Abstract
Background: Pulsed electromagnetic field therapy is a new device and its efficiency on pain treatment needs to be clarified. Our aim is to investigate the effects of PEMF therapy in combination with conventional physical therapy modalities in patients with chronic non-specific low back pain. Methods: Prospective, randomized, patient-blinded, controlled trial with twenty-nine subjects having chronic nonspecific LBP were randomized into experimental and control groups. The experimental group received PEMF in addition to conventional physical therapy, whereas the control group received a sham electromagnetic field with conventional physical therapy for ten sessions over a four-week period. Pain intensity, functional disability and lumbar range of motion measures were collected. Results: Twenty-seven participants with chronic non-specific LBP completed the study (Experimental group N=13, control group N=14). There were significant within-subject effects and treatment*time effects for pain intensity, ODI, and lumbar ROM results. The change in pain intensity (p=0.004), ODI (p=0.012) and lumbar ROM (p<0.001) were significantly higher in the PEMF group compared to the control group. Conclusions: Compared to conventional physical therapy, combining PEMF therapy with conventional physical therapy provides greater clinical improvement in terms of pain intensity, functional disability and lumbar ROM in subjects with non-specific LBP.
