Does shockwave therapy work?
Sometimes, for selected conditions—but “shockwave therapy” is not one uniform treatment. The most consistent clinical signal is in chronic or refractory plantar fasciopathy. Recent meta-analyses do not support routine use for midportion or insertional Achilles tendinopathy, and patellar tendon outcomes are not consistently better than sham treatment when both groups load the tendon. Focused and radial devices are physically different, yet current direct comparisons do not establish an overall winner.
Focused energy density and radial pressure in bar cannot be converted into equivalent doses reliably.
Devices, energies, impulses, intervals, localisation, anaesthesia and concurrent rehabilitation vary widely.
Cell and animal findings make mechanotransduction plausible but do not prove human tendon regeneration.
Several statistically significant findings remain smaller than accepted thresholds for meaningful change.
Method and limits
The clinical question covered adults with musculoskeletal conditions receiving focused ESWT or radial pressure wave therapy, compared with sham, exercise/loading, injection, physiotherapy, surgery or observation. Outcomes included pain, function, imaging, return to activity, bone union and adverse events.
PubMed/MEDLINE, full text available through PubMed Central or Europe PMC, NICE guidance and reference lists from systematic reviews were searched. Institutional guidance, systematic reviews, meta-analyses and randomised trials were prioritised; cell and animal studies were separated from clinical efficacy.
This is a critical evidence review, not a formal systematic review. It did not use duplicate independent screening, a preregistered protocol or a complete multibase search of Embase, CINAHL and SPORTDiscus. The 38-paper set is curated and traceable, not claimed to be exhaustive.
Focused and radial therapy are not the same intervention
| Feature | Focused ESWT | Radial pressure wave |
|---|---|---|
| Generation | Electrohydraulic, electromagnetic or piezoelectric | Pneumatic/ballistic projectile striking an applicator |
| Distribution | Defined focus with greater potential depth | Highest pressure near the applicator with radial dispersion |
| Typical reporting | Energy-flux density (mJ/mm²), impulses, Hz, focal depth | Pressure (bar), impulses, Hz, applicator |
| Potential use | Deeper or precise target; higher-energy calcification or bone applications | Broader, more superficial treatment area |
| Comparative evidence | A 2026 systematic review found no clear general superiority for pain or function; certainty was low or very low. | |
The term “shockwave” is commonly used for both, although radial waves do not share all physical characteristics of a focused shockwave. Counting sessions or impulses alone therefore does not establish an equivalent dose. See van der Worp et al. and the 2026 radial-versus-focused meta-analysis.
Collagen remodelling: plausible mechanism, unproven clinical claim
Human tenocyte cultures have shown greater proliferation and type-I collagen synthesis after shockwave exposure, and tendon-derived cells have shown changes in migration and tenogenic markers. Animal models describe angiogenesis, matrix changes and improved fibrillar alignment during repair. These findings support biological plausibility.
What they do not prove
They do not demonstrate that pain or function improves because a human tendon has been molecularly “regenerated”. They also do not establish an optimal human dose or show that focused therapy regenerates tissue better than radial therapy. Imaging changes in thickness or signal are not molecular evidence.
The mechanistic evidence includes three-donor human tenocyte work, cells from ruptured human tendons, a pony tendon study that also found acute matrix disruption, and a rat Achilles model.
Evidence by condition
| Condition | Current classification | Critical interpretation |
|---|---|---|
| Chronic/refractory plantar fasciopathy | Useful in context | Repeated favourable pain/function signals, but substantial protocol heterogeneity and cautious NICE guidance. |
| Midportion Achilles tendinopathy | Not routine | Two 2026 meta-analyses found no clinically important overall benefit over sham/control. |
| Insertional Achilles tendinopathy | Not routine | A 119-participant blinded trial found no added benefit over sham plus eccentric exercise. |
| Patellar tendinopathy | Not routine add-on | Not consistently superior to sham when both groups perform tendon loading. |
| Calcific rotator cuff tendinopathy | Selected cases | Signals for pain, function and calcium resorption, but GRADE certainty is very low and needling/lavage may outperform it. |
| Non-calcific rotator cuff tendinopathy | Not routine | Small short-term pain effect without durable function benefit. |
| Lateral elbow tendinopathy | Second line / uncertain | Some statistical effects, but overall differences are often below clinically important thresholds. |
| Greater trochanteric pain syndrome | In research | Small pain effect; most trials in the 2024 review had high risk of bias. |
| Delayed union/nonunion | Specialist research | Promising, but evidence is dominated by non-randomised studies and cannot replace surgical assessment generally. |
Plantar fasciopathy
A 2024 meta-analysis and meta-regression of 11 randomised trials found pain improvements with both focused and radial treatment, while protocol parameters influenced outcomes and tolerability. A separate 16-study review favoured ESWT over corticosteroid injection at three and six months for some pain and function outcomes. However, another 14-trial analysis found only a small reduction in plantar fascia thickness and no significant pain advantage over other non-surgical interventions. NICE still describes efficacy as inconsistent and recommends governance, consent and audit or research. Lippi et al. · Cortés-Pérez et al. · Simental-Mendía et al.
