what is shockwave therapy? a complete guide to eswt treatment

Shockwave therapy, or extracorporeal shockwave therapy (ESWT), is a non-invasive treatment that uses high-energy acoustic waves to stimulate healing in damaged tissues and joints. Originally developed in the 1980s for kidney stones, it's now widely used across physiotherapy and orthopaedics to treat chronic pain conditions like plantar fasciitis, tennis elbow, and calcific tendinopathy. At CK Physio in West London, we integrate shockwave therapy with tailored physiotherapy to accelerate recovery and reduce reliance on painkillers and surgery.

What is Shockwave Therapy?

Shockwave therapy is a medical treatment that delivers high-energy acoustic pulses to injured or degenerative tissue, triggering a repair cascade at the cellular level. Unlike ultrasound (which generates heat through friction), shockwaves create mechanical stress that stimulates blood vessel formation and collagen remodelling—a process called mechanotransduction. This reawakens dormant healing mechanisms in chronic conditions where the body has "given up" trying to repair itself.

The term "shockwave" refers to the acoustic energy profile, not the sensation. Shockwaves are pressure pulses generated by a specialised machine and transmitted through your skin via conductive gel. They're not electrical; they're sound waves at therapeutic intensity. The Chartered Society of Physiotherapy (CSP) and NICE recognise ESWT as a legitimate option for selected musculoskeletal conditions, though NICE notes that more UK-based research is needed to fully establish its cost-effectiveness in the NHS.

At CK Physio, we use shockwave therapy alongside manual physiotherapy and electrotherapy to personalise your recovery. Rather than relying on shockwaves alone, we combine them with targeted exercises and hands-on treatment to rebuild strength and movement quality—ensuring the benefits last years, not months.

How Does Shockwave Therapy Work?

Shockwave therapy works through three main mechanisms: mechanical stimulation of tissue, triggering of new blood vessel formation (neovascularisation), and activation of growth factors that promote collagen synthesis. When a shockwave pulse reaches damaged tissue, it creates microruptures and cavitation bubbles (tiny imploding air pockets) that stimulate cells to release healing signals. This is entirely different from injury damage—it's controlled, therapeutic stimulation that restarts a stalled healing cycle.

There are two main types of shockwave delivery: focused and radial (or ballistic). Focused shockwaves concentrate energy at a precise point 5–12 cm deep, ideal for small, well-defined lesions like calcific deposits or tendon tears. Radial shockwaves spread energy across a wider area 3–4 cm deep, better suited to larger muscle groups and trigger point release. Both are effective; the choice depends on your condition, tissue depth, and anatomy.

Research published in PubMed shows that at the cellular level, shockwaves increase expression of angiogenic growth factors—proteins that signal blood vessels to sprout and rebuild. They also reduce inflammatory markers in chronic pain states, which explains why patients often feel pain relief within weeks, even as tissue remodelling continues over months. This is why a course of 3–6 sessions, spaced 1–2 weeks apart, produces cumulative benefit: each session amplifies the healing cascade, and the interval allows tissue to respond and adapt. The International Society for Medical Shockwave Treatment (ISMST) recommends this protocol as the standard of care.

What Conditions Does Shockwave Therapy Treat?

Shockwave therapy has a tiered evidence base. Some conditions are supported by robust clinical trials; others are emerging. We've categorised them to help you understand where the strongest evidence lies and which conditions may benefit from shockwave as part of a broader rehabilitation plan.

Tier 1: Strong Evidence

Plantar Fasciitis: The most studied indication. Clinical success rates range from 75–80% (Royal Orthopaedic Hospital, UK) to 34–88% across studies, depending on patient selection and follow-up duration. Patients typically report 50–70% pain reduction within 4–6 weeks and sustained improvement at 2 years. ESWT is especially valuable for patients who've failed conservative physio or steroid injections.

