Shockwave Therapy for Plantar Fasciitis RCT

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.

Study Overview

• Status: Active, not recruiting
• Conditions: Plantar Fascitis
• Intervention / Treatment: Other: Home therapy; Procedure: Radial shockwave therapy; Device: Shockwave therapy device; Procedure: Focused shockwave therapy

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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Visual analog scale pain - morning	Morning pain. This will be assessed on a scale of 0-100, with a higher score representing more pain.	Up to 1 year
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.	Up to 1 year

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
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.	Up to 1 year
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.	Up to 1 year
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.	Up to 1 year
