Peripheral nerve field stimulation (PNFS) in chronic low back pain: a prospective multicenter study

Area of Science:

• Neurology
• Pain Management
• Medical Devices

Background:

• Chronic low back pain (cLBP) poses a significant challenge in healthcare.
• Current treatments for cLBP have limitations in long-term efficacy and safety.

Purpose of the Study:

• To evaluate the long-term efficacy and safety of peripheral nerve field stimulation (PNFS) for managing cLBP.

Main Methods:

• A prospective, multicenter observational study involving 118 patients with cLBP.
• Patients underwent a trial period before permanent PNFS system implantation in the lower back.
• Pain, functional levels, quality of life, and medication usage were assessed pre- and post-implantation (1, 3, 6 months).

Main Results:

• Statistically significant improvements were observed in pain (visual analog scale), disability (Oswestry Disability Questionnaire), depression (Becks Depression Inventory), and overall health (Short Form-12).
• Significant reductions in opioid, NSAID, and anti-convulsant medication use were noted.
• Complications requiring surgery occurred in 9.6% of patients; coverage of painful areas appeared crucial for efficacy.

Conclusions:

• PNFS is confirmed as an effective therapy for cLBP management.
• The study demonstrates significant improvements in multiple pain-related aspects.
• PNFS offers a safe and effective long-term treatment option with minimal complications.
