Acoustic Wave Therapy

Overview

Acoustic wave therapy (also called shockwave therapy) is a treatment that sends short pulses of sound energy through the skin into a painful area. It is not surgery and usually needs no needles or cuts. A handheld device is pressed against your skin and delivers the pulses, often in a clinic or physiotherapy setting. The idea is that these pulses can stir up healing, ease pain and loosen tight or damaged tissue. It is used most often for long-lasting tendon problems — such as heel pain (plantar fasciitis), tennis elbow and shoulder tendon pain — and in some specialist clinics for certain men's health concerns. It is a treatment, not a diagnosis, so whether it helps depends on what is causing your symptoms.

It is fairly common in physiotherapy and sports medicine clinics, and increasingly offered in private settings. How often it is used varies a lot between countries and clinics, and some claims made for it are better supported by research than others.

It is mostly used in adults with long-standing tendon or joint pain that has not settled with simpler treatments. It is not usually offered to children, whose growing bones and joints need a different kind of assessment. Older adults can have it too, but other causes of pain — such as arthritis or nerve problems — should be checked first.

Symptoms

Common symptoms

• Pain in the heel or sole of the foot that is worst with the first steps in the morning
• Pain on the outside of the elbow that gets worse when gripping or lifting
• Shoulder pain when reaching overhead, sometimes with calcium deposits seen on a scan
• Pain in a tendon that has lasted weeks or months and improves only partly with rest
• Stiffness or aching in the affected area after activity
• Pain that has not settled despite physiotherapy, exercises or changes to your footwear

Symptoms in children

• Children's heel, knee or elbow pain is usually assessed differently, because growing bones can be the cause
• Acoustic wave therapy is not routinely offered to children, so a child with lasting limb pain should see a doctor or physiotherapist first

Symptoms in older adults

• Tendon pain that lasts longer or returns more easily
• Pain that may be mixed with arthritis or nerve changes, which need to be checked before any treatment is planned
• Thinner skin and poorer circulation, which means the clinician may adjust how the treatment is given

Causes

Main causes

• Overuse or repeated strain on a tendon, common in running, racket sports or physically demanding jobs
• Tendon wear and tear over time, where the tissue becomes thickened and less able to repair itself
• Calcium deposits forming in a tendon, especially around the shoulder
• Scar tissue or poor blood flow in a tendon after an old injury
• In some clinics, reduced blood flow and tissue changes linked to erectile difficulties or scarring conditions in men

Risk factors

• A job or sport that involves repetitive gripping, jumping or overhead reaching
• Sudden increases in training amount or intensity
• Diabetes, high cholesterol or smoking, which can affect healing and blood flow
• Being overweight, which adds load to the feet, knees and hips
• Certain medicines, such as some antibiotics and steroids, that can affect tendons — ask your pharmacist or doctor
• Getting older, as tendons lose some of their ability to bounce back

When to see a doctor

See a doctor urgently if:

• You cannot put weight on the leg or use the arm at all
• The area is hot, very swollen or red, or you have a fever
• You have sudden numbness, weakness or loss of feeling in the limb
• You had a session and the treated area is becoming more painful, swollen or blistered

Book a routine appointment if:

• Pain has lasted more than a few weeks or keeps coming back
• Simple measures such as rest, ice, stretching and changes to footwear are not helping
• You want to know whether acoustic wave therapy is suitable for you
• You are considering paying for treatment privately and want an independent opinion first
• You have diabetes, a bleeding disorder, a pacemaker or you take blood thinners, as these need to be discussed before treatment

Diagnosis

The clinician starts by asking about your pain, how it started, what makes it better or worse, and what you have already tried. They will feel and move the affected area to check where the pain comes from and how the joint moves. Imaging may be suggested, but scans are used mainly to rule out other problems or to guide treatment, not to confirm that acoustic wave therapy is right for you.

Tests that may be done

• A physical examination of the painful area, including movement and strength testing
• Ultrasound scan, which can show tendon thickening or calcium deposits
• X-ray if a bone problem or calcium deposit is suspected
• MRI scan in some cases, usually if surgery is being considered or the diagnosis is unclear
• Blood tests occasionally, if an inflammatory or metabolic condition is suspected

What to expect at your appointment

A typical first appointment takes 20 to 30 minutes. You may be asked to wear loose clothing so the area can be examined. If a scan is arranged, it is usually quick and painless. You should leave with a clear explanation of the likely cause of your pain and a plan that may include exercises, activity changes, or a referral for further treatment.

