About
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.
Full 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.
