Lumbopelvic Movement Control: Effect of Injury History, and the Role of Cortical Control and Its Practical Application 1

The intervention of this group will focus on training the endurance of the core muscle.

Based from the initial test, the subjects will receive either lumbar flexion control exercise or lumbar extension control exercise. They will perform each lumbar movement control exercise in different position. Starting from the lying position, then progressing to sitting, standing with support, and the last level will be standing without support. Each set of movement will be practiced 10 times, totally 10 sets. It will take approximately 5\~8 minutes to finish each movement. The subjects will learn 5\~8 types of the movement every week.

The intervention of this group is mostly same as the movement control training group. The different part is that the first 3 times of the movement will be practiced through image training, so the subjects will not have any real movement, and the last 7 times they will perform the lumbar motor control exercise literally. Each set of movement will be practiced 10 times, totally 10 sets. It will take approximately 5\~8 minutes to finish each movement. The subjects will learn 5\~8 types of the movement every week.
