Does shockwave therapy work, and what are the side effects?

Searching "does shockwave therapy work" mixes a scientific question with a shopping question. The scientific question asks whether an acoustic series changes pain more than a convincing pretend treatment, in a defined condition, over a defined window. The shopping question asks what it feels like, what can go wrong, and what it costs in this building. Those answers are not the same paragraph. A marketing line that says the technology works, full stop, has skipped the condition, the sham arm, and the invoice.

A scoreboard, limited to the trials this guide is allowed to cite

The cleanest sham-controlled numbers in the source list are about chronic plantar heel pain. They are not a universal tendon certificate. They are also not small. Putting them in one grid keeps the percentages from being paraphrased into a slogan.

	Radial trial, Gerdesmeyer 2008	Focused trial, Gollwitzer 2015
Who enrolled	245 people, chronic recalcitrant plantar fasciitis	About 250 people, chronic plantar fasciitis
Comparator	Sham	Sham
Dose that was frozen	0.16 mJ/mm2, 2,000 impulses, three sessions	0.25 mJ/mm2, 2,000 impulses, three weekly sessions, no anesthesia
Composite pain at 12 weeks	Down 72.1% versus 44.7% with sham	Down 69.2% versus 34.5% with sham
Success, as those papers counted it	61% versus 42.2%	50% to 65%
Downside the paper recorded	No relevant side effects	Temporary pain and swelling

The radial paper (opens in a new tab) is a multicenter, placebo-controlled study in the American Journal of Sports Medicine. The focused paper (opens in a new tab) is a randomized multicenter study in the Journal of Bone and Joint Surgery. Both kept people awake. Both used the 12-week comparison as the headline. A gap on a chronic heel is not a coupon for a permanent result in a different joint.

Read the sham column before the active column. Those sham scores are not zeros. People improved while receiving a procedure that was designed not to deliver the real dose. Expectation, time, quitting the aggravating activity, and the simple fact of being examined all move pain scores. The interesting finding is the extra movement in the active arms, not a miracle relative to baseline. Success definitions still left a large minority unimproved. An accurate summary is that active treatment beat sham for many people with long-standing plantar fasciitis. The word works is larger than the data.

The heel guide walks the same studies from the foot's point of view: /shockwave-therapy-for-plantar-fasciitis. The machine comparison, including why 0.16 and 0.25 are not a single dial, is on /radial-vs-focused-shockwave. MedlinePlus on heel injuries and disorders (opens in a new tab) is the reminder that heel pain is a neighborhood, not a diagnosis you confer on yourself from a search box.

What "works" did not mean

The trials did not claim shockwave replaces a change in load. They did not enroll fresh two-week heels as their main story. They did not pit the devices against surgery and declare a victor. They did not test tennis elbow, a mid-portion Achilles, a patellar tendon, or a lumbar disc. MedlinePlus on tendinitis (opens in a new tab) describes tendon pain as its own family of problems, often tied to overload and slow to settle. Shared family traits are not shared trial results. An elbow that hurts with a handshake gets its own page, /shockwave-therapy-for-tennis-elbow, and that page does not inherit these percentages.

Absolute differences matter as much as the relative drama. A composite score that falls about 72 percent from a high baseline can still leave meaningful pain. Success criteria in trials are thresholds the investigators chose. Crossing a threshold is not the same sentence as "I forgot which heel it was." If a clinic quotes only the active-arm percentage and deletes the sham arm, you are being shown a poster, not a paper.

Sensation and the short list of recorded harms

You feel the impulses. That is a feature of the way these studies were built, not a flaw in the chair. Local anesthetic was withheld so the dose stayed inside what a person could report and so the tissue response was not numbed away. The most irritable square centimeter is the one that speaks up. Radial application tends to feel like a spread-out tapping under the cap. Focused application tends to feel more pinned to a point. Either can be briefly sharp. You should be able to answer questions. A setting that makes you unable to talk is a setting to reduce, not a setting to endure for the sake of a protocol someone saw online.

Afterward, the focused trial's named device-related events were temporary pain and swelling. The radial trial's authors did not record relevant side effects. Ordinary clinical counseling also covers a sore day, pink skin, or an occasional small bruise, without a rate this office has published. Rare scary events are not given a number here because inventing one would be worse than silence. Screening is how the avoidable harms get handled before the console is unlocked.

Published shockwave limits at this practice: not while pregnant, not through an infection, not through a tumor, and not when a blood-clotting disorder is part of the history. Confirm that against the current instructions for use. The manual check is an open task, not a completed signature. Pacemaker and defibrillator questions are EMTT screening, a different device. Do not let a shockwave FAQ answer them by accident. Fever with a red joint, inability to bear weight after trauma, and pain that wakes you in a pattern unlike your usual overload story belong to a medical workup. The clinic's shockwave page states the service in the practice's voice. This guide is the evidence commentary beside it.

Why the session price is missing on purpose

There is no honest line on this page that reads "shockwave costs X." The practice has not issued a range, and visit two is where a plan-specific quote is supposed to happen, before treatment starts. Filling the blank with a regional average from someone else's website would launder a guess into a fact.

The fee that is printed is the new-patient exam at $59. It applies to first-time patients and to people who have not been seen here in more than two years. In plain terms, that fee covers a consultation, the examination, X-rays when the findings call for them, and a second visit that explains what was found. Treatment is a separate charge, and only if you decide to proceed. Each of those first visits is about 30 to 35 minutes. What the exam includes is the practice's own description. Broader cost questions, including how a chiropractic visit is priced when no machine is involved, sit on /how-much-does-a-chiropractor-cost.

If you are paying yourself, a written estimate is part of the landscape. The No Surprises Act materials from CMS (opens in a new tab) and the practice's good-faith estimate page describe an estimate at least one business day before the service, and a dispute right if the bill is $400 or more over that estimate. That rule does not set the clinical fee. It sets a paperwork floor for uninsured and self-pay care.

Coverage is a second blank. The office says it works with most PPO and HMO plans and with Medicare, and that coverage varies. Medicare's published chiropractic benefit is narrow: Part B covers manual spinal manipulation by a chiropractor to correct a subluxation, by hands or with a hand-held device. After the deductible the coinsurance is 20 percent. Medicare states that it does not cover other services or tests a chiropractor orders, and it names X-rays, massage, and acupuncture as examples. Shockwave is not manual spinal manipulation. Do not assume the manipulation benefit pays for an acoustic series. Do not assume a private plan does either, until the desk has run the card. Cash, check, card, and HSA or FSA cards are the self-pay routes the office names. CareCredit and Cherry are financing products with their own approval. Attorney liens are for personal-injury cases. None of those sentences is a promise that your series is paid.

How to read a before-and-after claim

A useful claim names the condition, the comparator, the time point, and the people who did not get better. A weak claim shows a device, a percentage with no denominator, and a testimonial this practice is not going to imitate. This guide does not publish success rates of its own. The doctors have not recorded a quote for this page. Dr. Matthew Richter, DC, and Dr. William Choi, DC, are the chiropractors who would have to stand behind any such sentence, and sign-off is still pending.

Use the scoreboard as a ceiling on enthusiasm and a floor on nihilism. Chronic plantar fasciitis is the condition where these two trials give a real, bounded yes for many people. Other tendons are separate decisions. Side effects in the papers were limited and temporary, and the session itself is noticeable. The price is told to you after the exam, not harvested from an ad. If those four sentences are enough to decide you want the exam, that is a reasonable use of the evidence. If you need a guarantee, the evidence does not have one to sell.
