Shockwave Therapy: What It Is, What It Treats, and Whether It's Right for You

At Elite Performance Clinic in Sherman Oaks, we offer clinical-grade extracorporeal shockwave therapy (ESWT) as part of our integrated physical therapy programs. We use it strategically — not as a gimmick or an upsell, but as a targeted tool for specific conditions where the evidence supports its use. This article gives you a complete, honest picture: the science, the conditions it treats, what sessions actually feel like, and when it's worth pursuing.

What Is Shockwave Therapy?

Extracorporeal shockwave therapy uses high-energy acoustic pressure waves — delivered through the skin without any incisions — to stimulate the body's healing response in targeted musculoskeletal tissue. The term "extracorporeal" simply means outside the body: the shockwaves are generated by a device that is applied to the skin surface above the treatment area.

The technology was originally developed from lithotripsy — the non-invasive procedure used since the 1980s to break apart kidney stones using acoustic pressure. Researchers discovered that shockwaves applied to musculoskeletal tissue produced a cascade of biological effects that accelerated healing, particularly in conditions where normal healing had stalled.

The mechanism is multifaceted. When acoustic shockwaves penetrate soft tissue, they create a series of physiological effects: they break up calcifications and abnormal scar tissue deposits, trigger the release of growth factors that stimulate tissue repair, enhance local blood circulation (particularly valuable in tendons, which have poor natural blood supply), promote collagen synthesis, and down-regulate pain signals through a process called hyperstimulation analgesia. The net result is accelerated healing in tissue that has been stuck in a chronic, non-healing state.

This is not a placebo effect. ESWT is approved by the FDA for specific musculoskeletal conditions, and it has been studied extensively in high-quality randomized controlled trials. The evidence base is strongest for tendinopathy and plantar fasciitis, though research continues to expand into additional applications.

Conditions Shockwave Therapy Treats

Plantar Fasciitis and Chronic Heel Pain

Plantar fasciitis — pain along the bottom of the heel and arch caused by inflammation and micro-tearing of the plantar fascia — is one of the most common musculoskeletal complaints in the United States. For most people, it resolves with conservative treatment (stretching, orthotics, targeted exercise) within 6–12 months. But for a significant subset of patients, it becomes chronic and fails to respond to standard intervention.

Shockwave therapy has the most robust evidence base of any non-surgical treatment for chronic plantar fasciitis. Multiple randomized controlled trials and systematic reviews support its effectiveness. At EPC, we typically see meaningful improvement in chronic heel pain patients within 3–5 sessions, often after years of failed conservative treatment.

Achilles Tendinopathy

The Achilles tendon is the thickest and strongest tendon in the body — and one of the most commonly injured in runners, court sport athletes, and active adults over 30. Achilles tendinopathy produces pain, stiffness, and reduced function at the tendon, typically brought on by training load increases or biomechanical stress.

Chronic Achilles tendinopathy is notoriously slow to respond to treatment. The tendon has limited blood supply, which means healing is inherently slower than in muscle or ligament. Shockwave therapy directly addresses this limitation by stimulating local vascularization (new blood vessel formation) and promoting collagen remodeling in the degenerative tendon tissue. When combined with an eccentric loading program — which is the gold standard exercise approach for Achilles tendinopathy — ESWT significantly accelerates the recovery timeline.

Patellar Tendinopathy (Jumper's Knee)

Patellar tendinopathy is extremely common in athletes who perform high volumes of jumping, sprinting, or rapid deceleration — basketball players, volleyball players, soccer players, and track athletes. It presents as pain at the base of the kneecap, typically worsening with activity and gradually interfering with training and competition.

Like Achilles tendinopathy, patellar tendinopathy involves degeneration of tendon tissue without classic inflammation — which is why anti-inflammatory treatments often fail. ESWT targets the degenerative tissue directly, stimulating repair at the cellular level. The evidence supporting ESWT for patellar tendinopathy is strong, and it is now recommended in multiple international sports medicine guidelines for chronic cases that have not responded to exercise therapy alone.

Rotator Cuff Tendinopathy and Calcific Tendinitis

Shoulder pain from rotator cuff tendinopathy is one of the most common complaints we see at EPC in Los Angeles's active population. ESWT is particularly effective for a specific subtype: calcific tendinitis, where calcium deposits have formed within the rotator cuff tendons. Shockwave therapy can fragment and dissolve these calcifications, dramatically reducing pain and restoring shoulder function. Multiple studies have shown resolution of calcification on imaging following ESWT treatment, with corresponding improvements in pain and function.

For non-calcific rotator cuff tendinopathy, the evidence for ESWT is moderate but growing. It works best as part of a comprehensive physical therapy program that includes manual therapy, targeted strengthening, and movement correction.

