A Randomized Control Trial of the Effectiveness of Magnetotherapy with Conventional Exercise on Pain, Functions and Lumbar Range of Motion of Persons with Non-specific Low Back Pain

Abstract

Background: Non-specific low back pain is defined as low back pain not attributable to a known cause. Magnetotherapy is an alternative physical agent providing beneficial effects by its ability to penetrate deeply in the tissue in repair process as the patient’s whole body was immersed on a magnetic field. Objectives: To determine the effect of magnetotherapy and conventional exercise on the improvement of pain, Lumbar range of motions and functions in the persons with non-specific low back pain. Method: 60 subjects were randomly divided into 2 groups. group A, received Magnetotherapy and conventional exercise and group 2 received Sham magnetic field with conventional exercise. Pain, Lumbar range of motion and Modified Oswestry disability Index were evaluated at baseline and after 3rd week. Results: There was significant difference found in within group comparison and there was no significant difference found in between group analysis of pain, lumbar range of motion and modified disability index. Conclusion: The magnetotherapy with the dose of 31 mT/10% intensity and 55.55 Hz frequency for 30 minutes have not additional beneficial effect on reduction of pain, lumbar range of motion and functions of the patients with non-specific low back pain.
