About

Plantar fasciitis is inflammation of plantar fascia. It arises from degeneration and chronic inflammation. Treatment of plantar fasciitis contains conservative methods like rest, body weight control, stretching exercise, non-steroidal anti-inflammatory drugs and arch supports. ESWT has commonly been used for the treatment of plantar fasciitis. The shock waves can be radial or focused. The aim of this study was to evaluate the effectiveness of the adjuvant use of plantar orthoses in the process of plantar fasciitis when extracorporeal shock waves are applied. The hypothesis porposed was that the use of extracorporeal shock waves together with the use of custom foot orthotics improves the symptoms produced by plantar fasciitis. This study is planned as double-blind, randomized controlled trial. Participants are randomly allocated to two groups: the ESWT group and the custom foot orthotics and ESWT group. Radial ESWT will be applied in this study.

The people receiving the therapy and the people assessing the outcomes are blinded . Both group will recieve ESWT one session per week for three weeks. Each session will last for 2-5 minutes. The primary outcome measure of this study is change in heel pain of affected side assessed using Visual Analog Scale. The secondary outcome measure is Roles y Maudsley scores. The primary endpoint of this study is to determine a decrease in pain score according to Visual Analog Scale.
