Effect of Monochromatic Infrared Energy on Chronic Sciatic Pain

Abstract

Background: Chronic sciatica due to lumbar disc lesion is an important medical and socioeconomic problem that affects the quality of life. The most important symptom is radiating leg pain. Objective: This study was conducted to determine the effect of adding monochromatic infrared energy to selected physical therapy program in the treatment of chronic sciatic pain. Methods: Thirty patients with chronic sciatica due to posterior lumbar disc prolapse L4-5/L5-S1 participated in this study. The patients were assigned into two equal groups (fifteen patients each): Group A (study group) received monochromatic infrared energy along the distribution of sciatic pain, ultrasound therapy on lower back area and Exercise program in the form of (static abdominal, bridging, pelvic rocking and stretching exercise). Group B (control group) received ultrasound therapy on lower back area and the same Exercise program. The treatment sessions were conducted three times per week (every other day) for four successive weeks. Assessment of pain, functional level and back range of motion were done using visual analogue scale, Arabic translated form Oswestry disability index and back range of motion device (BROM) respectively before and after four weeks of treatment. Results: post treatment results revealed that there was a significant improvement in pain intensity in favor to group (A),It was also observed that there was significant improvement in functional abilities in group (A) Back range of motion showed significant improvement of extension and rotation in both groups with no significant improvement in flexion, side bending and rotation to non affected side.Conclusion: Adding monochromatic infrared energy to selected physical therapy program is effective in improving pain, functional abilities and lumbar range of motion (extension and rotation to affected side).
