What is EPAT Radial Shockwave Therapy for Heel Pain and Other Musculoskelatal Conditions?
Extracorporeal Pulse Activation Treatment, also known as EPAT, is a non-invasive, non-surgical treatment option for treatment of ligament and tendon injuries.
There is also evidence it may be helpful for some types of shin splints, sesamoiditis and other tendon injuries.
“Extracorporeal” means “outside the body”. “Pulse Activation” is a type of shockwave, also known as pressure or sound waves.
These shockwaves are generated from the EPAT device and focused onto the painful heel tissue. The shockwaves trigger the body’s repair mechanisms.
The concept behind shockwave therapy in orthopedic disorders is that the shockwave stimulates and reactivates healing to encourage new blood vessel formation 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.
Why Consider Non-Invasive EPAT Treatment for Heel Pain and other Musculoskelatal Conditions?
EPAT has been shown in a number of studies (see below) to be an effective treatment for heel pain on both the bottom and the back of the heel.
EPAT is completely non-invasive and has no dangerous side effects.

How Long Do the Treatments Take and How Many Will I need?
Treatments take approximately 15 minutes. Generally 3 treatments are necessary at weekly intervals. Patients are evaluated for success at 12 weeks after the first treatment.
What Results Can I Expect?
- In general it takes 10 – 16 weeks to see initial improvement
- Maximum improvement is usually seen at about 12 weeks after the final session
Keep in mind that this isn’t like a steroid injection where rapid results can be seen. What shockwave does is stimulate the bodies healing process, so it takes a number of weeks to see results.
Most of the best studies we have found show about 70% of patients with chronic heel pain due to plantar fasciitis or Achilles tendonitis will find relief with EPAT therapy.
In general we see about one third of patients have excellent results, one third see moderate improvement and about one third see no improvement. And although some patients don’t see improvement we have seen absolutely no complications from the procedure.
How is the Shockwave Treatment Performed?
Coupling gel is applied to your foot in the area requiring treatment. EPAT pressure waves are then released via the applicator while moving it over the treatment area.
Is it Safe?
Yes. There are a tremendous number of clinical studies and tests that have confirmed its effectiveness and safety. In fact, for most patients EPAT has virtually no side effects, risks or complications.
Who should receive EPAT Shockwave?
People with the following conditions can often benefit from shockwave therapy:
- EPAT treatment has been shown to be one of the most effective treatments for plantar fasciitis with the highest level of medical evidence for treating this condition.
- You can learn exactly how EPAT Shockwave fits into an overall plantar fasciitis treatment plan in our Plantar Fasciitis Treatment Guide.
- EPAT is about 70% effective in relieving plantar fasciitis pain and has no side effects or complications.
- EPAT is done in combination with treatments to decrease load on the plantar fascia which might include orthotics, walking boots, activity modification and weight loss.
In years past, surgical intervention for chronic plantar fasciitis was required when these other treatments had failed. Today, EPAT is available as an alternative, non-invasive treatment option.
Achilles Tendonopathy / Tendonitis:
Current studies show that EPAT should be incorporated as an initial treatment along with eccentric exercise and reducing tension on the tendon. Go to our Achilles Tendonitis Treatment Guide for detailed information.
Shockwave has been shown to be effective for Achilles pain in the tendon itself and at the Achilles tendon attachment on the heel bone. In fact there is Level 1 evidence (the highest level of medical evidence) showing:
- For mid-portion Achilles tendonopathy 56% of patients had complete recovery with eccentric exercise alone and 82% of subjects had complete recovery at 4 months with a combination of shockwave therapy and eccentric exercise11. More information on shockwave treatment of mid-portion Achilles tendon pain can be found in this article.
- For insertional Achilles tendonopathy 28% of patients had relief with eccentric exercise alone and 64% with a combination of shockwave therapy and eccentric exercise12. More information on treatment of insertional Achilles tendon pain is found in this article and this article.
Medial Tibial Stress Syndrome (Shin Splints)
Three studies have been done on the use of shockwave therapy for treatment of medial tibial stress syndrome. Two of those were very positive for the use of shockwave therapy in relieving shin splint pain. One of the studies was inconclusive.8-10
A preliminary study has shown very good results for treating sesamoid pain with shockwave therapy. Larger studies are ongoing. Results so far are very promising13.
Peroneal Tendonitis, Posterior Tibial Tendonitis and Capsulitis
There are no studies we have found on using EPAT for other types of tendonitis and ligament inflammation of the foot. The effects, however, should be the same on other tendons and ligaments and the treatment can be done on these areas also as long as the patient understands that we do not have the same quality studies as we do for plantar fasciitis and Achilles tendonitis.
Who should not receive EPAT Shockwave treatment?
Your health history will be reviewed by your doctor to see if this treatment is appropriate for you. EPAT 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 EPAT. Also, children or pregnant women are not considered appropriate candidates for EPAT.
EPAT is usually not needed for patients who have had plantar fasciitis for a very short period of time as those patients usually respond to less expensive treatments.
What are the side effects of EPAT?
EPAT has virtually no serious side effects, especially when compared to surgery and even injections. Also, it has a much shorter recovery time than surgery.
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. EPAT is FDA cleared and is used all over the world.
How Does EPAT Work?
For over thirty years, extracorporeal shockwave lithotripsy (ESWL), a non-invasive procedure, has been successfully used in the treatment of kidney stones. As the force of a shockwave causes the disintegration of the kidney stone, so does the acoustic energy promote healing in the distressed tissue.
Shockwave therapy produces a regenerative and tissue-repairing effect in musculoskeletal tissues,
The shockwave stimulates and reactivates healing through revascularization (creation of new blood vessels), differentiation of stem cells (creating more of the cells that cause tissue to heal) and other elements necessary to advance normal tissue healing.
Insurance Coverage for EPAT
Insurance does not cover the cost of the EPAT procedure.
If you have a Flexible Spending Account (FSA) through your employer, you can usually use FSA funds to pay for the EPAT procedure. This can be confirmed with your plan administrator.
How Much Does EPAT Cost?
EPAT costs $140 per session.
- Most studies recommend a series of three sessions over a 3 – 4 week period for plantar fasciitis ($420 total)
- Achilles tendonitis can be more resistant to treatment and 4 sessions are recommended. ($560)
According to most studies, EPAT is successful about 70% of the time. Payment is due prior to the procedure being performed.
Is EPAT safe for pregnant patients?
EPAT is a safe treatment, but has never been tested on pregnant patients. We advise that you wait at least 3 months post partum before treatment, as many foot pains subside after weight loss and hormonal equilibrium is reached.