Achilles tendinopathy
Older trials and a 2022 review suggested benefit in some midportion protocols. The current picture is less favourable: a 2026 analysis of nine trials and 557 participants found no clinically meaningful improvement and argued against routine use, while a second 2026 sham-controlled meta-analysis of eight trials and 458 participants also found no overall benefit. The apparent signal in symptoms under 12 months was exploratory. Korakakis et al. · Ni et al.
Patellar tendon, lateral elbow and shoulder
A network meta-analysis of 37 patellar tendinopathy trials found that ESWT was not superior to sham when eccentric loading was shared. For lateral elbow tendinopathy, several statistical differences exist, but pooled effects are commonly below clinically important change; corticosteroid injection may act faster, while ESWT may perform better at later follow-up. In calcific shoulder disease, higher-energy focused treatment may improve pain, function and resorption, but the 2024 review rated certainty very low. Cochrane found few clinically important benefits across rotator-cuff disease overall. Challoumas et al. · Karanasios et al. · Brindisino et al. · Cochrane review.
Protocols studied—not universal prescriptions
| Indication | Examples used in trials | Important limitation |
|---|---|---|
| Plantar fasciopathy | 1,500–3,000 impulses; 3–5 sessions, often weekly; focused or radial | Very wide variation in energy, localisation and comparator; optimal parameters remain unknown. |
| Midportion Achilles | Radial: 2,000 impulses, 8 Hz, 3 bar, three weekly sessions in classic trials | Recent meta-analyses do not support routine use despite early positive studies. |
| Insertional Achilles | About 2,000 impulses at 2.5–3 bar, three sessions; sometimes combined with eccentric exercise | A large blinded trial found no added benefit over sham plus exercise. |
| Patellar tendon | Focused 1,000–2,000 impulses at about 4 Hz, or radial 2,000 at about 8 Hz; three weekly sessions | No consistent advantage over sham when loading is maintained. |
| Lateral elbow | Focused 2,000 at about 0.2 mJ/mm², or radial 2,000–4,000 at about 2.5 bar; three sessions | Direct comparisons are small and low-certainty. |
| Calcific shoulder | Focused 1,500 at about 0.3 mJ/mm², or radial 2,000 at about 2.5 bar; 3–4 sessions | Higher energy appears more effective, but certainty remains very low. |
| Bone nonunion | Image-guided, high-energy focused protocols; one or more sessions | Specialist indication; tendon protocols must not be extrapolated. |
Do not convert bar into mJ/mm²
Actual energy delivery depends on the device, generator, applicator, focal depth, coupling and tissue. “Three sessions” is a common research schedule—not a proven optimum. Local anaesthesia and concurrent rehabilitation also vary and may influence outcomes.
Safety, contraindications and uncertainty
Commonly reported effects are pain during or after treatment, erythema, bruising or haematoma, superficial swelling and transient tingling or numbness. Headache or migraine is less common. A 2026 Achilles review reported two tendon ruptures after focused treatment; the available study designs cannot establish causality or estimate a reliable treatment-specific absolute risk.
Reviews and ISMST-derived practice guidance commonly identify pregnancy, active infection or osteomyelitis, malignancy in the focus and significant coagulopathy as contraindications or major precautions. High-energy treatment should not be directed at lung/pleura, brain, major nerves or an open growth plate. Anticoagulation, implanted devices, recent corticosteroid injection and local neurovascular anatomy require individual assessment.
Advice to avoid anti-inflammatory medication, ice or intense exercise immediately after treatment appears in practice reviews, but it does not have the same evidence strength as anatomical exclusions or bleeding risk.
Clinical boundary
This review is educational. It does not diagnose a condition, select a device, prescribe energy or determine whether shockwave treatment is appropriate for an individual.
Eight interpretation errors to avoid
- Calling pain reduction “regeneration”.
- Inferring molecular collagen remodelling from ultrasound thickness.
- Combining midportion and insertional Achilles disease.
- Treating radial and focused parameters as equivalent doses.
- Using a weak comparator to claim general clinical superiority.
- Equating statistical significance with meaningful benefit.
- Ignoring loading programmes, anaesthesia, ongoing sport and symptom duration.
- Turning a published trial protocol into an individual prescription.
