Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This pilot study aimed to test whether adding platelet-rich plasma (PRP) to shockwave therapy helps active soldiers with long-lasting plantar fasciitis more than shockwave alone. The trial was withdrawn before enrolling any participants, so no data were collected. The goal was to reduce first-step pain and improve function.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
platelet rich plasma (PRP) and extracorporeal shock wave therapy
What this could lead to
If it had worked, this could have pointed toward a more effective treatment for stubborn heel pain in active people.
What could go wrong
The trial was withdrawn before enrolling anyone, so no results are available. It is unclear if PRP adds any benefit over shockwave alone.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * 18 years or older * Patients that are already selected for ESWT for the treatment of resistant plantar fasciitis as part of clinical care under the doctor-patient relationship * X-ray imaging studies (Plain radiographs) documenting no additional sources for heel pain within 12 months(all x-rays were conducted as part of standard of care and no radiation will be specific to the research study) * Active Duty Soldier as they are a high demand cohort with increased frequency of plantar fasciitis compared to the general population as outlined by Scher et al. * Previously tried conservative management meeting referral to Orthopaedics: Pain medications, taping, orthoses, night splinting or physical therapy * Body Mass Index (BMI) \<40kg/m2 Exclusion Criteria: * • History of trauma\* or previous injury to heel requiring operative intervention * All Soldiers pending medical board evaluation or punitive action * History of connective tissue disorder (e.g., Marfan's Syndrome, Ehlers-Danlos disease, Rheumatoid Arthritis, etc.) * Leaving the geographical area permanently or for extended periods of time forcing loss to follow up * Treatment for plantar fasciitis with injection within the last 6 months * Surgical indication or internal derangement of the foot * Chronic pain conditions * Pregnancy * Tarsal tunnel syndrome * Baxter's neuritis * Rigid flat foot * Active infection of the Foot overlying the injection area * Use of immunomodulators, immunosuppressives, or chemotherapeutic agents * Allergy or hypersensitivity to any of the proposed treatment medications * Any other clinically significant acute or chronic medical conditions (e.g., bleeding disorder) that, in the judgment of the Investigator, would preclude the use of a PRP or that could compromise patient safety, limit the patient's ability to complete the study, and/or compromise the objectives of the study. * Trauma for this research study is defined as a specific event or mechanism of injury, such as a direct blow or twisting injury of the foot that initiated the onset of heel pain. The insidious onset of heel pain with prolonged running or other physical activity is not defined as a traumatic event.