Calcific Tendinopathy (Shoulder): One of ESWT's greatest successes. Ultrasound-guided focused shockwave therapy achieves success rates of 90.9% (with imaging) and breaks down calcium deposits while triggering tissue repair. Many patients avoid surgery. Results are visible on ultrasound and clinically over 8–12 weeks.

Lateral Epicondylitis (Tennis Elbow): Shockwave therapy addresses the underlying tendon degeneration at the elbow. Success rates of 60–70% are reported, with benefit seen especially in chronic cases resistant to physio and injections. Typically requires 3–5 sessions.

Tier 2: Moderate Evidence

Achilles Tendinopathy: Both insertional and mid-substance tears respond well. Studies show 50–75% improvement in pain and function. Shockwave therapy helps here because the Achilles is a load-bearing tendon; ESWT reintegrates it structurally while physio rebuilds strength.

Greater Trochanteric Pain Syndrome (GTPS / Hip Pain): Pain at the hip from tight or degenerative muscles. Radial shockwave therapy delivers 68.3% pain improvement over 8 weeks. It works especially well for lateral hip pain from running or prolonged sitting—the shockwave dispersal is ideal for the broad gluteal muscle group.

Tier 3: Emerging Evidence / Selected Cases

Myofascial Trigger Points: Radial shockwave therapy is effective for chronic muscle tightness and trigger points that resist manual therapy. Sessions are often combined with needling or massage for synergistic effect.

Non-Union Fractures & Delayed Healing: A 73% healing rate is reported for bone fractures that have plateaued. Shockwave stimulates osteoblast (bone-building cell) activity.

Other Conditions: Knee osteoarthritis, rotator cuff tendinopathy, and patellofemoral pain show promise — Versus Arthritis provides patient-friendly guidance on these emerging applications — but require more high-quality UK research before we can claim the same level of confidence as for plantar fasciitis.

The key principle at CK Physio is that shockwave therapy is most effective when paired with a tailored physiotherapy programme. We assess whether your condition fits the evidence base, personalise the treatment intensity, and ensure you're doing the right exercises to reinforce healing. A course of shockwave alone will likely underperform compared to shockwave plus targeted rehab.

If you're unsure whether your condition is suitable, contact us for a confidential discussion. We can review your imaging and history to advise honestly on whether shockwave therapy is right for you, or recommend an alternative approach.

What Happens During a Shockwave Therapy Session?

A typical shockwave therapy session at CK Physio follows a structured pathway to ensure safety, efficacy, and comfort. Here's what you'll experience from arrival to aftercare.

Is Shockwave Therapy Painful?

This is the question we hear most. The answer: shockwave therapy is uncomfortable, but not unbearably painful, and the discomfort is brief and controllable.

During treatment, most patients report discomfort of 3–5 out of 10 on a pain scale, with radial shockwaves typically milder (2–4/10) than focused waves. The sensation is often described as a rhythmic tapping or deep pressure; it's not sharp or cutting. Your physiotherapist adjusts intensity throughout the session—if you signal discomfort, we dial it back. There's no medical benefit to suffering; in fact, intense pain may cause muscle guarding that reduces efficacy.

The first session is usually the most intense because tissue is tense and nerves are anticipating something unknown. By session two or three, your body adapts, tissues are more responsive, and the sensation feels less shocking. Many patients find that once they experience it once, they're surprised how manageable it is.

For a detailed exploration of pain during shockwave therapy and coping strategies, see our article Is Shockwave Therapy Painful?, which includes patient testimonials and our top tips for comfort during sessions.

After the session, you may experience mild tenderness in the treated area, similar to delayed-onset muscle soreness (DOMS) after intense exercise. This typically fades within 24–48 hours and is a sign that healing is activating.

How Does Shockwave Therapy Compare to Other Treatments?

When deciding on treatment for chronic pain, you likely have several options: physiotherapy, injections, surgery, or other modalities. Here's how shockwave therapy stacks up against the most common alternatives.

