Effect of Electromagnetic Field in Lumbar Disc Prolapse Patients

to investigate the effect of electromagnetic field therapy on sciatica and postural control in lumbar disc prolapse patients BACKGROUND: lumbar disc prolapse is a clinical condition resulting from compression of lumbar nerve roots resulting in decreased postural control and alleviating sciatic pain Pulsed electromagnetic field (PEMF) therapy is an easy, non-invasive, safe, and relatively new treatment method that is used with growing interest in physical and rehabilitation medicine. Historically, the benefits from magnetotherapy have been reported for patients with musculoskeletal and neurological disorders
