Physical therapy may be helpful for some people who have plantar fasciitis. It can be especially useful for people who have problems with foot mechanics (biomechanical problems), such as tight Achilles tendons.
A technique called extracorporeal shock wave therapy (ESWT) uses pulsed sound waves to treat plantar fasciitis. Research is still being done, but some studies show that ESWT can help reduce symptoms in plantar fasciitis that has not responded to other treatment.3, 4 New shock wave treatments are being studied. Most types of shock wave therapy, sometimes called "focused" ESWT, require anesthetic. Another type, called radial ESWT, can be done without anesthetic, because the shock wave is more spread out.
