NON-INVASIVE TREATMENT FOR HEEL
PAIN
What is ESWT?
Extracorporeal shockwave treatment, also known as ESWT, is a non-invasive,
non-surgical treatment option for the intense, persistent heel pain
associated with chronic plantar fasciitis and achilles tendonitis. "Extracorporeal" means "outside
the body". Shockwaves, also known as pressure or sound waves,
are generated from a special ESWT device and focused onto the targeted
tissue. The shockwaves are delivered outside the body to trigger
an individual's own repair mechanisms. The concept behind shockwave
therapy in orthopedic disorders is that the shockwave stimulates
and reactivates healing to encourage revascularization and other
elements necessary to advance normal tissue healing. Additionally,
shockwaves help to over-stimulate pain transmission nerves, which
can lead to a reduction in sensitivity and pain.
What is plantar fasciitis?
The plantar fascia is a band of connective tissue on the plantar
surface of the heel that plays a large role in maintaining the normal
architecture of one’s foot. Plantar fasciitis is a common clinical
condition caused by overuse or injury of the plantar fascia and is
defined as traction degeneration of the plantar fascial band at its
origin on the medial tubercle of the calcaneus. Inflammation, fibrosis,
and decreased vascularization of the fascia occur, causing symptoms
of heel pain. Other symptoms that may occur include burning in the
sole of the foot, recurring foot pain that is especially aching in
the morning or after sitting, or heel pain after beginning a new
exercise routine.
What causes plantar fasciitis?
There are a number of predisposing factors, including foot pronation,
obesity, poor fitting shoes, minor trauma, occupational risks and
change in exercise program. Although everyone is at risk, plantar
fasciitis is most commonly found in athletes, runners, overweight
individuals, or those who are required to stand on hard surfaces
for prolonged periods of time. Although approximately 2,000,000 Americans
suffer from plantar fasciitis ESWT is an appropriate treatment option
in approximately 5 to 10% of those cases, as the remainder of the
cases can be adequately addressed with more conservative therapies.
Who should receive ESWT for plantar fasciitis?
Prior to undergoing ESWT treatment, the patient must have been diagnosed
with chronic plantar fasciitis for at least six months. Only after
the patient’s symptoms fail to respond to three conservative
treatments should ESWT be administered. Conservative treatments include
rest, physical therapy, heel cushions, non-steroidal anti-inflammatory
drugs (ibuprofen, acetaminophen, etc), cortisone injections, taping,
orthotics, shoe modifications, night splinting and casting. In years
past, surgical intervention for chronic plantar fasciitis was required
when these other treatments had failed. Today, ESWT is available
as an alternative, non-invasive treatment option.
Who should not receive ESWT treatment for plantar fasciitis?
Your health history should be reviewed with your doctor to see if
this treatment is appropriate for you. ESWT is not recommended for
patients with certain conditions. Patients with pacemakers and patients
taking medications that may prolong or interfere with blood clotting
(coumadin) are not candidates for ESWT. Also, children or pregnant
women are not considered appropriate candidates for ESWT. ESWT is
not appropriate for individuals suffering from acute plantar fasciitis.
What are the side effects of ESWT?
Compared to surgery, ESWT has fewer side effects and a much shorter
recovery time. The most common patient complaint is some minor pain
or discomfort during and after treatment. Other side effects might
include minor skin bruising, reddening, or swelling of the treated
area. However, these possible occurrences usually resolve within
a few days. The risks associated with surgery and general anesthesia
are eliminated.
