Extracorporeal Shock Wave Therapy (ESWT)

What is Shockwave Therapy?

Shockwave Therapy is a fast and gently non-invasive, non-surgical method of reducing musculoskeletal pain from plantar fasciitis, tendonitis, and other soft tissue disorders in the foot and ankle. The technology is derived from lithotripsy, a technique used today to disintegrate kidney stones without the use of invasive surgery.  During high-energy radial shock wave therapy with the Zimmer EnPuls 2.0 Pro, a high-intensity mechanical wave is transmitted from a probe through the skin where it interacts with the tissues of the body.

This leads to a cascade of beneficial effects: The shockwave stimulates and reactivates healing to encourage new blood vessel formation, disrupts scar tissue, releases local growth factors and recruits stem cells; all of which accelerates the healing process. Additionally, shockwaves help to over-stimulate pain transmitting nerves, which can lead to a reduction in sensitivity and pain.


Podiatric Indications for Shockwave Therapy:

  • Chronic heel pain
  • Chronic Plantar Fasciitis (Fasciosis)
  • Achilles Tendinosis
  • Chronic Ankle Sprain
  • Mortons neuroma
  • Acute and Chronic muscle pain
  • Tendinosis of the foot and ankle
  • Fractures
  • Recalcitrant Neuroma
  • Chronic wounds

Why Consider Non-Invasive Shockwave Therapy?

This modality has been used with success for over 30 years in Europe and over 15 years in the United States. Shockwave therapy has been shown in numerous studies to be an effective treatment for chronic heel pain on both the bottom and back of the heel.  The success rates (70-85%) are equal to or greater than traditional methods including surgery without the risks, complications, and lengthy recovery periods a surgery may entail. Evidence based medicine also shows efficacy in treatments of other pathologies including muscle pain, tendonitis and neuromas to name a few.

Patients treated with shockwave therapy may bear weight and resume normal activities immediately following treatment with the exception of high impact exercises. Many patients find a significant and immediate reduction in their pain. Some patients will feel results gradually after each treatment.

Benefits of Non-Invasive Shockwave Therapy:

  • 70-85% success in relieving pain of plantar fasciitis and Achilles tendonitis
  • Patients can bear weight immediately
  • Similar results to surgical intervention without having surgery and without the post-operative surgical risks
  • Risks associated with surgery and general anesthesia are eliminated
  • Patients can return to work immediately
  • Most patients return to strenuous activity after 4 weeks
  • Completely non-invasive
  • Reduces potential need for other treatments
  • Fast, safe and effective

How is the treatment performed?

The Zimmer EnPuls 2.0 Pro is a machine with a small applicator that resembles an ultrasound wand. It is administered once a week for a series of 3 to 6 treatments with an average of 3.  Treatment intervals should not exceed one week for optimal results. Each treatment takes approximately 10 minutes depending on the location and number of areas treated.

Your favorite podiatrist at Kalmar Family Podiatry performs all your treatments. The doctor applies the applicator to the foot and administers the ballistic waves by moving over the affected area in a very slow, circular motion. During the treatment there may be some minor discomfort.

Is it safe?

Yes, this technology has been tested and studied for nearly 30 years and have confirmed its safely and efficacy. There are virtually no serious side effects.  Some patients may experience a short period of slight tingling, warmth or numbness immediately following treatment. These potential effects typically resolve within a few days.

Insurance Coverage:

Unfortunately, at this time no insurance company covers the cost of Shockwave Therapy. Some patients may be able to use your Flexible Spending Account (FSA) through your employer. If needed, an individual payment plan can be formulated, but a down payment will be collected during initial treatment visitation.

Here at Kalmar Family Podiatry our protocol is to perform 3 – 6 treatment sessions with each treatment typically 1 week apart. We strongly advocate shockwave therapy while you start or maintain a good physical therapy regimen for your injury. We then see you back in 4 weeks after your last treatment for a follow-up visit to check your progress.
