Abstract

PURPOSE
The paper presents an intervention for clinical applications in the future by examining the effects of 3D stabilization exercise on patients with lumbar instability, which causes problems in the muscles and balance, and analyzing the effects of balanced lumbar muscles on the static balance.
METHODS
After collecting samples randomly from thirty patients with lumbar instability, fifteen patients selected for 3D stabilization exercise were placed in the stability group and fifteen patients selected for Swiss ball exercise were placed in the ball exercise group. The intervention program was applied for thirty minutes a session, once a day, three days a week for four weeks. Before the intervention, the lumbar muscle activity and static balance were measured. After four weeks, they were re-measured in the same way and the data were analyzed.
RESULTS
In relation to the within-group changes in muscle activity, all groups except for the LEO and REO groups showed significant differences. Regarding the between-group changes in muscle activity depending on the left and right difference, ES, RA, and TrA but not EO showed significant differences. In addition, there were significant differences in the between-group change in static balance.
CONCLUSION
3D stabilization exercise improves the muscle activity by promoting a balanced posture of lumbar muscles and changing senses, such as a proprioceptor but this had a positive influence on the static balance by controlling the balance of muscles.
