Interventions

Procedure/Surgery : We evaluated the clinical effects of high-voltage (60V) versus standard-voltage (45V) pulsed radiofrequency (PRF) of lumbar (dorsal root ganglion) DRG. In experimental high-voltage

Eligibility

Sex/Gender

All

Inclusion criteria

Inclusion criteria: - age =20 years old - pain intensity =4 out of 11 on the numerical rating scale (NRS) - chronic LRP lasting =12 weeks - previous failure of conservative management such as physiotherapy, exercise therapy, or analgesic medications - lumbar spinal stenosis was confirmed on magnetic resonance imaging (MRI) All eligible patients received conventional diagnostic/therapeutic fluoroscopy-guided transforaminal epidural injection with local anesthetics and steroid before enrollment. Patients who demonstrated pain reduction (=2–points or at least 30% reduction in NRS score) for short duration =6 weeks following epidural injection were finally enrolled.

Exclusion criteria

Exclusion criteria: - patient refusal - age <20 years - unbearable pain >9–points on NRS, pain <4–points on NRS - acute pain of onset lasting <12 weeks - signs of progressive motor weakness or neurologic deficits - allergies to steroids or contrast dyes - coagulopathy - epidural steroid injection within the previous 12 weeks - systemic infection, injection site infection - malignancy

Design outcomes

Primary

Measure	Time frame
number of successful responders to treatment in each group at the 6-month follow-up period. Successful response was defined as: 1) =50% or 4-point reduction in the NRS pain intensity (or) 2) 10-point decrease in ODI, or mean score =6 points on the GPE scale	—

Secondary

Measure	Time frame
NRS pain intensity and ODI at 1, 3, and 6 months post-procedure	—
