your horse is receiving the benefit of having an
experienced equine veterinarian knowledgeable in equine anatomy and physiology treating your
horse.  As well as being a vet, Dr. Johnson is an active, competitive Showjumping rider that truly
understands the physical and mental demands placed on equine athletes.
