Description of intervention(s) / exposure
Extracorporeal shock wave therapy (ESWT) is a new technology using a ballistic source to generate pressure waves. The shock waves can be radial or focused. Radial ESWT (rESWT) is a low to medium energy shock wave with a low penetration power compared with focus ESWT. ESWT has commonly been used for the treatment of plantar fasciitis. This study is planned as double-blind, randomized sham-controlled trial. Participants are randomly allocated to two groups: the ESWT group and the sham group. Radial ESWT will be applied in this study. ESWT group will receive radial ESWT one session per week for three weeks. Each session will last for 2-5 minutes. 500 pulses are applied to plantar fascia of the affected side with a frequency of 10 Hertz (Hz) and pressure of 1,8 Bar for the ESWT group. The sham group will recieve sham ESWT one session per week for three weeks. For sham group, we will record the sound of ESWT therapy session. The recorded sound will be turned on but the ESWT probe will be off. The patient will be in the prone position during this treatment. For this reason, the patient can not see the ESWT screen. Each session will last for 2-5 minutes. The people receiving the therapy and the people assessing the outcomes are blinded . Intelect RPW Shockwave by Chattanooga Corporation will be used in this study. Radial ESWT will be applied to all participants by the same physiotherapist at least 10 years of experience in Department of Phsical Medicine and Rehabilitation of Ibni Sina Hospital.

Efficacy
Statistical methods / analysis
Mean, standard deviation, median, min-max and percentile values will be calculated for the socio-demographic and clinical features, primary and secondary outcome measures by descriptive statistics. The one way Anova test will be used to evaluate differences within groups for parametric measures. The Mann Whitney U test will be used to evaluate differences between groups for non parametric measures. The relationship between clinical results and the ultrasonography will be evaluated by Spearman’s test. P value of less than 0.05 was considered as statistically significant. When the power analysis was made by taken Visual Analog Scale as primary outcome variable of the study, Power of the study was calculated to 80% with 10 patients in each group using effect size of 1,00. A total of at least 20 patients are planned to be included in the study.

Summary
Brief summary
Plantar fasciitis is inflammation of plantar fascia. It arises from degeneration, chronic inflammation, microtrauma and axial spondyloarthropathy. 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.
Plantar fasciitis is commonly seen in axial spondyloarthropathy patients. Degenerative and inflammatory pathways play a role together in development of plantar fasciitis in axial spondyloarthropathy patients. Within the available literature there are no study that investigated the effect of ESWT on plantar fasciitis in axial spondyloarthropathy patients. The aim of this study was to evaluate the effectiveness of rESWT in plantar fasciitis in axial spondyloarthropathy patients and to reveal the relationship of this effect with the sonographic features of plantar fascia. This study is planned as double-blind, randomized placebo-controlled trial. Participants are randomly allocated to two groups: the ESWT group and the sham group. Radial ESWT will be applied in this study. This study is planned as double-blind, randomized sham-controlled trial.

Each session will last for 2-5 minutes. 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 sonographic features of plantar fascia. The primary endpoint of this study is to determine a decrease in pain score at least 2 point according to Visual Analog Scale.