Lateral Epicondylitis (Tennis Elbow)

Tennis elbow — despite its name, more common in people who have never played tennis — is a tendinopathy of the common extensor tendon at the outer elbow. It causes significant pain and grip weakness, and it is notoriously resistant to treatment. Cortisone injections provide short-term relief but are associated with worse long-term outcomes. ESWT, when applied to the degenerated tendon tissue, has shown consistent evidence of sustained improvement in pain and function, making it one of the most evidence-based treatments for chronic lateral epicondylitis.

Hip Tendinopathy and Greater Trochanteric Pain Syndrome

Lateral hip pain — often diagnosed as greater trochanteric pain syndrome or gluteal tendinopathy — is extremely common in runners and women over 40. It is frequently misdiagnosed as hip bursitis (the bursa is rarely the primary pain generator; the gluteal tendons are). ESWT, combined with gluteal strengthening and load management, is a highly effective treatment for this condition.

Stress Fractures and Delayed Bone Healing

ESWT has applications beyond soft tissue. For stress fractures that are not healing appropriately — or for delayed union after fractures — shockwave therapy can stimulate bone healing by creating controlled micro-trauma that activates the bone's natural repair process. This is one of the more specialized applications of the technology, and one we approach selectively based on clinical indication.

What to Expect During a Shockwave Therapy Session at EPC

Before we apply shockwave therapy, we conduct a thorough assessment to confirm it is the appropriate intervention for your specific condition. ESWT is not appropriate for all patients or all conditions. Contraindications include active infection, bleeding disorders, pregnancy, pacemakers, and certain tumor diagnoses. If shockwave therapy is appropriate for your case, we explain exactly what to expect before we begin.

Sessions typically last 15–20 minutes for the ESWT component, though your total appointment time at EPC includes the full clinical context — assessment, manual therapy or adjunct treatment, and planning for your home exercise program.

The device is applied directly to the skin over the treatment area, using gel to improve acoustic transmission (similar to ultrasound). You will hear the pulses and feel a rhythmic pressure. The sensation is often described as a deep tapping or jackhammer-like pulse — uncomfortable but manageable. Areas with less tissue coverage (near bone or over bony prominences) tend to be more sensitive than meatier areas.

Most people experience temporary soreness in the treatment area for 24–48 hours after a session. This is normal and expected — it reflects the inflammatory response the therapy is designed to trigger. We provide specific guidance on activity modification and icing during this window.

A standard course of treatment is typically 3–6 sessions, spaced one week apart. Most patients begin to experience meaningful improvement within the first 2–3 sessions, though maximum benefit often develops over 6–12 weeks as the tissue continues to remodel.

How Shockwave Therapy Fits Into a Complete Treatment Plan

One thing we want to be direct about: shockwave therapy is not a stand-alone cure. It is a powerful tool that works best when it is part of a comprehensive physical therapy program that addresses the underlying cause of your tendon problem.

Tendinopathy doesn't develop in isolation. It develops because of something — overtraining, biomechanical asymmetry, poor loading mechanics, inadequate recovery, training program errors. If the shockwave therapy accelerates tissue healing but the underlying cause is never addressed, the tendinopathy will return. Every patient at EPC who receives ESWT also receives a tailored physical therapy program that addresses load management, movement quality, and the structural factors driving their condition.

This is the difference between a clinic that offers shockwave therapy as a service and a clinic that integrates it intelligently into a clinical plan. At Elite Performance Clinic, we are the latter.

Is Shockwave Therapy Covered by Insurance?

Insurance coverage for ESWT varies by plan and carrier. Some plans cover it for specific FDA-approved indications (particularly plantar fasciitis). Others do not. Our team will help you navigate the insurance process and clarify what is covered before we begin treatment. For patients without coverage, the cost is approximately $150–$300 per session depending on the number of areas treated — significantly less than surgical alternatives, and with a much shorter recovery.

Who Is a Good Candidate for Shockwave Therapy?

You are likely a good candidate if:

• You have been dealing with a tendon injury or plantar fasciitis for more than 3 months without resolution
• You have tried rest, stretching, and standard physical therapy with limited success
• You have received cortisone injections that provided only temporary relief
• You want to avoid surgery or explore all non-surgical options first
• You are an active individual who cannot afford extended downtime from your sport or training

You are not a good candidate if:

• The injury is acute (less than 6–8 weeks old) — in most cases, standard physical therapy is the appropriate first intervention
• You have a confirmed tendon rupture (ESWT is contraindicated with complete rupture)
• You are pregnant or have a pacemaker
• There is active infection in the treatment area

The Bottom Line

Shockwave therapy is not a magic wand. It is a clinically validated, FDA-approved tool for specific musculoskeletal conditions — particularly chronic tendinopathy — that has transformed outcomes for patients who previously had few non-surgical options. At Elite Performance Clinic in Sherman Oaks, it is one of several advanced tools we use to get athletes and active individuals back to full function.

If you've been living with heel pain, a stubborn tendon injury, or chronic shoulder or elbow pain that hasn't responded to standard treatment, it's worth finding out whether shockwave therapy is appropriate for your case. The consultation starts with a conversation.
