This guide provides physiotherapist-led information on shockwave therapy for Achilles tendinopathy, including how ESWT works, what the evidence shows, and what a course of treatment at Optimove Clinic involves.
Achilles tendinopathy is one of the most common overuse injuries in active adults — and one of the conditions where shockwave therapy has the strongest clinical evidence. Whether you are a runner, a gym-goer, or someone who has spent months trying rest and physiotherapy without lasting relief, this guide explains how shockwave therapy for Achilles tendinopathy works, what the research shows, and what a course of treatment at Optimove Clinic involves.
Understanding Achilles Tendinopathy
The Achilles tendon connects the calf muscles to the heel bone (calcaneus) and is placed under considerable repetitive load during walking, running, and sport. When that load exceeds the tendon’s capacity to recover — due to a sudden increase in training volume, inadequate recovery, or age-related changes in tissue quality — the tendon undergoes a degenerative process rather than a true inflammatory one.
Understanding this is important: Achilles tendinopathy is not simply a tendon that is inflamed. It is a tendon in which the normal collagen structure has been disrupted. This explains why anti-inflammatory treatments such as NSAIDs and steroid injections frequently provide only short-term relief, and why treatments that stimulate the tendon’s own repair response — such as progressive loading and shockwave therapy — tend to produce more durable outcomes.
Mid-Portion vs Insertional Achilles Tendinopathy
Not all Achilles tendinopathy is the same, and the distinction between mid-portion and insertional presentations matters significantly for treatment.
Two distinct presentations:
- Mid-portion Achilles tendinopathy occurs 2–7 cm above the heel bone. It is the more common presentation and tends to respond well to both progressive loading programmes and shockwave therapy
- Insertional Achilles tendinopathy occurs at the point where the tendon attaches to the calcaneus. It is more complex mechanically and often more resistant to standard loading protocols. Shockwave therapy can still be effective, but the treatment protocol — including probe positioning and energy settings — must be adapted accordingly
At Optimove Clinic, every patient is assessed clinically to confirm the location and staging of their tendinopathy before treatment begins. This ensures the correct shockwave protocol is applied.
Why Achilles Tendinopathy Becomes Persistent
Achilles tendinopathy follows a continuum of three stages: reactive tendinopathy, tendon dysrepair, and degenerative tendinopathy. In the early reactive stage, load modification and relative rest can be effective. However, once the tendon has progressed to the dysrepair or degenerative stage — characterised by failed healing, disorganised collagen, and abnormal blood vessel in-growth — passive rest alone is rarely sufficient.
This is the patient population who often arrives at our clinic: individuals who have rested for weeks or months, reduced their activity, and still find their Achilles painful the moment they return to exercise. For a clinical overview, the NHS patient information page on Achilles tendinopathy provides a useful introduction.
How Shockwave Therapy Helps Achilles Tendinopathy
Shockwave therapy delivers high-energy acoustic waves into the affected tendon tissue via a handheld probe. For Achilles tendinopathy, the probe is applied directly over the area of maximum tenderness — at the mid-portion or insertion, depending on the patient’s presentation.
The mechanical stimulus works through several mechanisms:
- Stimulates the production of collagen and growth factors within degenerate tendon tissue
- Disrupts abnormal calcium deposits that can form within the tendon
- Reduces local pain hypersensitivity by modulating nociceptive nerve fibres
- Improves tendon load tolerance, making subsequent progressive loading exercises significantly more effective
💡 Clinical Insight: Shockwave therapy works best when combined with a structured progressive loading programme — such as heavy slow resistance (HSR) training or the Alfredson eccentric protocol. Neither treatment alone is as effective as the two combined. Shockwave reduces pain and stimulates repair; loading drives collagen remodelling and tendon adaptation.
What the Evidence Shows for Achilles Tendinopathy
Mid-Portion Achilles
The evidence base for shockwave therapy in mid-portion Achilles tendinopathy is strong and well-established. Multiple randomised controlled trials (RCTs) and systematic reviews have demonstrated clinically significant improvements in pain scores and functional outcomes compared with placebo and other conservative treatments.
Studies consistently show that patients who have failed to respond to an exercise programme alone experience meaningful recovery when shockwave is added. Response rates in the literature typically range from 60 to 80 per cent, with many patients reporting significant improvement by the end of a three-session course. The ISMST (International Society for Medical Shockwave Treatment) consensus guidelines provide a regularly updated evidence review for Achilles tendinopathy.
Insertional Achilles
The evidence for insertional Achilles tendinopathy is more moderate but still supportive. The treatment is technically more challenging — the probe must be positioned to avoid direct pressure on the heel bone, and energy settings are typically adjusted to account for the bony insertion site.
In clinical practice, a meaningful proportion of insertional patients do respond to a modified shockwave protocol, particularly those who have not responded to conservative loading alone. Results are less consistent than for mid-portion presentations, and realistic expectations are discussed candidly at your first appointment.
Treatment Protocol for Achilles Tendinopathy
Every patient at Optimove Clinic undergoes a thorough assessment before shockwave therapy begins. This confirms the location and stage of the tendinopathy, rules out contraindications, and determines whether imaging (ultrasound or MRI) is advisable — particularly to exclude a partial or complete tendon tear, for which shockwave would not be appropriate.