The Shockwave Edge: Shockwave therapy bridges the gap between temporary relief (injections, ultrasound) and invasive intervention (surgery). It's a middle path: effective, drug-free, and preserves your tissue. Unlike corticosteroid injections, which mask pain for a few months without addressing the root problem, shockwave therapy stimulates actual tissue repair. The benefits improve over 12 weeks and typically last 2–5 years. And unlike surgery, there's no downtime—you leave and get on with your day.

The Best Outcome: At CK Physio, we often recommend a combined approach. For example, a patient with plantar fasciitis might receive 2–3 shockwave sessions paired with a progressive strengthening programme, stretching, and potentially one anti-inflammatory injection early on. The injection provides quick pain relief; the shockwave triggers deep healing; and physio rebuilds foot mechanics. This integrated strategy outperforms any single modality.

How Much Does Shockwave Therapy Cost in London?

Shockwave therapy pricing in London varies by clinic, condition, and equipment. At CK Physio in West London (serving Hanwell, Ealing, and the surrounding area), our pricing is transparent and competitive.

Our Pricing

• Single Session: £140
• 3-Pack (3 sessions, £395 total): Save £25
• 6-Pack (6 sessions, £750 total): Save £90

Most patients see meaningful benefit from a 3-pack course. If you progress to a 6-pack, you're investing in a more comprehensive treatment plan, often combined with physiotherapy exercises and complementary modalities like acupuncture or electrotherapy.

Insurance & Private Medical Cover

Many private health insurance providers cover shockwave therapy as a condition of your policy, though some require a physiotherapy referral or pre-authorisation. Common providers that may cover ESWT include:

• BUPA
• AXA Health
• Aviva
• Cigna
• Simply Health

Check your policy: Contact your insurer directly to confirm whether shockwave therapy is covered and any conditions (e.g., prior physiotherapy attempts, referral requirement). We're happy to provide invoicing and clinical justification to support your claim. As an HCPC-registered clinic, we meet the standards insurers require.

NHS Availability

The NHS offers shockwave therapy in selected centres, usually orthopaedic departments in larger hospitals. Access is limited, waiting lists are long (often 3–6 months), and availability depends on your local integrated care board (ICB). Referral is typically via your GP to an orthopaedic consultant, not directly through physiotherapy. If you're keen to proceed quickly, private treatment—like ours—bypasses the waiting list entirely.

Value for Money

At £140 per session, you're paying for specialist equipment (a clinical-grade shockwave machine costs £30,000–£100,000), a trained physiotherapist, and integrated care. Compared to a corticosteroid injection (£150–£300, temporary 3–6 month benefit), shockwave offers comparable or better upfront cost and superior long-term value. Many patients avoid surgery costing £3,000–£8,000+, making shockwave extremely cost-effective as a first option.

Who Should Not Have Shockwave Therapy?

Shockwave therapy is very safe, but there are situations and conditions where it's not appropriate. We take a thorough history during your initial assessment to identify any contraindications and ensure your safety.

Absolute Contraindications

• Active Malignancy or History of Cancer: Shockwave-induced tissue stimulation could theoretically trigger or accelerate cancer growth. We avoid shockwave near or in regions with active cancer or high risk.
• Pregnancy: Safety data in pregnancy is limited. We do not treat pregnant patients.
• Cardiac Pacemaker or Implanted Defibrillator: Acoustic energy could interfere with device function.
• Severe Coagulopathy or Anticoagulation: Patients on warfarin or with severe bleeding disorders are at risk of excessive bruising or haematoma.
• Infection at the Treatment Site: We avoid shockwave over active cellulitis or infected wounds.

