To investigate immediate effects of biofeedback training on motor control performance in participants with nonspecific chronic low back pain. RCT was conducted. The training group received isolated and co-contraction training of trunk stabilizers in lying on the left side, sitting on stool and sitting on a gymnastic ball, while the control group was asked to rest comfortably on a chair. Trunk muscles response time during rapid arm movement test was recorded using surface electromyography. Two-way ANOVA and Bonferroni post hoc test were used to detect changes within and between groups. In the training group, the trunk muscles response times were significantly decreased after training when compared with those in the control group (p<0.05). Trunk stabilizer training has a beneficial effect on motor response time of the trunk muscles. The long-term effects of exercise should be further considered with a larger sample size.
