Effect of core program exercise for lumbar extensor strength and pain of the patient with chronic low back pain

Abstract

The purpose of this study is to analyse and to compare the difference and the change between lumbar extension exercise group and lumbar extension exercise with core program exercise group in the area of lumbar extension strength through lumbar extensors strengthening exercise. 50 subjects (CP: 25, NCP: 25) were chosen among chronic low back pain patients between 20 and 60 years old patients who have no previous medical history and no abnormalities in lumbar confirmed by medical experts. Before of research, pre-tested the lumbar extension strength of each group. After 4, 8, 12 weeks of strengthening muscle exercise, retested it and compared the data with initial data. All data acquired in this study were analyzed using SPSS/PC V. 10.0 program for Windows. A t- test was conducted for the comparison of extended muscle strength in the lower back before and after the exercise. In order to see changes in muscle strength at various points (before exercise, 4 week point, 8 week point, 12 week point), a repeatedly measured ANOVA was conducted. To compare the statistical difference during the exercise period, a Tukey HSD was conducted as verification. To identify the level of lower back pain before and after exercise in each group, a paired t-test was conducted. The difference between levels of pain across groups underwent an independent t test and significance level was set at p
