Magnetic fields may ease sciatica pain and improve balance

This study tested whether applying low-frequency electromagnetic fields to the lower back could reduce sciatica pain and improve postural control in people with a lumbar disc herniation. Forty-four adults aged 30 to 45 with mild to moderate disc prolapse received either electromagnetic field therapy plus standard physical therapy, or standard therapy alone, three times a week for four weeks. The researchers measured pain, balance, and disability before and after treatment.
