What Is Shockwave Therapy?

The Short Answer

Shockwave therapy is a non-invasive treatment that uses a handheld applicator to deliver acoustic pressure waves through the skin to a specific area of the body — most commonly a tendon or region of chronic soft-tissue pain. It does not involve needles, incisions, or medication as part of the treatment itself. It has been studied in randomized clinical trials for a range of musculoskeletal conditions, including plantar fasciitis, Achilles tendinopathy, patellar tendinopathy, lateral epicondylitis (tennis elbow), calcific tendinitis of the shoulder, and greater trochanteric pain syndrome, among others.

What "Shockwave" Actually Means

The term refers to a rapid, high-pressure acoustic pulse — not electricity, and not the kind of "shock" implied by the name. Devices generate these pressure waves in different ways (for example, electrohydraulic, electromagnetic, or piezoelectric systems) and can deliver them as focused waves (concentrated at a specific depth) or radial waves (dispersing outward from the applicator). These differences matter clinically, which is part of why "shockwave therapy" isn't a single, uniform treatment across every device and clinic.

Terminology Patients May Encounter

• ESWT (extracorporeal shockwave therapy): the general clinical/research term.
• Focused shockwave: energy concentrated at a specific tissue depth.
• Radial shockwave (radial pressure wave): energy dispersing from the point of contact, technically a different physical mechanism than focused shockwave, though often grouped under the same umbrella term in casual use.
• SoftWave TRT: the specific technology used at Shockwave Pain Institute — see our dedicated SoftWave TRT page.

What Treatment Feels Like

Most patients describe a firm, rhythmic tapping or pressure sensation. Tenderness during treatment is common directly over the affected area — often the same spot that's already sore day to day. Sessions are brief, and most patients return to normal daily activity the same day, per their provider's guidance.

How Long Sessions Generally Take

Session length depends on the area being treated and the specific protocol used. Your provider will give you a time estimate based on your evaluation.

Commonly Studied Musculoskeletal Applications

Research has evaluated shockwave therapy for conditions including plantar fasciitis, Achilles tendinopathy, patellar tendinopathy, lateral and medial epicondylitis, rotator cuff-related shoulder pain (including calcific tendinitis), and greater trochanteric pain syndrome / gluteal tendinopathy. Evidence quality and effect size differ by condition — see each condition page's "What Research Says" section, and our full Research Center, for specifics.

Biological Mechanisms Researchers Study

Researchers have studied several mechanical and biological responses associated with shockwave exposure in tendon and soft tissue, including effects on local blood flow, pain signaling, and cell activity relevant to tissue remodeling. This is an active area of research. We describe this carefully because a lot of marketing language in this space overstates what's actually been demonstrated — see our note on "regenerative" terminology in the callout below.

Safety and Possible Side Effects

Reported side effects in clinical research are generally mild and temporary, most commonly soreness, redness, or minor bruising/swelling at the treatment site. Serious adverse events are uncommon in the published literature for musculoskeletal applications. Your provider will review contraindications specific to you during your evaluation.

Contraindications

• Pregnancy (in the treatment area), unless specifically cleared by your provider
• Active infection, open wounds, or certain bone conditions at the treatment site
• Certain bleeding disorders or blood-thinning medications, per your provider's screening
• Treatment directly over a pacemaker or certain implanted devices, per your provider's screening
• Suspected tumor at the treatment site

This list is educational and not exhaustive — your provider will conduct a full screening before any treatment.

What Evidence Says — and What It Doesn't Prove

Multiple systematic reviews and randomized controlled trials support meaningful pain and function improvements for several of the conditions above, particularly plantar fasciopathy, lateral epicondylitis, and greater trochanteric pain syndrome. Evidence for some other conditions and for medial epicondylitis specifically is less extensive. Shockwave therapy is not proven to cure every musculoskeletal condition, is not a guaranteed substitute for surgery, and outcomes vary between individuals. We try to represent this honestly rather than overstate it — see our Research Center for the specific studies behind these statements.

Difference Between Treatment and Diagnosis

Shockwave therapy treats a location and a tissue-level problem (such as a tendon), not a self-reported symptom. That's why a medical evaluation — not a quiz or a keyword search — comes first: the correct diagnosis determines whether shockwave therapy is even a reasonable option in the first place.

Why Individual Treatment Plans Differ

Chronicity, severity, prior treatment history, activity goals, and the specific tissue involved all affect how a provider approaches your care. That's why we don't publish a single generic treatment plan — yours will be based on your evaluation.
