Radiofrequencies
Pulsed Radiofrequency (PRF) and Radiofrequency Ablation (RFA) are minimally invasive treatments used to reduce chronic pain. PRF works by sending gentle electrical pulses to the nerve at low temperature, without damaging it. It helps to calm the nerve and reduce pain signals, and is mainly used for nerve-related pain (such as sciatica or neuralgia). RFA, instead, uses continuous heat to intentionally block or deactivate the pain nerve.
This produces a longer lasting pain relief by stopping the pain signal at its source. PRF is a safer and reversible option, chosen when the nerve must be preserved. RFA is a more definitive treatment, used especially for joint pain caused by arthritis (spine, knee, hip, sacroiliac joint). Both procedures are performed with ultrasound or X-ray guidance. They are quick, outpatient procedures, with fast recovery. The choice between PRF and RFA depends on type of pain and the patient’s condition.
What to Expect during PRF and RFA Therapy
The treatment is performed under local anesthesia, usually with ultrasound or X-ray guidance for precise needle placement. It usually lasts 15–30 minutes.
Comprehensive Evaluation
A detailed clinical assessment and imaging (ultrasound, MRI, or fluoroscopy when indicated) help determine PRF and RFA are appropriate therapies. This step ensures accurate diagnosis and targeted application
Preparation for the procedure
You may be asked to stop blood thinning medications (such as aspirin or anticoagulants) a few days before treatment only if approved by your doctor.
Guided procedure
Using ultrasound or fluoroscopic guidance, radiofrequency energy is precisely delivered to the targeted area to modulate or block pain signals and improve function.
Comfort & Safety
The procedure is performed under sterile conditions with local anesthesia to minimize discomfort. Patients return home the same day
Recovery & Results
Pain relief may start within a few days to a few weeks, depending on the condition treated. PRF provides gradual pain reduction by modulating pain transmission. RFA usually offers longer-lasting pain relief by blocking pain transmission.
