Comparison of Ultrasound-Guided Pulsed Radiofrequency and 5% Dextrose Injection in Patients With Chronic Plantar Fasciitis: A Randomized Controlled Trial
This prospective, two-center, randomized controlled clinical trial aims to compare the effectiveness of ultrasound-guided pulsed radiofrequency and 5% dextrose injection in patients with chronic plantar fasciitis. Eligible participants will be randomized into two parallel groups. One group will receive ultrasound-guided pulsed radiofrequency treatment, and the other group will receive ultrasound-guided 5% dextrose injection using the peppering technique. All participants will receive a home-based plantar fascia stretching exercise program. Outcomes will be assessed at baseline, 3 weeks, 6 weeks, and 12 weeks after treatment. The primary outcome will be pain intensity measured by the Numeric Rating Scale. Secondary outcomes will include foot function, activity-related pain, ankle-hindfoot function, and health-related quality of life.
• Diagnosis of chronic plantar fasciitis based on medical history and physical examination
• Heel pain resistant to conservative treatment for at least 12 weeks
• Age between 18 and 70 years
• Willingness to participate in the study and provide written informed consent
