Who is the Best & Worst Candidate for Shockwave Therapy?

Shockwave therapy has become a popular treatment for people with persistent tendon, muscle, and soft tissue pain. It is commonly used in physiotherapy clinics for conditions such as plantar fasciitis, Achilles tendinopathy, tennis elbow, and chronic shoulder pain. However, while it can be highly effective for certain patients, it is not suitable for everyone.

Understanding who is likely to benefit, and who may be a poor candidate, can help you decide whether this treatment fits your condition, one of the specialised services offered through shockwave therapy at Synapse.

What Is Shockwave Therapy?

This treatment is a non-invasive approach using mechanical sound waves to deliver energy into targeted areas of the body. Depending on the device and condition, the energy can be focused on or around painful tissues.

It is thought to stimulate the body’s natural healing response, improve local blood flow, influence pain sensitivity, and encourage tissue remodelling, and is particularly useful for chronic musculoskeletal conditions that have not responded to conventional treatment.

Importantly, it is usually not a standalone solution. It is often combined with exercise, strengthening, activity modification, and other physiotherapy interventions through sport physiotherapy.

The Best Candidates

1. People With Chronic Tendon Problems

One of the strongest candidates is someone with a persistent tendinopathy. Conditions such as Achilles tendinopathy, patellar tendinopathy, tennis elbow, and rotator cuff-related shoulder pain may respond well, particularly when symptoms have persisted for weeks or months.

These conditions often involve changes in tendon structure and load tolerance rather than an acute injury, so this treatment may be considered as part of a broader rehabilitation programme.

2. People With Plantar Fasciitis

Plantar fasciitis is another common condition treated this way. Patients often experience heel pain most noticeable during their first steps in the morning or after prolonged sitting. When symptoms persist despite stretching, strengthening, footwear changes, and activity modification, this treatment may be a useful option.

3. People Who Have Tried Conservative Treatment

This treatment is generally more appropriate once a patient has already attempted appropriate conservative management, such as:

• Exercise and strengthening
• Stretching
• Activity modification
• Load management
• Manual therapy
• Appropriate footwear or equipment changes

If someone has only had symptoms for a few days and has not yet tried basic rehabilitation, jumping straight to this treatment may not be necessary.

4. People With Realistic Expectations

A good candidate understands that this treatment is not a magic solution. It may reduce pain and support recovery, but improvement is not necessarily immediate. Some patients require several sessions, and the response can vary depending on the condition, severity, duration of symptoms, and overall rehabilitation programme.

5. People Who Can Participate in Rehabilitation

This treatment works best when the underlying problem is also addressed. Someone with Achilles tendinopathy, for example, may need structured strengthening to gradually improve the tendon’s capacity to tolerate load. If a patient actively participates in rehabilitation, it can be incorporated into a more complete treatment plan.

Who May Be a Poor Candidate?

1. People With Certain Medical Conditions

This treatment may not suit people with certain medical conditions or circumstances. It may be avoided over areas with active infection, significant tissue damage, or serious underlying conditions, and those with bleeding or clotting problems may need additional assessment first. This is why a proper physiotherapy assessment matters before starting treatment.

2. People With an Acute Injury

This treatment is often associated with chronic musculoskeletal problems, so it may not be the first choice for every acute injury. Someone who has just sustained a significant muscle or tendon injury may need a different approach early on, prioritising protection, load management, and gradual rehabilitation instead.

3. People Who Expect Instant Results

If someone expects one session to completely eliminate their pain, this treatment may not meet their expectations. Some people notice improvement relatively quickly, while others require more time, and temporary soreness following treatment can also occur. A successful plan should focus on gradual improvement in pain, function, and activity tolerance rather than chasing immediate relief.

4. People Who Ignore the Underlying Cause

This treatment cannot compensate for continuously overloading an injured area. A runner with Achilles pain who keeps dramatically increasing their running volume may struggle to recover even with treatment. The approach should always be combined with strategies that address the factors contributing to the problem.

5. People With an Incorrect Diagnosis

Perhaps the most important consideration is whether this treatment is actually appropriate for the condition. Not every painful area is caused by tendinopathy or another condition that responds well to it, since pain can originate from joints, nerves, muscles, or other structures covered under Synapse’s conditions treated. A thorough assessment should always come before treatment.

Is This Treatment Painful?

This treatment can feel uncomfortable, particularly when applied directly to a sensitive area, though intensity can usually be adjusted according to the patient’s tolerance. Some patients describe the sensation as tapping, pressure, or a sharp but manageable discomfort.

After treatment, temporary soreness or tenderness may occur. According to NICE, the UK’s National Institute for Health and Care Excellence, current evidence on extracorporeal shockwave therapy for conditions such as refractory plantar fasciitis raises no major safety concerns, though outcomes can vary between patients, which is why treatment should be guided by proper clinical assessment.

What Makes Someone an Ideal Candidate?

The ideal candidate is not simply someone who has pain. They are usually someone with an appropriate diagnosis, persistent symptoms, realistic expectations, no major contraindications, and a willingness to participate in rehabilitation.

A patient with several months of plantar fasciitis who has already tried appropriate exercises and activity modification may be a reasonable candidate. Someone who developed mild heel pain two days ago and has not yet attempted basic conservative treatment, on the other hand, may not need this treatment immediately.
