title: The effects on postural control and low back pain according to the types of orthoses in chronic low back pain patients.
abstract: [Purpose] This study investigated how types of lumbosacral orthoses applied to patients with chronic lumbar pain affect postural control and low back pain. [Subjects and Methods] Ten subjects were randomly selected and allocated to each a group wearing soft lumbosacral orthoses and a group wearing rigid lumbosacral orthoses. They wore the lumbosacral orthoses for 4 weeks. Pain index and postural control were measured on the first day of wearing lumbosacral orthoses and 4 weeks later. Pain index was evaluated using a visual analogue scale, and postural control was measured using a Balance measurement system. The measurements examined included the overall balance index, anteroposterior balance index, and mediolateral balance index. [Results] There were statistically meaningful within-group differences in all variables, the visual analogue scale, overall balance index, anteroposterior balance index, and mediolateral balance index, in the group wearing soft lumbosacral orthoses. There were meaningful differences in visual analogue scale, overall balance index, and mediolateral balance index in the group wearing rigid lumbosacral orthoses. Furthermore, there was a meaningful difference in anteroposterior balance index between the group wearing soft lumbosacral orthoses and the group wearing rigid lumbosacral orthoses. [Conclusion] The results of the present study showed that wearing soft lumbosacral orthoses was more effective than wearing rigid lumbosacral orthoses.
