About this study

Official title: Treatment of Plantar Fasciitis With Radial Shockwave Therapy vs. Focused Shockwave Therapy: a Randomized Controlled Trial

Inflammation of the plantar fascia is known as plantar fasciitis and is commonly seen in active or overweight individuals. It can be treated via conservative or surgical therapies. Extracorporeal shockwave therapy has shown promise in the treatment of plantar fasciitis. Several studies have compared the effects of different types of extracorporeal shockwave therapy (radial and focused) with other forms of conservative treatment in patients with chronic plantar fasciitis. No study has yet compared the effect of radial vs. focused shockwave therapy on pain in this population.

Read the detailed description

Plantar fasciitis is a common foot problem that affects 3.8 per 1,000 persons in the United States. It is characterized by inflammation of the plantar fascia, a fibrous tissue which connects the calcaneus to the metatarsal heads, and is often seen in individuals who are overweight and/or participate frequently in weight-bearing endurance activities such as running. Pain is typically at its highest during the first steps in the morning, although it can also occur with prolonged weightbearing. Plantar fasciitis can be treated via conservative or surgical measures, although surgery is considered as the last resort. In recent years, extracorporeal shockwave therapy has emerged as an alternative conservative method for treating plantar fasciitis. There are two types -- radial and focused shockwave therapy. Focused therapy creates deeper-penetrating, higher-energy shockwaves, whereas radial therapy produces more superficial shockwaves that can treat a wider area of pathology.

Randomized controlled trials have compared focused and radial shockwave therapy to placebo and other conservative measures in the treatment of chronic plantar fasciitis and overall demonstrated benefit. Only one study has directly compared radial and focused shockwave therapy in this population, although pain was not an outcome of focus in the study. The current study aims to collect patient-reported outcomes on both pain and function following radial vs. focused shockwave therapy vs. control therapy.

Being tested
Radial shockwave therapy, Focused shockwave therapy, Shockwave therapy device, Home therapy

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Radial shockwave therapyProcedure or surgery

    Target intensity will be within a range of 3.5-5.0 bar at maximum Hz, titrated up to patient tolerance within 100 pulses. Total of 3000 pulses.

  • Focused shockwave therapyProcedure or surgery

    Target intensity will be within a range of 0.15-0.25 mJ/mm2 at maximum Hz, titrated up to patient tolerance within 100 pulses. Total of 3000 pulses.

  • Shockwave therapy deviceDevice

    The shockwave therapy device will be used to administer either radial or focused shockwave therapy.

  • Home therapyOther

    Stretching and ice massage

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Visual analog scale pain - morning

    Morning pain. This will be assessed on a scale of 0-100, with a higher score representing more pain.

    Measured: Up to 1 year

  2. Visual analog scale pain - after prolonged walking or standing

    Pain after prolonged walking or standing. This will be assessed on a scale of 0-100, with a higher score representing more pain.

    Measured: Up to 1 year

Secondary outcomes (3)
  1. PROMIS Physical Function computer adaptive test score

    This computer adaptive questionnaire assesses physical function. A higher score represents higher function. A score of 50 represents the population average.

    Measured: Up to 1 year

  2. Foot and Ankle Outcome Score (FAOS)

    The FAOS assess pain, symptoms, activities of daily living, sports, and quality of life related to foot and ankle pain. This will be assessed on a scale of 0-100, where 100 indicates no problems and 0 indicates extreme problems.

    Measured: Up to 1 year

  3. Treatment satisfaction

    Satisfaction with the assigned treatment will be determined on a 0-10 scale, with 10 being most satisfied and 0 being least satisfied.

    Measured: Up to 1 year

Questions about this trial

What is this clinical trial studying?

A study testing Radial shockwave therapy, Focused shockwave therapy and Shockwave therapy device in people with Plantar Fascitis, run by Hospital for Special Surgery, New York at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 14 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: under way, not looking for participants, as of the sponsor's last update on 28 Apr 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Visual analog scale pain - morning (time frame: Up to 1 year). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 Apr 2026.
