Here’s one research article behind the treatment for patients with heel pain due to chronic plantar fasciitis.
*Gollwitzer, H. et al. Clinically relevant effectiveness of focused Extracorporeal shock wave therapy in the treatment of chronic plantar fasciitis: a randomized, controlled multicenter study. J Bone Joint Surg Am. 2015 May 6;97(9):701-8. doi: 10.2106/JBJS.M.01331.
The objective of the present study was to test whether focused Extracorporeal shock wave therapy is effective in relieving chronic heel pain diagnosed as plantar fasciitis. Two hundred and forty-six patients (98.4%) were available for intention-to-treat analysis at the twelve-week follow-up. There was a significant difference (p = 0.0027, one-sided) in the reduction of heel pain in the Extracorporeal shock wave therapy group (69.2%) compared with the placebo therapy group (34.5%). Extracorporeal shock wave therapy was also significantly superior to the placebo therapy for the Roles and Maudsley score (p = 0.0006, one-sided).
