Prospective multicenter study of 60-day percutaneous peripheral nerve stimulation for chronic low back pain

A prospective, multicenter study evaluated the long-term effects of 60 days of percutaneous peripheral nerve stimulation (PNS) in patients with chronic low back pain (CLBP). After an average follow-up of 4.7 years, the results indicate that this minimally invasive intervention may offer sustained pain relief and improvements in quality of life.

Key study results

• Pain relief: 65% of participants (15 out of 23) reported a clinically significant reduction (≥30%) in low back pain compared to baseline levels.

• Improvements in disability and quality of life: Patients who responded positively to treatment experienced an average 63% decrease in pain intensity, along with significant improvements in disability and quality of life.

• Reduction in invasive interventions: 70% of respondents (16 out of 23) avoided more invasive and costly procedures, such as radiofrequency ablation, neurostimulation implants, or lumbar surgery.

• Patient satisfaction: 61% of participants expressed a preference for stimulation therapy over the use of pain medication.

Clinical implications

These findings suggest that 60-day percutaneous PNS may be an effective and durable therapeutic option for patients with LDD, especially those seeking alternatives to more invasive treatments. In addition, the intervention could be integrated into multimodal treatment strategies, combining it with physical therapy and other conservative therapies.

Additional considerations

Although the results are promising, it is important to note that the study did not include a control group and had a limited sample size. Further research with larger samples and controlled designs is needed to confirm these findings and establish more robust clinical recommendations.
