Study aim
-
Comparative Effectiveness Of Ultrasound-Guided Dextrose injection And Radial Extracorporeal Shock Wave Therapy For The Treatment Of Chronic Plantar Fasciitis
-
Design
-
Clinical trial with control group, with parallel groups, blinding is not done and randomization is done by closed envelopes.
-
Settings and conduct
-
This study was performed on patients with chronic plantar fasciitis referred to the PMR Clinics of IUMS . After performing physical examinations and the presence of tenderness in the medial part of the heel to confirm the diagnosis,lateral heel X-ray and diagnostic ultrasound will be performed.Patients are randomly assigned to be divided into two groups of 19 people. The treatment is performed at Firoozgar Hospital by a PMR resident.

Participants/Inclusion and exclusion criteria
-
Main inclusion criteria: age 18 to 65 years, point tenderness of medial calcaneal tubercle, Heel pain with first step in the morning or after prolonged standing , thickness of plantar fascia greater than 4 mm in ultrasound and resistant to supportive treatments for at least three months
Main exclusion criteria:coagulopathy,history of foot and ankle fracture or surgery,recent 6 weeks corticosteroid injection, bilateral plantar fasciitis, pregnancy and receive plantar fasciitis treatment in the last 6 months
-
Intervention groups
-
In the first group, 1.5 cc dextrose 20% plus 0.5 cc lidocaine 0.5% will be injected into the maximum thickness plantar fascia under ultrasound-guided in-plane injection technique.The cotrol group receive 3 sessions of low energy weekly.Shockwave Radial-SW type with Shock 2000 number, energy of 0.2 to 0.3 mJ / mm2 and frequency of 4 Hz focused on the Tenderness region.

Main outcome variables
-
The severity of morning and daily pain by Visual Analog Scale (VAS),Evaluation of foot and ankle function by Foot and Ankle Ability Measure (FAAM),Thickness of plantar fascia by Ultrasonography
