A Study to Confirm the Safety of High Frequency DRG Stimulator in Patients With Chronic Lower Limb Pain

Failed Back Surgery Syndrome Clinical Trial

Official title:
A Single-arm, Open Label, Single Center Pilot Study to Confirm the Safety of Dorsal Root Ganglia (DRG) and Ultrahigh Frequency Spinal Cord Stimulator in Patients With Chronic Lower Limb Pain

Clinical Trial Summary

This study is a prospective, single-arm, open label, single center pilot study to confirm the safety of a ultrahigh frequency DRG stimulator in patients with chronic lower limb pain. The actual trial length is 5 days. Pts will be given ultrahigh frequency pulse stimulation, and VAS will be obtained after 3-4 hours of each stimulation.

Clinical Trial Description

This study is a prospective, single-arm, open label, single center pilot study to confirm the safety of a ultrahigh frequency DRG stimulator in patients with chronic lower limb pain. The actual trial length is 5 days. An initial eligibility screening within Day -14. Pt admitted to hospital on Day 1. The lead implantation is conducted on Day 2, and the 1st treatment starts after anesthesia recovery (Day 2 T1). If VAS >4 at 4 hours after the 1st treatment, the 2nd treatment will be conducted. VAS will be acquired 4 hours after the 2nd treatment. On Day 3, physical examination and vital signs will be collected. If VAS >4, the 3rd treatment will be provided. One hour after the 3rd treatment, the device will be removed and an X-ray will be taken. Three hours after the removal, VAS will be collected and then the patient will be discharged. VAS will be estimated by phone call on Day 4, and the patient will return to OPD for follow up examination on Day 5. The trial is completed on Day 5 visit. ;
