Abstract
Background: Low back pain occurs between the lumbar vertebrae and the sacral bone and is affected by factors that often occur when trying to perform a particular operation or during a collision. The purpose of this study was to investigate the effects of long-term wearing of lumbar brace on the electromyography frequency spectrum of trunk and lower limbs in low back pain older adults with pronated feet during walking.
Methods: This research was of a semi-experimental type. Fifteen patients with low back pain and pronated feet were selected as an experimental group (age: 68.3 ± 2.7 years) and Fifteen patients with low back pain and pronated feet were selected as a control group (age: 69.0 ± 3.9 years).The lumbar brace used in this research was Sacro Lumbar Support, BB-OPPO 2065 model, Taiwans. The electrical activity of the lower limb and trunk muscles were recorded by the electromyography system during walking in both pre and post-test. All statistical analysis was done on SPSS software by two way ANOVA analyses test at significant level of 0.05.
Results: The findings in the experimental group demonstrated that the frequency content of the gastrocnemius medialis muscle during post-test was significantly lower than that during the pre-test (P=0.002). Also, two external oblique (P=0.007) and rectus abdominus (P<0.001) muscles showed a significant increase in their frequency content during post-test than that in the test pre-test.
Conclusion: Results demonstrated that using of lumbar brace can increase abdominal muscle activity in patients with low back pain and pronated feet.