Relative Contraindications (Caution Required)

• Recent Steroid Injection (6–11 Weeks): Cortisone suppresses inflammation but also healing. If shockwave is given too soon after a steroid injection, efficacy may be reduced. We typically wait 6–8 weeks before treating the same area.
• Very Young Age (Skeletally Immature): Growth plates may be sensitive to high-energy stimulation. Shockwave is generally safe for adults; we use caution in adolescents near growth plates.
• Severe Osteoporosis: Bone fragility increases fracture risk if shockwave is applied over osteoporotic bone. We assess bone density and avoid high-energy focused waves in these cases.
• Neurological Compromise or Sensory Loss: Patients unable to report discomfort are at risk of inadvertent tissue damage. We need reliable feedback during treatment.
• On High-Dose Antiplatelet Therapy (e.g., Clopidogrel): Increased bruising risk, but treatment is often still safe with informed consent.

Even if you have a relative contraindication, treatment may still be possible with careful planning. For example, we can delay treatment after a steroid injection, reduce energy in osteoporotic patients, or position you to avoid pacemaker interference. The key is disclosure: tell us your full medical history, current medications, and any concerns. We'll make a shared decision based on your risk–benefit profile.

Reassurance on Safety: Across international trials and clinical practice, serious adverse events from shockwave therapy are extraordinarily rare (less than 0.1%). Common minor effects are temporary redness, mild bruising, or transient swelling—all expected and harmless. The CSP and NICE both consider ESWT a low-risk intervention when delivered by trained professionals.

Frequently Asked Questions About Shockwave Therapy

We've answered the questions we hear most often. If you have a question not covered here, please get in touch—we're happy to discuss your specific situation.

Q: How many shockwave sessions will I need?

A: Most conditions require 3–6 sessions, spaced 1–2 weeks apart. Plantar fasciitis often responds to 3 sessions; calcific tendinopathy may benefit from 4–5. Some conditions plateau after 3 sessions, while others progress steadily through 6. We reassess after every 2–3 sessions and adjust the plan based on your progress. If you're not improving, we'll discuss alternatives rather than continuing ineffectively.

Q: How long does it take to see results?

A: Some patients feel pain relief within 1–2 weeks of the first session. However, true tissue remodelling takes 8–12 weeks. The sweet spot for assessment is 6–8 weeks into a course—by then, inflammation has calmed and new blood vessel growth is evident on ultrasound. Don't judge efficacy on week two; judge it at week eight.

Q: Is shockwave therapy permanent?

A: Benefits typically last 12–24 months, often extending to 2–5 years with proper maintenance (exercise, activity modification, addressing biomechanical causes). Shockwave heals tissue, but if you return to the exact same activity pattern that caused the injury, pain can recur. The goal is lasting recovery through tissue healing plus behavioural change—and that's why our integrated physiotherapy approach is so important.

Q: Can I have shockwave therapy if I'm taking painkillers or NSAIDs?

A: Yes. You can take paracetamol or ibuprofen before or after shockwave therapy. However, high-dose chronic NSAID use can potentially dampen the inflammatory response that triggers healing. If you're on long-term NSAIDs, discuss with your physiotherapist—we may suggest a short course off medication to allow the healing cascade to activate. Always consult your GP before stopping medications.

Q: Will shockwave therapy interfere with my other treatments (injections, ultrasound, acupuncture)?

A: Shockwave integrates well with ultrasound and acupuncture—in fact, the combination often works better than either alone. However, we recommend waiting 6–8 weeks after a steroid injection before having shockwave to the same area, as cortisone can temporarily suppress the inflammatory response needed for shockwave to work. If you're considering both injections and shockwave, let us plan the sequence so they complement each other. Learn more in our detailed guide Benefits of Shockwave Therapy in Physiotherapy Treatment.

Q: Is shockwave therapy suitable for shoulder and neck pain?

A: Absolutely. Shockwave therapy is particularly effective for calcific tendinopathy of the shoulder (90.9% success with ultrasound guidance) and rotator cuff tendinopathy. Neck pain from chronic muscle tension also responds well to radial shockwave. Our article Innovations in Shockwave Therapy for Shoulder and Neck Pain explores these applications in detail. Anatomy matters: we ensure the applicator is positioned safely and precisely.
