Abstract
Background: Low back pain is defined as pain and discomfort, localized below the costal margin and above the inferior gluteal folds, with or without leg pain. Acute low back pain is usually defined as the duration of an episode of low back pain persisting for less than 6 weeks; sub-acute low back pain as low back pain persisting between 6 and 12 weeks; chronic low back pain as low back pain persisting for 12 weeks or more.Patients:forty fivepatients with chronic low back on pain(mean age 40.5± years, height167± cm, weight82.5± kg,and BM 29±kg/m2) participated in this study. Patients,Materials and Methods:Patients were assigned into three equal groups; group (a)receivedtraditional electro-therapy(TENS&Hot pack)andlow levellaser,group (b)receivedtraditional electro therapy(TENS& Hot pack) and McKenzie technique, group(c) received traditional electrotherapy(TENS& Hot pack) program only as a control group; each group being composed of 15chronic low back on painpatients.Data of visual analoguescale (VAS),patient specific functional Scaleand (ROM)scores werecollected from each patient in all groups pre and post physiotherapy program.Results:Statistical analysis using pairedstudent t-test and unpaired student t-test revealed that thereweresignificantdifferencesregarding(VAS)and(PSFS).pre &post treatment in both groups a and b. There was significant difference in improvement in pain, ROM and functional disability in laser group (a) than in McKenzie techniquegroup (b). Conclusion:The physiotherapy program isnot only effective with good result in patients withchronic low back pain, b also would reflect much better result with improvement in pain and function disability if we add low levellaser or McKenzie techniqueto the treatme program.Keywords: McKenzie technique, low level laser, chronic low backpain.
