A Pulsed Electromagnetic Field Therapy Device for Non-Specific Low Back Pain: A Pilot Randomized Controlled Trial

Area of Science:

• Biomedical Engineering
• Clinical Research
• Pain Management

Background:

• Low back pain (LBP) is a global health issue requiring effective non-pharmacological treatments.
• Pulsed electromagnetic field (PEMF) therapy is explored as a potential non-drug intervention for LBP.
• This study aimed to pilot a clinical trial for a portable PEMF device in individuals with non-specific LBP.

Purpose of the Study:

• To assess the feasibility of a clinical trial for a portable PEMF therapy device.
• To evaluate the safety and preliminary effectiveness of PEMF therapy for non-specific LBP.
• To measure functional capacity changes using the Oswestry Disability Index (ODI).

Main Methods:

• Randomized, double-blind, sham-controlled, parallel-group pilot study.
• Participants received usual care plus active PEMF or sham PEMF.
• Functional capacity (ODI) and pain scores were assessed at baseline, 6, and 12 weeks.

Main Results:

• Forty-two participants were randomized; 25 completed the study.
• Significant ODI improvements were observed in the PEMF group from baseline to 6 weeks (p < 0.001).
• Adverse events were infrequent and mild, indicating good tolerability.

Conclusions:

• A clinical trial of a portable PEMF device for non-specific LBP is feasible.
• The PEMF device demonstrated safety and preliminary efficacy in enhancing function for LBP patients.
• Further research is warranted to confirm these findings in larger populations.