Treatment

Treatment for tendon and soft-tissue pain usually starts with the simplest, safest steps: adjusting activity, doing the right exercises, and giving the tissue time and the right load to heal. Acoustic wave therapy is an add-on option for people whose pain persists. It is given in sessions, usually once a week for about three to six weeks, and is often combined with an exercise programme rather than used on its own.

Self-care at home

• Rest the area from the activity that triggers pain, but keep moving gently so the joint does not stiffen
• Use ice or a cold pack for 10 to 15 minutes at a time, wrapped in a cloth, if there is swelling
• Follow a graded exercise programme from a physiotherapist — slow, steady loading is better than sudden bursts
• Check your footwear: supportive, cushioned shoes can reduce heel and foot pain
• Pace yourself: break up heavy tasks and avoid big jumps in how much you do
• Keep a simple note of your pain levels so you and your clinician can see whether things are improving

Medical treatments

Your clinician may suggest a combination of approaches: physiotherapy and a tailored exercise plan, advice about activity and footwear, and pain relief options discussed with your pharmacist or doctor. Some people are offered injections into the tendon, but these are not suitable for everyone and carry some risk, so they are a decision to make with your clinician. Acoustic wave therapy is delivered by a trained practitioner using a handheld device; you may feel tapping, a warm sensation, or mild discomfort during the session, and the area can be tender for a day or two afterwards. Other treatments, such as ultrasound therapy or laser, are also used in some clinics, but the evidence for each varies. No single treatment works for everybody.

When is surgery considered?

Surgery is usually considered only when pain has lasted many months, other treatments have not helped, and scans show a problem that surgery could fix. It is a bigger step with longer recovery, so your clinician will explain the risks and benefits, and you may be referred to a specialist to discuss it.

Living with this condition

Ongoing tendon pain can be frustrating, especially when it affects work, sleep or the things you enjoy. The good news is that most people improve with a steady, patient approach. Build small amounts of activity into each day rather than saving everything for the weekend, and expect good days and bad days along the way.

Lifestyle tips

• Warm up before exercise and increase your training gradually rather than in big leaps
• Vary your activities so the same joint is not repeated every day
• Take short breaks from repeated gripping, typing or standing, and stretch gently
• If you smoke, getting support to stop can help your body heal — ask your doctor or pharmacist
• Aim for regular sleep, as rest is when tissue repairs itself

Diet and exercise

A balanced diet with enough protein, vitamin C and vitamin D supports tissue repair. There is no special diet for tendon pain, but staying at a healthy weight reduces strain on the feet, knees and hips. Gentle strengthening exercises, such as slow heel raises or light resistance work, are often the most helpful thing you can do — a physiotherapist can show you how to start safely and build up over weeks.

Mental health and emotional wellbeing

Long-lasting pain can affect mood, sleep and confidence, and it is common to feel low or anxious about it. These feelings are understandable and worth mentioning to your clinician. If you are struggling with your mental health, talk to your doctor or a local mental health service, and if you ever feel unsafe or in crisis, contact your local emergency number or a crisis line in your country straight away.

Prevention

You cannot always prevent tendon problems, but you can lower the risk. Build up activity gradually, use good technique, wear supportive footwear and give your body enough rest between demanding days. If you have had tendon pain before, a maintenance exercise routine can help keep it from coming back.

Screening programmes

There is no routine screening test for tendon problems. If you have a long-term condition such as diabetes that affects healing, regular check-ups with your doctor are a good way to catch problems early.

Complications

If left untreated

• Pain may continue or become more constant, making everyday tasks harder
• Weakness and reduced movement in the affected joint
• Changes to how you walk or use your arm, which can cause pain elsewhere
• Poor sleep, low mood and time off work or sport
• In rare cases, a tendon can tear — this usually causes sudden severe pain and needs urgent medical review

Long-term outlook

Most people with tendon and soft-tissue pain do get better, often over weeks to a few months, especially with a steady exercise plan. Acoustic wave therapy helps some people and not others, so it is best seen as one possible part of a wider plan. Keep talking to your clinician about how things are going, and be patient with yourself — slow progress is still progress.
