Shockwave therapy for plantar fasciitis: radial, focused, and who should skip it

The heel this page is about

Plantar fasciitis is irritation and degeneration where the plantar fascia anchors into the heel bone. The fascia is a thick band under the foot. It starts at the medial calcaneal tubercle, the bump on the inside of the heel, and runs forward toward the toes. It supports the arch the way a bowstring supports a bow. When that anchor has been overloaded for months, the first steps after sleep or a long sit are often the worst. The pain can ease as tissue warms up, then come back after a shift on hard floors.

That pattern is so common that people start calling any heel pain plantar fasciitis. It is not. A stress fracture, nerve entrapment under the heel, a ruptured fascia, inflammatory arthritis, and an infected or diabetic wound can all hurt in the same neighborhood. MedlinePlus groups these under heel injuries and disorders for a reason: the name on the search box is not the diagnosis. The examination is.

The American Academy of Orthopaedic Surgeons is blunt about bone spurs. A spur can show up on an X-ray after years of tension at the fascia insertion. Most people who have a spur do not have heel pain, and the pain of plantar fasciitis can be treated without removing the spur. If someone has told you the spur is the thing that must be cut out, that is a different conversation from the one this page is having. Imaging still matters. It is how a fracture or significant arthritis gets ruled out. It is not an automatic ticket to the operating room.

Why shockwave shows up after the simple things

Rest, a better shoe, a gel heel, calf and plantar stretches, tape, and a short course of anti-inflammatory medicine settle a lot of new heel pain. Physical therapy builds capacity so the fascia can take load again. Those are reasonable first moves, and this office will usually ask what you have already done before anyone talks about a machine.

Shockwave, or extracorporeal shock wave therapy, is a different tool. A handpiece on the skin delivers acoustic pressure waves into the sore tissue. There is no incision and, in the modern low-energy protocols, no anesthetic. The idea is to provoke a healing response in tissue that has become a chronic, under-repaired problem rather than a fresh sprain. It is considered when the simple care has already had a fair chance.

What the better trials actually measured

Two studies are worth knowing because they were large, sham-controlled, and aimed at chronic plantar fasciitis.

Gerdesmeyer and colleagues, published in the American Journal of Sports Medicine in 2008, tested radial shockwave. Two hundred forty-five people received three sessions at 0.16 millijoules per square millimeter and 2,000 impulses, or a sham. At 12 weeks the composite heel-pain score had fallen about 72 percent with radial shockwave and about 45 percent with sham. Overall success was 61 percent versus 42 percent. The gap was still there at 12 months. The authors reported no relevant side effects. This was an outpatient treatment without anesthesia.

Gollwitzer and colleagues, in the Journal of Bone and Joint Surgery in 2015, tested focused shockwave in a U.S. Food and Drug Administration trial. About 250 people were randomized to focused shockwave at 0.25 millijoules per square millimeter or to sham, three weekly sessions of 2,000 impulses, again without local anesthesia. At 12 weeks the composite pain score fell about 69 percent with focused treatment and about 35 percent with sham. Success rates landed between 50 and 65 percent. The device-related events they recorded were temporary pain and swelling.

Read those numbers as a range, not a warranty. Sham groups also improved. Some people in the active groups did not. The studies enrolled chronic, stubborn cases, not a heel that has hurt since Tuesday. They do not say shockwave beats surgery, and they do not say it replaces a change in the load that irritated the fascia in the first place. Stretching and gradual return to activity still sit beside it. A later line of research has even found that plantar-fascia-specific stretching plus shockwave can beat shockwave alone. The machine is not the whole plan.

Radial or focused, on this heel

Radial pressure waves enter at the skin and spread through a broader, shallower field. On a heel that often means the fascia as it fans across the inside of the arch, and the muscles just under the skin. Focused shockwave is concentrated at a chosen depth. That is the tool when the painful point is a small, deep insertion or a calcification the exam can actually locate.

Richter Family Chiropractic publishes that both Storz forms are in the building, along with a Storz Magnetolith for extracorporeal magnetotransduction therapy. The point of owning both is that the exam picks the depth. An office with one handpiece has already made that choice before you walk in. A fuller comparison of the two wave types, including sensation and side effects, is on the radial versus focused page. EMTT, which does not touch the skin, is a separate guide.

What a session feels like, in the clinic's own description: gel on the skin, the handpiece against the heel, a firm rapid tapping, sometimes an audible click, you awake and talking. Energy is set from the exam and adjusted while the tissue responds. You are not put to sleep for this.

Who should not be on the table

The practice's shockwave page says treatment is not used during pregnancy, over an active infection or a tumor, or when someone has a blood-clotting disorder. A pacemaker or other implanted electronic device is screened before EMTT, which is often discussed in the same visit. Confirm that list against the current device manual. It is one of the open items at the bottom of this page.

A few other situations belong in a medical office before anyone discusses acoustic waves. You cannot comfortably bear weight after a fall or a misstep. The heel is hot, red, and you have a fever. There is an open wound, especially if you live with diabetes. Pain wakes you from sleep and is not the familiar first-step pattern. You have numbness, or weakness that is new. Those are reasons to be examined for a fracture, infection, nerve problem, or systemic disease, not reasons to start a three-visit series.

What this office will and will not promise

The plantar fasciitis program on the main site pairs the two shockwave devices with Class IV laser, EMTT when it fits, chiropractic care for the joints above the foot, and physiotherapy. Ankle, knee, and hip mechanics change how the fascia is loaded. Treating only the sore centimeter and ignoring a stiff calf or a collapsed midfoot is how heel pain becomes a recurring appointment.

There is no published package price for a shockwave series here. The $59 new-patient exam is the published number. It covers the consultation, the exam, X-rays if they are indicated, and the second visit where the plan and the cost are explained. Treatment is billed only if you agree. Anyone quoting you a heel-pain special before that exam is not describing this office.

A sensible order, if the heel has hurt for months

Start with the things that are cheap and specific: shoes that are not dead, a short-term heel cushion if it helps you walk, and calf plus plantar loading you can actually do. If that has already failed, or the pain is changing how you work, an exam is the next honest step. The exam decides whether the story is plantar fasciitis at all. If it is, and it is chronic, shockwave is one option with real trial data behind it. If it is not, you should leave with a different plan or a referral, not a series you did not need.

Bring old X-rays or an MRI if you have them. Bring the shoes you wear to work. Be ready to say how long the morning pain lasts and what you have already spent money on. That history is more useful than a photo of a spur.
