Pulsed Radiofrequency Versus 5% Dextrose Injection in Chronic Plantar Fasciitis

30. juni 2026 opdateret af: Esra Ülgen Kıratlıoğlu, Ankara City Hospital Bilkent

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.

Detaljeret beskrivelse

Plantar fasciitis is one of the most common causes of chronic heel pain in adults. It may impair walking pattern, daily activities, social life, and work-related functioning. Although conservative treatments are commonly used as first-line therapy, symptoms may become chronic in a considerable proportion of patients.

Dextrose injection is a regenerative injection treatment used in chronic musculoskeletal pain conditions. It is thought to stimulate local tissue healing responses through controlled inflammatory and proliferative mechanisms. Pulsed radiofrequency is a minimally invasive, non-neurodestructive radiofrequency technique used for pain control. Both pulsed radiofrequency and dextrose injection are used in clinical practice for resistant chronic plantar fasciitis; however, comparative data between these two approaches are limited.

This study will be conducted as a prospective, two-center, two-arm, parallel-group randomized controlled trial in the Physical Medicine and Rehabilitation clinics of Ankara Bilkent City Hospital and Adana City Hospital. Participants with chronic plantar fasciitis will be randomized in a 1:1 ratio using the sealed-envelope method. The investigator responsible for randomization will know the allocation, while the outcomes assessor will be blinded to treatment allocation. Blinding of the interventionists will not be possible due to the nature of the procedures.

Participants in the pulsed radiofrequency group will receive ultrasound-guided pulsed radiofrequency treatment at baseline. Participants in the 5% dextrose group will receive ultrasound-guided 5% dextrose injection around the medial calcaneal insertion of the plantar fascia using the peppering technique, with 0.1-0.2 mL administered at each entry point. Dextrose injections will be performed in three sessions at 3-week intervals.

All participants will receive a home-based plantar fascia stretching exercise program. Exercises will be demonstrated by a physiotherapist, and participants will be instructed to perform the exercises twice daily for 12 weeks. Participants will be monitored for possible adverse events or complications for at least 30 minutes after the procedure. Clinical outcomes will be assessed at baseline, 3 weeks, 6 weeks, and 12 weeks.

Intervention / Behandling
Eksperimentel: Ultrasound-Guided Pulsed Radiofrequency Treatment
Participants in this group will receive ultrasound-guided pulsed radiofrequency treatment at baseline. Clinical follow-up assessments will be performed at 3 weeks, 6 weeks, and 12 weeks. All participants will also receive a home-based plantar fascia stretching exercise program.
Procedure: 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.
Aktiv komparator: Ultrasound-Guided 5% Dextrose Injection
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.
Procedure: 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.

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.
