[Comparison of the effect of laser and magnetic therapy for pain level and the range of motion of the spine of people with osteoarthritis lower back].

Unlabelled: Increased expression of degenerative disease of the lumbar spine is an onerous task, which reduces the efficiency of the activity and life of many populations. It is the most common cause of medical visits. In 95% of cases the cause of complaints is a destructive process in the course of degenerative intervertebral disc called a lumbar disc herniation. Protrusion of the nucleus pulposus causes severe pain and impaired muscle tone, often more chronic and difficult to master. Successful treatment of lumbar disc herniation constitutes a serious interdisciplinary problem. It is important to properly planned and carried out physiotherapy. Based on the number of non-invasive methods, to reduce muscle tension, mute pain and alleviation of inflammation. It is the treatment safe, effective, and at the same time, which is their big advantage, readily available and cheap. It is worth noting that not every method has the same efficiency. The question that the methods are effective in relieving pain and helping to effectively increase the range of motion led to a comparison of two methods - Low Level Laser Therapy (LLLT) and pulsating magnetic field therapy.

Aim: The aim of the study was to compare the efficacy of LLLT and pulsating magnetic field therapy in combating pain and increase range of motion of the spine of people with degenerative spine disease of the lower back.

Materials And Methods: 120 patients with diagnose lumbar disc herniation whit no nerve roots symptoms. Patients were divided into two Groups: A and B. Group A of 60 patients were subjected to laser therapy (λ=820nm, P=400mW, Ed=6-12 J/cm²) and the second Group B of 60 patients too, to pulsating magnetic fields procedures (5mT, 30 Hz, 15 minutes). Every patient before rehabilitation started and right after it has finished has undergone examination. Subjective pain assessment was carried out using a modified Laitinen questionnaire and Visual Analogue Scale of Pain intensity. Spine mobility was evaluated whit the Schober test and the Fingertip-to-floor-test. The obtained results were subjects to statistical analysis.

Results: Research shows that both low energy laser and pulsating magnetic field physical attributes are effective methods for the treatment of pain and restricted mobility of the spine caused by disc herniation. Careful analysis emphasizes greater efficiency laser for pain. In contrast, a statistically greater improvement in global mobility of the spine, as well as flexion and extension of the lumbar recorded in group B, where the applied pulsating magnetic field.

Conclusions: Both laser and magnet therapy reduces pain and improves mobility of the spine of people with degenerative spine disease of the lower back. Comparison of the effectiveness of both methods showed a greater analgesic effect of laser treatment, and greater mobility of the spine was observed under the influence of pulsating magnetic field therapy.
