Shockwave Treatment for Plantar Fasciitis

Plantar Fasciitis

What is Shockwave Treatment for Plantar Fasciitis?

Shockwave treatment, also known as Extracorporeal Shock Wave Therapy (ESWT), is a conservative procedure to treat plantar fasciitis of the foot, where shockwaves are passed through the heel to stimulate healing of the inflamed plantar fascia tissues. Shockwave treatment utilizes mechanical high energy sound waves, which function by improving blood flow to the inflamed area to speed up the healing process.

Shockwave treatment or ESWT is a non-invasive (no cutting of skin and no introduction of any medical device in the body) method of treating soft tissue injuries. Extracorporeal means outside the body. ESWT does not disintegrate tissue; rather it causes biological effects that help in tissue regeneration. ESWT reduces pain and sensitivity immediately by over-stimulating pain transmission nerves and triggers repair mechanisms.

What is Plantar Fasciitis?

Plantar fasciitis is a painful foot condition where the plantar fascia becomes inflamed from overstretching or overuse, causing pain in the heel and bottom of the foot. Repetitive strain to the plantar fascia can result in tiny tears in the ligament, leading to pain and swelling, which can make walking difficult. It is one of the most common causes of heel pain and is most often seen in middle-aged men and women, but may also occur in those who are constantly on their feet or active in sports and athletics.

Anatomy of the Plantar Fascia

The plantar fascia is a long, thin ligament present along the bottom of the foot that creates the arch of the foot. It extends from the heel bone, and then splits and fans out to attach itself to the toes. It acts as a shock absorber and supports the arch of your foot and functions like a bowstring to stiffen your foot while you walk.

Indications for Shockwave Treatment for Plantar Fasciitis

Shockwave treatment is indicated when other conservative treatment methods such as rest, medications, physical therapy, night splints, supportive shoes, and orthotics do not show improvement even when used over a period of 6 months. It is used as an alternative treatment modality to surgery. Most of the patients who undergo shockwave therapy show a significant reduction of pain and improvement in movements compared to other conservative treatment options.

Preparation for Shockwave Treatment for Plantar Fasciitis

Preparation for shockwave treatment for plantar fasciitis will involve the following steps:

  • A review of your medical history to determine if the procedure is appropriate for you.
  • You should inform your doctor of any medications, vitamins, or supplements that you may be taking.
  • Your doctor will advise you to stop taking any anti-inflammatory medications such as aspirin or ibuprofen at least 5 days prior to the procedure.
  • A written consent will be obtained from you after the surgical process has been explained in detail.

Procedure for Shockwave Treatment for Plantar Fasciitis

Shockwave treatment is performed on an outpatient basis and hence you can go home the same day without the need for an overnight stay. You may require at least 2 to 3 sessions of shockwave therapy based on the severity of the condition. The procedure involves the following:

  • You are asked to lie on your stomach with your legs supported by a pillow.
  • Local and/or sedation anesthesia may be administered for comfort as high-energy shock waves are employed.
  • Ultrasound gel is applied to the heel area to enhance transmission of the shockwaves.
  • Shockwaves are then delivered through a hand-held probe attached to the shockwave machine.
  • The probe is moved over the heel area to deliver compressed air pulses in a systematic manner through the gel.
  • The shock waves penetrate the skin of the heel area to stimulate healing.
  • You may feel some discomfort during the process and may feel a tapping sound from the probe.
  • The treatment takes around 10 to 20 minutes per foot.

Post-Procedure Care and Instructions

Post treatment, you will be immediately able to walk and return to your normal activities right away, including return to work. However, your doctor may advise you the following:

  • Rest and elevate the foot for a day or two to promote complete healing.
  • Refrain from any strenuous activities, heavy lifting, or high-impact exercises for at least 2 days.
  • Gentle stretching exercises are advised the following day of the procedure.
  • Refrain from running for at least a week.
  • Refrain from ice therapy or taking any anti-inflammatory medications, such as aspirin for at least 2 days.
  • Over the counter pain medications can be taken for comfort if the pain is noted.
  • Adhere to scheduled follow-up appointments to monitor your progress.

Risks and Complications of Shockwave Treatment

Shockwave therapy is a relatively safe procedure; however, as with any procedure, there are risks and complications that could occur around the heel area, such as:

  • Pain
  • Swelling
  • Skin reddening
  • Bruising
  • Minor bleeding
  • Numbness
  • Minimal risk of Achilles tendon rupture
