Shockwave Therapy for Plantar Fasciitis: Does It Work?

Plantar heel pain — commonly called plantar fasciitis — is one of the most frequent musculoskeletal complaints seen in physiotherapy practice. For most people it resolves with appropriate management over weeks to months. For a significant minority, however, symptoms persist despite initial treatment, and it is in these cases that shockwave therapy is most commonly considered.

This article explains what plantar fasciitis is, how it is typically managed, and what the evidence shows for shockwave therapy as part of that management — including its limitations and what patients can realistically expect.

What Is Plantar Fasciitis?

The plantar fascia is a band of connective tissue that runs along the underside of the foot, from the heel bone (calcaneus) to the base of the toes. It supports the arch of the foot and absorbs load during walking and running.

Plantar fasciitis — more accurately described as plantar fasciopathy or plantar heel pain — involves pain and often tenderness at or near the attachment point of the fascia to the heel. Despite the "-itis" suffix, acute inflammation is not always the primary feature, and the condition is now understood to involve degenerative changes in the tissue alongside possible irritation.

It is particularly common in those who spend long periods on their feet, those returning to running after a break, and those who have recently increased their training load.

Common Symptoms

The hallmark symptom of plantar heel pain is discomfort at the underside of the heel that is typically worst:

• With the first steps in the morning
• After prolonged sitting or inactivity
• After — rather than during — activity
• On pressure to the medial aspect of the heel

Symptoms often improve with gentle movement as the tissue warms up, only to worsen again after activity. In more persistent cases, discomfort may be present throughout the day.

Assessment and Diagnosis

A clinical diagnosis of plantar heel pain is typically made on the basis of the patient's history and physical examination. Imaging such as ultrasound or MRI is not routinely required to make the diagnosis, though it may be used in specific circumstances — for example, to rule out other causes of heel pain or to assess the degree of fascial thickening.

At Lambert Sports Clinic, the assessment also considers contributing factors such as calf and foot flexibility, foot strength, footwear, training load and activity demands, as these influence the treatment plan.

Conservative Treatment

For most patients, plantar heel pain responds well to a combination of:

• Load management — temporarily modifying activities that aggravate symptoms
• Calf and foot stretching
• Foot and calf strengthening exercises, including progressive heel raises
• Footwear advice and, where appropriate, insoles or orthotics
• Gradual return to full activity

Patience is important. Plantar fasciitis can take several months to resolve fully, and it is normal for progress to be non-linear.

When Is Shockwave Therapy Considered?

Shockwave therapy for plantar fasciitis is typically considered when:

• Symptoms have been present for three months or more
• Conservative management including exercise rehabilitation has been consistently applied
• Symptoms have not adequately improved despite appropriate treatment
• Clinical assessment suggests suitability for shockwave

It is not the first treatment of choice, and it is not appropriate for every patient or every presentation of heel pain.

What Does the Evidence Show?

Of all the conditions assessed for shockwave therapy, plantar fasciitis has one of the more substantial evidence bases. A number of randomised controlled trials and systematic reviews have compared shockwave with sham (placebo) treatment and with other conservative interventions.

Several reviews have found that shockwave therapy may be associated with greater reductions in pain and improvements in function compared with placebo in patients with persistent plantar heel pain, particularly at medium-term follow-up. The evidence appears stronger for patients who have had symptoms for a longer period.

However, important caveats apply:

• The quality of individual studies varies, and results are not entirely consistent across the literature.
• Comparison groups and outcome measures differ between studies, making direct comparisons difficult.
• Not all patients in positive trials responded — a proportion derived little benefit.
• Long-term outcomes are less well characterised.

The overall position of shockwave for plantar fasciitis in UK clinical guidance is that it may be considered as a treatment option for patients with persistent symptoms who have not responded to conservative management. It is not considered a first-line treatment.

Realistic Expectations

Patients considering shockwave therapy for plantar fasciitis should understand the following:

• Not every patient responds to shockwave therapy.
• Improvement, when it occurs, is typically gradual — changes are often noticed over weeks rather than immediately after a session.
• A temporary increase in symptoms in the 24–48 hours after each session is normal and expected.
• Exercise rehabilitation remains essential — shockwave is not a replacement for foot strengthening and calf loading.
• Multiple sessions are usually required.
