Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
PRF Group
This group will undergo 42°C high-voltage pulsed radiofrequency treatment.
High-voltage pulsed radiofrequency
The manual PRF mode of the pain treatment generator will be turned on, the upper temperature limit will be set at 42°C, the PRF output voltage will be gradually increased to the highest voltage the patient can tolerate, and the patient will be treated for 360 s. After the treatment, 1.4 ml of a mixture of 0.4 mL of normal saline and 1 mL of 1% plain lidocaine will be injected through the needle of the cannula, and before the needle being removed, 0.5 mL of normal saline will be injected.
Nerve Block Group
This group will undergo nerve block treatment with steroid and local anesthesia.
Nerve block
The radiofrequency generator will be set at the sensory stimulating mode, and the lowest frequency of 0.2 V will be used for 360s-sham PRF treatment, after which 1.4 mL of a mixture of 2 mg of dexamethasone sodium phosphate and 1 mL of 1% plain lidocaine will be slowly injected through the radiofrequency treatment cannula needle. Before the needle being removed, 0.5 mL of normal saline will be injected.
