Both Radial (EPAT) and Focused (ESWT) Shockwave therapies are non-invasive treatments using high-energy sound waves to stimulate healing in the musculoskeletal system. While they share a common goal of accelerating tissue repair and reducing pain, the way they deliver acoustic energy differs significantly, and understanding these differences can help you and your provider choose the right approach for your condition.
How Focused Shockwave (ESWT) Works
Focused shockwave therapy uses an electromagnetic or piezoelectric generator to produce a single, concentrated acoustic wave that converges at a precise point deep within the tissue. This focused energy reaches depths of up to 12 centimeters, making it ideal for treating deep-seated conditions like calcific shoulder tendinopathy, chronic plantar fasciitis, and non-union bone fractures. The precision of focused shockwave allows clinicians to target specific anatomical structures without affecting surrounding tissue, delivering intense mechanical stimulation exactly where it is needed most.
How Radial Shockwave (EPAT) Works
Radial shockwave therapy, also known as Extracorporeal Pulse Activation Technology (EPAT), generates pressure waves using a pneumatic mechanism that fires a projectile against an applicator. The resulting acoustic waves spread outward from the point of contact, covering a broader treatment area but with less depth penetration, typically reaching 3 to 4 centimeters into tissue. This makes radial shockwave especially effective for conditions affecting larger surface areas such as myofascial trigger points, muscle tightness, and superficial tendon injuries.
Key Differences at a Glance
The primary differences between the two technologies come down to depth, precision, and treatment application. Focused ESWT penetrates deeper and targets a specific focal point, making it the preferred choice for chronic, deep tissue conditions that have not responded to other treatments. Radial EPAT covers a wider area and is generally less intense per pulse, making it well-suited for treating broader muscle and tendon issues, warm-up protocols, and conditions closer to the skin surface.
In terms of treatment experience, focused shockwave sessions tend to involve fewer pulses at higher energy levels, while radial treatments typically use more pulses at lower individual energy settings. Both are performed in-office, require no anesthesia, and allow patients to return to their daily activities immediately after treatment.
Which Conditions Respond Best to Each Type?
Focused shockwave (ESWT) is the treatment of choice for calcific tendinopathy of the shoulder, chronic plantar fasciitis with heel spurs, Achilles tendinopathy, and delayed bone healing. Research published in the Journal of Orthopaedic Research has shown focused ESWT achieves success rates above 75% for many chronic tendon conditions.
Radial shockwave (EPAT) excels in treating lateral epicondylitis (tennis elbow), patellar tendinopathy (jumper’s knee), iliotibial band syndrome, and greater trochanteric pain syndrome. It is also commonly used for myofascial pain and trigger point therapy, particularly in athletes requiring faster muscle recovery.
Why CityIR Offers Both Technologies
At City Integrative Rehabilitation, we are one of the few clinics in New York City that offers both focused and radial shockwave therapy. This gives our specialists the ability to select or combine the optimal technology based on your specific diagnosis, tissue depth, and treatment goals. Many patients benefit from a combined protocol, where focused shockwave addresses the deep pathology while radial shockwave treats the surrounding musculature.
The choice between focused and radial shockwave therapy should always be made by an experienced clinician who understands the biomechanics of your condition. Our team evaluates each patient individually, considering factors such as the location and severity of the injury, chronicity of symptoms, and your overall treatment plan.
