Ultrasound-Guided Pulsed Radiofrequency TreatmentUltrasound-Guided 5% Dextrose Injection

Ultrasound-Guided Pulsed Radiofrequency Treatment: Ultrasound-guided pulsed radiofrequency treatment will be applied for chronic plantar fasciitis. Participants will be monitored for at least 30 minutes after the procedure for possible adverse events or complications.

Ultrasound-Guided 5% Dextrose Injection: Ultrasound-guided 5% dextrose injection will be applied around the medial calcaneal insertion of the plantar fascia using the peppering technique, with 0.1-0.2 mL administered at each entry point. The treatment will consist of three sessions performed at 3-week intervals.

Study summary

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.

Primary outcome measure(s)

Change in Heel Pain Intensity Assessed by Numeric Rating Scale — Baseline, 3 weeks, 6 weeks, and 12 weeks after treatment
Heel pain intensity will be assessed using the Numeric Rating Scale. Resting pain, pain during plantar fascia stretching, and pain with pressure will be evaluated on an 11-point scale from 0 to 10, where 0 indicates no pain and 10 indicates the worst imaginable pain. Higher scores indicate greater pain intensity.