A typical treatment course involves:
- 3 to 6 sessions, scheduled weekly or every 5 to 7 days
- Each session lasts 15 to 30 minutes, including assessment and post-treatment guidance
- Energy levels are adapted to the stage of the condition and the patient’s tolerance
- Post-session soreness of 24 to 48 hours is expected and considered part of the treatment response
- Graduated loading exercises continue throughout the treatment course
- High-impact activity (running, jumping) should be avoided for 48 hours after each session
- Improvement is often noticeable within 2 to 3 sessions, with continued progress over the following weeks
Shockwave Therapy vs Other Achilles Treatments
vs Rest and Ice
For an acute reactive presentation — typically associated with a sudden spike in training load and pain present for less than three months — load modification, temporary rest, and activity adjustment are appropriate first-line measures. These interventions can calm the tendon’s reactive response and are a necessary starting point.
However, for chronic degenerative tendinopathy, passive rest does not address the underlying structural changes in the tendon. Patients who have already rested extensively without resolution are typically not going to improve further with more rest. This is where shockwave therapy becomes a key treatment option.
vs Steroid Injections
⚠️ Clinical Note: Corticosteroid injections carry a recognised risk of Achilles tendon rupture and are generally not recommended for Achilles tendinopathy by current clinical guidelines. If you have been offered a steroid injection for Achilles pain, we strongly advise discussing the risk profile with the treating clinician. Shockwave therapy is a considerably safer alternative for this location.
In contrast to steroids, shockwave therapy carries no systemic effects and does not weaken tendon tissue. Its mechanism of action is reparative rather than suppressive.
vs Surgical Debridement
Surgery for Achilles tendinopathy — typically involving debridement of degenerate tendon tissue — is reserved for end-stage cases that have failed all conservative management, usually after a period of 12 or more months. Shockwave therapy is one of the most effective conservative options available and should be trialled before any surgical referral is considered.
Who Is Suitable for Shockwave Therapy for Achilles Pain?
Good candidates typically include those who:
- Have mid-portion or insertional Achilles tendinopathy confirmed on clinical assessment
- Have had symptoms for three months or longer (chronic tendinopathy)
- Have had a partial or no response to a progressive loading programme alone
- Have no contraindications to treatment
Standard contraindications include:
- Pregnancy
- Local skin infection at the treatment site
- Anticoagulant therapy (e.g. warfarin)
- Certain bone tumours or metabolic bone conditions
⚠️ Important: Shockwave therapy is not appropriate for partial or complete Achilles tendon tears. If there is any clinical suspicion of a structural tear — sudden onset of severe pain, loss of plantarflexion strength, or a palpable gap in the tendon — imaging should be reviewed before treatment is considered.

Frequently Asked Questions
How many sessions of shockwave therapy do I need for Achilles tendinopathy?
Most patients require between 3 and 6 sessions, delivered weekly. Mid-portion presentations typically respond within 3 to 4 sessions. Insertional cases may require the full 6 sessions and a slightly modified protocol. Your physiotherapist will reassess your progress throughout and advise accordingly.
Can I run during a course of shockwave therapy?
In most cases, yes — but with modifications. We advise avoiding high-impact activity for 48 hours after each session to allow the initial treatment response to settle. Between sessions, you can continue graduated running or jogging provided your symptoms remain manageable.
Does shockwave therapy hurt for Achilles pain?
Shockwave treatment typically causes a tolerable aching or buzzing sensation during the session. The area being treated is often tender, so some discomfort is expected — particularly over the most reactive part of the tendon. The intensity is adjusted to your tolerance throughout. Post-session soreness lasting 24 to 48 hours is normal and indicates the treatment is working.
How long until my Achilles feels better after shockwave?
Many patients notice a meaningful reduction in pain within 2 to 3 sessions. However, the full tissue-level repair process continues for weeks to months after treatment ends. It is common to feel significantly better by the end of a 6-week course, with continued improvement over the following 3 to 6 months as the tendon remodels and strengthens through progressive loading.
Is shockwave therapy safe for Achilles tendon problems?
Yes. Shockwave therapy has an excellent safety record for Achilles tendinopathy. Unlike corticosteroid injections, it does not carry a risk of tendon weakening or rupture. Side effects are limited to temporary localised soreness and, occasionally, minor skin redness at the treatment site. It is not appropriate for partial or complete tendon tears — your clinician will screen for these at assessment.
📌 Key Takeaways
- Achilles tendinopathy is a degenerative condition, not simply an inflammatory one — which is why passive rest and anti-inflammatories frequently fail
- Shockwave therapy stimulates collagen production, disrupts calcium deposits, and reduces pain hypersensitivity in degenerate tendon tissue
- Mid-portion presentations have the strongest evidence base, with response rates of 60–80% in the literature
- ESWT is most effective when combined with a progressive loading programme — the two together produce significantly better outcomes than either alone
- Treatment courses typically involve 3 to 6 weekly sessions from £53.75, with no GP referral required
- Shockwave is not appropriate for partial or complete tendon tears — assessment confirms suitability before treatment begins
